Dementia tends to alter behaviors, affects, and thought processes. Frontotemporal dementia, for example, causes disinhibition, abnormal behavior, and unstable moods, while Dementia with Lewy bodies impairs executive functioning and cognition in addition to causing hallucinations. Alzheimer's disease might cause psychological symptoms such as agitation, psychosis, and affect dysregulation. As a result, dementia might be misdiagnosed as a psychiatric disorder. Healthcare professionals should know that Alzheimer's patients tend to suffer from visual hallucinations, as opposed to those with psychiatric conditions, who typically suffer from auditory hallucinations.
