Mental disorders to better prevent, detect, and treat mental illness and to alleviate such consequences mental illness is associated with many contributing and/or causative factors. Researchers have discovered that five major mental disorders may be linked to the same common inherited genetic variations, according to a study published in the journal nature genetics. Most genetic diseases are the direct result of a mutation in one gene however, one of the most difficult problems ahead is to further elucidate how genes contribute to diseases that have a complex pattern of inheritance, such as in the cases of diabetes , asthma , cancer , and mental illness.
