In general, the term for a decrease in brain function, along with personality changes and memory loss is called dementia. There are at least 3 diseases that cause dementia. The most popularized one is Alzheimer's Disease. People with it might suffer depression in their 30's and then gradually forget things as they become older, and then they reach a point where they may come across as mean or vindictive when that is not like them.
Parkinson's Disease may have somewhat similar symptoms. They may shake a bit and start to forget things. They also may have some psychological changes.

The decrease in body energy requirements with age is primarily due to a decrease in muscle mass and a decline in metabolism. As we age, we tend to become less physically active, which reduces the amount of energy our body needs. Additionally, hormonal changes and a decrease in organ function further contribute to lower energy needs as we get older.

Maximum heart rate decreases with age due to a natural decline in the efficiency and function of the heart muscle, as well as changes in the body's ability to respond to physical stress and exercise. This decrease is a normal part of the aging process and is influenced by factors such as decreased cardiac output and changes in the autonomic nervous system.
Mildly involutional changes typically refer to age-related changes that occur as part of the natural aging process. These changes may include alterations in tissue structure or function, such as a decrease in collagen production or changes in skin elasticity. In the context of medical imaging, it may also refer to subtle changes seen on scans as a result of aging.
