What are the key symptoms of schizophrenia?

The key symptoms of schizophrenia include delusions, hallucinations, disorganized speech and behaviour, and negative symptoms.

Schizophrenia is a severe mental disorder that affects how a person thinks, feels, and behaves. The symptoms of schizophrenia can be divided into two categories: positive symptoms and negative symptoms. Positive symptoms include delusions, hallucinations, disorganized speech and behaviour, and abnormal movements. Delusions are false beliefs that are not based on reality, while hallucinations are sensory experiences that are not based on reality, such as hearing voices or seeing things that are not there. Disorganized speech and behaviour can include speaking incoherently or acting in a bizarre way. Abnormal movements can include repetitive movements or catatonia.

Negative symptoms are characterized by a loss of normal function. These symptoms can include a lack of motivation, social withdrawal, a lack of emotional expression, and a decrease in the ability to experience pleasure. Negative symptoms can be more difficult to treat than positive symptoms and can have a significant impact on a person's ability to function in daily life.

It is important to note that not everyone with schizophrenia will experience all of these symptoms, and the severity of symptoms can vary from person to person. Early intervention and treatment can help manage symptoms and improve a person's quality of life.
