Summary

The memory in the human brain is not a unified system. Widely accepted classification discerns short-term working memory, long-term conscious declarative memory (semantic and episodic) and several types of non-conscious memories: procedural (habit), priming, pavlovian conditioning and emotional conditioning. The amnesia is a disturbance of declarative memory. The anatomic classification of amnesia differentiates the hippocampal, and diencephalic amnesias, amnesia in disturbance of the basal telencephalon and damage of some types of brain white matter systems. Minimal cognitive impairment and evolution of Alzhei-mer’s disease are most obvious causes of evolving recent episodic memory impairment amnesia encountering the family doctor.

Key words:
short-term (working) memory, declarative, semantic, episodic, amnesia.
