An abrupt onset of psychosis in an older or elderly individual with no prior history of psychiatric disorders should trigger a comprehensive evaluation for neurological causes of psychiatric symptoms. This study examines and compares the clinical features of new-onset psychotic symptoms in two patients, one with an acute basal ganglia hemorrhagic stroke and the other with an acute mid-brain ischemic stroke. Delusions and hallucinations resulting from basal ganglia lesions are believed to arise from frontal lobe dysfunction, leading to a disruption in reality checking pathways in the brain. On the other hand, visual hallucinations stemming from mid-brain lesions are thought to occur due to the dysregulation of inhibitory control in the ponto-geniculate-occipital system. Psychotic symptoms following a stroke exhibit diverse clinical characteristics that are influenced by the stroke's location in the brain. The use of antipsychotic medications may offer relief from symptoms.
