Compared with schizophrenia symptoms in adults, teens may be:
- Less likely to have delusions
- More likely to have visual hallucinations
Later signs and symptoms
As children with schizophrenia age, more typical signs and symptoms of the disorder begin to appear. Signs and symptoms may include:
- Delusions. These are false beliefs that are not based in reality. For example, you think that you’re being harmed or harassed; that certain gestures or comments are directed at you; that you have exceptional ability or fame; that another person is in love with you; or that a major catastrophe is about to occur. Delusions occur in most people with schizophrenia.
- Hallucinations. These usually involve seeing or hearing things that don’t exist. Yet for the person with schizophrenia, hallucinations have the full force and impact of a normal experience. Hallucinations can be in any of the senses, but hearing voices is the most common hallucination.
- Disorganized thinking. Disorganized thinking is inferred from disorganized speech. Effective communication can be impaired, and answers to questions may be partially or completely unrelated. Rarely, speech may include putting together meaningless words that can’t be understood, sometimes known as word salad.
- Extremely disorganized or abnormal motor behavior. This may show in several ways, from childlike silliness to unpredictable agitation. Behavior is not focused on a goal, which makes it hard to do tasks. Behavior can include resistance to instructions, inappropriate or bizarre posture, a complete lack of response, or useless and excessive movement.
- Negative symptoms. This refers to reduced or lack of ability to function normally. For example, the person may neglect personal hygiene or appear to lack emotion ― doesn’t make eye contact, doesn’t change facial expressions, speaks in a monotone, or doesn’t add hand or head movements that normally occur when speaking. Also, the person may have reduced ability to engage in activities, such as a loss of interest in everyday activities, social withdrawal or lack ability to experience pleasure.
