AIMS: The world is rapidly aging, and is facing an increase of late-elderly @entity303 @entity1 . It is important to investigate the characteristic features of late-elderly @entity303 in a super-aged country. METHODS: We examined 1554 @entity1 with @entity73 in Department of Neurology, Okayama University Hospital, Okayama, Japan, divided into three subgroups according to the age: young-elderly (age  <=64 years), middle-elderly (age 65-74 years) and late-elderly (age 75 years), and investigated the cognitive, affective and activities of daily living functions (ADL), especially in late-elderly @entity1 compared with young-elderly and middle-elderly @entity1 . RESULTS: Among 1554 @entity1 , @entity195 dominated at 62%, and age-dependently increased up to 69% in the late-elderly group. The total scores of four cognitive tests were significantly worse with aging for specific subscales of orientation, recall, @entity227 and so on. In contrast, total scores of the affective tests showed only an increase in the apathy scale in the late-elderly group. Each subgroup showed @entity308 in 63.2-55.2%, and apathy in 44.2-54.8%. Furthermore, instrumental ADL items significantly deteriorated in the late-elderly group, which statistically correlated with Mini-Mental State Examination score. CONCLUSIONS: These results show that the late-elderly group is characterized by significant @entity73 , increasing apathy, and instrumental ADL decrease. The @entity73 may be related to such affective and ADL declines. Geriatr Gerontol Int 2016; 16: 458-465.
