Most people understand the basics of depression. However, it’s much more than a condition that causes you to feel sad. As one of the most commonly diagnosed mental health conditions across the globe, it’s important to understand how depression truly affects the brain. 

The more you understand what depression does to your brain, the more sense the condition might make. For people on the fence about getting a diagnosis or for those who are trying to “ignore” their symptoms, understanding the mechanics behind it can help. 

With that in mind, let’s take a look at three things you should know about how depression affects the brain, and why each of these components makes such an impact.

1. A Shrinking Brain

The idea of your brain “shrinking” doesn’t sound so good, right? Unfortunately, studies have shown that people with depression experience shrinkage in certain areas of the brain – the areas that tend to affect decision-making, concentration and memory, and sleep. 

There’s still more research to be done to pinpoint all areas of the brain depression impacts. However, it’s clear that the biggest areas of brain shrinkage occur in the hippocampus, the prefrontal cortex, and the thalamus.

The hippocampus is responsible for regulating stress hormones. It’s also a crucial component of concentration and memory. As it starts to shrink, not only does it become more difficult to focus, but excess stress can start to feel overwhelming. 

The prefrontal cortex is the area of your brain used for problem-solving and making decisions. When it shrinks, you’ll be more prone to acting on impulse. It will also be easier to become irritated and frustrated. 

The thalamus is responsible for regulating sleep. Multiple studies have showcased the important connection between depression and sleep. If you’re not getting the rest your mind and body need, your feelings of hopelessness and helplessness often get worse.

2. Inflammation

It might seem contradictory to think that your brain is shrinking and inflamed at the same time. However, clinical depression often causes inflammation in a different part of the brain – the amygdala. 

This is essentially the “fight or flight” area of your brain. When it is enlarged during a depressed state, you’re more likely to feel anxious, restless, sad, or even guilty. 

Your thinking can become fuzzy, and you’re less likely to naturally make serotonin, making it harder to feel happy when you’re in a depressed episode.

3. Reduced Oxygen

This is, perhaps, the most serious and important thing that happens in the brain when you’re clinically depressed. 

Everyone knows the body and brain need oxygen to function properly. Unfortunately, when you’re struggling with depression, your brain might not get the levels of oxygen it needs. 

At first, that can lead to issues like

• Difficulty paying attention

• Memory loss

• An inability to move properly

However, the longer you’re in a depressed state, the more serious the potential consequences become. If your brain goes without enough oxygen for too long, it can lead to seizures, and may even trigger a coma. 

These pictures of how depression affects the brain aren’t meant to scare anyone. It’s an important reality to understand, so those with depression can get properly diagnosed and treated. 

In fact, that’s the good news. Depression is typically very manageable and treatable with the right support and guidance. You don’t have to put your mind, body, or life in general through these things forever.
