Find out the cause of schizophrenia

British scientists have determined that failure in the chemical system that transmits information to the brain is the cause of schizophrenia.

For the first time, scientists have a harmless method to scan the brain of living people (Photo: TTO) By brain scanning, experts from the British Institute of Psychiatry compared brain scans set of people with schizophrenia and brain scans of healthy volunteers.

They found a problem in the chemical bond needed to make nerve cells "talk" to each other.

Scientists identified the finding as important, but they said: "Schizophrenia is not merely caused by a chemical imbalance."

The single photon emission tomography method helps scientists examine the operation of this chemical system by releasing a radiation that stimulates the activity of the NDMA sensor.

The data collected showed that the left hemisphere of the schizophrenic patients was very weak and the signals often did not reach each other. This brain region is thought to control learning, cognition and memory.

However, patients taking the drug have good results through the test. The drugs they use seem to increase the level of glutamate, while also affecting other brain chemical systems. However, drugs can cause harmful side effects such as Parkinson's paralysis.

Lead researcher Professor Lyn Pilowsky said: "This is the first time we have a harmless method to scan the brains of living people. This allows for new ways of diagnosis and treatment. more effective for schizophrenic patients. "

However, he added: "In addition to chemical imbalance, childhood poverty and psychological trauma are also the cause of this disease . "
