Amanda Bynes has responded "quickly and dramatically" to treatment for the apparent mental break that saw her hospitalized on a 5150 involuntary hold last month.
Sources say Bynes's doctors have given her a cocktail of psychiatric drugs to treat apparent symptoms of schizophrenia and that the troubled actress has stopped talking to herself and insulting people. Doctors are cautiously optimistic -- the full effects of these complex combinations of medications can take seven to 10 days to fully kick in -- but the shift in her behavior has reportedly been remarkable.
