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 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 can usually be diagnosed if: you've experienced 1 or more of the following symptoms most of the time for a month: delusions, hallucinations, hearing voices, incoherent speech, or negative symptoms, such as a flattening of emotions.
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.
Although schizophrenia most commonly presents early in life, at least 20% of patients have onset after the age of 40 years.
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 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.
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).
Early Warning Signs of Schizophrenia
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.
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.
Though symptoms of active schizophrenia may seem to come on suddenly, the condition takes years to develop. In the early prodromal phase, symptoms aren't always obvious, as you'll see when you read about this first phase.
The risk for schizophrenia has been found to be somewhat higher in men than in women, with the incidence risk ratio being 1.3–1.4. Schizophrenia tends to develop later in women, but there do not appear to be any differences between men and women in the earliest symptoms and signs during the prodromal phase.
Highly stressful or life-changing events may sometimes trigger schizophrenia. These can include: being abused or harassed. losing someone close to you.
The prevalence of comorbid anxiety disorders (panic disorder, social anxiety disorder, and OCD) in schizophrenia is significantly higher in the general population. The onset of anxiety disorder commonly precedes the onset of schizophrenia.
Without treatment, a person with schizophrenia can undergo brain damage, though experts debate the mechanisms through which this happens. People with schizophrenia also have higher rates of liver disease, diabetes, and heart disease than their peers.
Schizophrenia Symptoms and Diagnosis
It is not possible to live a normal life if schizophrenic symptoms go ignored, undiagnosed, and untreated.
If left untreated, schizophrenia rarely gets better on its own. Symptoms of schizophrenia more frequently increase in intensity without treatment and may even lead to the onset of additional mental issues, including: Depression.
Although schizophrenia can occur at any age, the average age of onset tends to be in the late teens to the early 20s for men, and the late 20s to early 30s for women. It is uncommon for schizophrenia to be diagnosed in a person younger than 12 or older than 40. It is possible to live well 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.”
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.
Having schizophrenia could affect your ability to drive. If you've had or currently suffer from a medical condition or disability that may affect your driving you must tell the Driver & Vehicle Agency (DVA).
Research suggests that schizophrenia occurs due to a combination of genetic and environmental factors, which can cause abnormal development in the brain. In people with these risk factors, severely stressful life events, trauma, abuse, or neglect may trigger the condition.
