Often these factors are then blamed for the onset of the illness when, in fact, the illness itself has caused the stressful event. It is not, therefore, always clear whether stress is a cause or a result of schizophrenia. Alcohol and other drug use Harmful alcohol and other drug use, particularly cannabis and amphetamine use, may trigger psychosis in people who are vulnerable to developing schizophrenia.
While substance use does not cause schizophrenia, it is strongly related to relapse. People with schizophrenia are more likely than the general population to use alcohol and other drugs, and this is detrimental to treatment. A considerable proportion of people with schizophrenia have been shown to smoke, which contributes to poor physical health.
What are the symptoms of schizophrenia? What causes schizophrenia? Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior that impairs daily functioning, and can be disabling. People with schizophrenia require lifelong treatment. Early treatment may help get symptoms under control before serious complications develop and may help improve the long-term outlook.
Schizophrenia involves a range of problems with thinking cognition , behavior and emotions. Signs and symptoms may vary, but usually involve delusions, hallucinations or disorganized speech, and reflect an impaired ability to function. Symptoms may include:. Symptoms can vary in type and severity over time, with periods of worsening and remission of symptoms. Some symptoms may always be present.
In men, schizophrenia symptoms typically start in the early to mids. In women, symptoms typically begin in the late 20s. It's uncommon for children to be diagnosed with schizophrenia and rare for those older than age Schizophrenia symptoms in teenagers are similar to those in adults, but the condition may be more difficult to recognize.
This may be in part because some of the early symptoms of schizophrenia in teenagers are common for typical development during teen years, such as:. Also, recreational substance use, such as marijuana, methamphetamines or LSD, can sometimes cause similar signs and symptoms.
People with schizophrenia often lack awareness that their difficulties stem from a mental disorder that requires medical attention. So it often falls to family or friends to get them help. If you think someone you know may have symptoms of schizophrenia, talk to him or her about your concerns. Those with the condition may hear imaginary voices and believe others are reading their minds, controlling their thoughts or plotting to harm them.
Most people with schizophrenia suffer from symptoms either continuously or intermittently throughout life and are often severely stigmatized by people who do not understand the disease. However, the symptoms are terrifying to those afflicted and can make them unresponsive, agitated or withdrawn. People with schizophrenia attempt suicide more often than people in the general population, and estimates are that up to 10 percent of people with schizophrenia will complete a suicide in the first 10 years of the illness — particularly young men with schizophrenia.
While schizophrenia is a chronic disorder, it can be treated with medication, psychological and social treatments, substantially improving the lives of people with the condition. Scientists believe that many different genes may increase the risk of schizophrenia development, but that no single gene causes the disorder by itself. It is not yet possible to use genetic information to predict who will develop schizophrenia. Schizophrenia can have very different symptoms in different people. The way the disease manifests itself and progresses in a person depends on the time of onset, severity, and duration of symptoms, which are categorized as positive, negative and cognitive.
All three kinds of symptoms reflect problems in brain function. Relapse and remission cycles often occur; a person can get better, worse and better again repeatedly over time. Schizophrenia affects men and women equally.
It occurs at similar rates in all ethnic groups around the world. Symptoms such as hallucinations and delusions usually start between ages 16 and Men tend to experience symptoms earlier than women.
Most of the time, people do not get schizophrenia after age Schizophrenia rarely occurs in children , but awareness of childhood-onset schizophrenia is increasing. It can be difficult to diagnose schizophrenia in teens. This is because the first signs can include a change of friends, a drop in grades, sleep problems and irritability — behaviors that are common among teens.
For more information about youth and schizophrenia, check out episodes from season four of Healthy Minds With Dr. Jeffrey Borenstein which are available to view on our website. A combination of factors can predict schizophrenia in up to 80 percent of youth who are at high risk of developing the illness.
These factors include isolating oneself and withdrawing from others, an increase in unusual thoughts and suspicions, and a family history of psychosis. Currently, schizophrenia is diagnosed by the presence of symptoms or their precursors for a period of six months.
Two or more symptoms, such as hallucinations, delusions, disorganized speech, and grossly disorganized or catatonic behavior, must be significant and last for at least one month.
Foundation-funded research to find markers, such as abnormal brain scans or blood chemicals that can help detect early disease and allow for quicker interventions is now being done. Scientists are also working to understand the genetic and environmental mechanisms that combine to cause schizophrenia.
As more is discovered about chemical circuitry and structure of the brains of people with the disease, better diagnostic tools and early intervention techniques can be developed. This is crucial for schizophrenia as it is believed that with every psychotic episode, increased damage is done to the brain. While no cure exists for schizophrenia, it is treatable and manageable with medication and behavioral therapy , especially if diagnosed early and treated continuously.
You may abandon hobbies and activities, and your performance at work or school can deteriorate. While these warning signs can result from a number of problems—not just schizophrenia—they are cause for concern. When out-of-the-ordinary behavior is causing problems in your life or the life of a loved one, seek medical advice.
If schizophrenia or another mental problem is the cause, getting treatment early will help. However, the symptoms of schizophrenia vary dramatically from person to person, both in pattern and severity. Not every person with schizophrenia will have all the symptoms, and the symptoms of schizophrenia may also change over time. Often, these delusions involve illogical or bizarre ideas or fantasies, such as:.
These harassing delusions often involve bizarre ideas and plots e. Delusions of reference — A neutral environmental event is believed to have a special and personal meaning.
For example, you might believe a billboard or a person on TV is sending a message meant specifically for you. Delusions of grandeur — Belief that you are a famous or important figure, such as Jesus Christ or Napoleon.
Alternately, delusions of grandeur may involve the belief that you have unusual powers, such as the ability to fly. Delusions of control — Belief that your thoughts or actions are being controlled by outside, alien forces. Hallucinations are sounds or other sensations experienced as real when they exist only in your mind. While hallucinations can involve any of the five senses, auditory hallucinations e.
These often occur when you misinterpret your own inner self-talk as coming from an outside source. Schizophrenic hallucinations are usually meaningful to you as the person experiencing them. Schizophrenia can cause you to have trouble concentrating and maintaining your train of thought, which may manifest itself in the way that you speak.
You may respond to queries with an unrelated answer, start sentences with one topic and end somewhere completely different, speak incoherently, or say illogical things. Loose associations — Rapidly shifting from topic to topic, with no connection between one thought and the next.
Perseveration — Repetition of words and statements; saying the same thing over and over. Schizophrenia disrupts goal-directed activity, impairing your ability to take care of yourself, your work, and interact with others. Disorganized behavior appears as:. Lack of emotional expression — Inexpressive face, including a flat voice, lack of eye contact, and blank or restricted facial expressions.
Seeming lack of interest in the world — Apparent unawareness of the environment; social withdrawal. Speech difficulties and abnormalities — Inability to carry a conversation; short and sometimes disconnected replies to questions; speaking in a monotone. Daniel is 21 years old. Six months ago, he was doing well in college and holding down a part-time job in the stockroom of a local electronics store. But then he began to change, becoming increasingly paranoid and acting out in bizarre ways.
From there, his condition got worse. Daniel stopped bathing, shaving, and washing his clothes. Then he started hearing voices telling him to find the bugs and deactivate them. His frightened boss called the police, and Daniel was hospitalized. Beginning treatment as soon as possible with an experienced mental health professional is crucial to your recovery. A diagnosis of schizophrenia is not a life-sentence of ever-worsening symptoms and recurring hospitalizations.
With the right treatment and self-help , many people with schizophrenia are able to regain normal functioning and even become symptom-free.
