Hi, I m here for my dad. He recently(july2013) had craniotomy for subdura hematoma, part of his right skull is in his stomach for harvesting. Thankfully he woke from sedation around two weeks after surgery. Limb movement improved with his routine physiotherapy but only his left hand which has improved has become weaker and weaker recently. Could it be sunken scalp syndrome ? Also, he tends to forget what is happening around him In just few minutes. But, he recognises people and voice well. Is this post surgery effect?
