Implizite Gedächtnisfunktionen bei transitorischer globaler Amnesie
Abstract
dc:descriptionTransient global amnesia, TGA, is an impairment of memory of temporary nature that is characterized by an anterograde amnesia for declarative contents. The syndrome is benign and patients recover within 24 hours without relevant remaining deficits. The main aim of this dissertation was the assessment of implicit memory during the attack. In 10 patients a neuropsychological protocol was administered during the attack and one week later and the results were compared to a group of control subjects matched to the patients in sex, age, intelligence, education and handedness. Statistical analysis was performed using a repeated measures ANOVA. At first, general cognitive functions were assessed, i.e. visuoconstructive abilities, semantic memory and intelligence to exclude an unspecific influence on the test results. Patients were not impaired with respect to semantic and phonological fluency, yet they had problems generating words under alternating conditions. The extent of anterograde amnesia became apparent in two verbal and one non-verbal test, a retrograde amnesia could not be detected. Implicit memory was assessed by a verbal and a non-verbal perceptual priming task and a procedural task. Patients were able to, firstly, acquire implicit material during TGA and, secondly, to retrieve the material one week later.
