Hearing aid use improves cognitive function in hearing-impaired older adults

A study conducted by researchers at Columbia University Medical Center found that older adults who used a hearing aid performed significantly better on cognitive tests than those who did not use a hearing aid, despite having poorer hearing. The study was published online in the American Journal of Geriatric Psychiatry.

Dopamine D2 receptor gene can prolong lifespan

Researchers at the University at Buffalo Research Institute on Addictions have discovered how a gene in the brain's dopamine system can play an important role in prolonging lifespan: it must be coupled with a healthy environment that includes exercise.

First breakthrough in gene therapy against aging

In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.

UK research allays fears over dramatic increases in dementia incidence

Research conducted in the UK has found a 20% drop in the incidence of dementia over the past 2 decades, leading to an estimated 41,000 fewer cases per year in people aged 65 years and older than previously expected.

Wellderly study finds link between cognitive decline genes and healthy aging

An eight-year-long accrual and analysis of the whole genome sequences of healthy elderly people, or "Wellderly," has revealed a higher-than-normal presence of genetic variants offering protection from cognitive decline, researchers from the Scripps Translational Science Institute (STSI) reported today in the journal Cell.

Higher levels of neighborhood greenness linked to lower chronic disease risk

A new study of a quarter-million Miami-Dade County Medicare beneficiaries showed that higher levels of neighborhood greenness, including trees, grass and other vegetation, were linked to a significant reduction in the rate of chronic illnesses, particularly in low-to-middle income neighborhoods.

Study finds low prevalence of vascular risk among Southwest US population

In a newly published, pilot study in the journal Ethnicity & Disease, researchers report a relatively low prevalence of vascular risk among participants of the Southwest Heart Mind Study, especially among those treated for hypertension and hyperlipidemia despite overweight and obesity.

Researchers use highly accurate biomarker to measure aging in HIV infected patients

Thanks to combination antiretroviral therapies, many people with HIV can expect to live decades after being infected. Yet doctors have observed these patients often show signs of premature aging.

Subtle changes in protein-coding gene may cause different genetic disorders

It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."

TAVR procedure could provide improved health outcomes for inoperable patients

A novel procedure for heart valve replacement surgery could provide improved health outcomes for patients who cannot have open heart surgery, as well as being a cost effective alternative.

Dog ownership and walking increase physical health among older adults

The Centers for Disease Control and Prevention recommends that adults of all ages should engage in 150 or more minutes of moderate physical activity per week. Among adults 60 years of age or more, walking is the most common form of leisure-time physical activity because it is self-paced, low impact and does not require equipment.

Using Proteomics to Understand Alzheimer’s: An Interview with Dr Renã Robinson

In our bioanalytical mass spectrometry lab we use proteomics techniques to try to understand more about Alzheimer's disease. The primary thrust of our research is that we're interested in understanding the changes that take place outside of the brain and how those correlate with what's taking place inside the brain

New diagnostic approach may help physicians more efficiently screen for dementia

A tiered diagnostic approach that incorporates clinical, imaging and laboratory data may help physicians more efficiently screen for neurodegenerative disorders such as dementia, according to the consensus of a multi-disciplinary panel of experts.

Study shows beneficial effect of hNSC transplantation for TBI

Traumatic brain injury (TBI) is a major cause of mortality and morbidity, often causing lifelong disability for those who survive. Treatment is limited to supportive care, but stem cell therapy has received recent attention as a way to promote recovery for injuries to the central nervous system (CNS). In this study, researchers transplanted human neural stem cells (hNSCs) into the brains of mice modeled with TBI to investigate whether the hosts' immune systems and the stem cells acting in concert would enhance repair.

Almost half of all long-stay nursing home residents visit ED every year regardless of cognitive status

A new study from the Indiana University Center for Aging Research and the Regenstrief Institute has found that almost half of all long-stay nursing home residents experience at least one transfer to an Emergency Department over the course of a year regardless of their cognitive status. While a high percentage of long-stay nursing home residents were sent to the ED, only about a third of these individuals were subsequently admitted to the hospital.

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Low doses of bisphenol A can affect development of metabolism, reproductive and nervous systems

If rats are exposed to bisphenol A in low doses during early development it can lead to reduced sperm count, obesity and changes to breast development and behaviour. These are some of the findings of a new study from the National Food Institute, Technical University of Denmark. The results support previous animal studies, which have shown that low doses of bisphenol A can affect development of the metabolism as well as the reproductive and nervous systems.

Study investigates usefulness of plasma levels as biomarker for AD

A Centre for Healthy Brain Ageing paper published in Current Alzheimer Research presents the first detailed study of the relationship between plasma levels of two amyloid beta peptides (Aβ1-40 and Aβ1-42), brain volumetrics (measures studying the size of brain, which shrinks with Alzheimer's disease) and cognitive performance in an investigation of the usefulness of plasma levels as a biomarker for Alzheimer's disease (AD).

Radiotherapy needs likely to increase in all European countries by 2025

The demand for radiotherapy across all European countries will increase by an average of 16% between 2012 and 2025, with the highest expected increase being for prostate cancer cases (24%), according to a new study published in Radiotherapy and Oncology.
