Postconcussional Syndrome: Clinical Diagnosis and Treatment.

Diagnosis and treatment of postconcussional syndrome (PCS) is challenging because symptoms are vague, difficult to confirm, and attributable to other conditions. There are no uniformly accepted diagnostic PCS criteria. Clinical care largely focuses on symptom reduction and management. Moreover, the coronavirus disease 2019 (COVID-19) pandemic has increased the challenge because post-acute COVID-19 syndrome symptoms overlap with PCS. Future research should center on base rates of PCS-type symptoms in nonneurological samples and the identification and improved understanding of moderating variables contributing to the frequency, intensity, and duration of PCS symptoms.
