DEAR DOCTOR K: My mother had a stroke that weakened one side of her body. But the bigger problem right now is her depression. Can that be treated, or is it caused by irreversible brain damage from the stroke?
DEAR READER: Strokes can cause significant problems. People can have difficulty moving (like your mother). They can have trouble speaking or understanding speech. They can have trouble thinking. Being suddenly hit with any or all of those losses would depress anyone -- including people who never suffered from depression before.
