Having one pole or process as in the case of a nerve cell with one AXON. As applied to an electrode, the term is something of a misnomer. A second electrode is needed to complete the circuit, but this is often attached at a remote point from the point of application of the electrode.

Patient discussion about unipolar

Q. Bipolar depression And Unipolar depression Is bipolar depression different from unipolar depression?

A. Yes. These are two different disorders that are distinct in many ways: bipolar appears earlier (20's compared to middle aged), males and females are affected equally (depression is more prevalent among women), family tendency (more pronounced in bipolar) etc. The course is also different: bipolar have manic episodes, while depression includes only depressive episodes.

The treatment is also quite different (lithium and stabilizers for bipolar, SSRI for depression)

Although the family functioning and caregiving burden were found varying across different diagnoses of SMI (e.g., those with unipolar disorder had significantly higher family functioning and those with psychotic disorders had much high family burden than those with both unipolar and bipolar disorders) [32], these significant relationships may reveal the impacts of the patients' perceived EE on their family members' health and well-being in caring for a relative with MI [2, 11].
The patients with unipolar disorder expressed significantly higher perceived EE of their family members than those with the other three illness subgroups (schizophrenia, psychotic disorders, and bipolar disorder), in terms of the mean total score and most of the four subscales, and those with bipolar disorder reported the relatively lowest mean total and subscale scores among the four subgroups of SMI.
However, when compared to another study conducted by Gerlsma and Hale III [2] in 26 depressed outpatients using the Dutch version of LEE scale, the mean values of the total score and two subscales (intrusiveness/hostility and emotional involvement) among the patients with unipolar disorder in this study are much higher than the adjusted mean values reported by their participants (i.e., mean total score of 132.86 versus 105.43, mean "intrusiveness/hostility" score of 30.52 versus 28.12, and mean "emotional involvement" score of 34.98 versus 33.70, resp.).
