This project has employed a computerized pursuit meter which has a high correlation with operational performance (2) to test the principal antimotion sickness drugs. Proficiency scores on the pursuit meter task were improved over placebo scores in subjects with d-amphetamine 10 mg and 5 mg, the combination of promethazine 25 mg plus scopolamine 0.4 mg with(More)
The vestibular, cerebellar, and reticular systems are central in importance, in motion sickness and habituation, to the effects of motion. Nuclear medicine single photon emission computed tomography (SPECT) studies of cerebral blood flow and power spectral electroencephalographic recordings during motion sickness were used to determine alterations in the(More)
Twenty-nine elderly patients who failed treatment with clozapine, risperidone, or olanzapine entered this 24-week, single-center, open-label trial to assess the efficacy of quetiapine (12.5-400 mg/day) for psychosis in patients with Parkinson's disease (PD). Psychiatric, motor, and cognitive assessments were administered at baseline and at periodic(More)
The effect of antimotion sickness drugs on habituation was studied. Subjects were rotated once a day for 5 d to the malaise III end-point after receiving placebo, 1 mg scopolamine, 10 mg d-amphetamine, or the combination of 0.6 mg scopolamine with 5 mg of d-amphetamine. The placebo scores had a Spearman coefficient of correlation of 0.88 with the initial(More)
Scopolamine (1.0 mg) and d-amphetamine (10 mg) were administered alone and in combination to 16 subjects (medical students), randomly assigned to testing sessions in a fully crossed-over (Latin square) within-subjects design. After being practiced to stability, 9 performance tests from a menu of portable microcomputer-based tests were administered(More)
The present study was undertaken to improve previous testing procedures, involving the use of a slow rotation room, for assessing the efficacy of antimotion sickness drugs which had validity for groups of subjects but not for each individual in the group. Three major changes were introduced: first, the use of an incremental increase in the intensity of the(More)
UNLABELLED Eight subjects, male and female, were rotated using the step method to progressively increase the speed of rotation (+2 rpm) after every 40 head movements to a maximum of 35 rpm. The end-point for motion sickness was the Graybiel Malaise III total of symptoms short of frank nausea. The drug treatments were placebo, scopolamine 0.6 mg and 1 mg,(More)
In our view, the tearful feeling state is occasioned by the ego temporarily threatened with being inundated by complex memories and affects. For the moment, the ego cannot provide appropriate satisfying and integrated verbal expression. Words and verbal thinking are delayed. In this brief period, a controlled regression occurs during which the ego relates(More)
The authors consider the complex decisions involved in the initial consultation of a person looking for treatment when this person must be referred to a professional colleague. They explore the way decisions are made in the referral processes and the complex practical and transference-countertransference issues that arise at the outset and whenever second(More)
