OBJECTIVES Alzheimer's disease assessment scale-cognitive subscale (ADAS-Cog) has become a standard clinical trials outcome for cognition, but has been recognized as deficient in areas including coverage of cognitive domains, sensitivity and standardization. Computerized test batteries may address some of these issues. The cognitive drug research(More)
Seventeen non-treatment seeking cocaine-dependent individuals participated in three-week longitudinal inpatient studies of cognitive changes during drug use and abstinence. Protocols included three days drug-free baseline, three days cocaine self-administration, and two weeks complete abstinence. A repeatable cognitive battery showed attention and delayed(More)
An international trial comparing remacemide hydrochloride with carbamazepine was undertaken in individuals with newly diagnosed epilepsy using a novel double-blind, parallel-group, double triangular sequential design. Patients with two or more partial or generalized tonic-clonic seizures in the previous year were randomized to remacemide or carbamazepine(More)
In a 24-week, randomized, double-blind, placebo-controlled, multicenter study of rivastigmine, 487 patients with dementia associated with Parkinson disease underwent assessment of attention on the Cognitive Drug Research computerized cognitive assessment system before dosing and 16 and 24 weeks later. Significant benefits of rivastigmine over placebo were(More)
Cognitive dysfunction characterizes all the various forms of dementia. Evidence is accumulating that all of the progressive neurodegenerative dementias, such as Alzheimer's disease (AD), are preceded by years, if not decades, of pathological cognitive decline. The limited effectiveness of the four current medications registered for AD together with the(More)
OBJECTIVE The purpose of this study was to explore the relationship between combat-related posttraumatic stress disorder (PTSD) and specific augmentation versus reduction patterns for the N100 and P200 components of auditory event-related potentials evoked by tones of increasing intensity. METHOD Event-related potentials of subjects with PTSD (N=36),(More)
Five cocaine-dependent individuals completed a 22-day inpatient study of sleep and cognition. Following 3 days of drug-free baseline, participants underwent 3 days of twice-daily smoked cocaine base self-administration (6 50-mg doses, 14 minutes apart), followed by 15 days of abstinence. Each morning and afternoon, the CDR repeatable, multiple-version,(More)
This was a double-blind, randomised, placebo-controlled, crossover study of the acute cognitive and subjective effects of nabilone 1-3 mg in healthy male volunteers. The Cognitive Drug Research computerised system (CDR system) was used to assess changes in attention, working and episodic memory. In addition, a number of self-ratings were conducted including(More)
BACKGROUND There is need for a cognitive test battery that can be easily used in clinical practice to detect or monitor cognitive performance in patients with multiple sclerosis (MS). In order to conduct, in this patient group, a preliminary investigation of the validity and utility of a brief computerized battery, the Cognitive Drug Research (CDR) battery,(More)
