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 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.
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.
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.
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 can have a gradual or sudden onset.
The symptoms of schizophrenia usually fall into one of several groups: Positive symptoms are symptoms associated with excess or distortion of normal function. Positive symptoms include delusions, hallucinations, and disorganized thoughts and behaviours.
There are no laboratory tests to diagnose schizophrenia. Instead, a doctor will perform a physical evaluation, review your medical history, and may use various diagnostic tests, such as a blood test, MRI, or CT scan to rule out any other conditions.
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.
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.
Residual schizophrenia is the mildest form of schizophrenia characteristic when positive symptoms of paranoid schizophrenia (hallucinations, delusional thinking) are not actively displayed in a patient although they will still be displaying negative symptoms (no expression of emotions, strange speech).
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
Symptoms of Schizophrenic Episodes. Positive symptoms, which include delusions, hallucinations, paranoia, and psychotic behaviors that are not seen in those without schizophrenia. Cognitive symptoms, which can include difficulty concentrating and disorganized thoughts, speech, and behavior.
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].
When patients have active schizophrenia symptoms, they truly believe in their delusions and hallucinations, and will deny that they are sick. Untreated patients often lack insight into their illness. One way for people with schizophrenia to understand more about their illness is to participate in a peer support group.
The symptoms of schizophrenia are usually classified into: positive symptoms – any change in behaviour or thoughts, such as hallucinations or delusions. negative symptoms – where people appear to withdraw from the world around then, take no interest in everyday social interactions, and often appear emotionless and flat.
Seeing, hearing, or tasting things that others do not. Suspiciousness and a general fear of others' intentions. Persistent, unusual thoughts or beliefs.
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.
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.
Although schizophrenia most commonly presents early in life, at least 20% of patients have onset after the age of 40 years.
Drugs do not directly lead to or cause schizophrenia. However, studies have found that drug abuse increases the odds of developing schizophrenia or other related illnesses. Specific drugs like cocaine, cannabis, LSD, or amphetamines can trigger symptoms of schizophrenia in those more susceptible to the condition.
Haloperidol, fluphenazine, and chlorpromazine are known as conventional, or typical, antipsychotics and have been used to treat schizophrenia for years.
Someone might see lights, objects, people, or patterns. Often it's loved ones or friends who are no longer alive. They may also have trouble with depth perception and distance.
