Intelligence can link to health and aging

“There are a lot of hypotheses on what this link is, but no model to link them all together,” said
Geary’s insight came as he was working on a way to better understand gender-specific vulnerabilities related to language and spatial abilities with certain prenatal and other stressors, which may also involve mitochondrial functioning. Mitochondria produce ATP, or cellular energy. They also respond to their environment, so Geary said habits such as regular exercise and a diet with fruits and vegetables, can promote healthy mitochondria.
“These systems are being used over and over again, and eventually their heavy use results in gradual decline,” Geary said. “Knowing this, we can help explain the parallel changes in cognition and health associated with aging. Also with good mitochondrial function, the aging processes will occur much more slowly. Mitochondria have been relatively overlooked in the past, but are now considered to relate to psychiatric health and neurological diseases.”
Geary said chronic stress can also damage mitochondria that can affect the whole body -- such as the brain and the heart -- simultaneously.
