Methodological Factors in Determining Risk of Dementia After Transient Ischemic Attack and Stroke: (II) Effect of Attrition on Follow-Up.

Background And Purpose: Cognitive outcomes in cohorts and trials are often based only on face-to-face clinic assessment. However, cognitive impairment is strongly associated with increased morbidity and mortality, leading to substantial loss to clinic follow-up. In the absence of previous population-based data, we determined the effect of such attrition on measured risk of dementia after transient ischemic attack and stroke.

Impact of cataract surgery on sleep in patients receiving either ultraviolet-blocking or blue-filtering intraocular lens implants.

Purpose: Although visual impairment is a well-recognized consequence of cataract development, little is known about the ability of the melanopsin-based photosensitive retinal ganglion cells (pRGCs) to regulate sleep-wake timing in the presence of cataract. In this study, we replaced a cataractous natural crystalline lens with two different types of artificial intraocular lenses, a UV-blocking lens or a blue-filtering lens. We investigated the level of sleep disturbance before cataract surgery and any change in sleep due to improved light transmission following surgery and compared this in both types of intraocular lens.

Quality of life after TIA and stroke: ten-year results of the Oxford Vascular Study.

Objective: To evaluate the 5-year impact of stroke and TIA on utility and quality-adjusted survival.

Methods: TIA and stroke patients from a UK population-based study (Oxford Vascular Study) were recruited from 2002 to 2007, and followed up until 2012. Quality of life was assessed over 5 years using the EQ-5D (EuroQol-5 Dimensions), with responses converted into utilities ranging from -0.

Population-based study of disability and institutionalization after transient ischemic attack and stroke: 10-year results of the Oxford Vascular Study.

Background And Purpose: Long-term outcome information after transient ischemic attack (TIA) and stroke is required to help plan and allocate care services. We evaluated the impact of TIA and stroke on disability and institutionalization over 5 years using data from a population-based study.

Methods: Patients from a UK population-based cohort study (Oxford Vascular Study) were recruited from 2002 to 2007 and followed up to 2012.

Telephone assessment of cognition after transient ischemic attack and stroke: modified telephone interview of cognitive status and telephone Montreal Cognitive Assessment versus face-to-face Montreal Cognitive Assessment and neuropsychological battery.

Background And Purpose: Face-to-face cognitive testing is not always possible in large studies. Therefore, we assessed the telephone Montreal Cognitive Assessment (T-MoCA: MoCA items not requiring pencil and paper or visual stimulus) and the modified Telephone Interview of Cognitive Status (TICSm) against face-to-face cognitive tests in patients with transient ischemic attack (TIA) or stroke.

Methods: In a population-based study, consecutive community-dwelling patients underwent the MoCA and neuropsychological battery >1 year after TIA or stroke, followed by T-MoCA (22 points) and TICSm (39 points) at least 1 month later.
