[Early recognition of tumors of the CNS]

434 patients with brain tumors from the years 1964 to 1980 have been analysed with the view to the length of anamnesis of the neurological and psychical symptoms as well as the false diagnoses (36.3%). Though 43.5% of the patients were admitted during the first two month of their complaints--this corresponds approximately to the share of the rapidly growing tumors (40%)--the number of the slowly growing ones is possibly raised by the improvement of early diagnosis. Distribution of sex and diagnostic practice have been compared with the literature, the problem of post-care is mentioned.
