Purpose:
The association of self-reported subclinical depressive symptoms and negative mood states with cognitive functioning was evaluated in 51 consecutive newly diagnosed adult persons with epilepsy.
Methods:
Emotional state was assessed with Profile of Mood States (POMS) and Brief Depression Scale (BDS) and was correlated with a battery of neuropsychological tests.
Results:
Patients with epilepsy reported more depressive symptoms in BDS than in controls. They also had more feeling of bewilderment and less vigor on POMS. Higher scores in BDS and in POMS inefficiency scale were associated with slower nondominant hand tapping, but emotional state did not correlate with cognitive measures within the epilepsy group.
Conclusions:
Self-reported symptoms of depression and negative mood states were not extensively or significantly associated with cognitive function, and they do not explain the cognitive impairments observed in cognition in newly diagnosed patients with epilepsy.
