Aerobic exercise improves cognition in old age

Mild cognitive impairment (MCI) refers to the slightly decreased cognitive abilities in individuals of 65 years of age and over. Such people may experience minor cognitive decline in memory or reasoning, but not to an extent where it interferes significantly with daily activities.

Studies report that anywhere between 5-20 percent of the older population have MCI.

MCI often leads to Alzheimer's disease (AD). Some studies have shown that 80 percent of patients with MCI have developed AD after 6 years.

Previous research has suggested exercise training may increase the volume of some brain areas and improve memory.

Now, new research confirms it may not only increase brain size, but could also improve cognition in patients with MCI.
