Thirty patients were examined to test the hypothesis that a depletion of iron levels is associated with symptoms of akathisia. Fifteen akathisic patients were pair-matched with 15 non-akathisic patients.
Plasma ferritin levels were significantly decreased in the akathisic patients, and there was a significant inverse correlation between plasma iron levels and akathisia rating. In addition, akathisia ratings were found to be correlated with a scale measuring symptoms of tardive dyskinesia.
