Abnormal resting-state regional homogeneity in unmedicated bipolar II disorder.

Summary of "Abnormal resting-state regional homogeneity in unmedicated bipolar II disorder."

Previous studies demonstrated that patients with bipolar disorder (BD) exhibited abnormal neural activity in multiple brain regions. However, no study has been conducted to identify regional intrinsic neural activity changes in BD II. In the present study, we used the regional homogeneity (ReHo) approach to explore the regional abnormal neural activity in bipolar II disorder
METHODS:
One hundred unmedicated patients with BD II depression and 100 healthy controls (HC) underwent the resting-state functional magnetic resonance imaging. The ReHo values of each voxel was calculated in the whole brain. The two-sample t-test and threshold-free cluster enhancement (TFCE) correction were applied for the ReHo analysis.

Medical and Biotech [MESH] Definitions

The period of time following the triggering of an ACTION POTENTIAL when the CELL MEMBRANE has changed to an unexcitable state and is gradually restored to the resting (excitable) state. During the absolute refractory period no other stimulus can trigger a response. This is followed by the relative refractory period during which the cell gradually becomes more excitable and the stronger impulse that is required to illicit a response gradually lessens to that required during the resting state.

Planning for health resources at a regional or multi-state level.

A major affective disorder marked by severe mood swings (manic or major depressive episodes) and a tendency to remission and recurrence.

A dibenzothiazepine and ANTIPSYCHOTIC AGENT that targets the SEROTONIN 5-HT2 RECEPTOR; HISTAMINE H1 RECEPTOR, adrenergic alpha1 and alpha2 receptors, as well as the DOPAMINE D1 RECEPTOR and DOPAMINE D2 RECEPTOR. It is used in the treatment of SCHIZOPHRENIA; BIPOLAR DISORDER and DEPRESSIVE DISORDER.
