Question

Quizplus · Accepted Answer

Normal age-related cell death in the brain, also known as neuronal apoptosis, is a natural process that occurs in all individuals as they age. However, it does not necessarily lead to the loss of ability to engage in everyday activities.

None of the other options are correct. Alzheimer's disease is a complex neurological disorder with multiple risk factors, and not solely caused by age-related cell death. Cerebrovascular dementia is caused by impaired blood flow to the brain due to stroke, and not related to age-related cell death. Parkinson's disease is associated with the loss of dopamine-producing neurons in a specific region of the brain, and again, is not solely caused by age-related cell death.
