Mental health problems can be incredibly difficult to treat, but a new discovery could open up new options.
Blood samples were taken from people experiencing their first psychotic episode. Scientists then tested for antibodies, part of our immune system. Of the people tested, 3% had antibodies thought to attack certain brain cells and disrupt how the cells communicate. This might have caused their psychosis.
Even if only a small proportion of people with psychosis could be treated in this new way, it could make a big difference to a lot of lives.
