The purpose of this study was to clarify the relationship between the Functional Daily Activity Test scores and cognitive function in the elderly who regularly perform physical activity.

The subjects were 41 participants who participated in a once-a-week health exercise class and completed a Functional Daily Activity Test and a Cognitive Function Test in 2019. The average age of the subjects was 76.71±5.57 years. The data items collected were Physiological tests (Blood pressure), Anthropometry (Height, Weight, Body Mass Index: BMI), and Daily activity test (“Chair rise time", “10 m Obstacle walking speed", “10 m Zigzag Walking speed", “Test of hand working using Golf ball", “4 point touch time", “Grip strength").

Cognitive function measured were “Immediate recognition of word", “Date and time orientation", “Delay recognition of word", and “Figure recognition" using Touch panel-type Dementia Assessment Scale (TDAS).Furthermore, “Agility", “Effective utilization of brain", and “Energy of brain" were investigated using Advanced Trail Making Test (ATT).In TDAS and Functional Daily Activity, a statistically significant correlation was observed between “Chair rise time", “10 m Obstacle walking speed", “10 m Zigzag Walking speed" and “4 point touch time". In the item TDAS, the correct answer rate of “Figure recognition" was low, and the score of “10 m Zigzag Walking speed" was significantly low in the wrong answer group. In cognitive function, it gradually decreased from “Figure recognition", and it was shown that the decrease of “Figure recognition" affected 10 m Zigzag Walking speed among Functional daily activity. It was suggested that combining Functional daily activity such as “10 m Zigzag Walking speed" with TDAS could be a means to early detection of dementia.
