Hippocampal volumes among older Indian adults: Comparison with Alzheimer's disease and mild cognitive impairment
Conclusion: The volume of the hippocampus in older Indian adults was 2.77 ± 0. 6 cm3 on the right side and 2.73 ± 0.52 cm3 on the left side. There was a significant hippocampal volume loss in MCI/AD compared to cognitively normal subjects.

Dementia risk after spontaneous intracerebral haemorrhage: a prospective cohort study
Publication date: July 2016 Source:The Lancet Neurology, Volume 15, Issue 8 Author(s): Solène Moulin, Julien Labreuche, Stéphanie Bombois, Costanza Rossi, Gregoire Boulouis, Hilde Hénon, Alain Duhamel, Didier Leys, Charlotte Cordonnier Background Dementia occurs in at least 10% of patients within 1 year after stroke. However, the risk of dementia after spontaneous intracerebral haemorrhage that accounts for about 15% of all strokes has not been investigated in prospective studies. We aimed to determine the incidence of dementia and risk factors after an intracerebral haemorrhage. Methods We did a prospective...

The use of a portable three-lead ECG monitor to detect atrial fibrillation in general practice.
CONCLUSIONS: The inexpensive portable PEM device recording diagnosed AF with a high sensitivity and specificity. KEY POINTS Simple ECG monitors could be useful to identify atrial fibrillation and thereby lead to a better prevention of stroke. The PEM device was easy to use and 95.7% of the recordings were technically acceptable for detecting atrial fibrillation. The PEM device has a high sensitivity and specificity in detecting atrial fibrillation compared to a standard 12-lead ECG. Further studies should evaluate the clinical usefulness of the PEM device, e.g. to detect intermittent atrial fibrillation.

MRI scan may help diagnose chronic traumatic encephalopathy, UCLA researchers report
UCLA doctors have found what may be an earlier and easier way to diagnose chronic traumatic encephalopathy, or CTE, a disorder that is thought to affect some former football players and others with a history of repetitive brain trauma.
Using a new software tool for analyzing MRI scans, the researchers detected the shrinkage of several key brain regions in a former football player with cognitive problems. The same pattern of brain changes is commonly seen in CTE cases that have been confirmed by autopsies after a person’s death.
While the findings from this single case report are preliminary, they raise the possibility th...

Philips launches Intellispace Portal 9.0 radiological visual analysis & quantification platform
Royal Philips (NYSE:PHG) said today it launched its IntelliSpace Portal 9.0, the most recent iteration of its radiological visual analysis and quantification platform.
The new version of the platform utilizes machine learning to aid operating radiologists in detecting, diagnosing and following-up on treatment for diseases and traumas, such as brain juries and neurological disorders including dementia, stroke, amyotrophic lateral sclerosis and multiple sclerosis.
“As the rates of dementia and neurodegeneration rise, neuroradiologists need advanced tools to help referring physicians treat these challenging cases. Inte...

Analyzing brain patterns may help neuroscientists increase people ’s confidence, reduce fear
A new technique of analyzing brain patterns appears to help people overcome fear and build self-confidence.The approach, developed by a UCLA-led team of neuroscientists, is described in two new papers, published in the journals Nature Communications and Nature Human Behaviour.Their method could have implications for treating people with depression, dementia and anxiety disorders, including post-traumatic stress disorder, said Hakwan Lau, a UCLA associate professor of psychology and the senior author of both studies. It could also play a role in improving leadership training for executives and managers.In theNature Human Be...

Cerebral glucose metabolism and cognition in newly diagnosed Parkinson's disease: ICICLE-PD study
Conclusions
Reductions in cortical FDG metabolism were present in newly diagnosed PD, and correlated with performance on neuropsychological tests. A reduced baseline parietal metabolism is associated with risk of cognitive decline and may represent a potential biomarker for this state and the development of PD dementia.

Differential Associations of Socioeconomic Status With Global Brain Volumes and White Matter Lesions in African American and White Adults: the HANDLS SCAN Study
Objective: The aim of the study was to examine interactive relations of race and socioeconomic status (SES) to magnetic resonance imaging (MRI)–assessed global brain outcomes with previously demonstrated prognostic significance for stroke, dementia, and mortality.
Methods: Participants were 147 African Americans (AAs) and whites (ages 33–71 years; 43% AA; 56% female; 26% below poverty) in the Healthy Aging in Neighborhoods of Diversity across the Life Span SCAN substudy. Cranial MRI was conducted using a 3.0 T unit. White matter (WM) lesion volumes and total brain, gray matter, and WM volumes were computed. An SES com...

Incidence and risk factors of leukoaraiosis from 4683 hospitalized patients: A cross-sectional study
This study revealed that the incidence of LA is high in hospitalized patients in China; moreover, age, sex, hypertension, diabetes mellitus, smoking, drinking, and abnormal HCY and LDL-C levels were found to be associated with overall LA risk, LA onset, or LA progression. These results provide insight into strategies for the prevention and treatment of LA.

Anosognosia Is an Independent Predictor of Conversion From Mild Cognitive Impairment to Alzheimer's Disease and Is Associated With Reduced Brain Metabolism.
CONCLUSIONS: Anosognosia in AD is related to brain glucose hypometabolism. Further, anosognosia independently predicts conversion from MCI to AD. The absence of anosognosia may be clinically useful to identify those patients that are unlikely to convert from MCI to AD.
