Hi, My Father Was Nexito Forte For Last 10 Years.

Hi, my father was nexito forte for last 10 years. Recently, he suffered acute mi followed by brain stroke. while undergoing treatment for mi and brain stroke, his nexito was stopped. however, in last 2-3 days he has become very aggressive, doesnt sleep and forgets every now and then and repeats same thing constantly. I have started giving him nexito for last 2 days, but there seems to be no improvement.
