Scientists produce strongest evidence yet of schizophrenia’s causes

An international team of scientists led by Cardiff University researchers has provided the strongest evidence yet of what causes schizophrenia – a condition that affects around 1% of the global population.

Published today in the journal Neuron, their work presents strong evidence that disruption of a delicate chemical balance in the brain is heavily implicated in the disorder.

In the largest ever study of its kind, the team found that disease-linked mutations disrupt specific sets of genes contributing to excitatory and inhibitory signalling, the balance of which plays a crucial role in healthy brain development and function.
