Cannabis use history as predictor of neurocognitive response to cannabis intoxication remains subject to scientific and policy debates. The present study assessed the influence of cannabis on neurocognition in cannabis users whose cannabis use history ranged from infrequent to daily use. Drug users (N = 122) received acute doses of cannabis (300 μg/kg THC), cocaine HCl (300 mg) and placebo. Coc...

AIMS To establish the norms for the letter-cancellation task-a psychomotor performance task. MATERIALS AND METHODS Eight hundred nineteen school students were selected in the present study in an age range between nine and 16 years (M = 12.14; SD = 1.78 years). Subjects were assessed once for the cancellation task. RESULTS Both age and sex influenced performance on the SLCT; therefore, corre...

1. After a fixed weight-related dose given intravenously, plasma diazepam concentrations were significantly lower in 11 cirrhotic patients than in controls matched for age and sex, in the 4 h after diazepam administration but not thereafter. 2. When measured at a single fixed time point, a greater proportion of the drug was in the unbound from in the plasma of cirrhotic patients, but non-bound ...

BACKGROUND Chronic hypoxemia has deleterious effects on psychomotor function that can affect daily life. There are no clear results regarding short term therapy with low concentrations of O2 in hypoxemic patients. We seek to demonstrate, by measuring the characteristics of drawing, these effects on psychomotor function of hypoxemic patients treated with O2. METHODS Eight patients (7/1) M/F, a...

We investigated mental health and cognitive function in 195 community-dwelling adults aged 18 to 92 years (M = 46.64). We assessed several cognitive domains, including psychomotor, executive function, and episodic memory. We found a significant Age x Mental Health interaction in relation to within-person (WP) variability (trial-to-trial variability in reaction time performance) in a four-choice...

The effects of four doses of alcohol (0.25 g/kg-1 g/kg) and placebo on a standard test battery of cognitive and psychomotor performance are described. The tests included critical flicker fusion threshold, choice reaction time, tracking and memory scanning. The results of this experiment are compared with those of a number of similar studies which examined the effects of other psychoactive subst...

Elderly patients with major depression and normal controls completed the Sternberg short-term memory scanning procedure and WAIS Digit Symbol. Depressed patients demonstrated psychomotor slowing on both tasks, but normal response latency as a function of memory set size on the Sternberg procedure. While cognitive-behavioural slowing may be observed in both depressive illness and subcortical neu...

This study, a cross-sectional study of adults who were administered the CNS Vital Signs test battery when it was being standardized, investigated whether there are gender differences in the rate of neurocognitive decline with age. As a group, men scored better on tests of visual memory, executive function and psychomotor speed. Women scored better in tests of verbal memory, processing speed, an...
