Schizophrenia is a brain disorder that affects the way a person behaves, thinks, and sees the world. People with schizophrenia often have an altered perception of reality. They may see or hear things that don’t exist, speak in strange or confusing ways, believe that others are trying to harm them, or feel like they’re being constantly watched. This can make it difficult to negotiate the activities of daily life, and people with schizophrenia may withdraw from the outside world or act out in confusion and fear.
The symptoms of schizophrenia fall into three categories: positive, negative, and cognitive.
Positive symptoms: “Positive” symptoms are psychotic behaviors not generally seen in healthy people. People with positive symptoms may “lose touch” with some aspects of reality. Symptoms include:
- Thought disorders (unusual or dysfunctional ways of thinking)
- Movement disorders (agitated body movements)
Negative symptoms: “Negative” symptoms are associated with disruptions to normal emotions and behaviors. Symptoms include:
- “Flat affect” (reduced expression of emotions via facial expression or voice tone)
- Reduced feelings of pleasure in everyday life
- Difficulty beginning and sustaining activities
- Reduced speaking
Cognitive symptoms: For some patients, the cognitive symptoms of schizophrenia are subtle, but for others, they are more severe and patients may notice changes in their memory or other aspects of thinking. Symptoms include:
- Poor “executive functioning” (the ability to understand information and use it to make decisions)
- Trouble focusing or paying attention
- Problems with “working memory” (the ability to use information immediately after learning it)
