Answer :
C. Degenerative refers to Alzheimer's disease.
- Alzheimer's disease is a neurodegenerative disorder, meaning it progressively leads to the loss of nerve cells and neurological function.
- It is primarily characterized by the gradual impairment of cognitive functions, which include memory, thinking, and reasoning.
- Over time, this leads to severe dementia, causing symptoms such as memory loss, confusion, difficulty in planning or executing tasks, and noticeable personality changes.
- Importantly, Alzheimer's disease is not associated with an immediate change in the level of consciousness.
