Multiple Personality Disorder
MPD is a disorder that makes an individual have two or more personalities with different memories and behavior. This affects teenagers because I chose MPD because it always interested me.
The first time I heard about it was in a book where the main character had the disorder, and I wondered how it worked. Believing of this disorder was difficult until I dug deep into it. I learnt that people hurt their families, ruined their lives or created new lives out of them and it made me think a lot about the mind and how this could affect us.
