Duchenne muscular dystrophy (DMD) is usually recognized between the ages of three and six years.
DMD is a genetic disorder primarily affecting males. It causes progressive muscle weakness and wasting (atrophy). The condition typically becomes noticeable when boys are between three and six years old. The initial signs often involve the muscles of the pelvic area, leading to difficulties with activities such as running, jumping, and climbing stairs. As the disease progresses, the shoulder muscles become affected. This pattern of muscle involvement is characteristic of DMD.
Here's a breakdown of when DMD symptoms typically emerge:
- Early Childhood (3-6 years): This is the most common time for DMD to be diagnosed. Parents and caregivers may notice that the child is developing motor skills slower than their peers, has difficulty keeping up physically, or frequently falls.
- Later Progression: As the boy gets older, muscle weakness increases, impacting mobility and respiratory function.
