[Non-delusional hypochondriac disorders in old age].

This review aims to present main concepts of hypochondria and 'hypochondriac mood' in old age. Attention is paid to historical and modern positions of old age hypochondria as a meta-syndromic pathology and as an independent mental disorder. Relationships of hypochondriac manifestations with affective variations and anxiety disorders, as well as somatic diseases, organic degenerative brain diseases and vascular disorders are discussed.
