Summary: A blood test, when used in psychiatric patients experiencing symptoms that are considered to be indicators of a high risk for psychosis, identifies those who later went on to develop psychosis, preliminary results of a new study show.
Scientists have discovered that testing the levels of certain proteins in blood samples can predict whether a person at risk of psychosis is likely to develop a psychotic disorder years later.
There's no test to positively diagnose psychosis. However, your GP will ask about your symptoms and possible causes. For example, they may ask you: whether you're taking any medicines.
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.”
Signs of early or first-episode psychosis
Hearing, seeing, tasting or believing things that others don't. Persistent, unusual thoughts or beliefs that can't be set aside regardless of what others believe. Strong and inappropriate emotions or no emotions at all. Withdrawing from family or friends.
Psychosis could be triggered by a number of things, such as: Physical illness or injury. You may see or hear things if you have a high fever, head injury, or lead or mercury poisoning. If you have Alzheimer's disease or Parkinson's disease you may also experience hallucinations or delusions.
Brain tumors and brain injury.
Some brain tumors may cause psychotic symptoms that seem like schizophrenia. Likewise, people who've had a traumatic brain injury may have symptoms such as psychosis.
There's no single test for schizophrenia and the condition is usually diagnosed after assessment by a specialist in mental health. If you're concerned you may be developing symptoms of schizophrenia, see a GP as soon as possible. The earlier schizophrenia is treated, the better.
Your experience of psychosis will usually develop gradually over a period of 2 weeks or less. You are likely to fully recover within a few months, weeks or days.
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.
The specific cause of a psychotic disorder is not known, but several factors can make you more likely to develop one. Some risk factors include: A brain injury, including a stroke or traumatic brain injury. A family history of schizophrenia, other psychotic disorders, or mood disorders.
Unlike taking someone's temperature, recognizing whether psychosis is present can be difficult – especially when it is in its early stages. These early stages can be associated with a wide variety of nonspecific changes such as mood swings, taking up of new philosophies or “odd” behaviours or beliefs.
Psychosis can be very serious, regardless of what is causing the symptoms. The best outcomes result from immediate treatment, and when not treated psychosis can lead to illness, injuries, legal and financial difficulties, and even death.
Recovery from a first episode of psychosis varies from person to person. Sometimes symptoms go away quickly and people are able to resume their regular life right away. Other people may need several weeks or months to recover, and they may need support over a longer period of time.
An episode of psychosis is treatable, and it is possible to recover. It is widely accepted that the earlier people get help the better the outcome. 25% of people who develop psychosis will never have another episode, another 50% may have more than one episode but will be able to live normal lives.
Evidence suggests that early treatment—and a shorter DUP—promotes better symptom improvement and overall functioning in everyday life. There is yet inadequate proof to say conclusively that psychosis causes permanent brain damage.
First-episode psychosis (FEP) can result in a loss of up to 1% of total brain volume and up to 3% of cortical gray matter. When FEP goes untreated, approximately 10 to 12 cc of brain tissue—basically a tablespoon of cells and myelin—could be permanently damaged.
Antipsychotics. Antipsychotic medicines are usually recommended as the first treatment for psychosis. They work by blocking the effect of dopamine, a chemical that transmits messages in the brain.
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.
If schizophrenia is suspected, a complete blood count (CBC) test is helpful to monitor the general health of the patient and rule out other conditions that may have been responsible for their symptoms. In particular, signs of drug overuse can sometimes be confused with schizophrenia symptoms.
Psychosis is not a life sentence
Psychosis may not be permanent. However, if someone isn't treated for psychosis, they could be at greater risk for developing schizophrenia or another psychotic disorder. Schizophrenia is rare, but people who have it are at increased risk for premature death and suicide.
It is possible for anxiety to lead to psychosis symptoms when a person's anxiety is particularly severe. However, such an instance of psychosis is different from an actual psychotic disorder in the cause and treatment approaches.
Avoid drugs and alcohol.
While you might want to use drugs or alcohol to cope with difficult feelings, in the long run they can make you feel a lot worse and can prevent you from dealing with any underlying problems that the drug or alcohol use may have been masking.
Antipsychotic medicines, also known as neuroleptics, are usually recommended as the first treatment for psychosis. They work by blocking the effect of dopamine, a chemical that transmits messages in the brain. However, they're not suitable or effective for everyone, as side effects can affect people differently.
