Spending less time in REM (rapid eye movement) sleep and taking longer to enter REM sleep are separately associated with a higher risk of developing dementia.
People who get less rapid eye movement (REM) sleep may have a greater risk of developing dementia, according to a new study published in the Aug. 23, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology. REM sleep is the sleep stage when dreaming occurs.
Imagine if doctors could determine, many years in advance, who is likely to develop dementia. Such prognostic capabilities would give patients and their families time to plan and manage treatment and care. Thanks to artificial intelligence research conducted at McGill University, this kind of predictive power could soon be available to clinicians everywhere.
A study led by researchers at Cedars-Sinai and NeuroVision Imaging LLC provides the scientific basis for using noninvasive eye imaging to detect the pathological hallmarks of Alzheimer's. The experimental technology, developed by Cedars-Sinai and NeuroVision, scans the retina using techniques that can identify beta-amyloid protein deposits that mirror those in the brain.
In a recent paper, a team of McLean Hospital researchers reported that many health apps designed to assist dementia patients and their caregivers have inadequate security policies or lack security policies altogether.
A new paper published today in the journal Alzheimer's & Dementia: The Journal of the Alzheimer's Association found that accident and emergency (A&E) attendance among people with dementia in their last year of life is common and is increasing.
Cedars-Sinai neuroscience investigators have found that Alzheimer's disease affects the retina -- the back of the eye -- similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer's disease years before patients experience symptoms.
In this issue of JCI Insight, researchers at Cedars-Sinai Medical Center adapted a noninvasive retinal imaging approach to characterize amyloid-β deposition, the pathological hallmark of Alzheimer's disease, in the retinas of patients and healthy controls. This imaging enabled detection and quantification of amyloid-β, revealing increased deposits in Alzheimer's patients compared to controls. These results demonstrate the feasibility of this approach as a tool for earlier Alzheimer's diagnosis and intervention.
A new simulation of the dementia epidemic estimates the economic impact the disease has on households and public insurance programs and provides a tool for projecting the impact that different interventions could have.
Working with fruit flies, scientists have identified different labels that attract and control specific nerves. In theory, the 'right' labels may re-form nervous connections if delivered to the site of injury.
