Erotomania in Alzheimer's Dementia: A Rare but Clinically Important Association.

Alzheimer's dementia is a common condition in old age psychiatry, typically presenting with memory impairment, confusion and behavioural disturbance. Erotomania is a rare psychiatric syndrome characterised by the fixed belief that another person, usually someone of higher social or economic status, is in love with the individual. The co-occurrence of erotomania in Alzheimer's dementia is highly unusual. We present a classical case of secondary erotomania in a patient with Alzheimer's dementia, highlighting the diagnostic challenges and management complexities associated with this presentation. This case emphasises the need for clinicians to recognise atypical delusional experiences in dementia.
