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.
The most common early warning signs include:
Depression, social withdrawal. Hostility or suspiciousness, extreme reaction to criticism. Deterioration of personal hygiene. Flat, expressionless gaze.
Common early signs of schizophrenia vary by age group and include: Young children: Delayed development. Older kids and teens: Depression, isolation, behavioral problems (e.g., stealing) or changes (e.g., bizarre or unusual thoughts or actions), and trouble focusing.
While it was once thought to be a disease that only worsened over time, schizophrenia is now known to be manageable thanks to modern treatment practices. With a dedication to ongoing treatment, often beginning with intensive residential care, most individuals can live normal or almost-normal lives.
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.
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].
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.
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.
Auditory hallucinations, “hearing voices,” are the most common in schizophrenia and related disorders. Disorganized thinking and speech refer to thoughts and speech that are jumbled and/or do not make sense.
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).
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.
Bipolar disorder.
Some people with severe bipolar disorder have delusions or hallucinations. That's why they may be misdiagnosed with schizophrenia.
Neurological soft signs (NSS) comprise subtle deficits in sensory integration, motor coordination, and sequencing of complex motor acts, which are typically observed in the majority of schizophrenia patients, including chronic cases and neuroleptic-naïve first-episode patients.
Most commonly though, people diagnosed with schizophrenia will hear multiple voices that are male, nasty, repetitive, commanding, and interactive, where the person can ask the voice a question and get some kind of answer.”
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
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.
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.
The prodromal stage consists of non-specific symptoms, such as lack of motivation, social isolation, and difficulty concentrating. Prodromal symptoms are not always obvious. As a result, diagnosing schizophrenia in this stage can be extremely difficult.
Symptoms of psychosis include delusions (false beliefs) and hallucinations (seeing or hearing things that others do not see or hear). Other symptoms include incoherent or nonsense speech and behavior that is inappropriate for the situation.
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.
Doctors don't think there's just one “schizophrenia gene.” Instead, they think it takes many genetic changes, or mutations, to raise your chances of having the mental illness. You're more likely to get schizophrenia if someone in your family has it.
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.
Armed with her previous research, Bahn and her team detailed a panel of blood biomarkers in individuals who have an increased risk of schizophrenia but have no visible symptoms yet. The test, says Bahn, can accurately predict whether someone will “develop schizophrenia over the next two years.”
