There are several types of schizophrenia, so signs and symptoms vary. In general, schizophrenia symptoms include:
- Beliefs not based on reality (delusions), such as the belief that there’s a conspiracy against you
- Seeing or hearing things that don’t exist (hallucinations), especially voices
- Incoherent speech
- Neglect of personal hygiene
- Lack of emotions
- Emotions inappropriate to the situation
- Angry outbursts
- Catatonic behavior
- A persistent feeling of being watched
- Trouble functioning at school and work
- Social isolation
- Clumsy, uncoordinated movements
Schizophrenia ranges from mild to severe. Some people may be able to function well in daily life, while others need specialized, intensive care. In some cases, schizophrenia symptoms seem to appear suddenly. Other times, schizophrenia symptoms seem to develop gradually over months, and they may not be noticeable at first.
Over time, it becomes difficult to function in daily life. You may not be able to go to work or school. You may have troubled relationships, partly because of difficulty reading social cues or others’ emotions. You may lose interest in activities you once enjoyed. You may be distressed or agitated or fall into a trance-like state, becoming unresponsive to others.
In addition to the general schizophrenia symptoms, symptoms are often categorized in three ways to help with diagnosis and treatment:
Negative signs and symptoms
Negative signs and symptoms represent a loss or decrease in emotions or behavioral abilities. They may include:
- Loss of interest in everyday activities
- Appearing to lack emotion
- Reduced ability to plan or carry out activities
- Neglecting hygiene
- Social withdrawal
- Loss of motivation
Positive signs and symptoms
Positive signs and symptoms are unusual thoughts and perceptions that often involve a loss of contact with reality. These symptoms may come and go. They may include:
- Hallucinations, or sensing things that aren’t real. In schizophrenia, hearing voices is a common hallucination. These voices may seem to give you instructions on how to act, and they sometimes may include harming others.
- Delusions, or beliefs that have no basis in reality. For example, you may believe that the television is directing your behavior or that outside forces are controlling your thoughts.
- Thought disorders, or difficulty speaking and organizing thoughts, such as stopping in midsentence or jumbling together meaningless words, sometimes known as “word salad.”
- Movement disorders, such as repeating movements, clumsiness or involuntary movements.
Cognitive signs and symptoms
Cognitive symptoms involve problems with memory and attention. These symptoms may be the most disabling in schizophrenia because they interfere with the ability to perform routine daily tasks. They include:
- Problems making sense of information
- Difficulty paying attention
- Memory problems
When to see a doctor
People with schizophrenia often lack awareness that their difficulties stem from a mental illness that requires medical attention. So it often falls to family or friends to get them help.
