Alzheimer's Disease News and Research

RSS

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Researcher develops procedures for defining preclinical stages of Alzheimer's disease

Both of Andrew Kiselica's grandfathers developed dementia when he was in graduate school. As Kiselica was going through neuropsychology training in graduate school, he saw his mother's father become unable to walk or speak due to severe dementia.

Low levels of hydrogen peroxide can slow down cell aging

High levels of reactive oxygen species, called oxidants, are detrimental to cells in all organisms and have been associated with ageing.

Genetically edited form of herpes simplex virus outperforms key vaccine candidate

A genetically edited form of a herpes simplex virus -- rewired to keep it from taking refuge in the nervous system and eluding an immune response -- has outperformed a leading vaccine candidate in a new study from the University of Cincinnati, Northwestern University and the University of Nebraska-Lincoln.

LipiDiDiet project shows positive effects of nutrient intervention in early Alzheimer’s disease

Trial participants who received a multinutrient formulation over an extended period of time showed a significantly less rapid deterioration in cognitive performance than the patients in a control group, who received only a placebo.

Researchers use AI tool to study the dynamics behind cancer, Alzheimer’s disease

With the help of artificial intelligence (AI), scientists from the University of Copenhagen have solved a crucial issue that, to date, has been a major barrier to significant protein research into the dynamics behind various diseases, like Parkinson’s, Alzheimer’s, cancer, and also in the development of novel gene-editing techniques and sustainable chemistry.

Metabolite of dietary soy may decrease key risk factor for dementia

A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia--with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.

Researchers uncover a new cellular mechanism for disposing of misfolded proteins

About 30 years ago, Dr. Richard Sifers set out on a journey to discover why people with a rare condition known as alpha1-antitrypsin (AAT) deficiency present with high variation in the severity of liver disease.

Enzyme SSH1 impairs disposal of damaged tau and mitochondria leaking toxins

In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.

Researchers discover how synapses find energy to support intense neural conversations

Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses.

Vacuolar Tauopathy: New, rare genetic form of dementia discovered

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine 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. The study was published today in Science.

Epigenetic alterations drive late-onset Alzheimer's disease

New findings suggest that late-onset Alzheimer's Disease is driven by epigenetic changes -- how and when certain genes are turned on and off -- in the brain. Results were published today in Nature Genetics.

Study sheds light on how membrane proteins could be influenced by lipids

The cell membrane, the wall-like boundary between the cell interior and its outside environment, is primarily made up of two kinds of biomolecules: lipids and proteins.

Biomarker for diagnosis of neurodegenerative diseases identified in the eye

A new study led by Boston Medical Center researchers indicates a well-known biomarker that serves as a marker for earlier diagnosis of neurodegenerative diseases is now detectable in the eye.

Alzheimer's disease may be driven by overactivation of fructose made in the brain

New research released from the University of Colorado Anschutz Medical Campus proposes that Alzheimer's disease may be driven by the overactivation of fructose made in the brain.

Star-shaped brain cells are essential for blood-brain barrier health, shows study

Hard skulls help protect our brains from physical injuries.In addition to a tough outer shell, brains have internal defenses, including a powerful shield called the blood-brain barrier that defends brain cells from substances in the bloodstream that are toxic and dangerous to nerve cells. If the blood-brain barrier is breached, then health problems arise.

Protein aggregation reduces elasticity of blood vessels during aging

Deposits of a protein called "Medin", which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia.
