Review highlights potential strategies for treatment of Down syndrome, AD

Down syndrome (DS) is the most common genetic disorder in live born children arising as a consequence of a chromosomal abnormality. It occurs as a result of having three copies of chromosome 21, instead of the usual two. It causes substantial physical and behavioral abnormalities, including life-long cognitive dysfunction that can range from mild to severe but which further deteriorates as individuals with DS age.

Unpaid caregivers provided an estimated $202 billion in dementia care in 2010

NPR reports unpaid caregiver costs for those with dementia was an estimated $202 billion in 2010 alone. In other news, the income of Massachusetts' elderly covers only 60 percent of living expenses, and at the Mayo Clinic, researchers are trying to learn more about the effects of old age.

Study offers hope for novel approach to prevent AD

As scientists struggle to find an effective way to prevent Alzheimer's disease, researchers at the University of Wisconsin-Madison may have found a new approach to interrupting the process that leads to the devastating disease.

New method for creating nanofibers could improve drug delivery methods

A new method for creating nanofibers made of proteins, developed by researchers at Polytechnic Institute of New York University (NYU-Poly), promises to greatly improve drug delivery methods for the treatment of cancers, heart disorders and Alzheimer's disease, as well as aid in the regeneration of human tissue, bone and cartilage.

New data on how genes and age influence AD plaque deposition

When 225 researchers from around the world convened in Miami to exchange the latest on β amyloid positron emission tomography in January, there was a palpable sense of urgency. At the 6th Annual Human Amyloid Imaging (HAI) Conference, the possibility of approval, potentially within months, of the first amyloid-scanning compound for clinical use hung over the room.

Researchers refute widely accepted hypothesis about causative step in ALS

In science, refuting a hypothesis can be as significant as proving one, all the more so in research aimed at elucidating how diseases proceed with a view toward preventing, treating, or curing them. Such a discovery can save scientists from spending precious years of effort exploring a dead end. In a study published in the Proceedings of the National Academy of Sciences, Munich-based researchers refute a widely accepted hypothesis about a causative step in neurodegenerative conditions.

New portable device can quickly diagnose infectious disease

Infectious diseases can spread very rapidly, so quickly identifying them can be crucial to stopping an epidemic. However, current testing for such diseases can take hours and days. But not for much longer.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

Brain mitochondria are dysfunctional in early-stage Alzheimer's

Mitochondria -- subunits inside cells that produce energy -- have long been thought to play a role in Alzheimer's disease. Now Mayo Clinic researchers using genetic mouse models have discovered that mitochondria in the brain are dysfunctional early in the disease.

Springer adds 6 new quarterly clinical review journals to medicine portfolio

Springer is adding six new quarterly clinical review journals to its existing medicine portfolio in March 2012. These new journals will expand the publisher's medical specialty coverage, focusing on dermatology, geriatrics/gerontology, nutrition, obesity, obstetrics/gynecology and respiratory care.

Bayer receives FDA approval for lower dose formulation of ANGELIQ

Bayer HealthCare Pharmaceuticals Inc. today announced that the U.S. Food and Drug Administration (FDA) has approved a lower dose formulation of ANGELIQ (drospirenone and estradiol) tablets to treat moderate to severe vasomotor symptoms due to menopause in women who have a uterus.

Walnuts associated with better memory scores and cognitive function

Do you recall what you ate for breakfast today or dinner last night? According to new research, you may have a better chance of remembering if you include walnuts. Recent findings published in the Journal of Alzheimer's Disease report walnut consumption in a Mediterranean diet is associated with better memory scores and cognitive function.

Alzheimer's disease drugs may act like a bad electrician

Alzheimer's disease drugs now being tested in clinical trials may have potentially adverse side effects, according to new Northwestern Medicine research. A study with mice suggests the drugs could act like a bad electrician, causing neurons to be miswired and interfering with their ability to send messages to the brain.

AAN, ALS Association announce creation of Richard Olney Clinician Scientist Development Award

The American Academy of Neurology Foundation and The ALS Association are announcing the creation of the Richard Olney Clinician Scientist Development Award in ALS, named after Richard K. Olney, MD, a leading neurologist and pioneer in clinical ALS research who died late last month of ALS, also known as amyotrophic lateral sclerosis, or Lou Gehrig's disease.

Targeting O-GlcNAcase enzyme with inhibitors might treat Alzheimer's

Slowing or preventing the development of Alzheimer's disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein's sugar levels are maintained.

Mantra-based meditation shows promise against age-associated cognitive impairment

Researchers at Thomas Jefferson University Hospital determined that mantra-based meditation can have a positive impact on emotional responses to stress, fatigue and anxiety in adults with memory impairment and memory loss.

DKR Fund for Alzheimer's research launches today

The Darrell K Royal Fund for Alzheimer's Research was launched today at an Interim Joint Committee hearing on Alzheimer's Disease (AD) in the Texas Senate Chamber. The DKR Fund is named after legendary Texas football coach Darrell Royal and was created to facilitate research and care for Texans to attempt to cure AD in our lifetimes.

Single dose of Ritalin may raise awareness of mistakes: Study

The study, by Dr Rob Hester from the Department of Psychological Sciences and colleagues at the Queensland Brain Institute, investigated how the brain monitors ongoing behavior for performance errors – specifically failures of impulse control. This study found that a single dose of methylphenidate (Ritalin) results in significantly greater activity in the brain’s error monitoring network and improved volunteers’ awareness of their mistakes.

Low levels of omega-3 in blood ‘ups’ risk of dementia and brain aging: Study

Researchers looked at 1,575 adults who averaged 67 years old and had no signs of dementia and had not had a stroke. They were given MRI brain scans and a battery of tests to measure memory and thinking abilities; they also had blood drawn to check the level of docosahexaenoic acid (DHA) or omega-3 fatty acids in their red blood cells. Those with the lowest levels of omega-3s showed signs of accelerated aging. They had lower brain volume, indicating shrinkage comparable to two additional years of aging. Compared with those with the highest blood levels of omega-3s, they scored lower on cognitive tests measuring such things as memory, problem solving, abstract thinking and multi-tasking.
