In the year 2015, Germany doctors reported on the extraordinary case of a woman who suffered from ‘Multiple Personality Disorder’. The Multiple Personality Disorder is today known as the ‘Dissociative Identity Disorder’. An exhibition of dissociated personalities characterises multiple Personality Disorder. Similarly, the women exhibited differential personalities some of those reflected blind. The doctors made the use of EEG’s and ascertained that the brain’s activity associated with sight was absent. A blind was controlling the woman’s body with her eyes open. In place of this, when the control was assumed back by a sighted, her brain functioned normally.

This entire phenomenon resembled blinding powers of extreme forms of dissociations. This condition is when the person gives rise to multiple personalities. Operationally parted centres of consciousness often illustrate the multiple personality presence. Each centre has its personal life.

The modern neuroimaging techniques now confirm that the ‘Dissociative Identity Disorders’ is real. In the year 2014, doctors worked out a research study on both the DID patients and actors exhibiting DID symptoms. The study involved scanning the brains of both the DID patients and actors. Scan results highlighted the differences between the two. The scanning difference illustrated the presence of identifiable neural activity fingerprint.

If we look back at the history of the multiple personality disorder, it dates back to the early period of the nineteenth century. There was a flurry of multiple personality disorder cases in the period from 1880 to 1920. Later, similar cases were re-witnessed back in the period from 1960 to 1990.
