Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.
<h3>How brain changes in late adulthood?</h3>
The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.
The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.
