Is depression a choice? Well, certainly not as it affects nearly 300 million people all over the world. It is a mental health condition that can affect your brain and health.
Does depression cause brain damage or the other way around? This has been the topic of debate for years and finally, researchers have found evidence that persistent depression leads to brain damage and not vice versa.ย
Neurologists previously hypothesized that brain damage was a predisposing factor for chronic depression, but a new study published in Molecular Psychiatry sheds a different light on the subject.
In a study of 9,000 individual samples collected from the ENIGMA group database, researchers found a causal relationship between persistent depression and brain damage.
Upon comparing theย Magnetic resonance images (MRIs) of participants in study diagnosed with chronic depression (1,728 patients) and healthy individuals (7,199 ), shrinkage of the hippocampus was found in the former.ย ย
Specifically, the study found that those patients diagnosed with major depressive disorder, โshowed robust reductions in hippocampal volume (1.24%) in MDD (Major Depressive Disorder) patients compared with healthy controls.โย

What is the hippocampus?
The hippocampus is a small area of the brain that is located in the medial temporal lobe of the brain.ย ย It is comprised of two halves, one of which resides in each hemisphere of the brain. It plays an important role in the limbic system.
Hippocampus is the region in the brain associated with the creation of new memories and associating emotions with them. Its functionality also involves spatial navigation and the formation of long-term memory.ย
Inside the hippocampus resides the amygdala and its key role is to process and comprehend emotions. This part of the brain is attached to the limbic system too and also functions to connect emotions to memories.ย

According to some studies on the brain and mental health, the amygdala and shrinkage of the hippocampus were linked with depression, but due to limitations like small sample size, the results are not quite reliable.ย
The hippocampus and depression
Researchers have found that in addition to its importance in forming and maintaining memories, the hippocampus is also pivotal in controlling emotions.ย
Professor Ian Hickie, a co-author of the study and a renowned mental health campaigner,ย explainsย the hippocampusโ relationship to depression,ย โYour whole sense of self depends on continuously understanding who you are in the world โ your state of memory is not about just knowing how to do Sudoku or remembering your password โ itโs the whole concept we hold of ourselvesโ
Professor Hickie further elaborates on the relationship between a shrinkage in the hippocampus and changes in behavior observed inย animals fromย the past, โWeโve seen in a lot of other animal experiments that when you shrink the hippocampus, you donโt just change memory, you change all sorts of other behaviors associated with that โ so shrinkage is associated with a loss of function.โ
Those who suffer from depression usually have low self-esteem and lack motivation in completing even day-to-day self-care activities like bathing, eating, combing oneโs hair, or dressing. It is common for those suffering from depression to also have a deflated self-confidence, which simply refers to their negatively distorted self-image.
Consequently, it affects the process of creation and storage of memories, your perception of your past self, and how you project yourself in the future.ย
What is depression?
Depression is a mental health disorder (a type of mood disorder) characterized by persistently depressed or low mood or a complete loss of interest in activities causing significant impairment in daily activities.
People living with depression are pessimistic about their relationships, work, careers, and everything in life. And the root is low self-esteem and negative perceptions about themselves and the people around them.ย
The state of depression manifests through repetitively regretting your past and fearing the future and this is known as rumination. It is not a singular conscious choice. Thoughts and feelings are well connected. As you think, so shall you feel!
When you think negatively your brain fantasizes about uncomfortable and unpleasant outcomes and vice versa when you think positively. In the case of people with depression, their mind is filled with a pessimistic outlook toward life.

The outcome of repetitive negative thoughts is cognitive restructuring where your brain alters your emotional reactions and behaviors toward unfavorable outcomes. Sort of how an avalanche only goes faster and gets bigger when careening down a snow-covered mountain.
Some interesting statistics are available supporting the shrinkage of the hippocampus based on which researchers argue that such shrinkage parallels the change in the thinking process of people with depression.ย
But, the important question is if it is difficult for someone with even a small percentage of reduction in the hippocampus to overcome negative thinking without the full capacity of their brain.ย
