  • Hey there and welcome to Life Noggin.

  • The human brain is an incredibly complex organ, it makes you who you are!

  • But sometimes, according to psychologists, your brain can take that sense of self -- your

  • personality -- into pieces -- making you seem like you're more than one person.

  • This is called Dissociative Identity Disorder, it used to be called Multiple Personality

  • Disorder, but not anymore.

  • Two out of every 100 people experience a feeling of having more than one personality, at least

  • once in their lives; usually it's not serious.

  • Very few people show up into a psychologist's offices because multiple personalities (called

  • alters) are causing problems.

  • To get this disorder you'd have to have "two or more" identities that can take control

  • of your behavior, and they have to have different memories and feelings of self.

  • There are only a few people who've actually been documented with this psychological condition,

  • but you've probably heard of it thanks to movies and television!

  • In the movies, character's multiple personalities can talk to each other, but in real life,

  • only the single personality can talk.

  • Think of D.I.D. as multiple people trying to share one single phone.

  • Only one can talk at a time, and when one has the phone, the others can't hear anything.

  • This is why psychologists often find people with D.I.D. have gaps in their memory, when

  • the alters are in charge of the body, they don't remember anything!

  • No one really knows exactly why someone's personality would fragment like this.

  • But it's a hot debate in the mental health field!

  • The manual for psychologists, called the DSM, says it could be caused by trauma during childhood,

  • but some psychiatrists think D.I.D. doesn't exist at all.

  • Instead, they think it's a product of the stories we read and see.

  • In the 1950s, a best-selling book had a character with multiple personalities, and psychologists

  • saw many patients believing they had them too.

  • It happens again and again, with the last personality fad popping up in the 1990s as

  • Hollywood released dozens of movies with dissociative identities in them.

  • On the other hand, studies have scanned the brains of patients, and measured their skin's

  • ability to conduct electricity -- and found that they might change depending on the alter in control.

  • So, the jury is still out.

  • The reason psychologists call them alters and not personalities, is because the patients

  • don't really have two or three or five separate personalities inside one head, instead

  • it's a single personality broken into pieces, like fragments of a dish that's been broken.

  • Each alter has a part of the single personality.

  • Meaning each alter might have a different mood, age, level of education, name or even

  • gender. The alters are having trouble working together to make a whole person, but each alone has their own experiences, memories, and mannerisms.

  • Picture a man named Jared who has Dissociative Identity Disorder.

  • Jared could have one alter that is a woman who needs glasses, a second who is an old

  • British man, and a third who is a toddler that cries all the time!

  • Jared might experience all of these fragments in his head at the same time, or not, he could

  • hear their voices or not, he might even have amnesia if one of the other alters took over!

  • Unfortunately for patients with D.I.D., just like a broken bowl, there's always one big piece.

  • The biggest personality, the main person, would probably feel very depressed and sad,

  • would have memory loss from when the fragments took over, and could carry a lot of guilt

  • and stress because of it.

  • In the end, psychologists will keep an eye out for patients who have more than one personality

  • (one woman claimed to have 162), but for most of us, we'll have to be satisfied with the

  • one we've got.

  • This video was written by our good friend Trace Dominguez.

  • He just made a series on Fake News, which you should totally check out.

  • As always, I'm Blocko and this has been Life Noggin.

  • Don't forget to keep on thinking!
