There are two types of brain tissue: grey and white matter.

Structural and functional changes take place with aging in the grey and white matter of the brain.

These include:

  • Grey matter volume begins to decrease after age 20. This is caused by the death of neurons. The amount of atrophy or shriveling is most prominent in the prefrontal cortex, temporal lobes, and the hippocampus. Decreases in brain volume and accumulation of beta-amyloid are seen in Alzheimer’s dementia.
  • White matter volume decreases are much greater than grey matter volume decreases with increasing age and are associated with deficits in problem solving, language, memory and visuospatial abilities. What this means in plain English is your brain is shriveling up, and your brain processing speed slows down. The brain has “pauses” and feels like it is in a dense fog.

Want to help yourself, feed the brain and bring the grey and white matter of your brain back to life?

Here are some activities that are associated with high cognitive function in older adults and the prevention and or delaying of age-related cognitive decline:

  • Puzzles, reading, using the computer
  • Playing musical instruments
  • Careers that involve problem solving
  • Aerobic exercise
  • Gardening
  • Travel
  • Socializing with friends and family
