Do the meds my 20 yo son effect his cognition or is it the disease itse.lf?
It depends on what meds he's on, but both meds and your son's schizophrenia can effect his cognition. What kind of schizophrenia does he have? I ask this because there are different sub-types. Also can you define cognition a little more- What cognitive abilities are you worried about?
Best of luck.
