Western medicine has treated the mind and body as separate entities for centuries. Physical ailments were treated with surgeries and medications, while mental illnesses were often dismissed or treated in isolation. However, groundbreaking research proves this division is flawed and may prevent millions from receiving the best care.
New insights from neuroscience, immunology, and psychology reveal that every physical or mental illness combines both. Understanding this connection could revolutionize healthcare and provide better treatments for conditions ranging from chronic pain to depression and autoimmune diseases.
The Mind’s Hidden Role in Physical Health
Camilla Nord, a neuroscientist at the University of Cambridge, experienced firsthand how the brain influences physical illness. After a persistent foot injury, doctors recommended joint replacement but first injected steroids to delay surgery. Though steroids wore off, her pain remained significantly reduced nearly a decade later.
Nord realized this wasn’t just luck—chronic pain rewires the brain, amplifying pain signals even after healing. The temporary relief may have disrupted this cycle, allowing her brain to “reset” its pain processing. This highlights neuroplasticity—the brain’s ability to rewire itself—suggesting that pain, once learned, can also be unlearned, opening doors to new treatments.
Why Our Healthcare System is Failing Patients
Despite growing evidence of the mind-body connection, the medical system remains divided. Mental and physical health services often have separate budgets, different specialists, and even separate buildings. This has serious consequences:
People with mental illnesses are less likely to receive screenings, proper treatment, or follow-up care.
In the absence of structural damage in the body, patients with chronic illnesses - such as Functional Neurological Disorder (FND) - are often misunderstood, dismissed, or told it’s “all in their head.”
When physical and mental symptoms are treated separately, chronic pain may be treated with painkillers instead of addressing the brain’s role in sustaining it, and immune system dysfunction may be overlooked as purely physical when stress and trauma play significant roles.
By treating the mind and body separately, we may be making people sicker than they need to be.
How Your Brain Predicts and Creates Symptoms
One of the most exciting developments in neuroscience is the idea that the brain is a “prediction machine.” Rather than simply reacting to the world, it constantly predicts what will happen next—and those predictions can shape our physical experiences. This ties into Dr. Howard Schubiner's Predictive Coding's inherent role in the "chronification" of symptoms.
For instance:
Pain and illness can be conditioned: Studies show that people can learn to experience pain, nausea, or even allergic reactions simply by association. In a famous experiment, rats given sugar water laced with toxins became so conditioned to feeling sick that they later fell ill from plain sugar water—even though it contained no toxins.
The placebo and nocebo effects: If someone believes a treatment will work, their brain can trigger accurate healing responses, such as releasing endorphins and reducing inflammation. Conversely, if they expect to feel worse, their symptoms can intensify—a phenomenon known as the nocebo effect.
Stress and trauma affect immunity: The immune system doesn’t distinguish between physical threats (like bacteria) and mental ones (like emotional distress). Studies show that inflammation—a key driver of many chronic diseases—can be triggered by social stress, trauma, and even loneliness.
This means that chronic conditions like fibromyalgia, irritable bowel syndrome, back pain, and autoimmune diseases may be worsened by psychological factors, making mind-body treatments a crucial part of healing.
Rethinking Treatment: New Approaches to Health
Retraining the brain could be a powerful treatment if the brain plays a role in physical illness. Emerging therapies are already showing promise:
Pain Recovery Coaching: Chronic pain is increasingly understood as a brain-based condition that can be influenced by fear, stress, and learned pain pathways. Pain recovery coaching helps individuals retrain their nervous system, shift their mindset, and develop strategies to reduce or eliminate chronic pain symptoms.
Cognitive Behavioral Therapy (CBT) for chronic illness: While often associated with mental health, CBT has been shown to improve symptoms of irritable bowel syndrome (IBS), chronic pain, and even heart disease by changing how patients perceive and respond to symptoms.
Interoception training: Many people with anxiety and depression have difficulty accurately sensing their internal states. Training them to detect their heart rate and bodily signals better has been shown to reduce anxiety in clinical trials—sometimes with long-lasting effects.
Transcranial Magnetic Stimulation (TMS): A non-invasive treatment that stimulates brain regions involved in depression, OCD, and even chronic pain. It disrupts negative thought and pain patterns, helping the brain reset.
