Symptoms of mild traumatic brain injury typically resolve within days or weeks. However, a significant group of patients may report symptoms of Post-concussional Syndrome (PCS) weeks, months and years postinjury. This review presents an overview of the pathogenesis, diagnosis and treatment options for PCS. The authors review the evidence for factors that may predict such symptoms. At early phases, there are associations between neurological signs and symptoms, neurocognitive functions and self reports. Over time, such associations become less coherent, and psychological issues become particularly relevant. An accurate understanding of neurological and psychosocial factors at play in PCS is crucial for appropriate management of symptoms at various points postinjury.
