Current Screening Methods Miss Worrisome Number of Persons with Mild Cognitive Impairment

mri_brain_colorized.jpg

In a paper published in the current Journal of Alzheimer’s Disease, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System say existing screening tools for mild cognitive impairment (MCI) result in a false-negative error rate of more than 7 percent. These persons are misclassified as not having MCI based on standard screening instruments but actually do have MCI when more extensive testing is conducted.

Brain Scans of Dementia Patients with Coprophagia Showed Neurodegeneration

Coprophagia, eating one’s feces, is common in animals but rarely seen in humans. Mayo Clinic researchers reviewed the cases of a dozen adult patients diagnosed with coprophagia over the past 20 years and found that the behavior is associated with a wide range of neuropsychiatric disorders, particularly neurodegenerative dementias. The findings are published in the Journal of Neurology.

New Partnership to Study Link Between Olfaction and Neurodegenerative Disease

Deterioration in a person’s ability to smell can sometimes be an early sign of neurodegenerative diseases such as Parkinson’s or Alzheimer’s. Now, researchers at the Monell Center have established a collaboration with the Brain Health Registry to gain better insight into how changes in a person’s sense of smell may relate to health status and cognitive function.

Study: Regular Exercise at Any Age Might Stave Off Alzheimer’s

Research from the University of Kentucky College of Health Sciences was able to demonstrate a positive correlation between fitness and blood flow to areas of the brain where the hallmark tangles and plaques of Alzheimer’s disease pathology are usually first detected, indicating a possibility that regular exercise could stave off AD symptoms.

Researchers Examining Whether Comprehensive Lifestyle Changes Can Impact Progression of Alzheimer’s Disease

Cedars-Sinai neuroscience researchers are studying whether extensive changes in lifestyle among patients with mild cognitive impairment can slow the progression of Alzheimer’s disease. The research comes amid a sharp rise in the numbers of people affected by Alzheimer’s disease, the most common form of dementia. The disease affects more than 5 million Americans, but diagnoses are expected to triple by 2050, costing the healthcare system an estimated $1.2 trillion annually.

The Alzheimer's Drug Discovery Foundation and The Association for Frontotemporal Degeneration announce The Treat FTD Fund, a $10 million investment to develop effective treatments for frontotemporal degeneration, a complex form of dementia that affects more than 50,000 people in the United States. The fund was created thanks to a commitment of $5 million from The Lauder Foundation and Ronald S. Lauder, and $5 million from the Samuel I. Newhouse Foundation.

Brain Imaging Links Alzheimer’s Decline to Tau Protein

Using a new imaging agent that binds to tau protein and makes it visible in positron emission tomography (PET) scans, scientists at Washington University School of Medicine in St. Louis have shown that measures of tau are better markers of the cognitive decline characteristic of Alzheimer’s than measures of amyloid beta seen in PET scans.

Common Antacid Linked to Accelerated Vascular Aging

Chronic use of some drugs for heartburn and gastroesophageal reflux (GERD) speeds up the aging of blood vessels, according to a published paper in Circulation Research (early online), an American Heart Association journal. This accelerated aging in humans could lead to increased cardiovascular disease, vascular dementia and renal failure.

Genetic Variations that Boost PKC Enzyme Contribute to Alzheimer’s Disease

newton_PKC_AD_variant.jpg

In Alzheimer’s disease, plaques of amyloid beta protein accumulate in the brain, damaging connections between neurons. Now, researchers at University of California San Diego School of Medicine and Harvard Medical School have found that the enzyme Protein Kinase C (PKC) alpha is necessary for amyloid beta to damage neuronal connections. They also identified genetic variations that enhance PKC alpha activity in patients with Alzheimer’s disease.
