Symptoms and Signs – Differential Diagnosis of Muscle Weakness
• Alcoholic myopathy
• Drug induced (e.g., statin myopathy)
• Electrolyte abnormalities (hypokalemia, hyperkalemia, hypophosphatemia, hypercalcemia, hypoglycemia)
• Endocrinopathies (e.g., adrenal insufficiency, hypothyroidism), diabetic neuropathy
• Impaired cardiac output (e.g., mitral stenosis, mitral regurgitation)
• Infections (polio, botulism, HIV, hepatitis, diphtheria, tick paralysis, neurosyphilis, brucellosis, TB, trichinosis)
• Inflammatory myopathies (e.g., collagen-vascular disease, rheumatoid arthritis [RA], sarcoidosis)
• Muscular dystrophies
• Myasthenia gravis, Lambert-Eaton syndrome
• Organophosphate or arsenic poisoning
• Other: motor neuron disease, mitochondrial myopathy, Ltryptophan (eosinophilia-myalgia), rhabdomyolysis, glycogen storage disease, lipid storage disease
• Pernicious anemia, other anemias, beriberi
• Physical deconditioning
• Psychiatric illness (depression, somatization syndrome)
• Steroid myopathy
• Uremia, liver failure
