There are a number of deficiencies/imbalances that underlie psychiatric disorders. Let’s just think about the imbalance in the immune system (such as the imbalance in various types of white blood cells, the immune system that attacks the body (autoimmunity), or an overactive immune system), an hormonal imbalance, a deficiency in omega-3 fatty acids, a lack of certain vitamins (for instance vitamin E), increased oxidative stress, decreased antioxidative capacity (for instance decreased zinc concentration in the blood) or an imbalance between various trace elements.

Further on, a number of instigating factors can, depending on the individual, trigger a disease: viral/bacterial infections, food allergies, nutritional deficiencies and psychological stress.

Moreover, a number of known genetic factors make people more susceptible to certain disorders (for instance genetic abnormalities in the serotonin system (serotonin is a messenger substance in the nerves) or congenital abnormalities of the immune system).
