my son also had a severe head injury 8 yrs ago with bleeding in brain and skull fracture he was in a coma for 1 week . He was put on zoloft last year for what dco thought was ocd. well he recently had a grand mal seizure after doc increased his dosage. I honestly beleive the zoloft triggered the seizure neurologist toke him off it he is now on seizure med. he did very well for 8 yrs and now seizures you never know what is going to happen I thought this accident was all behind him. Looks like his problems are just starting they found a cyst now also we see a surgeon next week.
