Brainwave 'fingerprint' could detect psychosis

The development of an early-warning test could drastically help those young people most at risk of developing severe mental illness, researchers claim.

A team of psychologists and psychiatrists at the University of Glasgow, Scotland has received £1 million of funding from the Medical Research Council (MRC) to begin research on a brainwave ’fingerprint’ which could be used to help identify young people at risk of developing serious mental illness.

Researchers are currently looking to recruit 100 volunteers aged between 16 and 35 for the project which will measure their brain activity and examine changes in their mental state for a period of up to two years.

According to the researchers, the Youth Mental Health Risk and Resilience Study (YouR-Study) will use magnetoencephalography (MEG), a brain imaging technique unique to the university in Scotland, to examine a specific set of brainwaves known to be involved in cognitive functions.

The researchers said that one of the main aims of the project is to develop an early-warning system capable of identifying people at high risk of developing psychosis before they fully manifest the symptoms, such as hallucinations or delusions.

YouR-Study will be led by Peter Uhlhaas of the University of Glasgow’s Institute of Neuroscience and Psychology.

“The study will be the first of its kind to use MEG to investigate links between neural oscillations and their synchronisation, which recent research has shown may well play a role in the development of psychosis,” Uhlhass said.

“MEG, which is similar to electroencephalography (EEG)uses very sensitive magnetometers to record magnetic fields produced by electrical currents occurring naturally in the brain, creating a sophisticated map of brain activity,” he added.

So of the 100 people sampled they might not get a group with a single sz person since the chance of getting it is .5-1%? They might just be mapping all normies brains.

They could be focusing their efforts on a hundred people that come from a higher risk family environment (e.g. people with a family history of mental illness or schizophrenia). But you are right - if they are just samping 100 people from the general population - they might not get anyone with risk of schizophrenia.

The study homepage doesn’t really say too much, just what they are doing and their contact info. Not the how stuff.

I think the screening process will probably result in the selection of a group with a high risk of psychosis. Then I’m guessing a % would probably go onto develop psychosis. The idea is probably to compare those who do v those who don’t.
It might result in a very small sample size and the need for replication with a larger group of people.
