Difference Between Dissociative Identity Disorder (DID) and Schizophrenia
Schizophrenia and DID are often misunderstood and thought to be similar kinds of mental illness, but they are actually very different.
Schizophrenia usually happens when a mother is exposed to some viruses or malnutrition at the time of 1st or 2nd trimester of pregnancy. It also involves alteration of brain activity that includes the neurotransmitters dopamine and glutamate.
Dissociative disorders (DID), usually happens as a result of any traumatic event. The traumatic event could be physical abuse, any aggressive combat mission, reminiscence of which the brain attempts to control. The illness becomes worse when an individual is under tremendous stress.
What is Dissociative Identity Disorder (DID)?
DID (previously known as multiple personality disorder) is a complicated psychological condition that is triggered by many reasons like severe trauma during early childhood (for e.g. extreme physical abuse or extreme emotional abuse). The disorder can last for years, become chronic and in some cases, last lifelong. Treatment involves supportive care, counselling and talk therapy. Frequency is ~2% of people.
What is Schizophrenia?
Schizophrenia is a mental disorder characterised by thoughts or experiences which are nowhere close to real world. It includes erratic speech or behaviour and reduced participation in daily activities. Issues associated with concentration and memory can also be seen. What triggers this disorder is not known, however, scientists claim that a combination of genetics, external environment and altered brain mechanism and structure could be responsible. About 1% of all people develop schizophrenia.
