ACC from birth in 1962, was not discovered or diagnosed until a fall from a building necessitated an MRI in 2004, the doctor asked if I knew part of my brain was missing. I answered in the negative. It explains why I never had friends or social life, always awkward, bad at math and abstract thinking. Spent many years in the Army with no “ real” issues, no disciplinary actions, many awards and commendations.sadly there’s no cure for this thing and it just makes life lonely.
