A protein from the Borna disease virus rescues mitochondria and keeps stressed neurons viable, suggesting a new neuroprotective strategy.
MRI in mice could help explain disconnections in neural circuitry that precede amyloid plaques.
The severity of ALS correlates with how badly mutations destabilize superoxide dismutase 1, and promote its aggregation, according to a new study.
By beaming red light at a blood sample and measuring the scattered photons, scientists claim to identify people with Alzheimer’s disease.
Two trials suggest that a fixed combination of a cough medicine and a cardiac arrhythmia medicine might treat agitation and quiet emotional outbursts in people with Alzheimer’s.
People with moderate to severe Alzheimer’s have higher levels of orexin, a neuropeptide that keeps people awake, a study reports. The findings solidify links between orexin and sleep disturbances associated with the disease.
Aβ oligomers rapidly seed tau pathology in macaques, potentially providing a model for drug testing that better reflects human pathology.Aβ oligomers rapidly seed tau pathology in macaques, potentially providing a model for drug testing that better reflects human pathology.
Using a rarely implemented in vitro fertilization procedure, a woman whose family carries a presenilin mutation delivered twins who are virtually assured of escaping early onset Alzheimer’s disease.
Not all viruses kill their prey. In fact, at least one virus that invades neurons preserves its hosts by turning off cell death pathways. Now, researchers have used this trick to stave off neurodegeneration. In Nature Communications, French researchers report that a protein from the Borna disease virus protects mitochondria and rescues neurons in a mouse model of Parkinson’s. A fragment of the protein may work as a neuroprotective agent.
At the 139th meeting of the American Neurological Association, held October 12-14 in Baltimore, scientists explained some of the newest therapies, preventative techniques, and diagnostic tests that may help control Alzheimer’s disease. An in vitro fertilization procedure has helped one woman who has early-onset Alzheimer’s in her family conceive twins with normal copies of the presenilin 1 gene. On the therapeutics front, a drug that is FDA-approved to quell uncontrollable laughing and crying reduced emotional outbursts and calmed patients with Alzheimer’s and other dementias. In addition, scientists reported that Raman spectroscopy of the blood might distinguish people with AD from healthy peers and people with other dementias.
Given that drugs that looked promising in Alzheimer mice have failed in human trials, is it time to find a better model? A new report claims that middle-aged macaque monkeys rapidly developed key features of AD, including neurofibrillary tangles, when Aβ oligomers were injected into their brains. Some researchers think these primates might provide a clearer picture of how AD therapeutics will perform in people.
