[Neuropsychology of Korsakoff's syndrome].

The main manifestation of Korsakoff's syndrome is a disproportionate impairment in memory in comparison to other cognitive functions. Most prominent is anterograde amnesia for both verbal and nonverbal information. The marked sensitivity to interference is the main characteristic of memory impairment of these patients. Retrograde amnesia is also a typical feature of this disorder. Memory for autobiographical information as well as knowledge of public events and facts are affected and they have a temporal gradient. Confabulations may also occur but they are not specific to Korsakoff's syndrome. Together with the disproportionate deficits in memory that define this disorder, different grades of involvement of other cognitive disorders are observed. The aim of this paper is to review the most important neuropsychological features of Korsakoff's syndrome and to discuss the hypotheses on it.

[Neurophysiologic bases and neuropsychological approach to the study of infantile hyperactivity].

Hyperactivity is a common important group of childhood behaviour problems with great influence on the personal, familiar and social sphere, a better knowledge of which is important. Up to now several explanatory hypotheses have been pointed out. From some time ago, the physiopathological roots of this clinical description has been studied in depth. The authors make a review of the neurophysiological and neuropsychological bases of hyperactivity in children.

[Memory disorders and attention deficit modulation in child hyperactivity].

The infantile hyperactivity is a disorder of great significance due to its remarkable after-effects on the family, the school and the individual. According to strict diagnostic criteria the study of the memory in these children who present a well defined disorder of the attention, has been planned. The data show that the mnemonic capacity is primarily kept. However the nuclear problem is an attention deficit.

[Brain mapping studies in dyslexia].

Brain EEG mapping has been recorded during three different conditions, rest closed eyes, rest open eyes, and reading task, in a group of 22 dyslexic children, age mean 9.3 years, range 8-11, and control group of normal readers of the same age. All the subjects were right-handed, and laterality was assessed through the Edinburgh test. The individual maps in dyslexic and controls were averaged, and mean maps of both groups were obtained for a very different experimental condition. Rest closed eyes maps of dyslexics and controls disclose a powerful and symmetric alpha over occipital areas, with higher energy peak at 8.5-9.5 Hz., without significant differences in both groups. Brain maps centered in the fast beta band, 18-25 Hz., disclose significant differences in control group versus dyslexics, with more power in control group over all areas. Our findings suggest less adequate brain activation in dyslexics during reading tasks.
