The depressive symptoms of Unipolar and Bi-polar be feelings of worthlessness and guilt, damage of longing and libido and lack of energy, interest and motivation. The manic symptoms of Bipolar be hyperactivity and overconfidence, belt along thoughts and rapid speech and frenzied and incoherent activity. The biological and cognitive explanations are the strongest for unipolar depression, and the biological is the favourite(a) explanation for Bi-polar depression. biological explanation suggests that transmitteds are a constitute of what you get from your parents, if one or both of your parents have a vulnerability to depression, then there is a possibility it dope be transmitte d to you. Family and alikenesss studies suggest a transmissible basis, with a family history increasing the risk of developing the disorder. Twin studies parade higher harmoniousness rate for superposable monozygotic (MZ) matchs. empirical evidence to support higher concordance of Unipolar in (MZ) twins is McGuffin’s research, were he studies 177 sets of twins.

For Unipolar depression, the concordance rates were 46% for undistinguishable (MZ) twins and 20% for non identical dizygotic (DZ) twins, indicating a genetic component. The genetic role in bipolar depression seems to be much higher than in unipolar depression. Empirical ev idence to support this is Price’s the! ater of operations; price found concordance of 68% for MZs raised together, 67% for separated MZs and 23% for DZs. These rates luff a genetic component for bipolar depression. The strengths of this explanation are in twin studies (MZ) show and share depression than fraternal (DZ) twins. And bipolar is more genetically determined, as 80% of identical twins and 16% of fraternal twins...If you want to get a full essay, order it on our website: BestEssayCheap.com
