Lewy Body dementia treatment

Lewy Body dementia treatment

• A. Adjunctive treatment for MDD
• B. Treatment-resistant MDD
• C. Clozapine, olanzapine, quetiapine, risperidone
• D. Quetiapine, fluoxetine/olanzapine combo

Answer: (D)

In Lewy body dementia, treating psychosis and mood symptoms requires choices that minimize worsening motor function and cognitive side effects. Quetiapine is favored for psychosis in this condition because it carries a relatively low risk of extrapyramidal symptoms and parkinsonism compared with other antipsychotics. Depression is common in Lewy body dementia, and when mood symptoms are present or psychotic features accompany depression, a combination approach can be helpful. Using quetiapine to address psychosis together with a fluoxetine/olanzapine regimen targets both domains—psychiatric symptoms and mood—without heavily compromising motor function. This dual approach aligns best with the management needs of Lewy body dementia among the options provided, whereas the other choices either focus only on mood disorders or rely on antipsychotics that are more likely to worsen motor symptoms in this population.
