Is something wrong with my brain? sleep apnea runs in father and sister. head feels like a brick at all times, intermittent tingling brain, memory loss, horrible concentration, brain fog, forcing myself to breathe sometimes. lightheaded 90% when i get in

No: Check reason for sleep apnea like adenoids, obesity. Otherwise see MD for anxiety or depression.

Maybe not!: There may not be anything wrong with your brain, but there could be other factors affecting the way your brain works! Sleep deprivation, drugs, sleep apnea, stress/anxiety, can all cause symptoms like you describe. If you correct the underlying problem, then your brain might work perfectly! I recommend seeing your doctor to try and determine what could be causing your symptoms!

Referral: Get a referral from your GP to a sleep lab, and get evaluated for sleep disturbances.
