Duchenne Muscular Dystrophy: Symptoms, Causes, Treatment
حثل دوشين العضلي
Duchenne muscular dystrophy causes progressive muscle weakness, usually beginning in childhood in boys. Early diagnosis and neurological, cardiac and respiratory follow-up matter; enlarged calves do not mean stronger muscles.
What is Duchenne Muscular Dystrophy?
A protein protecting muscle fibers is affected, leading to progressive weakness and possible heart or breathing involvement. Progression and needs vary. Rehabilitation and mobility aids support independence and participation.

Symptoms
Delayed walking, frequent falls, trouble running or climbing stairs and using the hands to rise from the floor may occur. These findings need assessment rather than being dismissed as laziness.
Causes
The disorder results from a dystrophin-gene variant on the X chromosome, inherited or newly arising. Some female carriers develop muscle or cardiac manifestations and need appropriate assessment.
Risk factors
X-linked inheritance makes males more commonly affected, but absence of family history does not exclude the disorder. Genetic counseling guides assessment of relatives and reproductive options without assuming they are affected.
Diagnosis
Evaluation includes neurological examination, muscle-enzyme testing and dystrophin-gene analysis. Additional investigations may clarify the diagnosis and treatment eligibility, with baseline cardiac and respiratory assessment.
Treatment
Care combines rehabilitation, cardiac and respiratory management and specialist-selected medicines. Mutation-directed or gene therapies do not suit every variant or disease stage. The US Elevidys indication was restricted to selected ambulatory patients with a serious liver-injury warning; current eligibility and local availability require verification.
Complications
Complications may include contractures, scoliosis, cardiomyopathy, respiratory weakness and bone problems. Care also addresses learning, nutrition and mental health rather than focusing on muscles alone.
Prevention
Follow-up, stretching, suitable activity and team-advised vaccination help reduce complications. Do not abruptly stop long-term steroids. Inform the anesthesia team of the diagnosis and medicines before any procedure.
When to see a doctor
Arrange early assessment for delayed motor milestones or increasing weakness. Breathing difficulty, choking, chest pain or fainting requires urgent care. Report jaundice, vomiting or deterioration promptly after a new treatment.
