Definition
A disease or disorder affecting muscle tissue
Clinical context
A 65-year-old man presents with progressive weakness in his proximal muscles, making it difficult to climb stairs and rise from seated positions. He reports muscle aches but no sensory deficits. Physical examination reveals symmetric muscle weakness without reflex abnormalities. A muscle biopsy shows degeneration of muscle fibers with minimal inflammatory infiltrate.
Mnemonic
MYOpathy = MUSCLE weakness, MYO = muscle, pathy = disease
