If you believe the theme of the World Dementia Council (WDC) meeting in London this week, dementia is “in a new era,” where it will be possible to prevent, diagnose and treat neurodegenerative disease. That is not the case for most people living with dementia today, but the approval of the first disease-modifying drugs and the imminent arrival of new blood-based biomarkers is “a big moment,” Lenny Shallcross, executive director of WDC told the meeting on Mar. 20.
A new study has uncovered a potential link between RNA regulation and the development of neurodegenerative diseases, such as Parkinson’s disease and dementia. This work, conducted by researchers at the University of Nottingham, used a combination of microscopy and machine learning techniques to examine the role of N6-methyladenosine modification of RNA (m6A) in the human brain.
A new blood test developed by Durin Technologies Inc. and Rowan-Virtua School of Osteopathic Medicine detected the presence of Alzheimer’s disease pathology in nearly all asymptomatic patients who went on to developed cognitive impairment or dementia, a study in the Journal of Alzheimer’s Disease found. The test uses eight autoantibody biomarkers to identify patients with the disease at pre-symptomatic, prodromal and mild-moderate stages of disease.
A shortage of efficacy compared to placebo in a phase II study of treating cognitive impairment has put Aptinyx Inc. on the defensive. The company’s oral, small-molecule NMDA receptor modulator, NYX-458, was being studied in 99 patients with mild cognitive impairment or mild dementia associated with Parkinson’s disease or Lewy body dementia. Based on the results, Aptinyx has decided to stop the therapy’s development, along with closing its phase IIb study of another oral, small molecule, NYX-783, for treating post-traumatic stress disorder.
Neurodiagnostics LLC (dba Synaps Dx) and Linus Health Inc. reported significant advances for their dementia diagnostics Feb. 16, adding to the liquid biopsies and radiologic studies currently used and potentially expanding access to beneficial treatments for Alzheimer’s disease (AD) and other dementias.
The shunt towards, or away from, cognitive decline may happen decades before such decline becomes clinically evident. And known risk factors explain very little of that decline. That is the conclusion reached by researchers from the Ohio State University, who published their results in the Feb. 8, 2023, issue of PLOS ONE.
In their analysis, the team looked at both the absolute level of cognitive function in about 7,000 participants of the U.S. Health and Retirement Study at age 54, and at the decline in cognitive function from age 54 to 85. The study participants that were analyzed were born between 1931 and 1941. The results were reminiscent of the adage that the way to make a silk purse out a sow’s ear is to start with a silk sow.
The sigma 1 receptor is widely distributed in the nervous system and its function has been implicated in a number of neurological disorders including dementia, Alzheimer’s disease (AD) and other neurodegenerative diseases. In a recent publication, researchers from the University of Nebraska detailed the discovery of novel sigma 1 receptor modulators.
At the recent Clinic Trials on Alzheimer’s Disease (CTAD) conference in San Francisco, Regenlife SAS presented the design for its Light4life study examining the therapeutic efficacy of the RGn600 device. This trial on more than 100 subjects will evaluate the cognitive impacts of new photobiomodulation technology.
Mdoloris Medical Systems SAS and Pprs SAS reported a joint venture to launch ANI Guardian, a connected medical device that continuously and non-invasively tracks pain levels and well-being in a range of non-verbal or cognitively impaired people.
Two phase III failures with Roche Holding AG subsidiary Genentech Inc.’s gantenerumab in staving off mild cognitive impairment tied to Alzheimer’s disease (AD) revealed the level of amyloid-beta removal was lower than the company expected. The protein amyloid beta accumulates in the brains of AD patients and its removal is suspected to be an eventual boon to AD patients. But there are still plenty of doubts. Top-line results from Genentech’s phase III Graduate I and II studies show gantenerumab, a fully human monoclonal IgG1 antibody, missed the primary endpoints of slowing clinical decline in those with mild cognitive impairment due to AD and mild AD dementia.
