Psychomotor Slowing

Researchers in the Netherlands and Belgium studied 35 women with CFS with no history of depression and 25 healthy female control subjects. They tested cognitive and fine motor processing of visual-spatial information, measured by recording reaction time (RT) and movement time (MT), respectively. CFS was significantly associated with longer RT and MT in the pooled and in the task-specific analyses. These performance data on the figure-copying tasks provide confirmatory evidence for psychomotor slowing in CFS, but not for a disturbed inhibition of automatic responses. The authors conclude that computerised figure-copying tasks may be promising tools for use in neurobiological research and clinical trials in CFS. (Journal of Psychiatry Research, Apr. 30, 2011)
