Stated in the John Hopkins Neurology and Neurosurgery journal " Brain Waves" ( Potash , 2004 ) illustrates the idea which came from German psychiatrist Emil Kraipelin in the 1800's that schizophrenia and bipolar disorder are distinct from each other by visualizing them as two trees in a forest of mental illness. As a result began the separation of the diseases that marks today's psychiatry. Potash also states that "If we knew the genes associated with psychotic symptoms, we'd have an anchor, a point to investigate their action in the brain." He then reminds us of the importance in regards to treatments in these disorders which would come after an understanding of the genes which cause these respected conditions ( Potash , 2004 ). Therefore in this article I will expound on current studies into the common genetic disorders of schizophrenia and bipolar.
According to ( Craddock et al., 2005 ) mental disorders are currently one of the major causes of death and also effect a variety of people around the globe. It is also known that genetic factors play a role by contributing to an individual by causing a lack of the ability to resist many of the common genetic disorders. Furthermore, the most severe psychiatric disorders of adult onset are called functional psychoses, which for a century have been subdivided into schizoprenia, and bipolar disorder. In addition ( Craddock et al., 2005 ) recognize the hours of research which are trying to pinpoint the susceptibility genes which cause schizophrenia and bipolar genetic disorders.
In reference to bipolar disorders, ( Craddock et al., 1999 ) define it as a complicated genetic disorder where the central attraction is a pathological disarrangement in mood that varies between two extremes one being an extreme state of happiness and the other being severe depression. They also note that troubles in thinking and in behavior as well as hallucinations are associated with bipolar disorders. The total...
