Low serum iron status and akathisia.

26 patients were studied to assess the association between iron deficiency and akathisia. 13 akathisic patients were matched with 13 non-akathisic controls. Serum iron and percentage saturation were significantly decreased in the akathisic group, whereas total iron-binding capacity was significantly increased. A negative correlation between serum iron and akathisia rating (rs = -0.42) was also found.
