3. Alien Hand Syndrome
Also known as Dr. Strangelove Syndrome, it’s a rare mental disorder by which the sufferer loses total control of a hand or any limb. It has no cure, and sufferers usually have to use another hand to control the uncontrolled one. It may happen after a split-brain operation, an aneurysm, a brain tumor, or a stroke.
- Reports of a hand or limb which suddenly has a mind of its own, moves as it pleases, and even becomes violent toward the patient by trying to grab their neck, scratch them, or take off their clothes.
- Patients feel alienated toward their hand or limb to the degree that it could drive them to hurt themselves.
4. Dissociative Identity Disorder
It used to be called Multiple Personality Disorder, and, as its name suggests, it is a mental illness presented in people who exhibit more than one personality, usually between 2 and 3 different identities. This disorder is one of the most famous on the list since it has been portrayed several times on screen, and the truth behind this illness that affects between 0.01% and 1% of the general population is disturbing. They commonly end up in mental institutions.
- People with DID appear to have more than one identity. They have different names, personalities, and genders.
- There is a random switch from one identity to the other with no warning, after hours or years.
- There are episodes of amnesia.
- Patients don’t realize what is going on with their condition, which makes it hard for them to live a normal life and causes struggles in their family, social, and professional life
