Effects of citicholine in subcortical dementia associated with Parkinson's disease assessed by quantified electroencephalography.
Two groups of patients with idiopathic Parkinson's disease underwent quantified electroencephalography (EEGq) using fast Fourier transfer to assess the effects of treatment with citicholine. Evidence of cortical cognitive impairment was seen in one group but not in the other. Certain parameters were established which enabled the two groups to be distinguished by examining specific EEGq indices. Specifically, differences were found in the overall potentials of the delta and alpha bands, in the alpha/theta index, in posterior activity, in the anteriorization index of the delta and alpha rhythms, and in the spatialization index of the alpha rhythm. The implications of these differences in the potential involvement of the frontal lobes in subcortical dementia in Parkinson's disease are discussed.
