People with multiple sclerosis (MS) gradually develop increasing functional impairment. Researchers have now found a possible explanation for the progressive course of the disease in mice and how it can be reversed. The study can prove valuable to future treatments.
A new Alzheimer's study found that impaired blood flow in the brain is correlated with the buildup of tau tangles, a hallmark indicator of cognitive decline.The work suggests that treatments targeting vascular health in the brain -- as well as amyloid plaques and tau tangles -- may be more effective in preserving memory.
The first systematic review of how the severity of infectious diseases changes with age suggests that the human immune system might start to lose the ability to protect against infections earlier than previously thought, according to new research.
Older adults with severe apathy, or lack of interest in usual activities, may have a greater chance of developing dementia than people with few symptoms of apathy, according to a new study.
Scientists have found that the main sensor protein enabling our sense of touch also underlies the feeling of having a full bladder and makes normal bladder function possible. The discovery marks a key advance in basic neurobiology and may also lead to better treatments for bladder control and urination problems, which are common especially among the elderly.
Two research teams sought to understand sedentary lifestyles, with one study finding that even light physical activity, including just standing, can benefit health, and the other that Americans are sitting too much.
Researchers have found out how cells can recover their development and longevity after damage by UV. The discovery may enable new therapies against premature aging.
Scientists have estimated that the age of an individual does not indicate how likely they are to be infected by SARS-CoV-2. However, development of symptoms, progression of the disease, and mortality are age-dependent.
There are concerns that exposure to general anesthesia during surgery may contribute to an increased risk of Alzheimer's disease. To investigate, researchers compared exposure to general anesthesia versus regional anesthesia during elective surgery, looking for potential links to the development of dementia.
No one knows for sure how long they will live. A new study, however, suggests that leukocyte telomere length may offer some key insights into a woman's longevity and further demonstrates how maternal age at birth of last child affects telomere length and long-term health.
After examining the brainstems of 186 young Mexico City residents aged between 11 months and 27 years of age, researchers, found markers not only of Alzheimer's disease, but also of Parkinson's and of motor neuron disease (MND) too. These markers of disease were coupled with the presence of tiny, distinctive nanoparticles within the brainstem - their appearance and composition indicating they were likely to come from vehicle pollution.
A new article describes the discovery of several promising small molecules that appear to reduce cellular stress in mouse skin cells and could lengthen life.
Fecal transplants could one day be used to restore cognitive decline among the elderly - according to new research. A new study shows how fecal transplants from older to younger mice altered their gut microbiome, which in turn impacted their spatial learning and memory. The research team hope the reverse could also be true, and one day used as a therapy to restore cognitive function in older people.
A new, rare genetic form of dementia has been discovered by researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies.
A research team has revealed that narrow-range ultraviolet (UV) irradiation using light emitting diodes (LEDs) safely increases serum vitamin D levels in aging mice and thereby prevents the loss of their bone and muscle mass.
Irregular and long menstrual cycles in adolescence and adulthood are associated with a greater risk of early death (before age 70), a new study finds.
A new analysis, using information from the COVID Symptom Study app and patients admitted to St Thomas' Hospital in London, has shown that delirium -- a state of acute confusion associated with a higher risk of serious illness and death -- is a key symptom of COVID-19 in frail, older people.
It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases. Now scientists have some of the first evidence that at a younger age at least, senescent cells show up quickly after a major injury and are protective.
A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn. The discovery has implications for wound treatment and preventing some of the aging process in skin. Researchers identified a factor in the skin of baby mice controlling hair follicle formation. When it was activated in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps.
Scientists have measured the molecular footprint that aging leaves on various mouse and human tissues. Using the data, they have identified likely regulators of this central process.
