The frequency of depression was assessed in 43 chronic schizophrenic patients during an acute exacerbation phase of schizophrenia. The dexamethasone suppression test was administered to all patients. Depressive symptomatology showed a prevalence from 16.3% for moderate symptoms to 23.3% for mild ones. Depressive symptoms occurred concurrently with the psychotic picture and resolved as the psychosis remitted. Depressive symptoms were not relative to age, sex, duration of illness, DST cortisol levels, drug dosages and extrapyramidal side effects while basal cortisol levels were negatively correlated with basal Hamilton score.

Depressive symptoms are frequently diagnosed in patients with schizophrenia. The coexistence of mood disorders and criteria of schizophrenia may result in the diagnosis of schizoaffective disorders. Depressive symptoms can also be recognized after the acute phase of schizophrenia or after neuroleptic treatment which results in the diagnosis of postpsychotic or postneuroleptic depression. Sometimes, depressive symptoms can be misinterpreted; it happens because depressive symptoms can resemble negative symptoms of schizophrenia or neuroleptic side effects. The principles of therapeutic approach to depressive symptoms in schizophrenia have been discussed. Taking into consideration the hypothetical role of the serotoninergic system in the genesis of schizophrenia, special attention has been paid to the drugs selectively acting on this system. The results of the use of fluoxetine as co-treatment with neuroleptics, published by various authors have been presented.

This study examined depressive symptoms in acute schizophrenic episodes and their relationship to neuroleptic treatment. Sixty-three depressed and 62 non-depressed acutely exacerbated schizophrenic patients were evaluated with the Brief Psychiatric Rating Scale, the Scale for the Assessment of Positive Symptoms, the Simpson-Angus Extrapyramidal Scale, and the Hamilton Rating Scale for Depression. Subjects were then randomly assigned to different haloperidol plasma levels and followed for 3 weeks. Overall, depression improved with treatment of the acute psychosis, but a positive association between extrapyramidal side effects and depressive symptoms emerged over time. Depressive symptoms tended to be positively related to haloperidol plasma levels. The results suggest that depressive symptoms in schizophrenia are heterogeneous in origin; while neuroleptics can ameliorate depressive symptoms inherent in the acute schizophrenic episode, they can also contribute to depression.

1. A prevalence of depressive symptomatology, ranging from 25% to 80% has been reported during the course of schizophrenia. 2. Depressive symptoms were assessed in 144 schizophrenic patients (DSM IV) during an acute exacerbation phase. 3. Depressive symptoms showed a prevalence ranging from 5.5% (severe clinical pictures) to 54.8 (mild clinical pictures). 4. The authors did not find a correlation between depressive symptoms per se and the presence of negative psychotic symptoms. Depression may be linked not so much to negative symptoms but to the psychotic state itself. 5. Depressive symptomatology concurrently occurred with schizophrenic relapses and improved together with the psychotic clinical picture, independently of the neuroleptic drug employed. Haloperidol, haloperidol decanoate and fluphenazine decanoate all showed a similar improvement of depressive symptoms. 6. L-sulpiride showed a trend to be most effective on depressive symptomatology in comparison to the other neuroleptics.

This study investigated the relationship between the perception of family functioning and depressive symptomatology in individuals with eating disorders (EDs). Subjects were evaluated by diagnostic clinical interview using DSM-III-R criteria for EDs, the Schedule for Affective Disorders and Schizophrenia-Lifetime Version (SADS-L), and two self-report measures, the Beck Depression Inventory (BDI) and the Family Assessment Device (FAD). A significant association was found between self-reported depressive symptomatology and perceived poor family functioning. Subjects with bulimia nervosa (BN) reported a significantly more dysfunctional family background than subjects with anorexia nervosa (AN). In our sample, the presence of self-reported depressive symptomatology was a more powerful predictive variable for perceived family dysfunction than the diagnosis of affective disorder. Also, the diagnosis of BN was a more consistent predictor of dysfunctional family interaction than the diagnosis of affective disorder. Depressive symptoms and EDs seem to play different roles in the way in which they contribute to dysfunctional family patterns.

Depressive symptoms in psychotic disorders are of high relevance but seem to be heterogeneous when assessed with a standard rating scale. The present analysis is a replication study on the dimensionality of the Bech-Rafaelsen Melancholia Scale (BRMES) in acutely psychotic patients with substantial depression defined according to a functional approach across the nosological borders of schizophrenia with major affective symptoms, schizoaffective disorder, depressed subtype, and major depression with psychotic features. The baseline data of 123 patients participating in a multicenter pharmacological trial were evaluated with structural equation models. A previously reported three-dimensional model of the BRMES comprising the facets retardation, depressive core symptoms, and accessory depressive symptoms was cross-validated by confirmatory factor analysis (CFA). The three-dimensional model proved to be superior to one-, two-, or four-factor models with respect to goodness-of-fit (goodness-of-fit index [GFI] = 0.91 and comparative fit index [CFI] = 0.89) and parsimony (adjusted GFI [AGFI] = 0.85). When comparing the present model with the previously reported model, a highly satisfactory correspondence emerged (CFI = 0.87). The results corroborate our previous findings that depression-like symptoms in acutely psychotic patients assessed by the BRMES can best be represented by a three-dimensional model and should not be treated as a homogeneous syndrome.

There is an increasing need for practical instruments that can rapidly and accurately assess the effectiveness of treatments for mental illness in clinical settings. Symptom rating scales used in clinical research are too complex and time-consuming to be useful in these settings. In contrast, single-item global measures of severity such as the Clinical Global Impression-severity scale (CGI) and the Global Assessment of Function scale (GAF) are brief and easy to complete, but little is known about their relationship with the specific symptoms of severe mental illnesses. In this study, we examine the extent to which CGI and GAF scores reflect the severity and the change in severity of positive, negative, depressive, and agitation symptoms in a sample of 102 schizophrenia inpatients at the University of Michigan Medical Center. At admission, positive symptoms were the strongest correlates of both CGI and GAF scores, followed by negative symptoms, and agitation. Depressive symptoms did not correlate significantly with either global measure. The three symptom scores together explained 58% of the variation in CGI and 39% of the variation in GAF. A similar pattern of association was found for the scores measured at discharge and for the relationships between the change in global measures and change in specific symptom clusters. Thus, by demonstrating that single-item global measures, particularly the CGI, can be reasonably good indicators of psychopathology, this study suggests that these measures may be practical tools for routine monitoring of the effectiveness of treatments for severe mental illness in community settings.

Depressive symptoms and syndromal depression commonly occur in patients with schizophrenia. Schizophrenia is also associated with aggression directed at self and others. For this article, the available literature regarding the efficacy of clozapine, risperidone, olanzapine, quetiapine, and ziprasidone in the treatment of depression, hostility, and suicidality in patients with schizophrenia was reviewed. These studies suggest that atypical antipsychotics may exert therapeutic effects on depression and hostility as well as psychosis and that clozapine and olanzapine may reduce suicidality in patients with schizophrenia. These therapeutic actions appear to represent additional advantages of atypical antipsychotics compared with standard agents.

Depressive symptoms are unspecific and occur in several psychiatric disorders. Sleep disturbances are also frequently present in depressed patients. As a consequence, it has been established that a number of modulations of the sleep-wake cycle can have an antidepressive effect. Total sleep deprivation or deprivation in the second half of the night have proven successful. The main limitation of the otherwise well tolerated treatment is the short duration of the antidepressive effect, which is mostly reversed in nearly all patients after the following night's sleep. New approaches are to shift the timing of sleep to earlier to ensure a possible longer-lasting effect. In clinical praxis the following manipulations should not be used: sleep deprivation in the first half of the night (not successful), REM-sleep deprivation (experimental setting), induced sleep prolongation (negative risk-benefit-ratio). In addition to patients with affective disorders sleep deprivation has proved relevant in patients with schizophrenia (depressed and/or with predominantly negative symptoms) and premenstrual dysphoric disorder. Very few side effects have been reported. Although many hypotheses have been tested, the mechanism of action underlying the antidepressive effect of sleep deprivation is still unknown.

Subjective and objective evaluation of pharmacological treatment was made in 105 schizophrenic in-patients. PANSS and Calgary scale as well as Van Putten scale were used. Fifty-four percent of subjects received classic neuroleptics and 46%--new atypical drugs for an average period of 8 weeks. The severity of schizophrenic symptoms during treatment as well as subjective evaluation of first effects of the drug did not differ among subjects treated with classic or atypical drugs. Depressive symptoms decreased significantly during treatment with atypicals but not with classic drugs. Also a significant decrease of depression was found under olanzapine treatment. The severity of neuroleptic-induced side-effects did not differ in both groups. Neurological side effects were more prominent in subjects after 4 weeks of therapy with risperidone, in comparison to patients receiving olanzapine. Forty-seven per-cent of patients showed a dysphoric reaction to the first dose of medication. After treatment with atypical drugs, better subjective evaluation of pharmacotherapy correlated with less severe general and depressive schizophrenia symptoms. Patients' better evaluation of olanzapine treatment correlated with less severe schizophrenic general symptomatology. The subjective evaluation of treatment was better in patients with less severe neurological side-effects of atypical drugs (including olanzapine but not risperidone) and less severe autonomic side-effects of classic drugs. The evaluation of pharmacotherapy made by patients' family members did not correlate with subjects' opinions after distribution of the first dose of the drugs, but correlated significantly with patients' opinion after 8-weeks of treatment. The treatment received by the patients was judged better by the family members if less severe neurological side-effects were present.
