The wife reports that he has been acting strangely for the past 2 months, becoming easily irritated and frequently criticizing her and their children. Initially, the changes were subtle, but now arguments occur every other day. The husband doesn’t acknowledge any issues, and you observe that he struggles to initiate conversations and often pauses mid-sentence. There is no significant family history, and the husband is not on any regular medications.
