Cerebrospinal fluid levels of free fatty acid associated with ischemic stroke recurrence and functional outcome

The aim of this study was to evaluate the association between cerebrospinal fluid (CSF) levels of free fatty acid (FFA) and functional outcome and stroke recurrence in patients with ischemic stroke. In a prospective study, CSF levels of FFA were measured using an enzyme cycling method on admission in 217 consecutive patients with first-ever ischemic stroke. Clinical information was collected. Functional outcome and stroke recurrence were evaluated at 1-year follow-up. Multivariate analyses were performed using logistic regression models. The CSF FFA level was obtained in all patients with a median value of 0.22 (IQR 0.12–0.33) mmol/l. At admission, 89 patients (41.0 %) had a minor stroke (NIHSS
