I wonder if he was on SSRI’s? A coworker years ago who was on Paxil told me of a totally unprovoked violent episode he had with his wife. He asked her if she’d taken the car into the shop, she said she hadn’t. Suddenly he’d flipped the kitchen table over in a fit of rage. Which was very uncharacteristic. If you look on the bottle, it will warn of violent unprovoked episodes...
--SSRIs Rx'd past or present?
--Other drugs, including opioids, marijuana, and/or meth and/or alcohol (and some others)?
--Low levels of vitamin D?
--Possibly even potential brain tumors or head injuries?
