Charcot-Marie-Tooth disease (CMT) is the most common inherited neuromuscular disorder, affecting an estimated 1 in 2,500 people worldwide. It damages the peripheral nerves that carry signals between the brain and the muscles and sensory organs of the hands and feet, causing slowly progressive muscle weakness, wasting, foot deformities, and loss of sensation that typically begins in childhood or early adulthood and continues, often very gradually, across an entire lifetime. Because CMT rarely shortens life expectancy but reliably erodes physical ability over decades — affecting walking, balance, hand dexterity, and independence — it creates a distinct, long-haul psychological burden that is easy for the outside world to overlook. A 2023 case–control study drawing on Italy's national CMT patient registry set out to measure, for the first time in a large sample, exactly how often that burden shows up as clinically meaningful anxiety and depression.
What the Research Shows
Researchers surveyed 252 people with CMT enrolled in the Italian CMT National Registry, along with 56 healthy controls (mostly patients' relatives and friends), using the well-validated Hospital Anxiety and Depression Scale (HADS). Using the scale's standard cutoff for moderate-to-severe symptoms, 26 of 252 CMT patients (10.3%) screened positive for depression, compared to just 1 of 56 controls (1.8%) — a statistically significant difference. A composite measure of general psychological distress followed the same pattern: 36 patients (14.2%) screened positive, versus 2 controls (3.6%), also significant. Anxiety symptoms were also common — 64 patients, or 25.4%, screened positive, compared to 8 of 56 controls (14.3%) — though with this study's smaller control group, that particular gap did not reach statistical significance. Patients with more severe disease, as measured by a standard CMT disability scale, were significantly more likely to screen positive for depression and general distress, suggesting the disease's physical toll and its psychological toll move together.
Ways to Cope
- Treat gradual functional losses as real losses worth grieving. CMT's slow pace can make each new loss — needing a brace, giving up a sport, losing fine hand dexterity — feel like it shouldn't be a big deal because “it's just more of the same disease,” but each milestone is its own loss and deserves its own space to process.
- Ask for a referral to a physical or occupational therapist who understands CMT specifically. Because CMT is relatively rare, many generalist therapists have little experience with it; a specialist familiar with its particular pattern of distal weakness can suggest bracing, exercises, and adaptive strategies that protect both function and the independence that psychological wellbeing often depends on.
- Connect with other people who have CMT, not just general neuromuscular-disease communities. CMT's specific genetic basis, slow and distal progression pattern, and wide range of severity across subtypes create experiences that can feel different from other neuromuscular conditions; patient organizations built specifically around CMT can offer more precisely relevant peer support.
- Bring up mood directly at neurology or physical therapy appointments, not just physical symptoms. This research found a meaningfully higher rate of both depression and general distress among people with CMT; naming mood changes explicitly, rather than waiting to be asked, makes it far more likely they get addressed rather than overlooked next to more visible physical symptoms.
- Know that it's common to go untreated even when you're struggling. In this same study, about half of patients screening positive for depression or distress were receiving no treatment for it at all; if that sounds familiar, it's a sign to ask for help, not a sign that your experience is unusually severe or unusual.
A Real Signal, With Honest Limitations
This study offers something relatively rare in CMT research: a direct comparison between a sizable patient sample and an actual control group, rather than just a bare, uncontrolled prevalence figure. Its depression and general-distress findings held up as statistically significant despite a modest control group of 56 people. Still, several limitations are worth naming. The control group, drawn mainly from patients' own relatives and friends, was not formally matched for age, sex, or education, and its small size likely left the study underpowered to detect a significant difference in anxiety specifically, even though the raw rate was nearly twice as high in patients (25.4%) as in controls (14.3%). The HADS is a validated screening tool, not a diagnostic interview, so these figures reflect clinically significant symptom levels rather than confirmed psychiatric diagnoses. The study was also cross-sectional and relied on online self-report, which can introduce selection effects and cannot show how symptoms change as the disease progresses. Finally, this is a single national registry from Italy, and rates could differ in other countries or in less digitally engaged patient populations.
You're Not Alone
If you're navigating CMT or another inherited neuromuscular condition, the challenges involved often overlap with ground covered elsewhere on this site. Because CMT shares much with other inherited, progressive neuromuscular diseases, our page on Muscular Dystrophy and Mental Health covers closely related emotional territory. For the broader experience of a long-term physical condition, our guide to Living with Chronic Illness or Pain offers additional coping tools, and because CMT often involves nerve pain or discomfort, our page on Coping with Chronic Pain may also be useful. If CMT's effects on dexterity, stamina, or mobility are affecting your job, our page on Workplace Accommodations for Disability and Chronic Illness can help you think through your options.
Tips for Supporting Someone With CMT
- Don't assume CMT only affects the feet. CMT commonly causes hand weakness, reduced grip strength, and fine-motor difficulty as well as foot and lower-leg symptoms — tasks like buttoning a shirt, opening jars, or writing by hand can be genuinely difficult even when someone can still walk comfortably.
- Recognize that CMT is progressive, even when it moves slowly. Because change often happens over years rather than days, it's easy to assume someone's needs are stable; checking in periodically rather than assuming nothing has changed shows you're paying attention to a disease that keeps evolving.
- Offer specific, practical help rather than a general “let me know if you need anything.” Concrete offers — carrying something heavy, walking at a slower pace on uneven ground, helping open a stubborn jar or bottle — are easier to accept than open-ended offers, especially for someone used to managing independently.
- Ask directly about mood, not just mobility. This research found meaningfully higher rates of both depression and general psychological distress among people with CMT, and about half of those affected weren't getting any treatment; a genuine “How are you holding up with all of this?” can open a door that physical check-ins alone don't.
- Don't minimize CMT because it's “just” a slow-moving condition. The gradual pace of CMT doesn't make its physical and emotional toll smaller — a lifetime of accumulating losses and adaptations can be just as heavy as a more sudden-onset condition, simply spread out differently over time.
