Several forms of inherited muscular dystrophy are associated with brain abnormalities and cognitive impairment. One of the most common and severe of these diseases is Duchenne muscular dystrophy (DMD). Dystrophin, the product of the DMD gene, is found in neurones, where it is associated with the postsynaptic membrane. Cognitive impairment in individuals with DMD is thought to be due to an abnor...

Duchenne muscular dystrophy (DMD), the most common form of muscular dystrophy, is characterized by muscular wasting caused by dystrophin deficiency that ultimately ends in force reduction and premature death. In addition to primary genetic defect, several mechanisms contribute to DMD pathogenesis. Recently, antioxidant supplementation was shown to be effective in the treatment of multiple disea...

In 1971 a patient with suxamethonium-induced cardiac arrest in an unsuspected case of pseudohypertrophic muscular dystrophy was described (Genever, 1971). Suxamethonium has been implicated in several cases of muscular rigidity, hyperkalaemia and cardiac arrest and in malignant hyperpyrexia, and there is evidence that these reactions occur often when there are pre-existing muscular disorders inc...

Chronic spinal muscular atrophy of FSH type affecting a mother and her son and daughter is reported. The relevant literature is reviewed and the relation between this conditon and Kugelberg-Welander (K-W) disease is discussed. Chronic spinal muscular atrophy of FSH type is considered to be a different entity from the eponymous K-W disease. Each type of muscular dystrophy, e.g. limb-girdle, FSH,...

Since the identification of dystrophin as the causative factor in Duchenne muscular dystrophy, an increasing amount of information on the molecular basis of muscular dystrophies has facilitated the division of these heterogeneous disorders into distinct groups. As more light is being shed on the genes and proteins involved in muscular dystrophy, diagnosis of patients has improved enormously. In...

Single motor unit potentials recorded from surface electrodes over the extensor digitorum brevis muscle and evoked by stimulation of the anterior tibial nerve at the ankle were obtained by a computer subtraction method. Their latencies, durations, amplitudes, and areas were measured in control subjects and patients with Duchenne, limb-girdle, facioscapulohumeral, and myotonic muscular dystrophy...

MANY observers have reported pathologic changes in the myoeardium of patients with muscular dystrophy similar to those in the skeletal muscles.'-8 Clinical evidence of involvement of the heart has also been noted, consisting of persistent tachycardia,9 10 arrhythmias,10 congestive heart failure, chest pain, cardiac enlargement, changes in heart sounds, murmurs, electrocardiographic alterations ...

Abstract Muscular dystrophies are devastating and untreatable genetic diseases leading to progressive muscle degeneration weakness. The expanding landscape of CRISPR-Cas-based genome editing tools allows the in situ repair many disease-causing mutations patient cells an unprecedented manner. Here, I discuss recent advances challenges for using gene edited stem autologous cell replacement therap...

Emery-Dreifuss muscular dystrophy (EDMD) is an X-linked humeroperoneal dystrophy associated with cardiomyopathy that is distinct from the Duchenne and Becker forms of X-linked muscular dystrophy. Linkage analysis has assigned EDMD to the terminal region of the human X chromosome long arm. We report here further linkage analysis in two multigenerational EDMD families using seven Xq28 marker loci...

Myofibrillar protein catabolism has been calculated in a variety of neuromuscular diseases from the amount of 3-methylhistidine excreted in the urine. It was found to be significantly raised in Duchenne type muscular dystrophy, motor neurone disease, polymyositis, and thyrotoxic myopathy. In Becker type muscular dystrophy the level was slightly raised. It was normal in scapuloperoneal and limb...
