In developmental stages a child’s brain can become permanently damaged due to stress levels. The damage is done in receptors in parts of the brain that deal with serotonin, dopamine and cortisol. These 3 chemicals play major roles in the way we interpret and perceive emotional events. Damage to these receptors and unbalancing the levels of these chemicals can cause permanent damage in the parts of our brain that deal with emotions, this can lead to an individual leading a destructive and unhappy life because of the way our interpretations and perceptions are how we navigate our way through our lives. Hypersensitivity, overgeneralizations and misinterpretations can lead to an unsettled life.
One of the most important developmental stages is during the mother’s pregnancy. During foetal development, if the mother is subject to high levels of anxiety and stress, this can cause permanent damage to the emotional centres of the brain of the foetus. Thus leading to a subsequent human with the potential for delinquent tendencies, bouts of depression throughout their lives, anti social behaviour and unfulfilled and destructive relationships.
Also, if the subsequent child suffers high degrees of stress and anxiety in their developmental years, this can also lead to permanent brain alterations in the emotional centres of the brain and the ability to deal with emotional issues and hypersensitivity to incidents causing anxiety and stress. Massive overgeneralization, gross misinterpretations and explosive hysterical episodes would become the norm for this person, leading to a complete inability to have constructive relationships with others.

Other things that can cause an imbalance in the emotional brain are certain drugs that affect the serotonin and dopamine levels, for instance long term regular use of cannabis is well known to cause problems with the serotonin and dopamine levels in some individuals leading to schizophrenia like symptoms. Cannabis use during pregnancy could seriously affect the emotional centres in the brain of the unborn child if the mother is a habitual user and continues during pregnancy.
