Alzheimer’s disease affects more than 30 million people around the world and there is no cure. For decades, research on the neurological condition has been focused on proteins known as amyloid and tau, which build up in the brains of people and prevent neurons from functioning properly. But treatments that focus on flushing those proteins out of the brain have so far proved underwhelming. A growing number of scientists, however, have a radical alternative theory. What if a virus is to blame? What if infections are the triggers that cause the build-up of amyloid and tau in the first place?

 A small study of only 22 patients found that their risk of developing Alzheimer’s symptoms was cut in half after taking an experimental drug targeting amyloid plaques, a hallmark of the disease, for an average of eight years.

“It is a very novel discovery showing that simply inhaling an inert gas can have such a profound neuroprotective effect,” said senior and co-corresponding author Oleg Butovsky, PhD and director of the lab where the research took place at Brigham and Women’s.

“One of the main limitations in the field of Alzheimer’s disease research and treatment is that it is extremely difficult to design medications that can pass the blood-brain barrier—but Xenon gas does. We look forward to seeing this novel approach tested in humans.”

Could key changes in intra-network connectivity revealed on brain magnetic resonance imaging (MRI) scans indicate the development of Alzheimer’s disease or Parkinson’s disease in patients with mild cognitive impairment (MCI)?

For a new study, recently published in Academic Radiology, researchers reviewed cognitive function assessments and resting-state functional MRI (fMRI) data for 33 patients who had MCI prior to Alzheimer’s disease (AD), 55 patients who had MCI prior to developing Parkinson’s disease (PD) and 34 healthy controls. The cognitive function assessments with the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were performed within one hour prior to fMRI, according to the study.

a new study in mice brings us one step closer to understanding what triggers the disease. The researchers have uncovered a specific enzyme that may be behind one of the key features of Alzheimer’s.
