Dr. Pulkit Sharma, clinical psychologist in VIMHANS, says that split personality disorder is characterised by huge memory loss. A suffering person is even unable to recollect his/her activities of previous day. The reason for huge memory loss is that that the suffering person has multiple personalities. At a particular time, he/ she portrays a single personality and its various characteristics. All the personalities of a person have completely different set of emotional, mental, social and behavioural pattern. One personality of the suffering person does not know that the others exist too. He/she experiences discontinuity of time and finds his/her inability to recall any past event or thought making the person baffled. An individual with multiple personalities needs to go through intense psychotherapy.
