Some myopathies are more common in the elderly, such as inclusion body myositis and myopathy secondary to cholesterol lowering medication (statin myopathy).
Patients with myopathies survive longer with better care and the increasingly recognized negative impact of aging on physical function and quality of life. In addition to age associated loss of muscle mass and strength (sarcopenia), muscle weakness and fatigue from myopathy can limit independence due to mobility and ADL issues.1
