During a manic episode, people often have remarkable energy and move, think, and talk rapidly.
They sleep little but do not appear to be tired. They may also experience delusions such as the belief that they are able to fly or are Jesus or another famous person.

Words are spoken, but the connections between sentences or paragraphs are illogical. This is called a formal thought disorder. Psychiatrists often see patients with a mixture of the above symptoms, and it may be difficult to determine whether a patient has schizophrenia or bipolar disorder even after following him or her for many years.
Such patients may receive a diagnostic label of schizoaffective disorder, bipolar type. Genes and environment both contribute to the causes of bipolar disorder and schizophrenia. In terms of genetic factors, it appears that small changes in a large number of genes can add up and increase the risk of someone developing one of these disorders.
Some genes are more related to the development of schizophrenia, and other genes are more related to bipolar disorder. However, some genes seem to be related to both disorders. In other words, some abnormalities in the same genes may be shared by schizophrenia and bipolar disorder.
Meda and colleagues recently published a study in Biological Psychiatry that compared the interactions between specific brain systems in several groups of people: This research team used functional brain imaging to examine the interrelationships among 5 brain networks.
A brain network is composed of brain regions that function together and are responsible for activities of the mind such as motivationemotion, and cognition memoryattention, planning, etc. Networks interact with each other, and various behaviors are likely related to these interactions. The 5 networks that were examined in this study involved 1 visual processing, 2 social awareness, 3 recognizing and interpreting emotions, 4 integrating language with emotions and planning, and 5 control and regulation of movement and timing of responses.
Each of these networks involves a number of specific brain structures that are increasingly well understood. How do these 5 networks interact in persons with schizophrenia or bipolar disorder compared to healthy controls?
It turns out that patients with schizophrenia had a diminished interaction between two of these specific networks when compared to either controls or persons with bipolar disorder.Schizophrenia Information > Facts: Schizophrenia Facts and Statistics: Schizophrenia is a serious disorder of the mind and brain but it is also highly.
