Answer

Eighty percent of patients with brachial neuritis recover functionally within 2 years; 90% recover functionally within 3 years. [10]  A study by Feinberg et al found that at a mean period of 1 year, 31% of affected nerves in the study (or 52.9% of those in patients followed up for a full year) with Parsonage-Turner syndrome (acute brachial neuritis) had achieved complete electrodiagnostic recovery. [44]

Bilateral disease has a less favorable outcome than does unilateral disease, while lower trunk lesions have a less favorable prognosis than do upper trunk lesions.

The rate of recurrence in the inherited form is approximately 75%. The recurrence in the idiopathic form is thought to be between 5% and 26%. [45]
