To prevent deterioration of cognitive functions
is important because it means to reduce the
number of people who develop or progress to dementia.
In the article “Daily Activities and
Cognitive Functions among the Elderly” of this
issue of the Taiwanese Journal of Psychiatry,
Tseng and colleagues are reporting that engagement
in either solitary or social activities was
found to have buffering effects of cognitive function,
that novel arts-related activities showed the
benefit of reducing the risk of cognitive function
declined by about 30%, and that exercising or engaging
in community recreational activities reduced
the risk by about 17%. They also found
that after controlling for the basic characteristics
of the subjects, multivariate analysis showed that
participation in diverse daily activities was significantly beneficial in reducing damage to the
cognitive function of elder individuals.
From the viewpoint of the community mental
health, the results of their study provide evidence
that promoting formal and informal daily
activities is beneficial for the elders. We have to
remember that one strategy may not be applicable
to all. Many factors contribute to the type of activity
people involve, health condition, particular the
severity of degenerative diseases (including visual
impairment), motivation, depression, lifestyle
characteristics, family support, and so on. Those
relevant issues also need to take into account in
the real world. Literature suggests that physical
activity is important for all, maintaining muscle
strength is of special importance, especially for
the aged population. A systematic review and meta-
analysis by Bridle and colleagues suggested
that participating in an exercise program can reduce
depressive symptoms by 20%.
