We explored the nature of the visuospatial deficit in Parkinson's disease (PD) and its progression as a function of disease duration. We compared the performance of 183 patients with idiopathic PD and 90 control subjects matched for age and education on six visuospatial measures. We divided patients into three groups according to the disease duration: early (1 to 4 years), middle (5 to 10 years), and advanced (greater than 10 years). Performance deteriorated in five of the six visuospatial measures, as a function of disease duration. However, the pattern of visuospatial decline depended on whether dementia was present. The results were not influenced by age or anticholinergic medication. These findings support the presence of visuospatial deficits in PD patients, with a changing pattern of impairment related to dementia and progression of the disease.

For a 2-year period, all patients admitted to the inpatient adult EEG videotelemetry unit of the University of Miami School of Medicine underwent attempted event induction with intravenous normal saline placebo. Of 175 patients monitored during that period, 101 underwent attempted placebo saline induction, whereas 58 patients were either in the pediatric age group, were undergoing a repeat hospitalization (i.e., depth electrode monitoring), or refused induction. The final diagnosis in each patient was established after review of the history; physical, interictal, and ictal EEG findings; brain imaging studies; interictal and postictal brain single photon emission computed tomography (SPECT) and serum prolactin levels; psychiatric and psychological evaluations; and detailed neuropsychological testing. Final diagnoses were separated into epilepsy alone, pseudoseizures, epilepsy and pseudoseizures, and other (neither epilepsy nor pseudoseizures). No patient with an eventual diagnosis of epilepsy alone was inducible. Forty-one patients with a diagnosis of epilepsy were not inducible. Of 32 patients with an eventual diagnosis of pseudoseizures, 29 were inducible. One of these 29 was also diagnosed with epilepsy. Three patients with an eventual diagnosis of pseudoseizures were not inducible; 90.6% of patients with an eventual diagnosis of pseudoseizures were inducible, i.e., had events identical to those reported by history, after injection of saline placebo. Placebo saline injection is a safe and effective means of distinguishing epilepsy from pseudoseizures.
