[Congenital and endogenous endocrine myopathy]

Area of Science:

• Neurology
• Endocrinology
• Muscle Physiology

Context:

• Endocrinological pathway disorders rarely manifest as myopathy, necessitating interdisciplinary neurological and endocrinological evaluation.
• Asymptomatic or subtle (forme fruste) variants of endocrine myopathy are likely underdiagnosed.
• Hormonal metabolism's dependence on protein synthesis, electrolytes, and carbohydrates can precipitate rare myopathies.

Purpose:

• To highlight the essential interdisciplinary approach for diagnosing rare endocrine myopathies.
• To underscore the potential underdiagnosis of subtle endocrine myopathy presentations.
• To elucidate the mechanisms linking hormonal dysregulation to myopathy.

Summary:

• Endocrine myopathies typically present with proximal muscle weakness, myalgia, and atrophy, stemming from hormonal imbalances.
• These neuromuscular symptoms are usually reversible upon successful treatment of the primary endocrine disease.
• The severity of the underlying endocrinopathy directly correlates with the long-term clinical prognosis.

Impact:

• Enhances understanding of rare myopathy etiologies.
• Promotes earlier and more accurate diagnosis of endocrine-related muscle disorders.
• Guides clinical management strategies for improved patient outcomes in endocrine myopathies.
