Despite its wasting and at times long-lasting effects, most cases are resolved by the body's healing system, and recovery is usually good in 18–24 months, depending on how old the person in question is. For instance, a six-year-old could have brachial neuritis for only around 6 months, but a person in their early fifties could have it for over 3 years. It was traditionally thought that most people would regain around 70-90% of their original strength and function levels, however most recent studies suggest that long-term complications are more common than previously thought.
