Adult Care in Duchenne Muscular Dystrophy

Adult care in Duchenne muscular dystrophy is the part of the disease that used to barely exist and now defines its trajectory. With non-invasive ventilation, cardiac medications, and modern multidisciplinary care, life expectancy in Duchenne muscular dystrophy has shifted from a teenage horizon to a population of adults living into their late twenties, thirties, and beyond. That population needs adult-specific care, and the systems to deliver it are still catching up.

This post is a practical overview of what ongoing adult DMD care looks like. The actual plan belongs to the adult care team.

Why adult DMD care is different

Most clinical guidelines, infrastructure, and trained clinicians for DMD were built around the pediatric trajectory. Pediatric neuromuscular clinics, pediatric cardiology, and pediatric pulmonology are common; adult equivalents are rarer. Many adults with DMD end up patched into general adult services that have never seen the disease before.

The 2018 international care considerations explicitly extended to lifelong care, but the implementation gap is real. (Birnkrant et al., Lancet Neurology 2018, Part 2)

Cardiac care in adults with DMD

Cardiomyopathy is the dominant survival concern once respiratory support is established. As ventilation extends life, the heart becomes the leading determinant of outcome.

Adult cardiac care for DMD usually includes:

• Echocardiography or cardiac MRI at intervals matched to disease stage.
• ACE inhibitors and beta-blockers, often started before symptoms appear.
• Mineralocorticoid receptor antagonists in selected cases.
• Heart-failure management when systolic function declines.
• Antiarrhythmic strategies and device discussions when indicated.

Cardiac causes of death have grown as a proportion of overall mortality as respiratory support has improved survival. The implication is straightforward: cardiac surveillance and treatment must continue and often intensify in adulthood. (Cardiorespiratory management of DMD, ScienceDirect)

Respiratory care in adults

Most adult patients with DMD use non-invasive ventilation at night, and many extend ventilation into the day over time. The pulmonologist remains one of the most active members of the care team in adulthood.

Routine elements include:

• Periodic pulmonary function testing (vital capacity, peak cough flow).
• Sleep studies as ventilation needs evolve.
• Equipment optimization (interface fit, settings, backup batteries).
• Cough-assist training and infection-prevention planning.
• Vaccination updates, particularly for influenza, COVID-19, and pneumococcal disease.

A cohort study of adults with DMD treated with glucocorticoids documented broad preservation of respiratory and cardiac function compared with historical controls, though substantial variability remains between individuals.

Endocrine, bone, and metabolic care

Adults who have been on long-term corticosteroids carry a measurable load of endocrine and skeletal effects: short stature, delayed puberty, ongoing adrenal suppression, low bone density, and metabolic considerations. Adult endocrinology with neuromuscular experience is often hard to find and worth the effort.

Rehabilitation, equipment, and mobility

Adult rehabilitation needs continue and shift. Power-wheelchair seating, transfers, contracture management, and assistive technology require ongoing reassessment.

For background, see physical therapy in DMD, choosing a wheelchair in DMD, and assistive technology for communication and daily life in DMD.

Nutrition, swallowing, and bowel care

Swallowing changes and gastrointestinal motility issues become more prominent in adulthood. Some adults transition to gastrostomy feeding for safety and adequacy of intake.

For background, see nutrition in DMD, speech and language therapy in DMD, and bowel and bladder care in DMD.

Mental health and psychosocial care

Adult patients with DMD live with chronic disease, dependence on others for daily activities, and the complicated psychology of having outlived initial expectations. Anxiety, depression, and adjustment concerns are common, and they coexist with caregivers facing their own load.

Adult mental health support is part of standard care, not an extra. For background, see mental health in DMD and caregiver burnout in DMD families.

Education, employment, and autonomy

Adult patients often want and pursue education, work, relationships, and independent living to the degree their function and resources allow. Patient organizations report that this part of life is undersupported by health systems, with the result that families do much of this work themselves.

A UK perspective on adult DMD care described attendance at specialized adult clinics as associated with more frequent cardiac and respiratory assessment in line with international best practice, suggesting that where adult services exist and patients access them, outcomes follow. (Adult care for DMD in the UK, PMC)

Finding adult care

Practical strategies families and patients can use to assemble an adult care team:

• Ask the pediatric team for direct introductions to adult cardiology, pulmonology, and neurology with neuromuscular experience.
• Look for clinics affiliated with major neuromuscular centers, even if travel is required.
• Use patient organizations (Parent Project Muscular Dystrophy, Muscular Dystrophy Association, Duchenne UK, CureDuchenne) to locate adult-DMD-experienced clinicians by region.
• Document the care plan in writing, in a form the patient can hand to a new clinician on a first visit.

For background, see the DMD care team explained.

What is still uncertain

The optimal frequency of cardiac and pulmonary assessment in stable adults, the role of newer disease-modifying therapies in changing long-term outcomes, and the right structure for adult DMD services in countries without dedicated clinics all continue to evolve.

The reasonable framing is that adult care in DMD is now standard, not exceptional, and that the limiting factor in many places is access rather than evidence. The decisions belong to the patient, family, and adult care team.
