Spatial navigation and episodic-memory tests in screening of dementia

To chci

Alzheimer's disease is from its onset associated with a loss of episodic memory and spatial navigation. In most cases it's prec eded with Mild Cognitive Impairment, which early diagnosis is an important objective for current medicine. To investigate more the specific im pairment in these cognitive domains, we develop new screening tests for the use in computer and/or in a unique real space navigation settin g called Blue Velvet Arena in the Hospital Na Homolce, Prague. The Hidden Goal Task evaluates two modes of spatial navigation: allocentric, u sing distal orientation cues, and egocentric, using current subject position. The Episodic-like Memory Test assesses non-verbal episodic-li ke memory con- sisting of information about ‘where' and ‘when' something happened and ‘what' happened. The Dissociated Reference Frames task i nvestigates navigation in two independent reference frames, room and rotating arena. We report some of preliminary results concerning the i mpairment of both Mild Cognitive Impairment and Alzheimer's disease subjects. … celý popis
