Cognitive Impairment, Brain Insult After Mechanical Ventilation
2021 16 Mar
Mechanical ventilation is an essential treatment strategy in the ICU. It is a life-support tool that is often needed in critically ill patients. However, mechanical ventilation is known to cause injury to distal organs such as the lungs, diaphragm and brain. A systematic review was conducted to identify publications that assessed the link between... Read more
Cognitive Impairment After ARDS
2019 22 Nov
Acute respiratory distress syndrome (ARDS) is a serious disorder that causes severe hypoxia requiring mechanical ventilation. It affects approximately 200,000 patients in the US each year, accounting for 10% of ICU admissions and a mortality risk of 25-40%. In many cases, patients also develop dysfunction of other organs that leads to high morbidity... Read more
Amyloid PET improves evaluation of patients with cognitive impairment
2018 20 Jun
A prospective diagnostic study provides a bridge between validating amyloid positron emission tomography (PET) in a research setting and implementing this diagnostic tool in daily clinical practice. Both amyloid-positive and amyloid-negative results had substantial associations with changes in diagnosis and treatment, both in patients with and... Read more
ICU Delirium and Long-term Cognitive Impairment
2017 01 Aug
A prospective cohort study conducted in a tertiary level intensive care unit (ICU) in Queensland, Australia aims to investigate the relationship between patient delirium and long-term cognitive impairment. The findings, published in the journal Australian Critical Care, show that ICU delirium was positively associated with impaired information processing... Read more
MRI Predicts Cognitive Outcome in Preterm Children
2015 07 Sep
A study published in the neurology journal Brain suggests that children born prematurely are more likely to have low mathematical achievement at school age, which may be caused by reduced working memory and number skills. The study aimed to examine the use of magnetic resonance imaging (MRI) after birth to identify infants at risk of later academic... Read more
Cell Density Unchanged as Brain Shrinks With Age
2015 16 Jun
Using a powerful 9.4-Tesla MRI — the first of its kind for human imaging — researchers at the University of Illinois at Chicago have obtained the most detailed MRI images of the brain so far to show that while the brain shrinks with age, brain cell density remains constant. The findings are reported in the journal NMR in Biomedicine . The 9.4-Tesla... Read more
New MRI Diagnostic Test for Autism Spectrum Disorder
2015 17 Jan
A new brain imaging technique developed by scientists at Virginia Tech Carilion Research Institute may be able to identify children with autism spectrum disorder in just two minutes. This technique offers promising diagnostic potential once it undergoes more research and evaluation. Usually, diagnosis — an unquantifiable process based on clinical judgment... Read more
Virtual Reality Game Detects Condition Which Precedes Alzheimer’s Disease
2015 14 Jan
A new study by Greek researchers has demonstrated that a virtual reality game frequently used for cognitive training is effective as a screening tool for adults with mild cognitive impairment (MCI). The virtual supermarket (VSM) application was developed as part of a project which uses new technologies to screen, diagnose, treat and support patients... Read more
RSNA 2014: Study Links Asymptomatic Atherosclerosis to Cognitive Impairment
2014 25 Nov
A recent study of 2,000 adults reveals that a build-up of plaque in the body’s major arteries is associated with mild cognitive impairment. The study was conducted at the University of Texas (UT) Southwestern Medical Center and will be presented next week at the annual meeting of the Radiological Society of North America (RSNA). "It is well established... Read more
Shift Work Impairs Cognition Over Time
2014 13 Nov
An irregular work schedule can negatively influence health and socialisation due to a disruption of normal circadian rhythms. New research explored the impact of long-term shift work on cognition, and found that workers who were exposed to frequently changing schedules or odd work hours for more than ten years showed signs of cognitive impairment equal...
