Dementia is a condition that is frequently associated with ageing. However, many fail to recognise that dementia is a treatable condition if detected early. This case report illustrates a 64-year-old man who was initially presented in a primary health care (PHC) centre in Kuala Lumpur Malaysia, with gradual changes in his behaviour. Initial assessment concluded that he suffered from depression and he was treated accordingly. However, over time his condition deteriorated and the diagnosis was re-evaluated from depression to dementia when he developed poor cognitive and memory function. The patient defaulted on his follow-up appointments due to poor understanding of the illness and poor family support.
