The treatment for Alzheimer's disease commonly includes which class of medications?

• A. Cholinesterase inhibitors
• B. Dopamine agonists
• C. SSRIs
• D. Opioids

Answer: (A)

Alzheimer's disease involves a loss of cholinergic neurons and reduced acetylcholine in brain areas essential for memory. Medications that inhibit acetylcholinesterase, the enzyme that breaks down acetylcholine, help keep acetylcholine available longer in the brain. This boosts cholinergic signaling and can provide modest improvements in memory and daily function for many people, especially in the mild to moderate stages. Drugs in this class include donepezil, rivastigmine, and galantamine. They are used as symptomatic treatment rather than disease-modifying cures. Common side effects are gastrointestinal upset and, in some cases, slowed heart rate or fainting, so monitoring is important, particularly for individuals with heart conditions. Other drug classes like dopamine agonists, SSRIs, or opioids target different conditions and do not address the cholinergic deficit at the heart of Alzheimer's cognitive symptoms.
