Depression is a complex disease that can be caused by a number of factors including chemical imbalances in the medical conditions of the brain where we examine how the world affects our brains and ourselves our brain imaging studies show that depression is linked to changes in a few parts of the body in the brain especially in the three main area.
1. First is the amygdala which controls emotions such as the joy of anger and fear when a person is depressed the amygdala can be extremely potentially responsible for sleep and behavioral problems and the balance of the main emotional hormones.
2. Second place is the hippocampus processing memory and regulating stress hormones such as cortisol one study found that up to 13% of young and depressed women and excessive cortisol can impair the growth of new neurons that create a negative mood and memory.
3. Third major thalamus that helps coordinate sensory information and adverse conditions in the thalamus may be associated with conditions such as bipolar changes in these parts of the brain and others contaminate important hormones such as serotonin which regulates sleep and air and norepinephrine which stimulates motivation in some depressed people especially if it is caused by a traumatic event but for those with ongoing clinical depression it may take time to find effective treatment statistics showing that adherence to treatment is worth one study conducted by the National Institutes of Health showed 80% of people who improved in four to six weeks of treatment or support groups.
A healthy lifestyle can help – eating a healthy diet and getting enough sleep can strengthen and repair important brain connections to overcome stress. It may be easier in the future to help someone with depression.
