What is the treatment approach for dementia?

• A. Cholinesterase inhibitors cure dementia
• B. Antipsychotics prevent progression of dementia
• C. Vitamin therapy reverses dementia
• D. No drugs clinically proven to prevent or cure; off-label use of acetylcholinesterase inhibitors, antidepressants, anti-anxiety, and antipsychotics

Answer: (D)

No drug has been proven to prevent or cure dementia; the treatment approach focuses on managing symptoms and supporting daily function. Cholinesterase inhibitors (used to help cognition in some forms of dementia) and memantine can provide modest, temporary improvements for some patients, but they do not halt or reverse the disease course. Because no cure exists, many medications are used off-label to address related problems rather than to stop progression: acetylcholinesterase inhibitors in various dementias, antidepressants for depressive symptoms, anti-anxiety medications for anxious or agitated states, and antipsychotics for severe behavioral disturbances. These are aimed at improving quality of life and reducing distress, not curing the dementia.
