Predictors for negative attitudes toward subjects with epilepsy: a representative survey in the general public in Austria.

PURPOSE: To assess knowledge of and attitudes toward epilepsy in the Austrian general public and to identify independent predictors of negative attitudes. METHODS: A survey consisting of a representative sample of 2,128 Austrian adults was commissioned. A questionnaire similar to the ones used in earlier studies in other countries was used. The independent influence of socioeconomic variables and of knowledge and concepts about epilepsy on attitudes were analyzed by using logistic stepwise regression procedure. RESULTS: Nearly 10% of respondents expressed negative attitudes toward people with epilepsy. These figures are similar to those of other studies performed in comparable societies. In addition to being male and of low socioeconomic background, having little theoretical knowledge about epilepsy, misconceptions of epilepsy as a form of insanity, and no personal acquaintance with someone with epilepsy independently predispose to unfavorable attitudes toward epilepsy. CONCLUSIONS: Information campaigns on epilepsy are likely to improve attitudes toward epilepsy when they target misconceptions about epilepsy and when they offer opportunities for personal acquaintance with people with epilepsy.

Arnold Pick's concept of dementia.

Arnold Pick (1851-1924) provided the first description of the neurodegenerative disease associated with his name; but his importance to the field of neuroscience goes far beyond this eponymous gift. His view that the process of dementia should be seen as a mosaic of circumscribed neuropsychological deficits and not as a diffuse degradation of mental abilities is essential for progress in a cognitive neuropsychological approach to the study of dementias.

Apraxia, mechanical problem solving and semantic knowledge: contributions to object usage in corticobasal degeneration.

To investigate the nature of the apraxia in corticobasal degeneration (CBD) five patients with CBD and five matched controls were compared on tests of: i) meaningless and symbolic gesture production, ii) a battery of semantic tasks based on 20 everyday items (involving naming and picture-picture matching according to semantic attributes, matching gestures-to-objects, object usage from name and with the real object) and iii) a novel tool test of mechanical problem solving. All five patients showed severe impairment in the production of meaningless and symbolic gestures from command, and by imitation, and were also impaired when using real objects. Deficits were not, however, restricted to action production: four were unable to match gestures to objects and all five showed impairment in the selection and usage of novel tools in the mechanical problem solving task. Surprising was the finding of an additional semantic knowledge breakdown in three cases, two of whom were markedly anomic. The apraxia in CBD is, therefore, multifactorial. There is profound breakdown in the organisation and co-ordination of motor programming. In addition, patients show central deficits in action knowledge and mechanical problem solving, which has been linked to parietal lobe pathology. General semantic memory may also be affected in CBD in some cases and this may then contribute to impaired object usage. This combination of more than one deficit relevant for object use may explain why CBD patients are far more disabled by their dyspraxia in everyday life than any other patient group.

Déjà vu: possible parahippocampal mechanisms.

Déjà vu experiences are common in normal subjects. In addition, they are established symptoms of temporal lobe seizures. The author argues that the phenomenon is the result of faulty and isolated activity of a recognition memory system that consists of the parahippocampal gyrus and its neocortical connections. This memory system is responsible for judgments of familiarity. The result is that a momentary perceived scene is given the characteristics of familiarity that normally accompany a conscious recollection. The normal functioning of other brain structures involved in memory retrieval--the prefrontal cortex and the hippocampus proper--leads to the perplexing phenomenological quality of déjà vu. The hypothesis accounts for many characteristics of déjà vu in healthy subjects and is well fitting with experimental findings in patients with epilepsy.
