Which of the three would most likely be causing degeneration of my cognitive abilities? Car wreck in 2003, bad bad bad, hit head very hard on windshield, the other injuries in said wreck aren't what I'm worried about. Well, let me say several car wrecks; in the others I didn't get a direct hit to the forehead but certainly got jostled.

Drug overdose in 2007. A plethora of drugs including Fentenyl, cocaine, and alcohol. Boyfriend found me unresponsive on his couch. When I finally awoke in the hospital I couldn't hear a thing! Hearing eventually came back, but, I don't know what is happening to me now.Sure there were some cognitive issues for a bit, but now...short and long term memory loss, confusion, sometimes can't even form a complete sentence because I can't recall words! I have an impressive vocabulary, well, did.

Any thoughts, suggestions....anything would be appreciated. Thanks
