Abstract

Objective: Clinicians monitor cognitive effects of drugs primarily by asking patients to describe their side effects. We examined the relationship of subjective perception of cognition to mood and objective cognitive performance in healthy volunteers and neurological patients. Methods: Three separate experiments used healthy adults treated with lamotrigine (LTG) and topiramate (TPM), adults with epilepsy on LTG or TPM, and patients with idiopathic Parkinson's disease. Correlations were calculated for change scores on and off drugs in the first two experiments and for the single assessment in Experiment 3. Results: Across all three experiments, significant correlations were more frequent (χ² = 259, P ≤ 0.000) for mood versus subjective cognitive perception (59%) compared with subjective versus objective cognition (2%) and mood versus objective cognitive performance (2%). Conclusions: Subjective perception of cognitive effects is related more to mood than objective performance. Clinicians should be aware of this relationship when assessing patients' cognitive complaints.

Funding Information:
The following people performed statistical analyses: Experiment 1 (healthy volunteers)—co-author V.J. Vahle while at Washington University, St. Louis; Experiment 2 (patients with epilepsy)—A.E. Hammer, Biomedical Data Sciences, GlaxoSmithKline; Experiment 3 (Parkinson’s disease)—co-author A. Roy while at the University of Florida. This work was also supported by the Center of Excellence grant from the National Parkinson Foundation and the UF INFORM-PD database. Though the actual research reported in this paper was not supported by NIH, I was being supported by an NIH grant (100% effort) via a Career Development Award (K01) during the time that I wrote the paper.
