Vascular dementia versus dementia of Alzheimer's type: do they have differential effects on caregivers' burden?

OBJECTIVES: We investigated homecare patients with dementia of Alzheimer's type (DAT; n = 36) or vascular dementia (VD; n = 36) and their care-providing relatives regarding clinical and psychosocial variables to determine whether DAT and VD impose different burdens on caregivers. METHOD: All patients were diagnosed according to ICD-10 criteria. The diagnoses were confirmed by internal medical, clinical-neurological, and psychiatric parameters. The severity of the dementias was graded according to the Global Deterioration Scale (GDS). Caregiving relatives responded to the Behavioral Pathology in Alzheimer's Disease Rating Scale (BAD), the Blessed Dementia Scale (BDS), and the Screen for Caregiver Burden (SCB). RESULTS: Analyses revealed that caregivers' burden (SCB), disease symptoms and personality changes of patients (BAD), and the patients' inability to cope with everyday tasks (BDS) were sharply higher for DAT than for VD patients in the group with severe dementia. Concerning patients with mild or moderately severe disease, scores in the DAT group were similar or lower than those in the VD group. CONCLUSION: In early stages, VD patients impose a greater burden on relatives than do patients with DAT. In severe stages this relationship undergoes a reversal, with relatives of DAT patients experiencing the burden more adversely than those of VD patients. The differences in the onset and course characteristics, as well as the specific differences between these two types of dementia with respect to caregiver burden factors, call for their diagnostic separation and the development of specific homecare support systems for family caregivers.

[Psychogenic reaction: course and prognostic factors]. / Die psychogene Reaktion: Verlauf und prognostische Faktoren.

A follow-up was made of ninety patients with a diagnosed psychogenic reaction (adjustment disorder) fourteen years after the index hospitalisation. Contrary to expectation, at the follow-up only half of the patients showed no symptoms of the illness. Approximately a quarter of the patients suffered from a more serious illness (drug dependence, schizophrenia or organic mental disorder) than the index diagnosis. The other quarter showed symptoms of a psychogenic disorder (neurotic disorder, personality disorder, adjustment disorder). A number of factors which describe the course of the illness leading to the index hospitalisation permit a prediction of the outcome of the disease.

First hospitalized versus rehospitalized patients with an affective disorder or schizophrenia: differences in long-term course and outcome.

A comparison of course and outcome in schizophrenics and patients with unipolar affective disorders revealed significant differences not only between the two groups but also between first hospitalized and rehospitalized patients within each group. While schizophrenics fared worse in almost all parameters at the end of the 14-year follow-up period, within each group overall course and outcome were also poorer for rehospitalized versus first hospitalized patients. The poorest course was shown by rehospitalized schizophrenics. Future studies on course and outcome should differentiate between first and rehospitalized patients.

The validity of the ICD-10 classification of recurrent affective disorders: do endogenous and psychogenic depressions form a homogeneous diagnostic group?

Fifty-five hospital-treated patients with the ICD-10 diagnosis of 'recurrent depressive episode(s)' were classified according to the Newcastle Depressive Diagnostic Scale as having either psychogenic (n = 25) or endogenous (n = 30) depression and interviewed using several inventories on personality and psychopathology (Composite International Diagnostic Interview, Symptom Check List, Inventory of Interpersonal Problems, IIP, NEO Five-Factor Personality Inventory, Social Adjustment Scale, Questionnaire of the Motivation to Seek Psychotherapy). Except for the IIP, individual subscales disclosed significant differences between the two groups. In light of these results, the grouping of these two disorders into one diagnostic group in the ICD-10 is critically discussed.

Motivation to seek psychotherapy in patients with recurrent depressive disorder.

Fifty-five hospital-treated patients with the ICD-10 diagnosis of recurrent depressive episode(s) were classified according to the Newcastle Depressive Diagnostic Scale as having either psychogenic (n = 25) or endogenous (n = 30) depression and interviewed using the Composite International Diagnostic Interview and the Questionnaire for Assessment of Motivation to Seek Psychotherapy. The two groups were found to differ significantly from one another in two Motivation to Seek Psychotherapy subscales ("layman's etiology" and "general expectations from therapy"). The motivation to seek psychotherapy was greater in patients with psychogenic depression than in patients with endogenous depression. Nonetheless, psychotherapy is indispensable in treating endogenous depression, especially for patients under situational stress or at risk of suicide.
