Researchers find fatty acid deposits in brains of Alzheimer's patients

People with Alzheimer's disease have fat deposits in the brain. For the first time since the disease was described 109 years ago, researchers affiliated with the University of Montreal Hospital Research Centre (CRCHUM) have discovered accumulations of fat droplets in the brain of patients who died from the disease and have identified the nature of the fat.

Brain cells in Parkinson's disease die prematurely, burning out like an overheating motor

The death of brain cells in Parkinson's disease may be caused by a form of cellular energy crisis in neurons that require unusually high quantities of energy to carry out their job of regulating movement, researchers at the University of Montreal reported today.

Isolated tauopathy ‘surprisingly common’ in AD dementia

A study shows that about a quarter of people with clinically diagnosed mild or moderate Alzheimer’s disease have only minimal β-amyloid deposition on autopsy.

Discovery could help in development of novel cancer-selective viral therapies

Every organism--from a seedling to a president--must protect its DNA at all costs, but precisely how a cell distinguishes between damage to its own DNA and the foreign DNA of an invading virus has remained a mystery.

Dementia sufferers may begin to lose awareness of memory problems 2-3 years before onset

People who will develop dementia may begin to lose awareness of their memory problems two to three years before the actual onset of the disease, according to a new study published in the August 26, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology.

UCSF study reveals molecular timing mechanism of stem cells

UC San Francisco researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue.

Individuals having high blood levels of two closely related proteins experience few adverse health events

Individuals previously diagnosed with heart disease may be less likely to experience heart failure, heart attacks, or stroke, or to die from these events, if they have higher blood levels of two very closely related proteins, according to a new study led by a UC San Francisco research team.

Omega-3 supplements fail to slow cognitive decline in older persons, NIH clinical study shows

While some research suggests that a diet high in omega-3 fatty acids can protect brain health, a large clinical trial by researchers at the National Institutes of Health found that omega-3 supplements did not slow cognitive decline in older persons. With 4,000 patients followed over a five-year period, the study is one of the largest and longest of its kind.

Physical activity improves cognitive flexibility in older adults

One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say.

MIPT scientists reveal that weak gamma radiation doses prolong life of female fruit flies

Scientists at MIPT have revealed that weak doses of gamma radiation prolong the life of drosophila flies (fruit flies), and that the effect is stronger in females than in males. These findings could reveal the genes that enable the prolongation of life and in the future lead to the creation of a means to prevent aging in humans.

Alpha lipoic acid can stimulate telomerase with positive effects in mouse model of atherosclerosis

In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are both a sign of aging and contribute to it. Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis.

Number of dementia patients stabilizing experts claim

Risk of dementia may be falling due to improved education and living conditions, and better prevention and treatment of vascular diseases, highlighting the need for policies to improve health across the life course.

Researchers evaluate use of human fetal progenitor tenocyte to repair tendon injuries

Tendon injuries, especially those acquired while engaging in sports, are not easily healed due to the fibrous nature of tendon tissues which transmit forces from muscle to bone and protect surrounding tissues against tension and compression. Tendon injuries to wrists, knees, elbows and rotator cuffs, often from over use when playing golf or tennis, are increasingly common for both professional and amateur athletes ("weekend warriors") alike.

Stress hormone cortisol tied to thinking problems in healthy older people

Testing the saliva of healthy older people for the level of the stress hormone cortisol may help identify individuals who should be screened for problems with thinking skills, according to a study published in the August 19, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology.

Rowan study reveals how exposure to Hurricane Sandy impacts mental health among older adults

Researchers from the Rowan University School of Osteopathic Medicine presented findings at the "2015 Hurricane Sandy Conference: Translating Research into Practice," showing that strong neighborhood relationships reduced the incidence of symptoms of post-traumatic stress disorder (PTSD) among older adults exposed to Hurricane Sandy, the superstorm that devastated the Northeast United States.
