There has been some evidence that depresion can be genetic shown recently. Lots of research and studying of the brain and genetics is being done todetermine whether an individual is likely to inherit depression. Most of the research that has been published though, is about bipolar depression. However, it is believd that since unipolar depression can be inherited, it is a biological disease.

Other evidence that depression is a biological illness is that there are higher than normal discharges of cortisol in the adrenal glands of depressives. Also, there are eccentric wave patterns that can be shown with electroencephalograms. The most known theory of this aspect of depression is that the neurobiological basis of depression is a shortage of noradrenalin and serotonin in the synaptic clefts. Due to this theory the serotonin system is the most researched and widely studied, though there are many other neurotransmiter systems that play an important role in depresion.
