   2. Ageism is a form of age discrimination that can affect both the elderly and the young.
   3. Compared to young people, the brain of the elderly person generally needs less neural resources to accomplish a similar task.
   4. The brain volume decreases by about 2% per decade during adulthood to older age.
   5. Anatomical changes in the brain during aging are different depending on the brain region.

Answer 1

Option a is wrong as amyloid deposit can be viewed in old healthy individuals as a part of aging . It is seen in almost every old people. There is a risk for developing Alzheimer's with this association .

Option b is wrong as ageism is used by a age group to discriminate they from other age group. Let it be old or young it is used for stereotyping other age group in relation to their group

Option c is correct as the brain of older people required more number of neural region to accomplish an activity when compared to individual who is young. With aging the cognitive and physical ability of individual decline tremendously.

Option d is wrong as it has been noted that the brain Volume will decrease tremendously in individual when each decade pass. It is fixed to 2% in almost all upto old age and then about 5% after 70 year's of age

Option e is wrong as diffrent region of human brain undergoes diffrent change as the neural pathways leads . Example is the destruction of the dopamine pathway in parkinsonism.
