Study Shows 'SuperAgers' Have Thicker Cortex, No Atrophy
MONDAY, Aug. 20 (HealthDay News) -- 'SuperAgers,' individuals over the age of 80 with episodic memory performance as good as normative values for 50- to 65-year-olds, do exist, and they have a thicker cerebral cortex, with no atrophy, according to a study published online Aug. 16 in the Journal of the International Neuropsychological Society.
Karate Black Belts Have Differences in Brain Structure
MONDAY, Aug. 20 (HealthDay News) -- Black belts in karate have differences in white matter brain structure that are associated with their voluntary control of movement, according to a study published online Aug. 14 in Cerebral Cortex.
Brain Measurements Predict Age With 92 Percent Accuracy
THURSDAY, Aug. 16 (HealthDay News) -- Using measurements of more than 200 structural features of the brain, a child's age can be predicted with over 92 percent accuracy, according to a study published online Aug. 16 in Current Biology.
Atypical Functional Brain Activation Seen in Leukoaraiosis
TUESDAY, Aug. 14 (HealthDay News) -- Leukoaraiosis correlates with atypical functional activation during semantic decision tasks, according to a study published online Aug. 13 in Radiology.
High-Field MRI Superior for Delineation of Alar Ligaments
FRIDAY, Aug. 10 (HealthDay News) -- High-field magnetic resonance imaging (MRI) (1.5 Tesla [T], 3 T) is superior to low-field MRI (1 T) for the delineation of alar ligaments (AL), but the field strength does not influence signal intensity in healthy volunteers, according to a study published in the Aug. 1 issue of Spine.
Global Brain Connectivity Linked to Intelligence
WEDNESDAY, Aug. 8 (HealthDay News) -- The activity of the lateral prefrontal cortex of the brain and its level of connectivity with other brain regions predicts intelligence, according to a study published in the June 27 issue of The Journal of Neuroscience.
Racial Disparity in CT Use for Children With Head Trauma
WEDNESDAY, Aug. 8 (HealthDay News) -- Minority children with minor blunt head trauma and low or intermediate risk for clinically important traumatic brain injury are significantly less likely to receive cranial computed tomography (CT) in the emergency department than their nonminority peers with the same risk, according to a study published in the August issue of the Archives of Pediatrics & Adolescent Medicine.
Limitations ID'd in Women's Breast Health in Pakistan
TUESDAY, Aug. 7 (HealthDay News) -- Women in Pakistan need more awareness about breast health and access to early detection, and there is marked inconsistency among general practitioners (GPs) with respect to screening practices, work-up, and management, according to a study published in the August issue of the Journal of the American College of Radiology.
Superficial X-Ray Viable for Basal, Squamous Cell Carcinoma
MONDAY, Aug. 6 (HealthDay News) -- Superficial X-ray therapy remains a viable treatment for primary basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in select patients, according to a study published online July 23 in the Journal of the American Academy of Dermatology.
Thigh Muscle Density Linked to Physical Functioning in RA
