What is Schizophrenia?

Schizophrenia is a severe mental health condition in which people interpret reality abnormally. It can impact speech, thinking, emotions, social interactions, everyday activities, and other areas of life. People have to tackle schizophrenia throughout their lives because it is not a treatable condition and needs continuous treatment for their whole life.

Its symptoms fairly occur when a person is in their late teens or early 30s. However, some cases are found in which the individuals begin to show symptoms of schizophrenia from childhood and it gets more significant as they get older. Whereas, in some cases, the symptoms may appear suddenly.

Schizophrenia may result in some combination of symptoms, such as hallucinations, delusions, extremely disordered thinking, and behaviour. All these impair daily functioning and can even result in disabling.

Schizophrenia is fairly an uncommon health condition with less than 1% of cases in the U. S. (According to the National Institute of Mental Health). Although the ratio of affected males and females with schizophrenia is almost equal, males have an onset.

On getting diagnosed early, its treatment can have a better impact and may get symptoms under control before serious complications develop.
