Answer:
Over half the neurons of the brain are in a structure that constitutes only 10 percent of the brain’s total mass this structure is the cerebellum.
Explanation:
More than 50% of the brain's overall neurons are found in the cerebellum, although making up just about 10% of the brain's entire volume. The cerebellum has traditionally been thought to be a motor structure since cerebellar injury affects the position and motor function, as well as the bulk of the cerebellum's outputs, go to the motor neurons. The cerebellum does not originate motor orders; instead, it changes descending paths' control signals to improve the adaptability and precision of movements. Moreover, the cerebellum is responsible for many functions in the body including movements, vision, and balance, etc.

Answer:
Neurodegeneration
Explanation:
The term neurodegeneration refers to a group of disorders which are characterized by a progressive waste of function or structure of neurons, that in worst cases can include death of neaurons.
Many neurodegenerative disorders such as Parkinson's disease,– including amyotrophic lateral sclerosis, Huntington's disease and Alzheimer's disease can occur due to neurodegeneration.
Neurodegeneration can manifest itself in various forms such as lack of physical and intellectual abilities like inability to use muscles or memory loss. These disorders cannot be completely cured and ultimately lead to the death of neurons.
As mentioned in the question, the person suffers from progressive loss of intellectual and physical abilities that has occurred over the course of a long period of time. Therefore, it is most probable that he is having some neurodegenerative disorder.
