An altered white matter region of the brain was found to limit the brain's conscious access to information, potentially contributing to delusions and other psychotic symptoms of mental health disorders, stated new study published in JNeurosci.
Dysfunction in white matter tracts may explain the delusions, which are characteristic of psychiatric disorders like bipolar disorder and schizophrenia.
Berkovitch et al. used MRI to compare the white matter structure and consciousness threshold of healthy adults, bipolar disorder patients with and without psychotic symptoms, and schizophrenia patients.
Lower thresholds correlated with increased white matter connectivity in long-distance tracts.
The study results revealed that mean altered white matter connectivity does not induce psychosis directly but may affect the consciousness threshold.
