Perelman School of Medicine at the University of Pennsylvania researchers have discovered a mechanism involving the neurotransmitter dopamine that switches fruit fly behavior from being active during the day (diurnal) to nocturnal… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Changes In Flies Parallel Sundown Syndrome Which May Be Due To High Dopamine Levels A drug prescribed for Alzheimer’s disease does not ease clinically significant agitation in patients, according to a new study conducted by researchers from the U.K., U.S. and Norway. This is the first randomized controlled trial designed to assess the effectiveness of the drug (generic name memantine) for significant agitation in Alzheimer’s patients… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Memantine Improves Some Alzheimer’s Symptoms But Has No Effect On Agitation Teasing out the exact type or types of dementia someone suffers from is no easy task; neurodegenerative brain diseases share common pathology and often co-occur… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Range Of Diagnostic Spinal Fluid Tests Needed To Differentiate Concurrent Brain Diseases A research team led by the University of South Florida Department of Psychiatry & Behavioral Neurosciences has found that a fragment of the amyloid precursor protein (APP) – known as sAPP-α and associated with Alzheimer’s disease – appears to regulate its own production. The finding may lead to ways to prevent or treat Alzheimer’s disease by controlling the regulation of APP… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Study Finds Alzheimer’s Precursor Protein Controls Its Own Fate Alzheimer’s disease (AD) robs people’s memories and destroys lives, but despite of almost daily reports on promising new therapies, AD is still remains unchecked. The March 23 issue of the journal PLoS One reveals that a new study has discovered the mechanism that causes memory loss in AD, which could pave the way for new treatments… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Alzheimer’s And Treating Zinc Imbalance The effects of the bacterial endotoxin lipopolysaccharide (LPS) has been found to elevate amyloid beta (Aβ) peptide levels in the brain, leading to short-term deficits in learning… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Study Of Link Between Amyloid Beta Peptide Levels And Alzheimer’s Disease Researchers at the University of Copenhagen have documented a previously unknown biological mechanism in the brain’s most important line of defence: the blood-brain barrier. Scientists now know that the barrier helps maintain a delicate balance of glutamate, a vital signal compound in the brain. Glutamate is the most important activating transmitter substance in the brain… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: New Mechanism In Brain’s Barrier Tissue Mapped By Scientists A two year, EUR 675,000 grant has been awarded to Professor Erich Wanker of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and of the Excellence Cluster Neurocure. Prof. Wanker will use the grant in order to speed up the search for active agents to treat protein misfolding diseases, such as Parkinson’s and Alzheimer’s… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Alzheimer’s And Parkinsons – Searching For Therapeutic Active Agents A report in the February issue of Archives of Neurology, one of the JAMA/Archives journals states that increases in brain cortical binding of the chemical marker called [18F]FDDNP were related to increases in clinical symptoms of neurodegeneration, whilst regional baseline values of this marker seem to be linked to with future cognitive decline… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Chemical Marker May Predict Cognitive Decline Risk One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain… View full post on Alzheimer’s / Dementia News From Medical . . . → Read More: Insight Into Cell Aging Likely Following Discovery Of Extremely Long-Lived Proteins |
