schizophrenia

What exactly is schizophrenia and why a special day of observance? Here is an excerpt from NDTV:

“World Schizophrenia Day 2018 is observed on May 24. Schizophrenia is a mental condition which affects normal functioning of the brain. The condition interferes with a person’s ability to feel, act and think. Some schizophrenic patients recover completely and find an improvement in their symptoms. But others continue to suffer from schizophrenia for a prolonged period of time, wherein the distressing symptoms can last for years.
