Maladies musculaires de l’adulte : quand évoquer le diagnostic ?

Le résumé fourni par la source

Muscle diseases or myopathies have heterogeneous clinical presentations and etiologies. The principal sign is muscular weakness, whose distribution can help diagnostic orientation. Exercise intolerance, even without weakness at rest, can indicate an underlying myopathy. An isolated CK elevation can have multiple causes, but its persistence after a period of rest can point towards a subclinical myopathy. Isolated myalgia, especially at rest, are usually not associated with muscle disease. If the suspicion of myopathy is high, the patient will be assessed by a neurologist trained in muscle disorders, with correlation of clinical and neurophysiological findings, muscle imaging and, if indicated, muscle biopsy and genetic analysis. Cardiac and respiratory assessments are mandatory if a myopathy is suspected.
