Schizophrenia blood tests developed with latest research

Up to now, the diagnosis of mental diseases is extremely subjective and largely centered on clinical interviews. This may now be supported with a new, low cost blood test developed included in a European research study.

Researchers at the Department of Chemical Engineering and Biotechnology at the University of Cambridge have now been focusing on a blood test for schizophrenia for a long time.

Preliminary assessments were too costly, but they’ve now created a brand new model which, they claim, is cheaper and provides more in depth information. The test analyses proteins within the patient’s body to tell apart between different types of mental diseases.

Based on the experts, with the brand new check schizophrenia could be identified with a certainty of 83 percent and despair with a certainty around 90 percent.

“At as soon as the issue with psychological problems is the fact that we think it’s all-in your brain and it’s something is very subjective. But, if your patient can also view some problem in the body, you can relate genuinely to it in real life,” described Sabine Bahn, professor of molecular psychiatry at the University of Cambridge.

For Kirsty Trigg, who is affected with schizophrenia, the check has made an impact, enabling her to be clinically diagnosed. Since she’s use of proper treatment, she says she’s more in control of her everyday life.

In the 2001 film, “A Beautiful Mind,” mathematician and Nobel Prizewinner John Nash fought with the devastating mental disorder schizophrenia for a long time before being correctly diagnosed and treated. For some and families dealing with this illness, early treatment is crucial.

A new blood-based test may help with that work. The test, called VeriPsych, searches for biomarkers of schizophrenia in an individual’s body, and may be the first such diagnostic test designed to assist psychiatrists in confirming the diagnosis of new-onset schizophrenia, researchers say.

The way the test works

VeriPsych steps biomarkers, which are proteins or snippets of genetic material present in the system, that may be a sign of the problem or illness. Researchers have discovered 51 of those substances related to schizophrenia.

“There are lots of people that think that schizophrenia is just a systemic disease,” said study investigator Dr. Michael Spain, chief medical officer at Rules-Based Medicine, the organization that makes the test and funded the study. “It’s that its best manifestations have been in the mind.”

To create a diagnosis, the biomarker report of the suspected schizophrenia patient is compared with that of the patient with the condition.

In a current study led by Spain, biomarkers in blood samples from 577 patients with schizophrenia in a variety of stages of disease including some who’d recently experienced a preliminary psychotic episode, and some were chronically ill were assessed against those of 229 people minus the condition. Scientists found the test to be accurate in detecting 83 percent of people.

The 51 biomarkers were still recognizable after some people experienced 4 to 6 months of treatment, the researchers said.

The finding, comprehensive in May in the journal Biomarker Observations, wasn’t widely reported. The organization recently issued a media release about the study.

The check was especially successful in hard circumstances, with individuals who’d experienced numerous psychotic symptoms, Spain said.

“There’s a specific amount of rejection whenever a child is identified as having schizophrenia. You want that your son or daughter didn’t have that,” Spain informed MyHealthNewsDaily. “It’s a great test to persuade parents and sometimes even the in-patient to remain on treatment, in the place of simply subjective viewpoint.”

However, VeriPsych scientists warn this blood-based test isn’t designed to give a definitive diagnosis for schizophrenia. Currently, they’re creating a test that will distinguish between schizophrenia and other mental illnesses, such as for instance bipolar and major despression symptoms.

Can a blood test actually identify a mental illness?

Some doctors are skeptical of the test. While recognizing the requirement and possibility of counting on techniques apart from individual studies or findings, the technology isn’t there yet, said Dr. Gregory Light, a co-employee professor of psychiatry at the University of California, North Park.

“Body-based assessments, right now, are a long way away from being helpful for a person patient,” Light said. “As an example, [genetic tests] raise more questions than they answer, account for merely a few cases, and the advancements in technology are rapidly outpacing our capability to understand the outcomes.”

The biomarkers that some research has suggested are related to schizophrenia may be due to the condition, or long term utilization of antipsychotic treatment, said Dr. Irving Gottesman, a professor emeritus of psychology at the University of Minnesota.

“It requires, usually, a period of time of observation, both with and without treatment of 6 months or even more, to obtain a better ‘feel’ for what may be the correct analysis,” Gottesman said.

Currently, individuals with schizophrenia are identified through interviews with a health care provider. The analysis, like those of numerous mental illnesses, is created on the basis of the standards established by the guide book Diagnostic and Statistical Manual of Mental Disorders (DSM).

To be diagnosed, an individual needs to be struggling with two or more prevalent symptoms for about 30 days or less. Symptoms include delusions, hallucinations, movement problems, difficulty concentrating, poor working-memory and insufficient pleasure in day to day activities. Diagnosis can be difficult since symptoms of schizophrenia can also mimic other problems like depression, anxiety or bipolar disorders.

Approximately 2.4 million American adults, or 1.1 percent of individuals ages 18 or older, suffer with schizophrenia, based on the National Institute of Mental-Health. Less than half receive appropriate anti-psychotic medication or psychosocial interventions, based on a July 2004 survey from the Agency for Healthcare Research and Quality.
