Adolescent Idiopathic Scoliosis: Understanding the Immune, Nervous System, and Emotional Connections

A Whole-Person Approach to Scoliosis Care in Southeast Asia

By All Well Scoliosis Centre – Specialist Scoliosis Treatment in Southeast Asia

Introduction: Scoliosis Is More Than a Spinal Curve

Adolescent Idiopathic Scoliosis (AIS) is often described as a spinal condition with no known cause. However, clinical experience and emerging research suggest that scoliosis affects — and is affected by — multiple body systems, including the nervous system, immune regulation, metabolism, and emotional development.

At All Well Scoliosis Centre, we specialise in scoliosis treatment across Southeast Asia using a whole-person, evidence-informed approach — recognising that the spine does not exist in isolation from the brain, body, and emotional well-being.

Is the Immune System Involved in Idiopathic Scoliosis?

AIS is not classified as an autoimmune disease. However, scientific studies increasingly report subtle immune and inflammatory differences in adolescents with idiopathic scoliosis.

What research shows:

  • Transcriptomic studies have identified differences in immune-related gene expression in adolescents with scoliosis, suggesting immune system modulation rather than immune attack.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC12517965/

  • Genetic studies using Mendelian randomisation suggest that certain inflammatory cytokines may be associated with scoliosis susceptibility, reinforcing the role of systemic signalling pathways.

    https://pubmed.ncbi.nlm.nih.gov/39664590/

What this means clinically

Immune regulation — including the activity of regulatory T cells (Tregs) — may influence:

  • Inflammatory balance

  • Growth signalling

  • Stress adaptation

However, no current evidence supports immune dysfunction as the sole cause of scoliosis. Instead, immune activity appears to be one contributing factor within a broader biological system.

The Nervous System: A Key Missing Link in Scoliosis Care

One of the most consistent findings in AIS research is altered nervous system regulation, particularly involving the autonomic nervous system (ANS).

Studies have demonstrated:

  • Differences in sympathetic–parasympathetic balance

  • Altered heart rate variability (HRV)

  • Changes in sensory integration and proprioception

👉 PubMed – Autonomic nervous system function in AIS

https://pubmed.ncbi.nlm.nih.gov/15455999/

👉 BMC Neuroscience – Sensory integration in AIS

https://bmcneurosci.biomedcentral.com/articles/10.1186/1471-2202-7-68

Why this matters

The autonomic nervous system influences:

  • Appetite and digestion

  • Sleep quality

  • Emotional regulation

  • Immune tolerance

  • Muscle tone and postural control

When regulation is disrupted, adolescents may experience heightened stress sensitivity, reduced appetite, fatigue, and emotional volatility, even when spinal curves appear mild.

Low BMI, Appetite Changes, and Growth Patterns in AIS

Lower body mass index (BMI) is one of the most consistently reported characteristics in adolescents with idiopathic scoliosis.

Research shows:

  • AIS patients often have lower BMI and lean body mass

  • Reduced bone mineral density compared to peers

  • Increased association with disordered eating behaviours — often unintentional and stress-related

👉 PubMed – BMI and body composition in AIS

https://pubmed.ncbi.nlm.nih.gov/38505221/

At All Well Scoliosis Centre, we emphasise that:

Low appetite and thin body type are not character flaws or poor discipline, but often reflect neuro-metabolic differences during growth.

Emotional Health and Self-Esteem in Adolescents with Scoliosis

Adolescence is a sensitive period for emotional and identity development. Research consistently shows that teenagers with scoliosis may experience:

  • Increased anxiety and mood symptoms

  • Body image dissatisfaction

  • Introversion and internalised stress responses

  • Difficulty accepting diagnosis and treatment

👉 PubMed – Mental health disorders in AIS

https://pubmed.ncbi.nlm.nih.gov/35626775/

👉 Scoliosis Journal – Psychosocial impact of AIS

https://scoliosisjournal.biomedcentral.com/articles/10.1186/s13013-017-0136-9

These emotional responses are biologically understandable when considering:

  • Nervous system sensitivity

  • Hormonal changes during puberty

  • Social pressures and parental stress

  • Altered dopamine signalling under chronic stress

Acceptance is not a personality issue — it is often a regulation issue.

Why a Whole-Person Approach Matters

At All Well Scoliosis Centre, we integrate:

🧠 Nervous System Regulation

  • Breathing and postural control strategies

  • Movement-based rehabilitation to support parasympathetic balance

💪 Structural & Functional Care

  • Evidence-based scoliosis-specific exercises

  • Non-invasive scoliosis management strategies

🥗 Growth & Nutrition Awareness

  • Education for parents on adequate nutrition during growth

  • Avoidance of unnecessary restriction during treatment

🧍 Emotional & Family Support

  • Clear, empowering education for patients

  • Guidance for parents to reduce fear-based monitoring

  • Strength-based language that restores confidence and agency

Conclusion: Treating the Person, Not Just the Curve

Adolescent idiopathic scoliosis reflects a complex interaction between the spine, nervous system, immune regulation, metabolism, and emotional health. While research into immune markers such as regulatory T cells continues to evolve, current evidence supports a multi-system, patient-centred approach.

At All Well Scoliosis Centre, we believe that the most effective scoliosis care in Southeast Asia is one that:

  • Respects science

  • Avoids over-medicalisation

  • Supports growth, resilience, and long-term well-being
