question: Hello Doctor, My father who is 60 years old recently underwent surgery for CSDH(Chronic Subdural Hematoma) both burrhole and craniotomy performed.  After surgery he is able to walk and do his own works perfectly. But he has some behavioral changes like opposing medication. He feels that somebody going to hurt him with medication. To control this we went to psychiatrist, he gave us zolfresh 10mg and some other medicines.Prior to these medicines we used to give Gabapentine 300mg, Eptoin 100mg for neuro. When we started the medication upto 10 days he is fine but after that he became fully drowsy gradually, after one month he is not able sit also. Last week we took scan neuro doctors saying perfectly alright. Both sodium and potasium levels are normal. But still in fully drowsy state. Please suggest us what to do.Thanks,Grani
