Schizophrenia is a mental disorder characterized by a breakdown of thought processes and by poor emotional responsiveness. It most commonly manifests itself as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction.
studies have found that people with schizophrenia are about twice as likely to smoke pot as those who are unaffected. Conversely, data suggest that those who smoke cannabis are twice as likely to develop schizophrenia as nonsmokers.
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- common behaviors among teens. A combination of factors can predict schizophrenia in up to 80 percent of youth who are at high risk of developing the illness.
Not everyone will experience the same symptoms, but some symptoms of schizophrenia, such as hearing voices, are common to many. Schizophrenia alters the way people think and feel, so that perceptions may be changed and thinking can be disturbed. This is very disabling for them and very distressing for their families, who often become the primary caregivers.
While research has shown that schizophrenia affects men and women equally and occurs in similar rates in all ethnic groups around the world, its symptoms differ from person to person and can fluctuate over time. When the disease is active, it can be characterized by episodes in which the patient is unable to distinguish between real and unreal experiences.
The disease can thus impact every aspect of affected people's work, family, and social life. Though not affected directly, family members also frequently become distressed and overwhelmed by the difficulties involved in providing care and in coming to terms with the transformation of their loved one into a patient with a serious chronic illness.
Despite a hundred years' research, the neuropathology of schizophrenia remains obscure. However, neither can the null hypothesis be sustained—that it is a `functional' psychosis, a disorder with no structural basis. A number of abnormalities have been identified and confirmed by meta-analysis, including ventricular enlargement and decreased cerebral (cortical and hippocampal) volume.
The causes of schizophrenia aren’t known for sure. It’s likely that several different factors, a combination of which will vary from person to person, may have an affect.
Schizophrenia is found all over the world. The severity of the symptoms and long-lasting, chronic pattern of schizophrenia often cause a high degree of disability. Medications and other treatments for schizophrenia, when used regularly and as prescribed, can help reduce and control the distressing symptoms of the illness.
Schizophrenia is a disabling, chronic, and severe mental illness that affects more than 2 million Americans age 18 and over. Symptoms include hearing internal voices, thinking that other people are reading one's mind, controlling one's thoughts, or plotting harm, which may leave a person feeling fearful and withdrawn.
Schizophrenia usually starts between the late teens and the mid-30s, whereas onset prior to adolescence is rare (although cases with age at onset of 5 or 6 years have been reported). Schizophrenia can also begin later in life (e.g., after age 45 years), but this is uncommon.
