The Clock Drawing Test (CDT) is a common neuropsychological measure sensitive to cognitive changes and functional skills (e.g., driving test performance) among older adults. However, normative data have not been adequately developed. We report the distribution of CDT scores using three common scoring systems [Mendez, M. F., Ala, T., & Underwood, K. L.(More)
The authors conducted a study of clock drawing test scoring by dementia specialists to determine interrater reliability and diagnostic accuracy. The authors randomly assigned 25 clocks from each of six predetermined groups based on consensus diagnosis (cognitive comparison subjects, subjects with a memory complaint but with normal neuropsychological(More)
BACKGROUND A patient's response to treatment may be influenced by the expectations that the patient has before initiating treatment. In the context of clinical trials, the influence of participant expectancy may blur the distinction between real and sham treatments, reducing statistical power to detect specific treatment effects. There is therefore a need(More)
Dysfunction in circuits linking frontal cortex and basal ganglia (BG) is strongly implicated in obsessive-compulsive disorder (OCD). On MRI studies, neuropsychiatric disorders with known BG pathology have abnormally short T2 relaxation values (a putative biomarker of elevated iron) in this region. We asked if BG T2 values are abnormal in OCD. We measured(More)
The neurological deterioration in dementia is associated with disturbances in circadian rhythms and rest-activity patterns. These disruptions have been documented in Alzheimer's disease (AD) and dementia with Lewy bodies but little is known about rest-activity patterns in patients with frontotemporal dementia (FTD). We report longitudinal (2 year)(More)
Physical well-being has been designated a top priority for the children in the Clovis (California) Unified School District. In an effort to diminish coronary risk factors and encourage a healthy life style, a health assessment battery was developed for students in grades 1 through 6. The battery included measurements in height, weight, blood pressure, sit(More)
OBJECTIVE To examine the prevalence of antilipemic drug use, demographic characteristics of patients using these drugs, and the prevalence of hypercholesterolemia in the Nova Scotia population over 65 years of age. DESIGN Information was collected on the prescribing of antilipemic drugs using Nova Scotia Medical Services Insurance Pharmacare program data(More)
OBJECTIVES Older persons with schizophrenia develop problems associated with aging, such as poor mobility, at more rapid rates than people without serious mental illness. Decrements in mobility contribute to poor health outcomes. Impaired neurocognitive function and psychiatric symptoms are central aspects of schizophrenia. The purpose of this study was to(More)
Proportion congruency effects are the observation that the magnitude of the Stroop effect increases as the proportion of congruent trials in a block increases. Contemporary work shows that proportion effects can be specific to a particular context. For example, in a Simon task in which items appearing above fixation are mostly congruent and items appearing(More)
