Scientists at Harvard University, have used advanced brain imaging such as PET scans and fMRI scans in order to get a closer look at the inner workings of the brain. Use of this sophisticated technology has led to a better understanding of the extent that brain imbalances have in the manifestation of depression. The areas of the brain that play a significant role in depression are the amygdala, the thalamus, and the hippocampus.
Depression and Brain Imbalances
Researchers at Harvard are trying to connect the dots between the slow production of neurons in the hippocampus part of the brain and feelings of depression. This theory is further supported by how antidepressants work: specialized medication immediately boosts the number of neurotransmitters in the brain, gradually improving the patient’s mood.
However, if depression was exclusively the result of imbalances of brain chemicals, then people would feel better immediately after they were administered medication.
Depression As a Side Effect
Depression can be triggered by a variety of emotional or physical issues. Severe life changes, grief from the death of a loved one, major illnesses can cause depression. There are also individuals with a family history of depression.
Depression is closely linked with anxiety. Some of the factors that can play a significant role in the appearance of depression in one’s life are:
⦁ Physical or emotional abuse
⦁ Medication side-effects
⦁ Grief caused by death or a loss
⦁ Genetic predisposition
⦁ PTSD & Major life events, such as the move to a new city or retirement
⦁ Serious illness
⦁ Substance abuse
