What part of the brain is affected by depression?

What are the basic symptoms of depression? What causes depression chemically? The Effects of Depression on the Brain. Medically reviewed by Timothy J. Depression is a mood disorder that affects the way you think, feel, and behave.

It causes feelings of sadness or hopelessness that can last anywhere from a few days to a few years. When it comes to depression, the brain’s hippocampus, prefrontal cortex and amygdala are involved.

Located near the brain’s center, the hippocampus regulates the hormone cortisol. Cortisol is released during physical and mental stress and depression. Complications occur when extreme amounts of cortisol end up in the brain after such stress. For those interested in learning more about how depression can affect the physical brain , and ways to potentially. Chronic stress can be important in the development of depression.

An inability to cope with stress causes changes in how the brain balances positive and negative information. Depression can literally change your brain, altering the neural pathways and synapses and shrinking the size of your hippocampus , an area of the brain that regulates emotions and memory. Mentally, you probably feel foggy and exhauste as your brain must work harder to process information and feelings.

Regional brain imaging studies have investigated abnormalities in each of these brain subdivisions to investigate the location of depression in the brain. Cortical abnormalities Cortical brain areas implicated in depression are the dorsal and medial prefrontal cortex, the dorsal and ventral anterior cingulate cortex , the orbital frontal cortex and the insula. Depression can damage the brain People suffering from depression run the risk that their brains shrink and will remain smaller after the disease is over. The discovery provides new knowledge about the brain and new understanding of how antidepressants work.

This was the major finding of a study from Sichuan University in Chengdu in China, which features this week at the annual meeting of the Radiological Society of North America in Chicago, IL. Talk to someone now: text us for confidential support. An Expert Will Answer in Minutes!

That’s according to a first-of-its-kind study showing evidence of lasting biological changes in the brain. Using brain magnetic resonance imaging (MRI) data of nearly 9people from around the worl an international team of researchers found that those who suffered recurring bouts of depression also had a smaller hippocampus. This applied to about percent of all depressed participants. The hippocampus is an area in the centre of the brain that is responsible for forming new memories and regulates the production of the hormone cortisol.

The hippocampus is well known to be important in memory as it processes memories for long term storage. Here are a few examples: 1. It’s simply that the particular tuning of neural circuits creates the tendency toward a pattern of depression.
