Certain psychiatric complications are associated with various stages of PD. The possible causes known to date are analysed. Depression, isolated cognitive impairments, pharmacotoxic psychosis and dementia-related changes are the predominant mental disorders in PD. PD and depression syndrome occur very frequently in old age. Behaviour and mimicry of patients with progressive PD and of patients with depression syndrome are sometimes so similar that the two conditions can be differentiated only by long-term monitoring. In addition, PD and depression may occur simultaneously. However, frequency and intensity of depressive phases do not differ in PD patients and aged-matched depressed patients without PD. About one third of patients hospitalized at the neurological department of the Geriatric Hospital Lainz require antidepressant drug treatment. Similar percentages were found for other chronic cerebral and extracerebral diseases in the aged. Major depressions are independent of the parkinsonian disability and can be successfully managed only by antidepressant medication. Pharmacotoxic psychoses are not only serious conditions, they also reveal the limitations of therapeutic options. The unusual frequency of such acute psychoses, i.e. 30 to 60% in the terminal stages of the disease, indicates a special relation between antiparkinson medication and increasing neurotransmitter disturbances. Permanent pronounced depression in the sense of DSM III is not one of the symptoms of typical PD. States of dementia occur only in connection with a second or third cerebral pathology, mostly in combination with SDAT and MID.

The dexamethasone suppression test (DST) and the depressive attributional style questionnaire (ASQ) were administered to 105 depressed patients prior to participation in a double-blind outpatient study and to 29 normal controls. The depressed patients were classified into three groups (1) met criteria for both research diagnostic criteria for definite endogenous depression and DSM III melancholia; (2) met criteria for neither, and (3) met criteria for one but not both. The group that met criteria for both RDC endogenous depression and DSM-III melancholia had a statistically greater frequency of abnormal DST versus the group that met neither criteria and the normal controls. With regard to ASQ, patients who met both criteria had statistically higher bad event internality scores but statistically lower bad event stability and globality scores as opposed to the group that met neither criteria. In general, normal controls had significantly lower bad event ASQ scores than the three depressive groups. There was no correlation between ASQ and DST, as both DST suppressors and nonsuppressors had similar ASQ scores and there was no correlation between ASQ bad event attributions and initial severity of depression.

Major depression (MD) is common in patients with coronary artery disease (CAD). Some of these patients have a history of prior depressive episodes, whereas others experience their first episode around the same time that their CAD is diagnosed. The purpose of this study was to determine whether there are systematic differences between these two subgroups of depressed patients. Of 39 patients with recently diagnosed CAD who met DSM-III-R criteria for MD, 17 (44%) had a prior history of MD. This subgroup had a higher proportion of females (p less than 0.003), more severe depression (p less than 0.004), were marginally younger (p = 0.08), and had slightly less severe CAD (p = 0.07) compared with those with no prior history of MD. These results support the hypothesis that there may be two distinctive subtypes of MD in patients with CAD. Additional studies are needed to determine whether these subgroups differ with respect to course, treatment, and relationship to the coronary artery disease.

Data concerning 331 subjects participating in a longitudinal study on anxiety disorders were collected over the first 6 months of the study. Preliminary analyses of somatic treatment according to diagnoses and study site were conducted. The comorbidity of one anxiety disorder with other DSM-III-R diagnoses and other types of anxiety disorders was extensive. Patients with panic disorder received significantly more treatment with a benzodiazepine than patients without panic disorder. Fewer than five percent of the sample were treated with a monoamine oxidase inhibitor. Comorbid depression increased the likelihood of treatment with a newer non-MAOI (non-monoamine oxidase inhibitor), nontricyclic antidepressant. Results suggest a strong effect of treatment site on the pharmacotherapy offered.

Pediatricians are sufficiently concerned about the importance of "subthreshold" mental health problems to have joined in the movement to create a Diagnostic and Statistical Manual of Mental Disorders for the primary care setting (DSM-PC), with the aim of establishing a set of criteria for disorders that do not meet the severity requirements of the American Psychiatric Association's current DSM. An element in the argument for a DSM-PC is that there is a high level of functional impairment and need for treatment in children with mental health problems below the DSM threshold. This was examined in 789 children aged 7 through 11 recruited sequentially from the pediatric clinics of a health maintenance organization, compared with 134 age-matched children seen in a psychiatric clinic. Of the pediatric patients, 22% had one or more clinical-level DSM-III diagnoses, and 42% had a threshold-level disorder, compared with 65% and 34%, respectively, of psychiatric patients. In the pediatric sample, most threshold, and all clinical-level disruptive behavior disorders were associated with significant levels of functional impairment. There was little evidence that emotional disorders (anxiety and depression), even at the clinical level, were associated with significant impairment. One implication of these results is that pediatricians can expect one child in five to have a clinical-level DSM disorder. A second is that intervention at low levels of disruptive behavioral symptomatology may be needed if significant functional impairment is to be avoided.

Forty-eight patients with DSM-III-R Panic Disorder underwent a hyperventilation provocation Test (HVPT). Twenty-four patients rated the symptoms induced during the HVPT as similar to those occurring during panic attacks in daily life. Contrary to the classical hyperventilation model of panic, no differences were found in respiratory physiology between recognizers and non-recognizers before and during voluntary hyperventilation. Moreover, recognizers and non-recognizers reported comparable levels of panic and hyperventilation symptoms and state anxiety during panic attacks in daily life. Ten of the recognizers also had a panic attack during the HVPT, independent of any differential CO2 alterations. Compared to non-panickers, panickers obtained higher scores for agoraphobia and depression. On the basis of these results, it is concluded that recognizers or panickers do not show a tendency towards hyperventilation, but that reports of severe panic and hyperventilation symptoms are more closely related to the level of anxiety. These results are more consistent with the cognitive model of panic, which emphasizes the patient's tendency to interpret somatic symptoms catastrophically.

This study reports the prevalence and risk factors of depression in a large representative community sample of adult Korean immigrants in Toronto, Canada. The Center for Epidemiologic Studies-Depression scale was used to measure depression by applying DSM-III criteria. Results in general suggest few differences between the immigrant community and the larger communities in Canada and the United States. Depressive syndrome was present in 4.5% of the sample, a prevalence similar to rates reported by the Epidemiologic Catchment Area studies. The risk factors associated with depression in larger populations were also found to be related to depression in this sample. Gender, marital status, intention to re-migrate, and social support were the most powerful correlates of depressive syndrome. In summary, Korean immigrants in Toronto are not exceptionally vulnerable to depression, and the social support from informal ethnic networks at the time of arrival has long-lasting effects on their mental health. Future research should focus on how the informal social supports available at the time of arrival are maintained by immigrants and the precise ways in which they exert long-term protective effects.

The Center for Epidemiologic Studies-Depression scale was used to measure depression by applying DSM-III criteria to a community sample of 860 adult Korean immigrants residing in Toronto, Canada. A total of 2.6% of men (95% confidence interval, 1.1% to 4.1%) and 6.7% of women (95% confidence interval, 4.3% to 9.1%) manifested depressive syndrome, rates not substantially different from those reported in North American community populations. The study also identified the subgroups in which the gender differences in depression were the greatest. Both the role demand (or double burden) and power explanations of gender differences might be supported. The mental health implications of social roles, including gender role, may be better understood from cross-cultural or multicultural perspectives.

Depersonalization disorder is classified in DSM-III-R (APA 1987) as a dissociative disorder characterized by altered perception or experience of the self. To date, there are no known reports of the neurobiological features of this disorder. We report clinical and biological correlates in a patient with depersonalization disorder previously unresponsive to a variety of anticonvulsant, monoamine oxidase inhibitor, and tricyclic antidepressant trials, but for whom fluoxetine partially reduced depersonalization symptoms, but not associated anxiety and depression. Neurophysiological, neuroanatomical and neuropsychological findings revealed left hemispheric frontal-temporal activation and decreased left caudate perfusion. These findings suggest a similarity to the neuropsychiatric data reported in obsessive-compulsive disorder patients.

The relation between depression and epilepsy was evaluated in 96 epileptic out-patients. We found that 50% of epileptic patients fulfilled the DSM-IIIR criteria for depression. The Hamilton Rating Scale for Depression, the Beck Self Depression Inventory and the Zung Anxiety Scale were also used in all patients. The patients with partial seizures with complex semiology (CPS) were more depressed than the patients with primary generalized epilepsy and with partial seizures with elementary semiology. A significant increase in the level of anxiety was also found in the group with CPS compared to the other two groups. No correlations were noted between severity of depression and duration of epilepsy, seizure frequency, socio-economic status, education, and family history of depressive illness. No relationship was observed between anticonvulsant drug levels and depression. We failed to confirm an association between side of epileptic lesion and severity of depression. We suggest that depression in epileptic patients does not represent a psychological reaction to a particular cognitive or physical impairment, but is in some way related to the type of epilepsy.
