How Does Chronic Pain Affect the Brain? Revealing Report

Thursday, February 4, 2021

Chronic pain is no joke. It can be completely debilitating and, even worse, might not be taken seriously enough by friends and family.

Did you know? Chronic pain can actually change the makeup of your brain. It's true - there's a reason why chronic pain can make you feel totally hopeless and unlike your normal self.

Here, we're taking a closer look at chronic pain, how chronic pain affects the brain, and how physiotherapy can help with your chronic back pain or other forms of chronic pain.

What is acute pain and chronic pain?

How Does Chronic Pain Affect the Brain?

Acute pain refers to short-term pain that eventually heals. Acute pain might be associated with a broken arm or an ankle injury. Yes, you'll feel pain. But once the proper measures are taken, that pain eventually subsides and you can go back to your regular activities.

Chronic pain, on the other hand, is long-term pain that can last months or even years. It's usually caused by inflammation or nerve issues and requires regular treatment.

Those without chronic pain might not realise the toll it can take. Not only is it absolutely miserable to be in constant pain, but it also quite literally affects the brain.

Plus, the financial requirements of regular treatments can also cause a lot of stress, creating a feedback loop of pain and anxiety.

To better understand what's actually going on with a person experiencing chronic pain, let's have a look at how chronic pain affects the brain.

How does chronic pain affect the brain?

Research suggests that the brain perceives long-term pain differently than it perceives short-term pain.

One study found that when we experience acute pain, our thalamus opens, connecting the spinal cord with the higher centers of the brain. The thalamus allows information to pass about the acute pain, helping us to heal and recover.

However, when acute pain changes to chronic pain, the thalamus remains open long after the acute pain subsides. From there, the size of the thalamus decreases resulting in a decrease of the neurotransmitter called GABA.

With less GABA and the thalamus pathway wide open, it causes us to perceive pain more intensely since every signal in our brains is being fired, amplifying our experience of pain.

Chronic pain can actually change the central nervous system and influence our sensory, emotional, and modular circuits that normally help us manage pain. Basically, our CNS (Central Nervous System) is amplifying our perceived pain when we experience it for too long.

It's why people with chronic pain can seem like they're exaggerating their symptoms when, in reality, the brain is sending different signals than it sends to someone experiencing acute pain.

In short, chronic pain could be considered a neurological disease depending on how you look at it. Chronic pain, therefore, is often related to depression and anxiety due to these altered neurological and cognitive effects.

So, dealing with chronic pain means dealing not only with the physical sensations themselves but also the neurological damage that has been done as a result.

Psychologic Effects of Chronic Pain

Aside from the ways chronic pain affects the brain, chronic pain can also affect some other areas of our psychological health.

Chronic Pain Affects Our Mood

Since chronic pain can affect our emotional centers, it can cause our moods to swing widely. These changes might also cause someone to seek help from anti-anxiety and anti-depression medications, which can further affect one's mood.

However, as one can imagine, chronic pain is likely to make a person feel helpless, frustrated, and scared, wondering whether the pain will ever subside. It's not surprising that all of these effects compound.

Chronic Pain Affects Our Relationships

From physical limitations to emotional effects, chronic pain can do a number on our relationships. Whether you're less empathetic to your spouse or you stay home instead of socialising due to your chronic pain, it can certainly have a negative effect on every relationship in your life.

Since strong relationships are essential to strong mental health, when your relationships suffer, it puts further strain on our psychological well-being. Just another way chronic pain can affect our brain.

How Does Chronic Pain Affect the Brain?

Chronic Pain Affects Our Personality

One study found that chronic pain creates smaller amounts of glutamate in the brain. Glutamate the brain's key chemical messenger that regulates thoughts and emotions.

These lowered glutamate levels caused a disruption in the communication of brain cells causing negative personality changes including more negative, fearful, and pessimistic thoughts. In short, chronic pain can actually change our personality.

Chronic Pain Affects Our Sleep

Sleep is crucial to our overall health and well-being. As you might predict, dealing with relentless chronic pain makes it difficult to sleep uninterrupted. Poor sleep can cause immune system issues and further negatively affects our mood.

We have less self-control when we lack sleep and therefore can exacerbate chronic pain even further. Poor sleep is then not only a symptom of chronic pain but can also become a cause.

Chronic Pain Affects Our Memory and Focus

Not only does chronic pain affect our emotional state, but it can also interfere with our memory pathways. So, when dealing with chronic pain, we might also notice our ability to remember information is slipping.

Plus, these pathways also manage our ability to concentrate in the moment, making it difficult to work or study.

These issues only further cause feelings of frustration and helplessness, all working together in a feedback loop of struggle.
