RESULTS Following an extensive review of selected studies from the 201 articles , the studies indicate that each of the psychotropic medications review ed impact alpha , beta , delta and theta waves independently and differently from each other .
Additionally , certain medications , particularly haloperidol and valproic acid , have dissimilar results exemplified in all waveforms .
OBJECTIVES It is known that psychotropic medications have an impact on the readings found in Electroencephalogram ( EEG ) .
In the field of psychiatry , there are several psychotropics utilized by clinicians .
This review seeks to investigate all the available data for psychotropic drugs and their impact on EEG changes .
Changes in EEG order in neuroleptically treated normal volunteers during a voluntary movement task
Summary 15 normal volunteers were treated over three weeks with haloperidol ( HAL ) and in the third week additionally with biperidene ( BIP ) . The order of the EEG spectra at different topographical locations and in different frequency b and s during a movement task was analyzed using uncertainty analysis ( UA ) , a multivariate analysis technique based on informationtheoretical methods . Different patterns of drug-induced changes were found . HAL decreases the theta and alpha b and order at the fronto- central lateral areas but increases it at the fronto- central midline in the theta b and and at the parietal areas in the alpha b and . With the exception of the fronto- central midline locations , BIP more or less counterbalances the effect of HAL . Volunteers felt unwell and had motor disturbances during HAL and felt well again during HAL + BIP .  Reaction time values were increased during HAL and normalized during HAL + BIP
