PURPOSE: The case of a patient with Parkinson's disease (PD) who experienced profound encephalopathy after short-term exposure to metoclopramide is described. SUMMARY: A 79-year-old man with PD received metoclopramide (10 mg i.v. every six hours) for stimulation of gastric motility after a colon resection; the first of three doses of the drug was administered about 30 minutes after completion of the afternoon procedure. The evening after surgery, the patient appeared to be resting comfortably without pain, although he was somewhat agitated; two more metoclopramide doses were administered during the night. Over the next several hours his mental status deteriorated, and the next morning he was found to be unresponsive and could not be aroused. Although the patient had received minimal narcotics, naloxone was administered but failed to produce an improvement in the patient's mental status. The results of laboratory tests, computer tomography scanning, and other diagnostic studies ruled out cardiac ischemia, infectious disease, and other potential causes of the abrupt change in mental status. Within eight days of the discontinuation of metoclopramide use, the patient gradually returned to his baseline mental status. The application of the algorithm of Naranjo et al. in this case indicated a possible adverse reaction to metoclopramide as the cause of acute metabolic encephalopathy, with the patient's underlying PD and PD-related dementia suspected to have been contributing factors. CONCLUSION: A 79-year-old man with long-term PD developed acute encephalopathy after the administration of i.v. metoclopramide.

Infantile nephropathic cystinosis is a genetic metabolic disorder in which the amino acid cystine accumulates in various organs, including the kidney, cornea, thyroid, and brain. Despite normal intellect, individuals with cystinosis may have specific impairments in the processing of visual information. To examine further the specific types of deficits in visual processing found in individuals with cystinosis, we administered the Development Test of Visual-motor Integration to 26 children with cystinosis (4 to 16 yr. old) and 26 matched controls. The cystinosis group achieved a significantly lower standard score, raw score, and mean ceiling than did the control group. Qualitative analyses showed that in the cystinosis group, size within errors and rotation errors were more prevalent than in the control group. Correlational analyses showed that with advancing age, the cystinosis subjects tended to fall further behind their chronological age. Our data, together with the findings of previous studies, suggest that the visuospatial difficulties in children with cystinosis may be due to inadequate perception or processing of visually presented information. Furthermore, the increasing discrepancy with age may reflect a progressive cognitive impairment, possibly as a result of cystine accumulation in the brain over time.
