My father had shunt surgery last Wednesday for hydrosephlus. He is still in the hospital and not himself. He is having difficulty just dialing the phone and remembering family members. He is scheduled to go to a rehab. center for some OT and PT. He is definitley worse now then when he went in for the surgery. Is this normal? Could this be a stroke or the brain just getting used to the new hardware?

Our family (son, daugher-in-law and grandkids) went to see him today. He only remembered my wife's name without assistance. I asked the Dr. before the surgery what are the side-effects and/or complications and he said none.

Thanks.
