[Experience with the use of posterior pituitary hormones in memory disorders of different etiology].

Results of using vasopressin and pituitrin in 20 patients with memory disturbances of various genesis (due to circulatory disturbances in the vertebrobasilar system, cerebral atherosclerosis, neurasthenia, brain concussion, epilepsy) are reviewed. The therapeutic efficacy of the hormones was evaluated with the use of a complex of psychophysiological methods. Objective changes in the patients' neurological status and subjective state were taken into account. A high therapeutic efficacy of the hormones in the treatment of amnestic syndromes is demonstrated.

[An outpatient clinic for memory disorders; initial experiences].

The department of neurology of the Academisch Medisch Centrum started an outpatient memory clinic in 1987 for patients aged 65 and older. Its specific aims are: assessment of elderly patients with memory problems, treatment where appropriate, and advice; clinical research; teaching and training. The clinic has run full-time since 1990. The approach is multidisciplinary. We describe our findings in the first 75 patients who were referred by their general practitioners because of forgetfulness or possible dementia: 72 of them had a complete investigation; 30 patients were not demented; three could be reassured because their performance was within normal limits. Four patients were depressed and they improved on therapy. Forty-two patients were demented. All had a CT scan and comprehensive blood tests but a curable cause for the dementia syndrome was never identified. This result was expected on account of the probably low frequency of 'reversible' causes and patient selection. Secondary prevention was important when a vascular component contributed to the pathogenesis of the mental deterioration (n = 6). Even when no curable condition was found, clarity about diagnosis and prognosis was important not only to the relatives but also to the general practitioner in planning the future management of the patient. Fifty-five of the 72 patients were older than 65 years which means that we do see the patients we are particularly interested in. The clinic offers facilities for clinical research. In the project 'Diagnostiek bij dementiesyndroom' (Diagnostics in dementia syndrome) we investigate the utility of ancillary investigations in relation to the outcome in demented patients.

[Combined therapies in family practice and hospitals. A controlled clinical study of a population of 162 patients with criteria of age-related memory disorders].

OBJECTIVES: To assess the combination of drug and cognitive therapy on age-associated memory impairment (AAMI). PATIENTS AND METHODS: A double-blind randomized trial was performed involving 162 patients with age-associated memory impairment selected and followed by their general practitioners. Two intervention methods-a drug and a cognitive therapy-were assessed in combination. Three randomized parallel groups of 54 patients each, aged 55 years and over, were followed and treated for 3 months. After a placebo washout period of 10 days, one group received 2.4 g of piracetam, another group, 4.8 g and the third, a placebo. RESULTS: A total of 135 patients, 45 in each group, completed the study. Combined therapy was most effective in patients whose baseline performance on memory tests was lowest. The best results were observed with piracetam combined with memory training. This result confirmed by the global impression of the principal investigator was in agreement with findings of previous double-blind placebo-controlled trials assessing the combined effect of drug treatment and memory training. CONCLUSION: This result confirmed by the global impression of the principal investigator was in agreement with findings of previous double-blind placebo-controlled trials assessing the combined effect of drug treatment and memory training.

Memory disorders as a function of traumatic brain injury. Word completion, recall of words and actions.

The memory performance of a group with traumatic brain injury and a matched control group was assessed using the following methods (a) word completion, (b) immediate free, final free and final cued recall of words and (c) immediate free and final free recall of subject-performed tasks (SPTs) and SPTs without motor action (SPTs-WA). The brain-injured (BI) group was significantly inferior relative to the control group in all recall tests except immediate free recall of words. No difference was revealed in the word completion test. The BI-group benefitted less by cues presented either at retrieval (final cued recall of words) or at the time of encoding already built-in in the stimulus (SPTs and SPTs-WA). The results were discussed in terms of the neuropathological background of the patients in the BI-group suggesting that frontal dysfunction could play a critical role. When comparing the tests within the BI-group, however, the performance was better when cues were present and especially so for long-term memory. Motor activity also facilitated long-term memory. Finally, an attempt was made to specify conditions for guidance in the construction of training programmes.

[Attitude of the elderly to the etiology of memory disorders].

PURPOSE: The early recognition of dementia assumes increasing importance. Lay beliefs on the causes of loss of memory play a major part in this regard as they have shown to determine help-seeking behaviour. METHOD: 720 persons aged 75 or older were questioned on their beliefs on the causes of cognitive deficits in the context of the Leipzig Longitudinal Study of the Aged (LEILA 75+). RESULTS: Almost one-third of the respondents mentioned exclusively biological causes, vascular lesions coming first. One quarter of those questioned ascribed memory deficits to non-biological factors. Every tenth person suspected that they result from a combination of both. One quarter of the elderly did not know any answer. DISCUSSION: The results are contrasted with outcomes of epidemiological dementia research. It is argued that increasing and better quality information of the public are urgently required.

[Free radical mechanisms of memory disorders of toxic origin and experimental therapy of the condition].

Influence of the pesticides deltametrin and dichlophos on memory processes and activity of the antioxidative enzymes superoxide dismutase (SOD) and catalase in the brain and blood of female rats was studied. Xenobiotics disturbed processes of formation and storage of signs of memory, which were tested in the conditional reaction of passive avoidance and in the conditional reaction of active avoidance; they also lowered SOD activity (but not catalase) in the brain (deltametrin by 25%, dichlophos by 21%) 3 h after their injection to the animals. Indices of SOD activity and blood catalase didn't change. SOD inhibition is suggested to be a result of the action of biotransformation product of deltametrin and dichlophos molecules on it, since in in vitro experiments pesticides don't exert influence on the inhibition kinetics of epinephrine autooxidation by brain homogenates. Prophylactic use of alpha-tocopherol or unithiol optimizes the processes of learning and memory in rats, intoxicated with these toxicants; a more marked antiamnestic, effect is observed in the combined injection of these preparations.
