PSYCH PEARLS 3

PSYCH PEARLS 3
51-year-old woman presents with an episode of dysphoria, sleep difficulty, psychomotor agitation, and rumination about mistakes she has made in her life. She has delusions of guilt about indirectly causing the deaths of many people. She has a history of two previous episodes with similar symptoms, but no history of manic episodes. Between episodes, she is asymptomatic. Which of the following is the most likely diagnosis
Major depressive disorder, recurrent
The history and findings are most suggestive of major depressive disorder, recurrent, with mood-congruent psychosis.
The individual has depressive episodes with mood-congruent psychotic features.
The absence of a history of manic episodes makes bipolar disorder unlikely.
Dysthymic disorder is less likely because it is usually characterized by long periods of depressed mood, but without the full features of a depressive episode or psychosis present in this case.
Schizoaffective disorder is diagnosed only when psychosis persists for at least 2 weeks in the absence of mood episodes.
In schizophrenia , psychotic symptoms and emotional blunting persist in the absence of mood symptoms and are usually more prominent than any associated mood pathology.
Schizoaffective disorder is one of the most confusing and controversial diagnostic categories in psychiatry.
People suffering from schizoaffective disorder experience a chronic roller-coaster ride of symptoms and problems that may be more difficult to cope with than either of its parent diseases, schizophrenia or affective disorders (formerly known as mood disorders).
Researchers have identified two subtypes of schizoaffective disorder: bipolar type and depressive type.
Bipolar type is associated with the presence of manic or mixed episodes.
Such episodes bring on sudden elation, euphoria, or extreme irritability to the point of serious impairment.
Depressive type is associated with major depressive episodes.
Depressive episodes are often characterized by feelings of worthlessness, hopelessness or indifference, and inability to concentrate or remember details, and thoughts of death or suicide attempts.
Like schizophrenia and affective disorders, schizoaffective disorder is caused by a chemical imbalance in the brain’s neurotransmitters.
Since schizoaffective disorder bears a close resemblance to both schizophrenia and affective disorders, people with the illness experience a combination of symptoms associated with both diseases.
To be diagnosed with schizoaffective disorder a person must not meet the criteria for either schizophrenia or affective disorder.
However, a person must have at one time experienced both a schizophrenic and a mood disturbance and, at another time, experienced psychotic symptoms without affective symptoms.
These symptoms include…
Psychotic Symptoms
Delusions
Hallucinations
Disorganized thinking
Agitation
Lack of drive or initiative
Social withdrawal
Apathy
Affective Symptoms
Extreme mood swings from mania to depression
Hyperactivity
Thoughts of death or suicide
Decreased need for sleep
Acute psychosis
Loss of appetite
This disorder is characterized by the presence of one of the following:
Major Depressive Episode (must include depressed mood)
Manic Episode
Mixed Episode
as well as the presence of at least two of the following symptoms, for at least one month:
delusions
hallucinations
disorganized speech (e.g., frequent derailment or incoherence)
grossly disorganized or catatonic behavior
negative symptoms (e.g., affective flattening, alogia, avolition)
(Only one symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person's behavior or thoughts, or two or more voices conversing with each other.)
The occurrence of the delusions or hallucinations must be in the absence of any serious mood symptoms for at least 2 weeks. The mood disorder, however, must be present for a significant minority of the time. The symptoms of this disorder also can not be better explained by the use or abuse of a substance (alcohol, drugs, medications) or a general medical condition (stroke).
Like schizophrenia, schizoaffective disorder usually begins in early adulthood. Although research on the disorder is scarce, women seem to suffer from the illness more often than men.
Schizoaffective disorder responds to treatment with antimanics (such as lithium), antidepressants, and antipsychotics.
Major Depressive Episode
SYMPTOMS
A major depressive episode is not a disorder in itself, but is a part of another disorder, most often major depressive disorder or bipolar disorder.
A person who suffers from a major depressive episode must either have a depressed mood or a loss of interest or pleasure in daily activities consistently for at least a 2 week period. This mood must represent a change from the person's normal mood; social, occupational, educational or other important functioning must also be negatively impaired by the change in mood. A major depressive episode is also characterized by the presence of a majority of these symptoms:
depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad or empty) or observation made by others (e.g., appears tearful). (In children and adolescents, this may be characterized as an irritable mood.)
markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day
significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day.
insomnia or hypersomnia nearly every day
psychomotor agitation or retardation nearly every day
fatigue or loss of energy nearly every day
feelings of worthlessness or excessive or inappropriate guilt nearly every day
diminished ability to think or concentrate, or indecisiveness, nearly every day
recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide
Depression (Major Depressive Disorder)
SYMPTOMS
A person who suffers from a major depressive disorder must either have a depressed mood or a loss of interest or pleasure in daily activities consistently for at least a 2 week period. This mood must represent a change from the person's normal mood; social, occupational, educational or other important functioning must also be negatively impaired by the change in mood. A depressed mood caused by substances (such as drugs, alcohol, medications) is not considered a major depressive disorder, nor is one which is caused by a general medical condition. Major depressive disorder cannot be diagnosed if a person has a history of manic, hypomanic, or mixed episodes (e.g., a bipolar disorder) or if the depressed mood is better accounted for by schizoaffective disorder and is not superimposed on schizophrenia, a delusion or psychotic disorder.
This disorder is characterized by the presence of the majority of these symptoms:
depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad or empty) or observation made by others (e.g., appears tearful). (In children and adolescents, this may be characterized as an irritable mood.)
markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day
significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day.
insomnia or hypersomnia nearly every day
psychomotor agitation or retardation nearly every day
fatigue or loss of energy nearly every day
feelings of worthlessness or excessive or inappropriate guilt nearly every day
diminished ability to think or concentrate, or indecisiveness, nearly every day
recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide
The symptoms are not better accounted for by bereavement, i.e., after the loss of a loved one, the symptoms persist for longer than 2 months or are characterized by marked functional impairment, morbid preoccupation with worthlessness, suicidal ideation, psychotic symptoms, or psychomotor retardation.
Manic Episode
SYMPTOMS
A manic episode is not a disorder in and of itself, but instead is a part of other disorders, most usually bipolar disorder.
It is characterized by a time period of an elevated, expansive or notably irritable mood, lasting for at least one week. This disorder must be sufficiently severe to cause difficulty or impairment in occupational, social, educational or other important functioning and can not be better explained by a mixed episode. Symptoms also can not be the result of substance use or abuse (alcohol, drugs, medications) or caused by a general medical condition. A majority of the following symptoms is also present:
inflated self-esteem or grandiosity
decreased need for sleep (e.g., feels rested after only 3 hours of sleep)
more talkative than usual or pressure to keep talking
flight of ideas or subjective experience that thoughts are racing
attention is easily drawn to unimportant or irrelevant items
increase in goal-directed activity (either socially, at work or school, or sexually) or psychomotor agitation
excessive involvement in pleasurable activities that have a high potential for painful consequences (e.g., engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments)
Bipolar Disorder
SYMPTOMS
Bipolar disorder is often not recognized by the patient, relatives, friends, or even physicians. An early sign of manic-depressive illness may be hypomania--a state in which the person shows a high level of energy, excessive moodiness or irritability, and impulsive or reckless behavior.
Hypomania may feel good to the person who experiences it. Thus, even when family and friends learn to recognize the mood swings, the individual often will deny that anything is wrong.
In its early stages, bipolar disorder may masquerade as a problem other than mental illness. For example, it may first appear as alcohol or drug abuse, or poor school or work performance.
If left untreated, bipolar disorder tends to worsen, and the person experiences episodes of full-fledged mania and clinical depression.
One of the usual differential diagnoses for bipolar disorder is that the symptoms (listed below) are not better accounted for by Schizoaffective Disorder and is not superimposed on Schizophrenia, Schizophreniform Disorder, Delusional Disorder, or Psychotic Disorder Not Otherwise Specified.
And as with nearly all mental disorder diagnoses, the symptoms must cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
Specific symptoms of various types of this disorder follow.
Bipolar I Disorder
Bipolar I Disorder actually is a number of separate diagnoses, depending upon the type of mood most recently experienced.
Bipolar I Disorder, Single Manic Episode
Presence of only one Manic Episode and no past Major Depressive Episodes.
Note: Recurrence is defined as either a change in polarity from depression or an interval of at least 2 months without manic symptoms.
Bipolar I Disorder, Most Recent Episode Hypomanic
Currently (or most recently) in a Hypomanic Episode.
There has previously been at least one Manic Episode or Mixed Episode.
Bipolar I Disorder, Most Recent Episode Manic
Currently (or most recently) in a Manic Episode.
There has previously been at least one Major Depressive Episode, Manic Episode, or Mixed Episode.
Bipolar I Disorder, Most Recent Episode Mixed
Currently (or most recently) in a Mixed Episode.
There has previously been at least one Major Depressive Episode, Manic Episode, or Mixed Episode.
Bipolar II Disorder
Presence (or history) of one or more Major Depressive Episodes and at least one Hypomanic Episode. Additionally, there has never been a Manic Episode or a Mixed Episode.
Mixed Episode
SYMPTOMS
A mixed episode is not a disorder, but rather a part of a mental disorder, most commonly bipolar disorder. It consists of meeting the criteria for both a manic episode as well as a major depressive episode nearly every day for at least a full week.
Like all mental disorders, the disturbance must be severe enough to cause distress or impairment in social, occupational, education or other important functioning and is not better accounted for by the physiological effects of substance use or abuse (alcohol, drugs, medications) or a general medical condition.

diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others)
recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committing suicide
The symptoms do not meet criteria for a Mixed Episode
The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., hypothyroidism).
The symptoms are not better accounted for by Bereavement, i.e., after the loss of a loved one, the symptoms persist for longer than 2 months or are characterized by marked functional impairment, morbid preoccupation with worthlessness, suicidal ideation, psychotic symptoms, or psychomotor retardation.
(2) Criteria for Manic Episode
A distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least 1 week (or any duration if hospitalization is necessary).
During the period of mood disturbance, three (or more) of the following symptoms have persisted (four if the mood is only irritable) and have been present to a significant degree:

The symptoms do not meet criteria for a Mixed Episode
The mood disturbance is sufficiently severe to cause marked impairment in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.
The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication, or other treatment) or a general medical condition (e.g., hyperthyroidism).
(3) Criteria for Mixed Episode
The criteria are met both for a Manic Episode and for a Major Depressive Episode (except for duration) nearly every day during at least a 1-week period.
The mood disturbance is sufficiently severe to cause marked impairment in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.

Schizoaffective Disorder
European Description

The ICD-10 Classification of Mental and Behavioural Disorders
World Health Organization, Geneva, 1992
F25 Schizoaffective Disorder
These are episodic disorders in which both affective and schizophrenic symptoms are prominent within the same episode of illness, preferably simultaneously, but at least within a few days of each other. Their relationship to typical mood (affective) disorders and to schizophrenic disorders is uncertain. They are given a separate category because they are too common to be ignored. Other conditions in which affective symptoms are superimposed upon or form part of a pre-existing schizophrenic illness, or in which they coexist or alternate with other types of persistent delusional disorders, are classified under the appropriate category. Mood-incongruent delusions or hallucinations in affective disorders do not by themselves justify a diagnosis of schizoaffective disorder.
Patients who suffer from recurrent schizoaffective episodes, particularly those whose symptoms are of the manic rather than the depressive type, usually make a full recovery and only rarely develop a defect state.
Diagnostic Guidelines
A diagnosis of schizoaffective disorder should be made only when both definite schizophrenic and definite affective symptoms are prominent simultaneously, or within a few days of each other, within the same episode of illness, and when, as a consequence of this, the episode of illness does not meet criteria for either schizophrenia or a depressive or manic episode. The term should not be applied to patients who exhibit schizophrenic symptoms and affective symptoms only in different episodes of illness. It is common, for example, for a schizophrenic patient to present with depressive symptoms in the aftermath of a psychotic episode (see post-schizophrenic depression). Some patients have recurrent schizoaffective episodes, which may be of the manic or depressive type or a mixture of the two. Others have one or two schizoaffective episodes interspersed between typical episodes of mania or depression. In the former case, schizoaffective disorder is the appropriate diagnosis. In the latter, the occurrence of an occasional schizoaffective episode does not invalidate a diagnosis of bipolar affective disorder or recurrent depressive disorder if the clinical picture is typical in other respects.
F25.0 Schizoaffective Disorder, Manic Type
A disorder in which schizophrenic and manic symptoms are both prominent in the same episode of illness. The abnormality of mood usually takes the form of elation, accompanied by increased self-esteem and grandiose ideas, but sometimes excitement or irritability are more obvious and accompanied by aggressive behaviour and persecutory ideas. In both cases there is increased energy, overactivity, impaired concentration, and a loss of normal social inhibition. Delusions of reference, grandeur, or persecution may be present, but other more typically schizophrenic symptoms are required to establish the diagnosis. People may insist, for example, that their thoughts are being broadcast or interfered with, or that alien forces are trying to control them, or they may report hearing voices of varied kinds or express bizarre delusional ideas that are not merely grandiose or persecutory. Careful questioning is often required to establish that an individual really is experiencing these morbid phenomena, and not merely joking or talking in metaphors. Schizoaffective disorders, manic type, are usually florid psychoses with an acute onset; although behaviour is often grossly disturbed, full recovery generally occurs within a few weeks.
Diagnostic Guidelines
There must be a prominent elevation of mood, or a less obvious elevation of mood combined with increased irritability or excitement. Within the same episode, at least one and preferably two typically schizophrenic symptoms (as specified for schizophrenia [F20], diagnostic guidelines (a) - (d)) should be clearly present.
This category should be used both for a single schizoaffective episode of the manic type and for a recurrent disorder in which the majority of episodes are schizoaffective, manic type.
Includes:
* schizoaffective psychosis, manic type
* schizophreniform psychosis, manic type
F25.1 Schizoaffective Disorder, Depressive Type
A disorder in which schizophrenic and depressive symptoms are both prominent in the same episode of illness. Depression of mood is usually accompanied by several characteristic depressive symptoms or behavioural abnormalities such as retardation, insomnia, loss of energy, appetite or weight, reduction of normal interests, impairment of concentration, guilt, feelings of hopelessness, and suicidal thoughts. At the same time, or within the same episode, other more typically schizophrenic symptoms are present; patients may insist, for example, that their thoughts are being broadcast or interfered with, or that alien forces are trying to control them. They may be convinced that they are being spied upon or plotted against and this is not justified by their own behaviour. Voices may be heard that are not merely disparaging or condemnatory but that talk of killing the patient or discuss this behaviour between themselves. Schizoaffective episodes of the depressive type are usually less florid and alarming than schizoaffective episodes of the manic type, but they tend to last longer and the prognosis is less favourable. Although the majority of patients recover completely, some eventually develop a schizophrenic defect.
Diagnostic Guidelines
There must be prominent depression, accompanied by at least two characteristic depressive symptoms or associated behavioural abnormalities as listed for depressive episode; within the same episode, at least one and preferably two typically schizophrenic symptoms (as specified for schizophrenia), diagnostic guidelines (a)-(d) should be clearly present.
This category should be used both for a single schizoaffective episode, depressive type, and for a recurrent disorder in which the majority of episodes are schizoaffective, depressive type.
Includes:
* schizoaffective psychosis, depressive type
* schizophreniform psychosis, depressive type

Basic Principles
Both drug and psychosocial therapies are necessary to successfully treat schizoaffective disorder. Because of the unemployment, poverty, and homelessness that often complicates schizoaffective disorder, drug therapy alone usually is insufficient. Drug therapy usually can stop the patient's psychosis, but often only social and occupational rehabilitation therapies can overcome the associated unemployment, poverty and homelessness. Recovering from schizoaffective disorder is an extremely lonely experience, and these patients require all the support that their families, friends, and communities can provide.
Schizoaffective disorder appears to be a combination of a thought disorder, mood disorder, and anxiety disorder. Thus the medical management of
schizoaffective disorder oftens requires a combination of antipsychotic, antidepressant, and antianxiety medication. Unfortunately, after the first year of treatment, only a minority of schizoaffective outpatients remain on their oral medications. Thus long-acting, depot antipsychotic medications that last 2-4 weeks between injections (e.g., depot haloperidol, pipotiazine, or fluphenazine) usually are required to overcome this noncompliance problem.
Hospitalization
Treatment of an acutely psychotic patient often requires psychiatric hospitalization. The presence of adequate family or social supports will often shorten the length of this hospitalization, or permit the psychotic patient to be treated solely on an outpatient basis.
Antipsychotic Drugs
Antipsychotic medications are the treatment of choice. Evidence to date suggests that all of the antipsychotic drugs (except clozapine) are similarly effective in treating psychoses, with the differences being in milligram potency and side effects. Clozapine (Clozaril) has been proven to be more effective than all other antipsychotic drugs, but its serious side-effects limit its use.
Individual patients may respond to one drug better than another, and a history of a favorable response to treatment with a given drug in either the patient or a family member should lead to use of that particular drug as the drug of first choice. If the initial choice is not effective in 2-4 weeks, it is reasonable to try another antipsychotic drug with a different chemical structure.
Often an agitated, psychotic patient can be calmed in 1-2 days on antipsychotic drugs. Usually the psychosis gradually resolves only after 2-6 weeks of a high-dose antipsychotic drug regimen. A common error is to dramatically reduce antipsychotic drug dosage just as the patient improves or leaves hospital. This error almost guarantees a relapse. Major reduction in antipsychotic drug dosage should be avoided for at least 3-6 months after hospital discharge. Decreases in antipsychotic drug dosage should be done gradually. It takes at least 2 weeks for the body to reach a new equilibrium in antipsychotic drug level after a dose reduction.
Sometimes patients view the side-effects of the antipsychotic drugs as being worse than their original psychosis. Thus clinicians must be skillful in preventing these side-effects. Sometimes these side-effects can be removed by simply reducing the patient's antipsychotic drug dosage. Unfortunately, such reduction in drug dosage often causes patients to relapse back into psychosis. Therefore clinicians have no choice but to use the following treatments for these antipsychotic side-effects:
1. Acute Dystonic Reactions:
These reactions are of abrupt onset, sometimes bizarre, frightening muscular spasms mainly affecting the musculature of the head and neck. Sometimes the eyes go into spasm and roll back into the head.
Such reactions usually take place within the first 24 to 48 hours after therapy has begun or, in a small number of cases, when dosage is increased. Males are more vulnerable to the reactions than females, and the young more so than the elderly.
High doses are more likely to produce such effects.
Although these reactions respond dramatically to the intramuscular injection of antihistamines or anti-parkinson agents, they are frightening and are best avoided by starting with lower antipsychotic drug dosages.
Anti-parkinsonian drugs (e.g., benztropine, procyclidine) should be prescribed whenever antipsychotic drugs are started. Usually these anti-parkinsonian drugs can be safely stopped in 1-3 months.
2. Akathisia:
Akathisia is experienced as an inability to sit or stand still, with a subjective feeling of anxiety. Beta-adrenergic antagonists (e.g., atenolol, propranolol) are the most effective treatment for akathisia. These beta-blockers usually can be safely stopped in 1-3 months. Akathisia may also respond benzodiazepines (e.g., clonazepam, lorazepam), or to anti-parkinson drugs (e.g., benztropine, procyclidine).
3. Parkinsonism:
Akinesia, a key feature of parkinsonism, may be overlooked, but if the patient is asked to walk briskly for some 20 paces, diminution of the swing of the arms can be noted, as can loss of facial expression.
These parkinsonian side-effects of antipsychotic drugs usually respond to the addition of an anti-parkinson drug (e.g., benztropine, procyclidine).
4. Tardive Dyskinesia:
Between 10 to 20 percent of patients receiving antipsychotic agents develop some degree of tardive dyskinesia. It is now known that many cases of tardive dyskinesia are reversible and that many cases do not progress.
Early signs of tardive dyskinesia are mostly seen in the area of the face.
Movements of the tongue inside the buccal cavity that consist of retraction of the tongue on its longitudinal axis or irregular rotation around the longitudinal axis, with frequent movements in lateral directions, are thought to be the earliest signs.
Choreoathetoid movement of the fingers and toes may also be observed, as may respiratory dyskinesia associated with irregular breathing and, perhaps, grunting.
Tardive dyskinesia is thought to result from dopamine receptor supersensitivity following chronic receptor blockade by the antipsychotic agent.
Anticholinergic drugs do not improve tardive dyskinesia and may make it worse.
The recommended treatment of tardive dyskinesia is to lower the dosage of antipsychotic drugs and hope for gradual remission of the choreoathetoid movements. Increasing the dosage of an antipsychotic briefly masks the symptoms of tardive dyskinesia, but symptoms will reappear later as a reflection of the progression of receptor supersensitivity.
5. Neuroleptic Malignant Syndrome:
Antipsychotic agents potentiate anticholinergic drugs, and toxic psychosis may occur. This confusional state usually appears early in treatment and, more commonly, at night and in elderly patients. Withdrawal of the offending agents is the treatment of choice. Antipsychotic drugs often interfer with body temperature regulation. Therefore, in hot climates this situation may result in hyperthermia and in cold climates hypothermia.
The neuroleptic malignant syndrome is an exceedingly rare but potentially fatal condition characterized by parkinsonian-type rigidity, increased temperature, and altered consciousness.
The syndrome is ill-defined and overlaps with hyperpyrexia, parkinsonism, and neuroleptic-induced catatonia. Coma may develop and result in rare terminal deaths.
This syndrome is reported most often in young males, may appear suddenly, and usually lasts 5 to 10 days after cessation of neuroleptics.
There is no treatment; therefore, early recognition and discontinuation of antipsychotic drugs, followed by supportive therapy, are indicated.
6. Hypersomnia And Lethary:
Many patients on antipsychotic drugs sleep 12-14 hours per day and develop marked lethary. Often these side-effects disappear when treated with the newer serotonergic antidepressants (e.g., fluoxetine, trazodone). These antidepressants usually are given for 6 or more months.
7. Other Side-Effects:
Depressed S-T segments, flattened T-waves, U-waves, and prolonged Q-T intervals may be caused by antipsychotic drugs. This situation is cause for concern, is more liable to occur with low potency agents, particularly thioridazine, and could increase vulnerability to arrhythmia.
It is not possible to say to what extent antipsychotic drugs are involved in sudden death. Serious reactions to antipsychotic drugs are rare. Photosensitivity reactions are most common with chlorpromazine; vulnerable patients should wear protective screens on their exposed skin.
Pigmentary retinopathy is associated with thioridazine and may impair vision if not detected. This complication occurred at dosages below the considered safe limit of 800 mg. Dosages of above 800 mg are, therefore, not recommended.
Antipsychotic agents may affect libido and may produce difficulty in achieving and maintaining erection. Inability to reach orgasm or ejaculation and retrograde ejaculation have been reported.
Antipsychotics also may cause amenorrhea, lactation, hirsutism, and gynecomastia.
Weight gain may be more liable to occur with any antipsychotic drug which causes hypersomnia and lethargy.
Studies suggest that many antipsychotic drugs taken during pregnancy do not result in fetal abnormalities.
Because these agents reach the fetal circulation, they may affect the newborn, thus producing postnatal depression and also dystonic symptoms.
"Drug Holidays" From Antipsychotic Drugs
It was once thought that patients should take a "drug holiday" by periodically stopping their antipsychotic drugs for a few weeks every year. This practice is no longer recommended. Research has shown that these "drug holidays" increase the risk of relapse of schizoaffective disorder, as well as increase the risk of tardive dyskinesia.
Antidepressant Drugs
The older (tricyclic) antidepressants often worsen schizoaffective disorder. However, the newer (serotonergic) antidepressants (e.g., fluoxetine, trazodone) have dramatically benefited many apathetic or depressed schizoaffective patients.
Antianxiety Drugs
Benzodiazepines (e.g., lorazepam, clonazepam) often can dramatically reduce the agitation and anxiety of schizoaffective patients. This is often especially true for those suffering from catatonic excitement or stupor. Clonazepam also is an effective treatment for akathisia.
When Not To Use Antipsychotic Drugs
Development of a Neuroleptic Malignant Syndrome is an absolute contraindiction to the use of antipsychotic drugs. Likewise, development of severe tardive dyskinesia is a contraindication to the use of all antipsychotic drugs, except clozapine (Clozaril) and reserpine.
Lithium
If the patient does not respond to antipsychotic treatment alone, lithium may be added for 2 to 3 months on a trial basis. Combined lithium-antipsychotic drug therapy is helpful in a significant percentage of patients.
Anticonvulsants
The addition of carbamazepine, clonazepam, or valproate to antipsychotic drug refractory schizoaffective patients has been reported to sometimes be effective. This benefit is more often seen in patients suffering from bipolar disorder. Acute psychotic agitation or catatonia often responds to clonazepam.
Other Drugs
The use of megavitamins and special diets have apparently little or no effect for schizoaffective patients.
Electroconvulsive Therapy
Electroconvulsive therapy (ECT) has been used effectively in small percentage of schizoaffective patients, particularly those of the catatonic subtype. Patients with an illness duration of less than 1 year are most responsive. This therapy offers little hope for lasting improvement in chronic schizoaffective patients.
Psychosocial Treatment
Basic Principles
Untreated schizoaffective disorder will often leave a patient friendless, penniless, and homeless. Thus circumstances often force schizophenic patients to rely heavily on their family or psychiatric group homes. There is frequently an inverse relationship between the stability of their living situation and the amount of antipsychotic drugs they require.
Supportive Psychotherapy
Traditional insight-oriented psychotherapy is not recommended in treating schizoaffective patients, whose egos are too fragile. Supportive therapy, which may include advice, reassurance, education, modeling, limit setting, and reality testing, is generally the therapy of choice.
Psychotherapy can have toxic effects, especially when there is a negative transference. One of the toxic effects of psychotherapy is dependency. A pushing, intrusive approach may make withdrawn patients worse.
Group Therapy
Group therapy, combined with drugs, produces somewhat better results than drug treatment alone, particularly with schizoaffective outpatients. Positive results are more likely to be obtained when group therapy focuses on real-life plans, problems, and relationships; on social and work roles and interaction; on cooperation with drug therapy and discussion of its side effects; or on some practical recreational or work activity. This supportive group therapy can be especially helpful in decreasing social isolation and increasing reality testing.
Family Therapy
Family therapy can significantly decrease relapse rates for the schizoaffective family member. In high-stress families, schizophenic patients given standard aftercare relapse 50-60% of the time in the first year out of hospital. Supportive family therapy can reduce this relapse rate to below 10 percent. This therapy encourages the family to convene a family meeting whenever an issue arises, in order to discuss and specify the exact nature of the problem, to list and consider alternative solutions, and to select and implement the consensual best solution. Self-Help groups in which family members of schizoaffective patients discuss and share issues, have been particularly helpful in this regard.
Behavior Therapy
Behavior therapy in hospital often involves rewarding desired behaviors with specific privileges, such as ground privileges or weekend passes.
When the schizoaffective patient is no longer floridly psychotic or distractible, behavior therapy usually can successfully teach much needed social and occupational skills.
Patients with concurrent schizophrenic and mood symptoms are often treated with antipsychotics plus antidepressant or thymoleptic drugs. The authors review the literature on treatment of two overlapping groups of patients: those with schizoaffective disorder and those with schizophrenia and concurrent mood symptoms.
METHOD: MEDLINE searches (from 1976 onward) were undertaken to identify treatment studies of both groups, and references in these reports were checked. Selection of studies for review was based on the use of specified diagnostic criteria and of parallel-group, double-blind design (or, where few such studies addressed a particular issue, large open studies). A total of 18 treatment studies of schizoaffective disorder and 15 of schizophrenia with mood symptoms were selected for review.
RESULTS: For acute exacerbations of schizoaffective disorder or of schizophrenia with mood symptoms, antipsychotics appeared to be as effective as combination treatments, and there was some evidence for superior efficacy of atypical antipsychotics. There was evidence supporting adjunctive antidepressant treatment for schizophrenic and schizoaffective patients who develop a major depressive syndrome after remission of acute psychosis, but there were mixed results for treatment of subsyndromal depression. There was little evidence to support adjunctive lithium for depressive symptoms and no evidence concerning its use for manic symptoms in patients with schizophrenia.
CONCLUSIONS: Empirical data suggest that both groups of patients are best treated by optimizing antipsychotic treatment and that atypical antipsychotics may prove to be most effective. Adjunctive antidepressants may be useful for patients with major depression who are not acutely ill. Careful longitudinal assessment is required to ensure identification of primary mood disorders.
