Two new studies now suggest that a noninvasive eye scan could soon be used to catch Alzheimer’s disease early. A simple eye scan may soon detect Alzheimer’s in a matter of seconds. The world’s population is aging rapidly and the prevalence of Alzheimer’s disease is on the rise. For this reason, the need for efficient
Scientists have revealed that an enzyme that is present in the liver and kidneys limits the activity of a molecule that plays a role in cell metabolism and longevity. Their research suggests that blocking this enzyme could be a way to preserve the health of these organs. Increasing levels of a so-called anti-aging molecule may
People do not know exactly what causes Parkinson’s disease, but there is evidence that certain factors may make it more likely to occur. Read on to find out more about genetic factors and environmental exposures that might make Parkinson’s disease (PD) more likely to appear in some people. Some of these are unavoidable, but for
Parkinson’s disease is a complex condition with a wide range of symptoms. There is currently no cure, but treatment can help relieve symptoms, slow disease progression, and improve quality of life. Treatment approaches include medication, surgery, alternative and complementary therapies, occupational therapy, and speech therapy. The symptoms of Parkinson’s disease (PD) vary widely so no
Parkinson’s disease is a neurological condition with a wide range of effects, including problems with movement, blood pressure and thinking, and mood, sensory, and sleep difficulties. The symptoms of Parkinson’s disease (PD) usually begin gradually, and they affect each person differently. The symptoms a person has will vary widely, regardless of how severe they are
An increasing number of recent studies are asking an important question: Do gut bacteria hold the key to healthy aging? New research, recently presented at the London Microbiome Meeting, brings us closer to the answer. Research presented at the London Microbiome Meeting zoomed in on the role of bacteria for human health and aging. In
Regular exposure to stress can impact our physical and mental health, but how does it actually affect our brains? One new Harvard Medical School study answers that question. According to new research, high levels of stress hormones can impact how well the brain functions. Stress — especially when we experience it on a regular basis
Being physically active for at least 2.5 hours per week could delay decline in mental capacity in a rare form of Alzheimer’s disease that starts years earlier, according to recently published research. Evidence suggests that a person can alter risk factors for Alzheimers’s disease by adopting a healthy lifestyle. The finding comes from an international
A new study has found that people living with major depressive disorder are biologically older than people without depression, and that childhood trauma exacerbates this effect. The results illuminate the epigenetic mechanisms that might explain this discrepancy. Depression may cause premature aging, a recent study has suggested. Major depression is one of the most common
Because there is no cure for dementia, accurately predicting who will go on to develop it is vital to minimize its impact. According to a new review, apathy may hold the key. A new study investigates apathy and its role in dementia onset. Dementia overwhelmingly impacts older adults. Although scientists know about some risk factors,
Dementia and Alzheimer’s disease are similar but not the same. Dementia is a general term and has many different types, of which Alzheimer’s is one. There is sometimes confusion between the two because people often use the terms interchangeably. Dementia is an umbrella term used to describe a set of symptoms that broadly affect cognitive
New research, published in the journal Annals of the Rheumatic Diseases, shows that an innovative blocking agent can stop the degeneration of the cartilage when injected into the joints. Osteoarthritis often affects the knee joints. Osteoarthritis is a progressive condition that affects the bones and cartilage within the joints. Although it occurs most often in
Previous research suggested that hearing loss and abnormalities in the eye are tied to memory loss and a higher Alzheimer’s risk. New evidence now indicates that addressing hearing and sight problems can slow down cognitive decline. Opting for hearing aids and cataract surgery can make a big difference when it comes to slowing down cognitive
New evidence suggests that atrial fibrillation, in which the heart has an irregular beat, is linked to an increased risk of dementia. This knowledge, however, also indicates a potential preventive strategy, researchers show. An irregular heartbeat speeds up the rate at which cognitive function deteriorates, but there may be an easy way to address this.
People with a diagnosis of dementia can also face depression. For this reason, they may end up taking antidepressant drugs. Now, a study has found that these drugs may be able to treat not just depression, but dementia itself. A new study tests out the potential of antidepressants to tackle dementia mechanisms in the brain.
It may be harder for cells to repair themselves as the body ages, and this may play a role in the development of chronic obstructive pulmonary disease, otherwise known as COPD. Younger people are still at risk, but increasing age may mean more lung damage and exposure to risk factors, and so a higher risk.
Ketogenic, or keto, diets are low-carb and fat-rich, and many people who follow such regimens do it to shed excess weight. However, a keto diet may bring other benefits, too. In particular, it may help keep the brain healthy and young, as new research in mice seems to suggest. Can a keto diet protect brain
Vitamins are nutrients that when synthesized or assimilated in the right quantities support our health and well-being. A new review suggests that a set of known and newly categorized vitamins can help prolong a person’s lifespan, and promote health well into old age. A series of crucial nutrients may be ‘longevity vitamins’ that help fend
The herpes virus could account for at least half of Alzheimer’s cases, according to a new review of the findings of three recent studies examining links between Alzheimer’s and herpes. Infection with the herpes simplex virus may boost the likelihood of developing Alzheimer’s, researchers suggest. The new paper, published in the Frontiers in Ageing Neuroscience
In our increasingly aging society, it is worth asking: what can we do to ensure that we don’t just live longer lives, but also healthier ones? New research suggests one possible answer — eat more seafood! Seafood contains fatty acids that may help people age healthily. A new study, led by Heidi Lai from the
A new, large-scale study finds that even extreme levels of fitness increase lifespan — particularly in older people. A new study finds that exercise, even at extreme levels, prolongs life for seniors. Exercise is widely considered to benefit health, but is there such a thing as too much exercise? Some recent studies suggest so. For
According to a team of Swedish-based researchers, breathing through the nose may help memory storage and consolidation. These findings are published in The Journal of Neuroscience. The way we breathe affects our memory in mysterious ways. Recently, neuroscientists have been scrutinizing the link between smell and memory. Some have suggested that a damaged sense of
