Amyotrophy: A Comprehensive Guide to Its Symptoms and Prognosis

6. Neuralgic Amyotrophy

Neuralgic amyotrophy affects the peripheral nerves in upper limbs, most often in men in their early twenties. While not a permanent or continuous disorder, the condition can be recurrent in a minority of cases. There is usually no known cause or trigger, though some cases occur within hours or weeks of upper respiratory tract infections, vaccinations, childbirth, and invasive medical procedures.
