Which statement about Alzheimer's disease is NOT true?

Alzheimer's disease is a progressive and irreversible neurodegenerative disorder primarily associated with aging. The statement indicating that it can be reversible and be cured is not true. Current medical understanding shows that Alzheimer's leads to the gradual degeneration of brain cells, resulting in cognitive decline, memory loss, and changes in behavior. While some interventions and medications can help manage symptoms or may slow the progression of the disease, there is no cure that can reverse the underlying damage caused by Alzheimer's.

In contrast, the other statements are accurate: Alzheimer's predominantly affects older adults, as the majority of cases occur in individuals aged 65 and older. Additionally, there are well-established risk factors for the disease, including advanced age and genetic predisposition, which play a significant role in its development. Memory loss is indeed a hallmark symptom of Alzheimer's, often prompting initial concerns that lead to diagnosis. Therefore, the assertion that Alzheimer's disease can be reversed is the only incorrect statement among the options provided.
