The diagnosis of muscular dystrophy is based on the results of muscle biopsy, increased creatine phosphokinase (CpK3), electromyography, and genetic testing. A physical examination and the patient's medical history will help the doctor determine the type of muscular dystrophy.
Screening can detect problems such as neural tube defects, chromosome abnormalities, and gene mutations that would lead to genetic disorders and birth defects such as spina bifida, cleft palate, Down syndrome, trisomy 18, Tay–Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, muscular dystrophy, and fragile X syndrome.
For the diagnosis of congenital muscular dystrophy, the following tests/exams are done: [2] Lab study (CK levels) Muscle MRI and especially whole body muscle MRI has recently been used to describe muscle abnormalities in patients with primary laminin-α2 (merosin) deficiency subtype of CMD. EMG; Genetic testing
Distal muscular dystrophy, also called distal myopathy, is essentially any muscle disease that preferentially affects the hands and/or feet, a much less common pattern than proximal muscle weakness. Late adult-onset type 1; Late adult-onset type 2a; Late adult-onset type 2b; Early adult-onset type 1; Early adult-onset type 2; Early adult-onset ...
[9] [10] Babies of mothers with myasthenia may have symptoms during their first few months of life, known as neonatal myasthenia [1] or more specifically transient neonatal myasthenia gravis. [11] Diagnosis can be supported by blood tests for specific antibodies, the edrophonium test, electromyography (EMG), or a nerve conduction study. [1]
Emery–Dreifuss muscular dystrophy (EDMD) is a type of muscular dystrophy, a group of heritable diseases that cause progressive impairment of muscles. EDMD affects muscles used for movement (skeletal muscles), causing atrophy, weakness, and contractures. It almost always affects the heart, causing abnormal rhythms, heart failure, or sudden ...
Duchenne muscular dystrophy Gowers's sign is a medical sign that indicates weakness of the proximal muscles , namely those of the lower limb . The sign describes a patient that has to use their hands and arms to "walk" up their own body from a squatting position due to lack of hip and thigh muscle strength.
The symptoms of exercise intolerance, abnormal muscle fatigue, myalgia (muscle pain), arrhythmia, possible fixed proximal muscle weakness, lipid deposits, possible episodes of rhabdomyolysis, with symptoms becoming evident or worsening while fasting, during a fever, during low-intensity aerobic activity or after prolonged activity–all these ...
