Which statement about Alzheimer's disease treatment is true?

• A. There is a cure that halts disease progression.
• B. Memory loss cannot be treated and therapy is never used.
• C. Some drugs tend to enhance memory and reduce anxiety and depression.
• D. Surgery can reverse dementia.

Answer: (C)

Treatments for Alzheimer's disease aim to relieve symptoms rather than cure the condition. There isn’t any therapy that stops or reverses its progression. However, certain medications can provide modest improvements in memory and thinking for some individuals, and they can help with behavioral or mood symptoms such as anxiety or depression. The main drug types are cholinesterase inhibitors (like donepezil, rivastigmine, and galantamine) and memantine; these may slow decline and improve cognitive or daily functioning for a time, but they do not halt the disease and can have side effects. Surgery does not reverse dementia, and memory loss isn’t completely eliminable by therapy alone. So the statement that some drugs tend to enhance memory and reduce anxiety and depression accurately reflects current treatment.
