Men and women are equally likely to get this brain disorder, but guys tend to get it slightly earlier. On average, men are diagnosed in their late teens to early 20s. Women tend to get diagnosed in their late 20s to early 30s. People rarely develop schizophrenia before they're 12 or after they're 40.
It usually starts between ages 15 and 25 for men and between 25 and 35 for women. It also tends to affect men and women in equal numbers. Schizophrenia in children, especially before age 18, is possible but rare. However, these cases are usually very severe.
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].
Schizophrenia and heredity
While the risk is 1 percent in the general population, having an FDR such as a parent or sibling with schizophrenia increases the risk to 10 percent.
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.
Risk factors
Having a family history of schizophrenia. Some pregnancy and birth complications, such as malnutrition or exposure to toxins or viruses that may impact brain development. Taking mind-altering (psychoactive or psychotropic) drugs during teen years and young adulthood.
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.
Although there is no proven way to prevent schizophrenia, scientists are looking for ways to make it less likely. Schizophrenia is a complex illness that may partly involve your genes. But events in your life may also play a role. The condition can sometimes run in families.
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.
Results: In patients with schizophrenia, MR imaging shows a smaller total brain volume and enlarged ventricles. Specific subcortical regions are affected, with reduced hippocampal and thalamic volumes, and an increase in the volume of the globus pallidus.
It's possible that excessive or inappropriate "pruning" of neural connections could lead to the development of schizophrenia, the researchers speculated. This would explain why schizophrenia symptoms often first appear during the teen years, the researchers said.
Those risk factors include genetic mutations you inherit from one or both parents, exposure to certain chemicals or substances, complications during pregnancy and recreational drug use. However, experts have yet to uncover any confirmed triggers or causes for this condition.
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
However, the impact of schizophrenia tends to be highest in Oceania, the Middle East, and East Asia, while the nations of Australia, Japan, the United States, and most of Europe typically have low impact.
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.
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.
Drastic changes in behaviour may occur, and the person can become upset, anxious, confused, angry or suspicious of those around them. They may not think they need help, and it can be hard to persuade them to visit a doctor. Read more about understanding psychotic experiences.
When people with schizophrenia live without adequate treatment, their mental health can worsen. Not only can the signs of schizophrenia get more severe, but they can also develop other mental health disorders, including: Obsessive-Compulsive Disorder (OCD) Anxiety Disorders.
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.
Schizophrenia is a chronic disorder that may wax and wane in severity, but it does not typically worsen with age. 1 For some people, the symptoms of schizophrenia will improve over time while for others the symptoms will stay the same or get worse.
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.
Schizophrenia can have a gradual or sudden onset.
For those who experience mild symptoms initially, the first signs may be withdrawal from friends or social activities, poor school performance, caring less about personal appearance, and perceiving things differently.
Abstract. Many individuals with schizophrenia are unaware of the symptoms and consequences of their illness. Unawareness of schizophrenia is linked to poorer adherence to treatment and is a risk factor for a range of poorer outcomes.
