A 58-year-old man is brought by his adult daughter for psychiatric evaluation after being terminated from his job as a bank manager 6 months ago due to increasingly inappropriate social behavior. His daughter reports that over the past 2 years, he has exhibited progressive personality changes including loss of social decorum, making sexually inappropriate comments to strangers, shoplifting small items without apparent need, and eating excessive amounts of sweets despite a prior history of healthy eating habits. He shows no concern about his job loss or the impact of his behavior on others. On examination, he demonstrates a flat, apathetic affect with occasional inappropriate jocularity. He is oriented to person, place, and time. His memory for recent events is relatively preserved — he can recall three objects after five minutes and accurately describes what he had for breakfast. However, he struggles significantly with verbal fluency tasks and demonstrates concrete thinking on proverb interpretation. His MoCA score is 22/30 with primary deficits in executive function and language subtests. Brain MRI has been ordered.
