Long-term post-concussion symptoms.

Concussion is common and usually resolves without complications. However, persistent symptoms occur in 10-15 % of patients. These post-concussion symptoms are predominantly somatic, cognitive and emotional. The condition is most common in those with previous somatic and mental health issues. The causes underlying long-term post-concussion symptoms are unclear, but a biopsychosocial explanatory model is currently regarded as the most appropriate basis for diagnosis and treatment. This clinical review article is based on key literature and our own clinical experiences with patients who have these long-term post-concussion symptoms.
