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.

Increased Sirt1 expression protects against neurodegeneration in HD mouse model

Treatment that increases brain levels of an important regulatory enzyme may slow the loss of brain cells that characterizes Huntington's disease (HD) and other neurodegenerative disorders.

Experts argue about dementia detection in primary care practice at AFA-ADDF meeting

Many people with dementia don't realize they have the disease until it's at an advanced stage, when everyone can tell something is wrong. Other people might start forgetting dates or names and worry they have dementia, yet their memory problems are just a normal consequence of aging.

GE Healthcare's MIND campaign goes online for patients with neurodegenerative diseases

GE Healthcare's MIND campaign is going online to give those affected by neurodegenerative diseases like Alzheimer's or other forms of dementia and parkinsonian syndromes a platform to share their stories.

Decision support tool for objective diagnostics of Alzheimer's

European PredictAD project, lead by Principal Scientist Jyrki Lötjönen from VTT Technical Research Centre of Finland, has developed a decision support tool for objective diagnostics of Alzheimer's disease.

New drug candidate may halt mental decline of Alzheimer's

A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer's disease, based on the findings of a study published today in PLoS one.

Magnetic stimulation of brain nerve cells may speed up recovery from hemispatial neglect

Imagine waking up and being unable to see or recognize anything on the left side of your body. This condition, called hemispatial neglect, is common after a stroke that occurs on the right side of the brain. The current treatment of attention and concentration training using computer and pencil-and-paper tasks is inadequate.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Molecular signature indicative of hypoxia predicts progression to AD

A study led by Research Professor Matej Ore-ič from VTT Technical Research Centre of Finland suggests that Alzheimer's disease is preceded by a molecular signature indicative of hypoxia and up-regulated pentose phosphate pathway.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Acetylcholine can weaken synaptic connections between neurons in brain

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories.

Link between high tau levels and worse outcome after head trauma

High levels of tau protein in fluid bathing the brain are linked to poor recovery after head trauma, according to a study from Washington University School of Medicine in St. Louis and the Fondazione IRCCS Ca Granda-Ospedale Maggiore Policlinico in Milan, Italy.

GW scientist to identify molecular mechanisms that define embryonic OE stem cells

Anthony-Samuel LaMantia, PhD, professor in the Department of Pharmacology and Physiology and Director of the GW Institute for Neuroscience in the School of Medicine and Health Sciences has been awarded a grant from the National Institutes of Health to identify molecular mechanisms that define embryonic olfactory epithelium (OE) stem cells.

Brain atrophy is evident in Parkinson's patients with MCI

Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Intertwined diseases may both contribute to cognitive decline in Parkinson's

A method of classifying brain atrophy patterns in Alzheimer's disease patients using MRIs can also detect cognitive decline in Parkinson's disease, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Researchers also found that higher baseline Alzheimer's patterns of atrophy predicted long-term cognitive decline in cognitively normal Parkinson's patients.

Study describes new method that synthesizes novel anti-HIV protein

The most abundant and important molecules in all living organisms are proteins; after all they manage to participate in every single one of life's essential reactions. So it is easy to see why scientists have been making such a fuss trying to learn how to synthesise them in laboratory as this would provide them with a tool of extraordinary potential. Unfortunately, this has not proved easy.

Roundup: Iowans question Wellmark premium hikes; Fla. Medicare audit; Mich. nursing home scandals

The Wellmark Blue Cross/Blue Shield vice president faced dozens of angry customers and tried to explain why the health insurer wants to increase their premiums by 9.4 percent. ... Barbed questions flew throughout the hearing before the state insurance commissioner, who will decide whether to grant Wellmark's proposed increase for 86,000 Iowans who buy their own insurance policies.

New method to design Alzheimer's antibodies

Researchers at Rensselaer Polytechnic Institute have developed a new method to design antibodies aimed at combating disease. The surprisingly simple process was used to make antibodies that neutralize the harmful protein particles that lead to Alzheimer's disease.

Tips to help ease caregiver's burden during holiday season

More five million Americans suffer from Alzheimer's disease or another form of dementia and over 70 percent of those individuals are cared for in their homes by a spouse or other family member. Stress, anxiety and burnout are never far from the doorsteps of these caregivers as they often juggle the responsibilities of providing daily care with the added demands of working, maintaining a household, or raising children. The holiday season can intensify these daily burdens, but too often caregivers don't know how to ask for help and friends and family members aren't sure of how to lend a hand.
