Su et al. (2014) also found that elevated baseline CRP levels were associated with an upregulated risk of persistent PCS (2.72; 95% CI: 1.61–4.59), persistent psychological issues (1.54; 95% CI: 1.06–2.22), and persistent cognitive impairments (1.69; 95% CI: 1.14–2.51) within the mTBI population. The gene discussed is CRP; the disease is concussion.
