A group of researchers from Spain and the U.S. have found that schizophrenia is actually a group of eight genetically different types of diseases, each of which presents its own set of symptoms.
Scientists from the universities of Granada (Spain) and Washington in St. Louis have published their research in the American Journal of Psychiatry.
Experts believe this could be an important first step towards a better diagnosis and treatment of this disease, which affects approximately one percent of the world’s population.
Researchers were aware that approximately 80 percent of the risk of suffering from schizophrenia was hereditary, although scientists have struggled for years to identify which specific genes lead to it.
The new study included 4196 patients diagnosed with schizophrenia and 3200 healthy patients. Experts were, for the first time, able to identify the different genes networks that contribute to the existence of eight different types of schizophrenia.
