The presence of serotonin in depressed levels has often been associated with both depression, violence and compulsive obsessive disorders (Field, 2002). Empirical studies have indicated that those suffering from depression, compulsive obsessive disorders or prone to aggression all have lower levels of serotonin that normal (Field, 2002). The correlation appears to be well evidenced. However correlation does not indicate causation, although this does appear to be the dominant paradigm with the indication that depression is a result of the imbalance of serotonin, which may be combined with environmental factors (Field, 2002). Looking at the first of the independent studies that looks at the role of serotonin levels the causal link between depression and serotonin may be brought into question and then looking at the second study, the results form the first, which indicate an important genetic link are supported with the different function and the relationship it also has to genetic inheritance. The first study was published in 2002; A Longitudinal Study of Serotonergic Function in Depression, published in Neuropsychopharmacology by Robert N Golden et al. This was a primary research article that looked at the manifestation of serotonin and the abnormal neuroendocrine results in serotonergic challenge tests with depressed patients (Golden et al, 2002).
