These disorders include depression , stroke , an underactive thyroid gland (hypothyroidism ), and degenerative brain disorders such as Alzheimer disease . As people age, the number of nerve cells in the brain may decrease, although the number lost varies greatly from person to person, depending on the person’s health.
Also question is, how does old age affect the brain?
As we age our brains shrink in volume, particularly in the frontal cortex. As our vasculature ages and our blood pressure rises the possibility of stroke and ischaemia increases and our white matter develops lesions. Memory decline also occurs with ageing and brain activation becomes more bilateral for memory tasks.

As age increases from about 20 years there is a gradual and continuous decline in intelligence test score. A wide variety of measures of intellectual ability has been employed, and while the rate of decline is less with some tests than with others, the downward trend uniformly is found.
The nervous system is made up of the central nervous system and the peripheral nervous system: The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
Vitamins and minerals
Vitamins such as folate and B12 (types of ‘B complex’ vitamin) support the healthy function of the nervous system (the brain, the spinal cord and the nerves).
