Prognosis
Prognosis Prognosis is also very dependent of aetiology. E.g. congenital myopathies are chronic and progress over years, whereas other myopathies are more acute and can quickly lead to respiratory failure and other complications. [teesneuro.org]

Prognosis This depends on the specific diagnosis. The primary disorders are incurable conditions with varied prognosis. Secondary myopathy may be corrected by treating the underlying cause. [patient.info]
Prognosis Prognosis is quite good. In two to four months after euthryoid state is achieved, muscle weakness improves. But it may take up to a year for muscle bulk to return. Respiratory failure is very rare. [encyclopedia.com]
Etiology
Myopathy is a common term for a muscle disease that is unrelated to any disorder of innervation or neuromuscular junction, with a wide range of possible etiologies. [news-medical.net]
Physicians must be alert to the possibility of an endocrine etiology in cases of new-onset psychosis or behavior disturbance. Physicians must be alert to the possibility of malignancy as the underlying etiology for any endocrinopathy. [emedicine.medscape.com]
