Which patient with Alzheimer-type dementia is the best candidate for treatment with a second-generation antipsychotic?

The most suitable candidate for treatment with a second-generation antipsychotic among patients with Alzheimer-type dementia is a 75-year-old man with moderate Alzheimer's disease and hallucinations.

Second-generation antipsychotics are often considered for managing behavioral and psychological symptoms of dementia, particularly when patients experience symptoms such as agitation, aggression, or psychosis, which includes hallucinations. In cases where these symptoms are present, the risks associated with using antipsychotic medications can be justified due to the potential to significantly improve the patient's quality of life and reduce distress for both the patient and caregivers.

This patient is specifically presenting with hallucinations, indicating a need for symptomatic relief, making him the best candidate for this type of medication among those listed. Other patients in the options may have cognitive impairment or depression, which do not typically warrant the use of antipsychotics unless accompanied by severe behavioral disturbances. Additionally, the age and severity of dementia must be considered, but the presence of hallucinations in this case is a critical factor for treatment selection.
