Cognitive-Motor Dissociation in Patients Admitted to ICUs After Acute Brain Injuries
In a large, prospective, single-center study, more than one in six patients with acute brain injuries may have cognitive-motor dissociation (CMD) (e.g., they harbor capacity to modulate their brain activity in response to motor commands while remaining behaviorally unresponsive at the bedside). Some acute CMD patients were found to have a much higher chance for recovery of neurological functions and for reaching independent levels of activities of daily living by 12 months after brain injury.

Mind-Body Techniques May Enhance Cognitive Fitness in Older Adults
A meta-analysis regarding mind-body techniques and cognitive fitness in older adults points to enhanced cognitive performance associated with mind-body interventions in older persons — especially those without preexisting cognitive decline.

Eating Blue for Your Gray Matter: A Review of Blueberries and Cognitive Function
Healthy older adults, as well as those with subjective cognitive impairment or meeting criteria for mild cognitive impairment, could consider including blueberries as part of a Mediterranean-like diet to help reduce the risk of cognitive decline.

Making Sense of Delirium in the Emergency Department
Delirium is a complex disorder marked by the acute onset of mental status change with an associated fluctuating course. Despite the fact that delirium is a common clinical entity in elderly hospitalized patients, the condition may present in any patient regardless of medical comorbidities. Recognition within the emergency setting is becoming increasingly important, as the diagnosis frequently is missed.

Predicting the Risk of Mild Cognitive Impairment Using Imaging Biomarkers
In this population-based study, researchers used imaging biomarkers of amyloid and neuronal injury to estimate an absolute risk of mild cognitive impairment in the elderly.

The Mediterranean Diet and Cognitive Function: Keep the Mind Sharp
Italian seniors who ate a high-quality Mediterranean diet had better cognitive function than those who did not.

Effect of Diet on Hippocampal Volume in a Population at Risk for Alzheimer’s Disease
Magnetic resonance imaging of the brain in community-dwelling people (average age of 60 years) found that a long-term, high-quality diet was associated with larger hippocampal volumes after an average interval of 11 years.

Quality of Life After Focused Ultrasound Thalamotomy in Parkinson’s Disease
Mood, cognitive, and behavioral changes in tremor-predominant Parkinson’s disease patients, three and 12 months after receiving MRI-guided focused ultrasound thalamotomy, were correlated with quality of life more than the severity of tremor reduction.

Longitudinal tau PET as an Outcome Measure for Clinical Trials
tau PET imaging shows progression of brain Alzheimer’s pathology over time and correlates with cognitive impairment better than amyloid PET. In future clinical trials, tau PET can serve as a biomarker for Alzheimer’s disease progression.
