3. Shaking
There is not just one kind of dementia but rather many different forms. Dementia is NOT a normal part of aging but rather is the early or unusual deterioration in brain function owing to the death or destruction of neurons (brain cells).
This can lead to – among other things – shaking and difficulty with spatial awareness. What is happening here is that it is the motor cortex or premotor/supplementary motor cortices that have been affected. These are the parts of the brain responsible for movement and fine motor control.
If those areas are damaged, then the individual might start to show shaking, slow movement, slurred speech or similar symptoms. This can gradually become worse over time and may point to specific forms of dementia such as Huntington’s or Parkinson’s disease. The former is a genetic disorder that is ultimately fatal. Look into family history to eliminate this possibility.
