Which drug is primarily used for the treatment of dementia-related agitation?

Atypical antipsychotics are primarily used for the treatment of dementia-related agitation due to their effectiveness in managing behavioral symptoms associated with dementia. These medications, such as risperidone and quetiapine, can help alleviate agitation while often carrying a lower risk of extrapyramidal side effects compared to typical antipsychotics.

In individuals with dementia, behavioral disturbances like agitation can significantly impact the quality of life for both the patients and their caregivers. Atypical antipsychotics are preferred in these situations because they are generally better tolerated and have a more favorable side effect profile, which is crucial given the vulnerability of older adults and the potential for polypharmacy.

The other options listed may have their roles in managing mood disorders or other psychiatric conditions, but they are not the primary drugs of choice for addressing dementia-related agitation specifically. For instance, SSRIs are typically used for depression and anxiety rather than for acute agitation. Typical antipsychotics have more significant side effects and are less effective for this specific purpose, and while antidepressants may be used in some cases of depressive symptoms accompanying dementia, they do not directly target agitation.
