In most people with schizophrenia, symptoms generally start in the mid- to late 20s, though it can start later, up to the mid-30s. Schizophrenia is considered early onset when it starts before the age of 18. Onset of schizophrenia in children younger than age 13 is extremely rare.
Adults of all ages may have symptoms of schizophrenia. However, it is rare for symptoms to appear for the first time after the age of 40. Schizophrenia in children under the age of 12 is rare.
In some people, schizophrenia appears suddenly and without warning. But for most, it comes on slowly, with subtle warning signs and a gradual decline in functioning, long before the first severe episode. Often, friends or family members will know early on that something is wrong, without knowing exactly what.
The peak age of onset of schizophrenia is 15 – 25 years in men and 20 – 30 years in women. It is often preceded by a prodromal phase of vague symptoms, some odd behaviours and a decline in functioning at school or work and interpersonally.
The exact causes of schizophrenia are unknown. Research suggests a combination of physical, genetic, psychological and environmental factors can make a person more likely to develop the condition. Some people may be prone to schizophrenia, and a stressful or emotional life event might trigger a psychotic episode.
People with schizophrenia generally live about 15 to 20 years less than those without the condition. Schizophrenia is a complex disease. There are many ways it can result in serious complications.
Borderline schizophrenia is held to be a valid entity that should be included in the DSM-III. It is a chronic illness that may be associated with many other symptoms but is best characterized by perceptual-cognitive abnormalities. It has a familial distribution and a genetic relationship with schizophrenia.
The last stage is the residual phase of schizophrenia. In this phase, you're starting to recover, but still have some symptoms.
Schizophrenia usually involves delusions (false beliefs), hallucinations (seeing or hearing things that don't exist), unusual physical behavior, and disorganized thinking and speech. It is common for people with schizophrenia to have paranoid thoughts or hear voices.
Schizophrenia usually develops slowly, with early warning signs developing before the first severe episode (psychosis). That is when what are known as positive symptoms—those not generally seen in healthy people, such as hallucinations and delusions—are experienced for the first time.
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
Schizophrenia affects approximately 24 million people or 1 in 300 people (0.32%) worldwide. This rate is 1 in 222 people (0.45%) among adults (2). It is not as common as many other mental disorders.
Slightly more men get diagnosed with the condition. Women often get diagnosed later in life than men. In general, the clinical signs of schizophrenia are less severe for women. Some research suggests that the course of the disease tends to be worse in men.
If you, or someone you know, are described as having “borderline schizophrenia”, it could point toward mild symptoms, unclear symptoms, or a combination of symptoms. The best thing you can do is to seek clarification from a licensed professional.
Case Study Illustrates How Schizophrenia Can Often Be Overdiagnosed. Making a diagnosis of schizophrenia requires careful evaluation because the disorder involves much more than what patients perceive as hallucinations.
Schizophrenia can be hard to diagnose for a few reasons. One is that people with the disorder often don't realize they're ill, so they're unlikely to go to a doctor for help. Another issue is that many of the changes leading up to schizophrenia, called the prodrome, can mirror other normal life changes.
Connecting face-to-face with others is the most effective way to calm your nervous system and relieve stress. Since stress can trigger psychosis and make the symptoms of schizophrenia worse, keeping it under control is extremely important.
Most people with schizophrenia make a recovery, although many will experience the occasional return of symptoms (relapses). Support and treatment can help you to manage your condition and the impact it has on your life.
Haloperidol, fluphenazine, and chlorpromazine are known as conventional, or typical, antipsychotics and have been used to treat schizophrenia for years.
Your doctor will do a physical exam. You might also need tests, sometimes including brain imaging techniques such as a CT scan or MRI of the brain. Generally, lab results and imaging studies are normal in people who have schizophrenia.
Past studies have reported that offspring of affected mothers have a higher risk of schizophrenia than the offspring of affected fathers; however, other studies found no such maternal effect [Gottesman and Shields, 1976].
Though schizophrenia can vary from one individual to the next, some of the most commonly occurring symptoms include delusions, hallucinations, and a lack of emotion in speech and in facial expressions.
