What is the first-line treatment for cognitive symptoms in Lewy body dementia?

• A. Memantine
• B. Atypical antipsychotics
• C. Donepezil or Rivastigmine
• D. Sertraline

Answer: (C)

In Lewy body dementia, cognitive symptoms such as memory loss, attention deficits, and difficulties with thinking and reasoning are prominent features of the disease. The first-line treatment for managing these cognitive symptoms is the use of cholinesterase inhibitors, specifically donepezil or rivastigmine. These medications work by increasing the levels of acetylcholine in the brain, a neurotransmitter that is often deficient in neurodegenerative disorders, thereby helping to improve cognitive function. They have been found to be effective in enhancing cognitive abilities and daily functioning in patients with Lewy body dementia, which is essential for maintaining quality of life. Other treatments, such as memantine, are used in certain types of dementia but are not preferred as first-line agents in Lewy body dementia, particularly for cognitive symptoms. Atypical antipsychotics may be utilized for managing behavioral symptoms or significant agitation but are not indicated specifically for cognitive improvement and carry risks of side effects. Sertraline, an antidepressant, is useful in treating mood disorders but does not directly address the cognitive deficits associated with Lewy body dementia. Thus, donepezil or rivastigmine is the most appropriate choice for targeting cognitive symptoms in this condition.
