Description

The diagnosis, sex ratio and age-distribution were investigated in 1, 301 patients, who visited the Neuro-otological Clinic and the Laboratory of Equilibrium Function in Kitasato University Hospital, Sagamihara City, in a 3 year period from January 1996 to December 1998. The percentage of people aged over 60 years old was 14.8% of the total population in Sagamihara city, but patients aged over 60 years old represented 37.4% of the total patients in Kitasato University Hosipital and 33.6% of the total patients in the Neuro-otological Clinic. The patients in the Neuro-otological Clinic were classified into 4 groups by diagnosis; peripheral vestibular disorders (19.1%), diseases of the CNS (8.3%), generalized disorders (3.9%), and others (68.8%). However, the percentage of peripheral vestibular disorders decreased from 19.1 to 11.7% and the percentage of CNS diseases increased from 8.3 to 16.9% in patients aged over 60 years old. Peripheral vestibular disorders included Meniere's disease, benign paroxismal positional vertigo, vestibular neuritis, sudden deafness and delayed hydrops in the 4th and 5th decades. The increase in the percentage of diseases of the CNS in elderly patients was accompanied by increases in cerebrovascular disease and vertebrobasilar insufficiency in the 6th decade.
