Pseudoakathisia, akathisia and gender
Gervin & Barnes (2000) presented an overview of drug-related movement disorders and a brief standardised examination for their assessment. We were interested to be reminded of the presentation of pseudoakathisia and the suggestion that the condition seems to be more common in males. Halstead et al (1994) reported this association, although the difference was not statistically significant. In a study of the prevalence of akathisia in 64 patients with mental disorder at St Andrew's Hospital, we found that all four patients with pseudoakathisia were male, but of the 14 patients with akathisia, nine were female (Reference Stubbs and HalsteadStubbs et al, 2000). However, most epidemiological studies have not revealed any gender differences in vulnerability to akathisia itself.
A difference in susceptibility of the genders to developing akathisia and pseudoakathisia raises intriguing questions on the interrelationship between the two akathisia subgroups (Reference Halstead, Barnes and SpellerStubbs & Halstead, 2000).
