Just a decade or so ago, the adult human brain was thought to be a largely "finished" structure — formed once and relatively unchangeable. Today we know that's not true. The brain is dynamic. Plastic. Sensitive to how we live.
One of the most powerful stimuli affecting its function is... movement.
Research shows that regular physical activity:
- Increases BDNF levels (brain-derived neurotrophic factor)
- Improves neuroplasticity
- Regulates neurotransmitter balance (serotonin, dopamine, noradrenaline)
- Reduces chronic inflammation
- Improves stress axis function
Dr. Joanna Wojsiat, a researcher specializing in neurobiology and neurodegenerative processes, has repeatedly emphasized in her analyses that physical activity is one of the most effective non-pharmacological factors supporting nervous system function. She points out that movement acts as a "biological regulator" — it improves communication between neurons, increases their resistance to damage, and supports repair processes.
This is not a metaphor. This is physiology.
A brain in motion produces more substances that support its regeneration. Proinflammatory activity decreases, microcirculation improves, and the capacity to adapt to stress grows.
Now imagine the reverse situation:
- Chronic pain
- Limited activity
- Isolation
- Sleep disturbances
...which is everything we deal with daily in trigeminal neuralgia and painful trigeminal neuropathy.
This is an environment that favors depression.
When the nervous system suffers — the whole person suffers
Trigeminal neuralgia and painful trigeminal neuropathy are examples of conditions where the disorder affects a specific structure — cranial nerve V. However, the consequences extend far beyond the nerve itself.
Chronic pain:
- Increases cortisol levels
- Disrupts neurotransmitter balance
- Intensifies the inflammatory response
- Lowers BDNF levels
These mechanisms are shared between chronic pain and depression.
That is why their co-occurrence is so frequently observed in clinical practice.
The trigeminal nerve is responsible for sensation in the face. When it functions normally, we don't think about it. When it becomes diseased, every touch can become a challenge.
Trigeminal neuralgia:
Paroxysmal, sharp, "electric" pain lasting seconds but of enormous intensity. Often triggered by everyday activities — speaking, eating, washing the face. Most commonly results from neurovascular conflict and demyelination of sensory fibers.
Painful trigeminal neuropathy:
More constant, burning pain, often with accompanying sensory disturbances. May follow trauma, surgery, or infection.
In both cases, we are dealing with a chronic disruption of nervous system function.
Depression — a biological and psychological companion
Research on chronic diseases shows that individuals with such conditions have a risk of developing depression that is several times higher than in the general population.
Why?
Because chronic pain:
- Limits movement
- Disrupts sleep
- Reduces social contacts
- Undermines the sense of agency
From a neurobiological perspective, there is:
- Stress axis dysregulation
- Decreased serotonin and noradrenaline
- Increased proinflammatory cytokines
- Weakened brain plasticity
These are exactly the mechanisms that physical activity can modulate.
Movement as therapy — real evidence
In large analyses involving individuals with chronic diseases, it was shown that:
- Aerobic exercise clearly reduces depressive symptoms
- A "dose-response" relationship exists (the more weekly movement, the greater the reduction in depressive symptoms — improvement builds gradually with increasing activity)
- Clinically meaningful improvement was observed at approximately 405 MET-minutes per week, slightly below standard WHO recommendations
- Even moderate amounts of movement produce clinically significant improvement
This is especially important for patients with trigeminal neuralgia and neuropathy, whose functional capacity is often reduced.
What this means in practice
This is not about intense training or meeting athletic standards. In chronic pain, what matters most is movement that is regular, gentle, and adapted to current capabilities. It might be 5–15 minutes of slow walking per day, a short walk around the house, or gentle exercises done in a safe, comfortable environment.
Consistency matters, not speed or distance. Over time, if the body allows, activity can be very gradually increased — by a few minutes, by a slight change in intensity. Small steps truly make a difference.
It's also worth remembering that chronic pain often goes hand in hand with low mood. That is not weakness or "lack of resilience" — it's a biological response of the body.
That is why it's so important for a treatment plan to also address mental health. Movement doesn't just work on muscles and joints — it directly affects the brain, improves neurotransmitter regulation, reduces inflammation, and supports repair processes in the nervous system. Understanding these mechanisms can help you see physical activity not as an obligation, but as a component of therapy.
Treating pain is not just about reducing a symptom — it's about caring for the whole person. And regular, body-friendly movement can become one of the pillars of that path.
The person, not just the nerve
Trigeminal neuralgia and painful trigeminal neuropathy are not exclusively anatomical problems. They are disorders that affect entire brain function — emotional, cognitive, and social.
Movement will not replace pharmacological or procedural treatment.
But it can become biological support for the brain — a counterweight to chronic pain.
Dr. Wojsiat emphasizes that the brain is a structure that responds to lifestyle just as powerfully as it does to pharmacotherapy. That is an important message for modern medicine.
When the face hurts — it's a sign that a damaged or hypersensitive nerve is sending abnormal signals.
When we stop moving — the brain loses one of its most important tools for regulating pain and mood.
And when we start moving — we activate biological mechanisms that support regeneration and restore balance.

Frequently Asked Questions
What is trigeminal neuralgia?
Trigeminal neuralgia is a chronic facial pain condition. It manifests as sudden, severe, usually one-sided pain attacks — often described as an electric shock. A single attack typically lasts from a few seconds to about two minutes.
What is the difference between neuralgia and neuropathy?
In simple terms: neuralgia primarily involves paroxysmal pain along a nerve, usually without loss of sensation. Neuropathy involves nerve damage that more often causes constant pain along with numbness and sensory loss.
What is neurovascular conflict (vascular compression)?
This is the most common cause of classical trigeminal neuralgia — a blood vessel compresses the nerve root at the base of the brain, damaging its myelin sheath and triggering pain.
Does alpha-lipoic acid (ALA) help with neuropathy?
Some people use ALA as a supportive supplement, but evidence is limited and comes mainly from studies on diabetic neuropathy. It is considered a supplement, not a proven therapy. Always consult your doctor.
Can trigeminal neuralgia be cured?
In many people, pain can be effectively controlled with medications or procedures, and MVD provides the most durable results in eligible patients. The course varies — with periods of remission and relapse. Decisions are made together with your doctor.
