Background: Low arachidonic acid (AA) levels are reportedly associated with unfavorable outcomes in intracerebral hemorrhage (ICH).
Objective: We aimed to clarify whether serum AA levels might be associated with a good recovery from severe motor paralysis in the early stage of hospitalization.
Methods: From among consecutive ICH patients between October 2012 and December 2021, patients with a sum of upper and lower extremity National Institutes of Health stroke scale (NIHSS) scores of 4-8 at admission (severe motor paralysis) were included. We defined good early recovery from severe motor paralysis as a sum of upper and lower extremity NIHSS scores of 0-3 on day 7 after admission, and that of individual upper and lower extremities as NIHSS scores of 0-1 on day 7 after admission. We aimed to assess whether serum AA levels might be associated with good early recovery from severe motor paralysis.
Results: We screened 377 consecutive ICH patients, including 140 with severe motor paralysis (88 (63%) males, median age 64 years). Recovery from severe motor paralysis was seen in 48 (34%). Higher AA levels (PR 1.243, 95% CI 1.042 to 1.483, p = 0.016) were independently associated with good overall recovery, and good recovery of upper and lower extremities separately (upper extremity: PR 1.319, 95% CI 1.101 to 1.580, p = 0.003; lower extremity: PR 1.293, 95% CI 1.115 to 1.499, p = 0.001).
Conclusions: Higher AA levels may contribute to a good early motor recovery in patients with severe motor paralysis due to ICH.
