Regionally specific atrophy of the corpus callosum in AD, MCI and cognitive complaints.

The goal of the present study was to determine if there are global or regionally specific decreases in callosal area in early Alzheimer's disease (AD) and mild cognitive impairment (MCI). In addition, this study examined the corpus callosum of healthy older adults who have subjective cognitive complaints (CC) but perform within normal limits on neuropsychological tests. We used a semi-automated procedure to examine the total and regional areas of the corpus callosum in 22 patients with early AD, 28 patients with amnestic MCI, 28 healthy older adults with cognitive complaints, and 50 demographically matched healthy controls (HC).

FLAIR lesion volume in multiple sclerosis: relation to processing speed and verbal memory.

Information processing speed and episodic memory are two commonly affected cognitive abilities in MS. Insights into the mechanisms of and relationships between these abilities have recently come from structural neuroimaging techniques, but few studies have used fluid-attenuated inversion recovery (FLAIR), a neuroimaging sequence known to be sensitive to cortical and juxtacortical lesions in MS. We hypothesized that a volumetric index of FLAIR total lesion volume (TLV) would be associated with slowed processing speed and verbal memory dysfunction in MS.

Injuries to Scottish farmers while tagging and clipping cattle: a cross-sectional survey.

Background: Anecdotal reports suggested that farmers were sustaining significant injuries while ear tagging newborn calves or clipping cattle prior to slaughter.

Aims: This national survey was designed for determining the incidence and nature of self-reported injuries to farmers that were sustained while tagging calves and clipping cattle.

Methods: A cross-sectional, anonymous, postal questionnaire survey was sent to all members of the National Farmers Union of Scotland with beef or dairy cattle (n = 4495).
