Aging

Researchers investigated what factors play a role in cognitive decline in retirement, emphasizing the importance of staying mentally active. Previous research has shown that as people age and retire there is a decline in cognition due to less or no involvement in mental activities. The rate of cognitive decline varies individually and may be caused

A recent study investigated the association between olive oil and decreased risk of aging-related diseases.  Olive oil is a primary source of fat in the Mediterranean diet. It consists of monosaturated fatty acids (MUFAs), the healthy fat that lowers cholesterol levels. It is rich in antioxidants, which help prevent cellular damage and decrease the risk

Can adopting a Mediterranean diet have further health benefits for older people? Frailty is one of the by-products of the aging process. As people get older, they naturally tend to become frailer and, as a result, are at an increased risk of inflammation and/or fractures. However, although frailty cannot be avoided completely, it can be

A new study examines the association between childhood trauma and dementia. As the global population continues to age, dementia prevalence is increasing. It’s estimated that by 2050, there will be close to 150 million dementia sufferers worldwide (1). This dementia time-bomb has led to greater research focus on the underlying causes of dementia. Although no

In a pilot study, researchers investigated the potential of regular aerobic exercise in Alzheimer’s disease prevention. Alzheimer’s disease is the most common type of dementia, a progressive brain condition that impairs memory, thought processes, and behavior. Dementia usually affects older people, although it is not a normal part of aging. With people living longer worldwide,

A new study explores whether a high-walnut diet can slow cognitive decline and preserve cognitive function in older adults. Thanks to increases in global life expectancy, the global prevalence of dementia is on the rise. Despite this, modern medicine remains poorly equipped to deal with the condition. Treatments for dementia focus on slowing disease progression

A new study investigates the link between air pollution and brain health by investigating the effects of in proximity to major roads. Air pollution is a growing problem around the world as various industries produce increasing amounts of carbon dioxide, methane, and other pollutants. These pollutants have detrimental effects on climate change, air quality, and

A recent study has supported the link between aluminum and familial Alzheimer’s disease and further explored how aluminum and amyloid-β are interlinked in the disease. Familial Alzheimer’s disease is a rare type of Alzheimer’s disease that is associated with three kinds of genetic mutations – amyloid precursor protein, presenilin-1, and presenilin-2. The link between aluminum

Previous research has suggested that there is a link between depression and tea drinking. Now, a new study is investigating this relationship further. Depression is common among older adults, with 7% of those over the age of 60 years reporting “major depressive disorder.” Accordingly, research is underway to identify possible causes, which include genetic predisposition,

Lowering an older person’s systolic blood pressure to 120 mmHg or lower reduces the risk of heart disease, but increases the chance of kidney changes. Share on PinterestOlder adults may need different guidelines for maintaining healthy blood pressure, new research suggests. In the United States, over half of the people aged 60 and over have

Everyone ages differently, but why is that? A team of researchers has pinpointed four “ageotypes” — main biological pathways for aging — that could help us answer that question. Share on PinterestThe identification of four ageotypes may help explain why our bodies age in different ways. Everyone ages, but not in the same way. Getting

A person may experience an itching sensation, or pruritus, on their face for a number of different reasons. Although pruritus can occur due to visible conditions, such as psoriasis or an insect bite, it might also indicate the presence of an underlying condition. This article will look at the different causes of pruritus on the

The symptoms of frontotemporal, or early onset, dementia can appear as early as age 40. Have researchers found a new way to treat this condition using antibiotics? Frontotemporal dementia, or frontotemporal lobar dementia, is an umbrella term that refers to a range of early onset dementias characterized by the progressive atrophying of the brain’s frontal

Brain atrophy refers to a loss of brain cells or a loss in the number of connections between brain cells. People who experience brain atrophy typically develop poorer cognitive functioning as a result of this type of brain damage. There are two main types of brain atrophy: focal atrophy, which occurs in specific brain regions,

Dehydration can cause headaches and several physiological issues, and older adults are most at risk of experiencing it. Does it also affect cognitive function, however? And might overhydration also affect mental performance? Share on PinterestRecent research set out to reveal whether or not hydration levels can affect cognitive performance in older adults. Dehydration can cause

Many researchers have argued that the accumulation of toxic beta-amyloid in the brain causes Alzheimer’s. However, a new study offers some evidence contradicting this sequence. Share on PinterestNew research is questioning the predominant hypothesis that a buildup of beta-amyloid causes Alzheimer’s disease. Alzheimer’s disease affects over 5.5 million people in the United States and millions

Although a vaccine for dementia is a long way down the road, researchers recently made a few tentative steps closer. The authors of a recent study in mice hope that in the coming years, they can move into human trials. Share on PinterestScientists believe that they are on the path to a vaccine against dementia.

Danish researchers have investigated whether exercise benefits Alzheimer’s patients, specifically those with accompanying mental health conditions. Although previous studies have shown that physical activity in middle-aged healthy, active adults has a positive effect on cognition in later years, there is no reliable evidence as to whether exercise is good for Alzheimer’s patients who have a

A new study looks at what keeps older adults from getting sufficient fluids to avoid negative health outcomes. Share on PinterestNew research stresses the importance of staying hydrated as we get older. Staying hydrated seems simple enough. Yet studies have shown that somewhere between about one-third and one-half of older adults may be dehydrated, increasing

Our genes alone do not determine our chances of developing Alzheimer’s disease, study finds. Our genes determine many of our physical characteristics such as the colour of our eyes. However, the role of genes in the development of various diseases such as cardiovascular disease, diabetes, neurodegenerative diseases such as Parkinson’s and Alzheimer’s disease, is an
