They include muscle loss that leads to balance and walking difficulties, and heart problems. As with the more serious Duchenne muscular dystrophy, the pattern of muscle weakening and wasting commonly begins in the hip and pelvis areas, and then progresses to the thighs and shoulders. What are the symptoms of Becker muscular dystrophy? This type of muscular dystrophy likewise more typically impacts young boys, according to iytmed.com. Studies focusing on skeletal-muscle involvement were done before DNA analysis was possible. Becker muscular dystrophy (BMD), initially described by Becker and Kiener in 1955, is an inherited disease with a male distribution pattern and a clinical picture similar to that of Duchenne muscular dystrophy (DMD). Leg muscles become increasingly weaker. BMD causes weakness of skeletal muscles, breathing muscles, and the heart muscle. Talk to your caregivers, family, or friends about your feelings. In most cases, muscle weakness becomes apparent later in childhood or in adolescence and worsens at a much slower rate. 38 Orthopedic treatment of patients with Becker muscular dystrophy depends on the severity of the disease.

Outside Organization Programs & Information, Cardiac Complications and Management in BMD. Becker muscular dystrophy (BMD) is an inherited muscle-wasting condition primarily affecting boys and men. A 17-year-old male patient who was diagnosed with Becker muscular dystrophy (nonsense mutation [c.3822C>A] within exon 28 of the DMD gene) at 6 years of age was evaluated in the multidisciplinary neuromuscular clinic for loss of ambulation for 1 year. Although both men and women can develop muscular dystrophy, the most common type, called Duchenne, affects young boys primarily. What Is Becker Muscular Dystrophy? Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X-linked recessive disorders caused by mutations in the dystrophin gene. A multidisciplinary team of specialists with experience in treating Becker muscular dystrophy can help address symptoms: Physical and occupational rehabilitation professionals can design exercise programs and teach stretching activities to minimize contractures, which are hardened or deformed joints caused by contracting muscles and tendons. The age of onset varies as well. Becker muscular dystrophy is a muscle-wasting condition, first described in 1956, which usually affects only males. This is a retrospective case series of neurodevelopmental, behavioral, and emotional symptoms and respective pharmacotherapies of 70 patients with BMD. Becker muscular dystrophy signs and symptoms show up in patients during their teens or young adult years. Symptoms usually start in late childhood or early adolescence and affects the lower limbs, in particular the Some people with BMD have mild skeletal muscle involvement but severe cardiac problems. Becker Muscular Dystrophy. Related terms: Duchenne muscular dystrophy is similar to this disease, but BMD tends to have a later onset and slower progression. The signs and symptoms of Becker muscular dystrophy are usually milder and more varied.

Muscle weakness occurs primarily in your arms and legs, with symptoms appearing in between age 11 and 25. Duchenne muscular dystrophy and Becker muscular dystrophy are X-linked recessive disorders characterized by progressive proximal muscle weakness caused by muscle fiber degeneration. Muscle weakness usually becomes apparent between the ages of 5 Eye problems in different types of muscular dystrophies The skeletal muscles controlling the movement of the eyes, also known as extra-ocular muscles, show a normal structure and function in Duchenne and Becker muscular dystrophies . Diagnosis is suggested clinically and is confirmed by genetic testing or analysis of the protein product (dystrophin) of the mutated gene. Symptoms may appear as late as age 25. Duchenne dystrophy Symptoms usually begin between ages 2 and 4. The condition is named for the German physician Peter Emil Becker, who first described this variant of muscular dystrophy in the 1950s. Johns Hopkins Medicine will contact patients as we learn more about distribution plans from government officials. The clinical course of Becker muscular dystrophy is variable. Becker muscular dystrophy (BMD) is an X-linked recessive disorder due to mutation in the Dystrophin gene that results in progressive muscle degeneration and proximal muscle weakness. To compensate for weakening muscles, a person with BMD may walk with a waddling gait, walk on his toes, or stick out his abdomen. Becker MD also progresses slower than DMD and is The disorders differ in which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin.
