Which class of medications is typically used for mild to moderate dementia?

• A. Acetylcholinesterase Inhibitors
• B. Antidepressants
• C. Antipsychotics
• D. NMDA Receptor Antagonists

Answer: (D)

For mild to moderate dementia, the main treatment approach is to support the cholinergic system in the brain. Acetylcholinesterase inhibitors do this by increasing acetylcholine levels, which can help with memory and thinking in many people with Alzheimer’s disease during these earlier stages. Common examples include donepezil, rivastigmine, and galantamine. These medications are started when symptoms are mild to moderate because the brain’s acetylcholine is diminished early on, and boosting it can offer modest cognitive benefits and functional support. In contrast, NMDA receptor antagonists, such as memantine, regulate glutamate activity and are typically reserved for moderate to severe dementia or when acetylcholinesterase inhibitors aren’t enough. They’re not usually the first choice for mild cases. Antidepressants and antipsychotics can be used to manage mood or behavioral symptoms that may accompany dementia, but they don’t treat the core cognitive impairment in the mild to moderate stage and aren’t the primary agents for this aspect of the disease.
