In general, outcomes in adults are tenuous. PNES severely affects the quality of life of affected patients. After having symptoms for ten years, more than half of all patients continue to have seizures and remain dependent on social security benefits.

Outcomes are improved with education, with an onset and diagnosis at a young age, with episodes characterized by nondramatic features, with few additional somatoform complaints, with low dissociation scores, and with low scores on the high-order personality dimensions (i.e., inhibition, emotional dysregulation, compulsivity).

Patients with the limp or catatonic type may have a better prognosis than those with the convulsive or thrashing type.
