Early Symptoms of Duchenne Muscular Dystrophy
Recognizing the early symptoms of Duchenne Muscular Dystrophy (DMD) plays a critical role in the timely diagnosis and management of this progressive neuromuscular disorder. While the signs may vary from person to person, several common indicators can alert parents and healthcare professionals to the possibility of DMD.
Delayed motor milestones:
Children with DMD often experience delays in meeting standard motor milestones such as sitting, crawling, and walking. Parents may notice that their child is slower to reach these developmental milestones compared to their peers.
Muscle weakness:
One of the hallmark symptoms of DMD is muscle weakness that becomes more evident over time. Initially, parents may notice that their child has difficulty getting up from the floor, climbing stairs, or carrying heavy objects.
Difficulty walking:
As DMD progresses, walking becomes more challenging for affected individuals. They may develop a waddling gait, experience frequent falls, or demonstrate an unusual pattern of toe-walking.
While these early symptoms may not be exclusive to DMD and can be attributed to other conditions or developmental variations, it is crucial to seek medical evaluation if any of these signs are present. Early diagnosis allows for timely intervention and access to necessary treatments and support.
Diagnosis of Duchenne Muscular Dystrophy
