Contrary to public perception, schizophrenia is not split personality or multiple personality. The vast majority of people with schizophrenia are not violent and do not pose a danger to others. Schizophrenia is not caused by childhood experiences, poor parenting or lack of willpower, nor are the symptoms identical for each person.
What Causes Schizophrenia?
The cause of schizophrenia is still unclear. Some theories about the cause of this disease include: genetics (heredity), biology (abnormalities in the brain’s chemistry or structure); and/or possible viral infections and immune disorders.
Scientists recognize that the disorder tends to run in families and that a person inherits a tendency to develop the disease. Similar to some other genetically-related illnesses, schizophrenia may appear when the body undergoes hormonal and physical changes (like those that occur during puberty in the teen and young adult years) or after dealing with highly stressful situations.
Chemistry – Scientists believe that people with schizophrenia have an imbalance of the brain chemicals or neurotransmitters: dopamine, glutamate and serotonin. These neurotransmitters allow nerve cells in the brain to send messages to each other. The imbalance of these chemicals affects the way a person’s brain reacts to stimuli–which explains why a person with schizophrenia may be overwhelmed by sensory information (loud music or bright lights) which other people can easily handle. This problem in processing different sounds, sights, smells and tastes can also lead to hallucinations or delusions.
Structure – Some research suggests that problems with the development of connections and pathways in the brain while in the womb may later lead to schizophrenia.
Viral Infections and Immune Disorders
Schizophrenia may also be triggered by environmental events, such as viral infections or immune disorders. For instance, babies whose mothers get the flu while they are pregnant are at higher risk of developing schizophrenia later in life. People who are hospitalized for severe infections are also at higher risk.
What are the Early Warning Signs of Schizophrenia?
The signs of schizophrenia are different for everyone. Symptoms may develop slowly over months or years, or may appear very abruptly. The disease may come and go in cycles of relapse and remission.
Behaviors that are early warning signs of schizophrenia include:
- Hearing or seeing something that isn’t there
- A constant feeling of being watched
- Peculiar or nonsensical way of speaking or writing
- Strange body positioning
- Feeling indifferent to very important situations
- Deterioration of academic or work performance
- A change in personal hygiene and appearance
- A change in personality
- Increasing withdrawal from social situations
- Irrational, angry or fearful response to loved ones
- Inability to sleep or concentrate
- Inappropriate or bizarre behavior
- Extreme preoccupation with religion or the occult
- Anyone who experiences several of these symptoms for more than two weeks should seek help immediately.
If you or someone you know are in crisis, call 1-800-273-TALK (8255), go to your local Emergency Room, or call 911.
What are the Symptoms of Schizophrenia?
A medical or mental health professional may use the following terms when discussing the symptoms of schizophrenia.
Positive symptoms are disturbances that are “added” to the person’s personality.
- Delusions –false ideas–individuals may believe that someone is spying on him or her, or that they are someone famous (or a religious figure).
- Hallucinations –seeing, feeling, tasting, hearing or smelling something that doesn’t really exist. The most common experience is hearing imaginary voices that give commands or comments to the individual.
- Disordered thinking and speech –moving from one topic to another, in a nonsensical fashion. Individuals may also make up their own words or sounds, rhyme in a way that doesn’t make sense or repeat words and ideas.
- Disorganized behavior –this can range from having problems with routine behaviors like hygiene or choosing appropriate clothing for the weather, to unprovoked outbursts, to impulsive and uninhibited actions. A person may also have movements that seem anxious, agitated, tense or constant without any apparent reason.
Negative symptoms are capabilities that are “lost” from the person’s personality.
- Social withdrawal
- Extreme apathy (lack of interest or enthusiasm)
- Lack of drive or initiative
- Emotional flatness
