Riluzole drug can reverse key genetic changes linked to Alzheimer's disease

Aging takes its toll on the brain, and the cells of the hippocampus--a brain region with circuitry crucial to learning and memory--are particularly vulnerable to changes that can lead to Alzheimer's disease or cognitive decline. With the hope of counteracting the changes that can lead to these two conditions, researchers at Rockefeller University and their colleagues have begun examining the effects of a drug known to affect this circuitry.

Important changes in social lives of older adults indicate cognitive decline

Small changes in the social lives of older people are early red flags showing that their thought processes and brain functioning could be on the decline. This is according to Ashwin Kotwal of Brigham and Women's Hospital in the US, who led a study¹ in the Journal of General Internal Medicine, published by Springer.

High-intensity exercise, group activity reduce depression among older dementia patients

Both a high-intensity functional exercise programme and a non-exercise group activity, conducted among older care facility residents with dementia, reduced high levels of depressive symptoms. However, exercise had no superior effect on depression, according to a dissertation from Umea University.

Community-based social groups could support people with early-onset dementia

Community-based social groups could play a crucial role in empowering people with early-onset dementia, according to new UBC research.

Study shows cannabinoid type 2 receptor plays vital role in signal processing of the brain

The cannabinoid type 2 receptor - also called "CB2 receptor" - is a special membrane protein. Its function is to receive chemical signals that control cellular activity. "Until now, this receptor was considered part of the immune system without function in nerve cells.

Snapshots of NMDA receptor activation may help in novel drug design

Structural biologists at Cold Spring Harbor Laboratory and Janelia Research Campus/HHMI, have obtained snapshots of the activation of an important type of brain-cell receptor. Dysfunction of the receptor has been implicated in a range of neurological illnesses, including Alzheimer's disease, Parkinson's disease, depression, seizure, schizophrenia, autism, and injuries related to stroke.

Researchers one step closer to understanding disease origin

Researchers are one step closer to understanding the genetic and biological basis of diseases like cancer, diabetes, Alzheimer's and rheumatoid arthritis - and identifying new drug targets and therapies - thanks to work by three computational biology research teams from the University of Arizona Health Sciences, University of Pennsylvania and Vanderbilt University.

Nuplazid (pimavanserin) tablets approved to treat hallucinations and delusions

The U.S. Food and Drug Administration today approved Nuplazid (pimavanserin) tablets, the first drug approved to treat hallucinations and delusions associated with psychosis experienced by some people with Parkinson's disease.

Discovery of shared biological properties among DNA variants may help identify new therapeutic targets

The discovery of shared biological properties among independent variants of DNA sequences offers the opportunity to broaden understanding of the biological basis of disease and identify new therapeutic targets, according to a collaboration between the Perelman School of Medicine at the University of Pennsylvania, the University of Arizona Health Sciences, and Vanderbilt University. The group published their findings this month in npj Genomic Medicine.

People with TBI may have long-term sleep disturbances

People who have had a traumatic brain injury (TBI) may still have sleep problems a year and a half after being injured, according to a study published in the April 27, 2016, online issue of Neurology, the medical journal of the American Academy of Neurology. In addition, people with TBI may also be unaware of just how much their sleep is disturbed.

New study reveals increased risk of dementia in patients with rosacea

A new study has uncovered an increased risk of dementia--in particular Alzheimer's disease--in patients with rosacea. Importantly, the risk was highest in older patients and in patients where rosacea was diagnosed by a hospital dermatologist. The findings are published in the Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society.

Rapamycin drug could target neural damage linked to Leigh syndrome

Salk Institute scientists showed how an FDA-approved drug boosts the health of brain cells by limiting their energy use. Like removing unnecessary lighting from a financially strapped household to save on electricity bills, the drug--called rapamycin--prolongs the survival of diseased neurons by forcing them to reduce protein production to conserve cellular energy.

Researchers test potential positive effects of micro-injury in mice modeled with AD

Researchers testing the potential positive effects of "micro-injury" by brief insertion of a small needle into the hippocampal region of mice modeled with Alzheimer's disease (AD) have found that the procedure not only stimulated the hippocampus into regenerative activity, but also reduced β-amyloid plaques, a hallmark of AD.

University of Leicester-led study finds way to reverse symptoms of Parkinson’s and Alzheimer’s

A five-year study by an international team led from the University of Leicester has found a way of ‘reversing’ symptoms of neurodegenerative diseases such as Parkinson’s and Alzheimer’s – using fruit flies as test subjects.

Single season of contact sports can cause measurable brain changes

Repeated impacts to the heads of high school football players cause measurable changes in their brains, even when no concussion occurs, according to research from UT Southwestern Medical Center's Peter O'Donnell Jr. Brain Institute and Wake Forest University School of Medicine.

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.

Study on HDAC enzymes could lead to development of better drugs for treatment of cancer, Alzheimer’s

New knowledge about the mechanism of specific protein complexes in the body could help in the development of better drugs for the treatment of diseases such as cancer and Alzheimer’s, according to research led by the University of Leicester.

Type 2 diabetes can lead to hearing impairment

A review of studies of possible linkages between type 2 diabetes and hearing impairment concludes there is compelling evidence that diabetes can damage the auditory system, and that clinicians should include hearing testing in managing type 2 diabetes. The survey results were published in an article titled, "Type 2 Diabetes and Hearing Impairment" in the journal, Current Diabetes Reports.

Fructose common in western diet can damage brain genes

A range of diseases -- from diabetes to cardiovascular disease, and from Alzheimer's disease to attention deficit hyperactivity disorder -- are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that's common in the Western diet, in a way that could lead to those diseases.

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.
