AI-based neuroimaging approach helps predict Alzheimer's disease

2017 22 Dec

Machine learning techniques such as support vector machine (SVM) have been applied recently in order to accurately classify individuals with neuropsychiatric disorders such as Alzheimer's disease (AD) based on neuroimaging data. However, the multivariate nature of the SVM approach often precludes the identification of the brain regions that contribute... Read more

Current Screening Misses Early Dementia Diagnosis

2016 24 May

While changes in cognitive abilities may not be severe enough to disrupt daily life, a clinical diagnosis of mild cognitive impairment (MCI) indicates an increased risk of eventually developing Alzheimer’s disease or another type of dementia. In a paper published in the Journal of Alzheimer’s Disease , researchers at University of California... Read more

Happiness in an MRI

2015 26 Nov

Happiness is a subjective experience; for instance, some people feel happiness more intensely than others when they receive compliments. To better understand the neural mechanism behind how happiness emerges, researchers in Japan conducted a study using MRI brain scans. Overall happiness, according to the study, is a combination of happy emotions and... Read more

Brain Imaging Boosts Efforts to Lower Alzheimer's Risk

2015 08 Jun

A report published in American Journal of Neuroradiology (AJNR) discusses how cognitive decline can be identified early and prevented by applying quantitative brain imaging techniques. Amidst growing evidence that neurodegenerative diseases alter brain structures, use of quantitative brain imaging is gaining popularity among clinicians as this helps... Read more

Neuroimaging Not Helpful in Sports Concussion Diagnosis

2015 07 Jun

Results of a new study tend to support the prevalent opinion among physicians specialising in sports-related concussion (SRC) that neuroimaging is not that useful in diagnosing SRCs. Researchers from the Canada North Concussion Network in Manitoba examined neuroimaging studies in children and adolescents with SRCs and found that the images appeared... Read more

Managing Incidental Findings Found During Neuroimaging

2015 31 Mar

Neuroimaging is an important diagnostic tool in the assessment of neurological disease, but often unmasks incidental findings (IFs). The negative impacts of IFs, such as patient anxiety, present neurologists with management dilemmas, largely due to the limited knowledge base surrounding the medical significance of these IFs. Specifically, the lack of... Read more

Reducing Imaging Scans For Headaches May Delay Diagnosis

2014 30 Dec

According to an article published in the January issue of Neurosurgery , recent guidelines that seek to reduce the use of neuroimaging tests for patients with headaches run the risk of either missing or delaying the diagnosis of brain tumours. The article was written by Neurosurgeon Dr. Ammar H. Hawasli and colleagues of Washington University School... Read more

Neuroimaging For Personalised Pain Therapy

2014 20 Sep

New research indicates that changes in functional connectivity between brain regions, as can be measured by magnetic resonance imaging (MRI) of the resting state, may underlie the pathogenesis of fibromyalgia and other chronic pain states. As such, this parameter maybe used to monitor changes in brain function associated with pharmacological treatment,... Read more
