can be increased. At least in elderly folks.
A very simple way for older folks to improve their IQ and brain power is to make sure their senses are working as best they can be. Quite of bit of research over the last few years has shown that when sensory perception is abnormal in elderly people, brain performance suffers and IQ drops-
and a new study out of Case Western Reserve confirms this principle.
In other words, if hearing is poor, perhaps you need to have a hearing aid placed. If vision is impaired, a good pair of glasses may be needeed, or a visit the eye doctor to fix any cataracts or other eye disease that may be present. All of these simple measures can actually improve brain performance and IQ.
