AI+AR Equals Altoida ’s Alzheimer’s Detection Solution

Altoida is combining artificial intelligence, machine learning, and augmented reality to help detect Alzheimer’s disease. The Houston, TX-based company has struck a chord with venture capitalists, raising $6.3 million in a series A round. The financing was led by M Ventures, the corporate venture capital arm of the science and technology company Merck KGaA, Darmstadt, Germany, with participation from Grey Sky Venture Partners, VI Partners AG, Alpana Ventures, and FYRFLY Venture Partners. The new capital will be used to further expand Altoida's presence worldwide with an immediate focus on commercialization activities in the U.S. and Europe markets. Altoida said it offers healthcare professionals a novel way to objectively assess cognitive and everyday functions, in the most ecologically valid way, prior to the onset of symptoms. The firm’s digital biomarkers harness advances in technology to detect brain changes early in the disease process, helping to accelerate early diagnosis for better clinical outcomes. Using an iPad or a Tablet accelerometer, gyroscope and touch screen sensors, Altoida is able to detect "micro-errors" as both a prognostic and diagnostic digital biomarker. The result is that medical professionals are able to detect Alzheimer's disease in patients 62+ years old between six and ten years prior to the onset of symptoms - and before irreversible damage occurs. The company’s product analyzes vis...

Intra-gastrointestinal amyloid-β1-42 oligomers perturb enteric function and induce Alzheimer's disease pathology. J Physiol. 2020 Jul 02;: Authors: Sun Y, Sommerville NR, Liu JYH, Ngan MP, Poon D, Ponomarev ED, Lu Z, Kung JSC, Rudd JA Abstract KEY POINTS: Alzheimer's disease (AD) patients and transgenic mice have beta-amyloid (Aβ) aggregation in the gastrointestinal (GI) tract. It is possible that Aβ from the periphery contributes to the load of Aβ in the brain, as Aβ has prion-like properties. The present investigations demonstrate that Aβ injected into the GI tract of I...

Pathogenic tau triggers tauopathy, which serves as a focal point for many other neurodegenerative diseases. Nanogold polyethylene glycol(Au ‐PEG) alters tau as a nanochaperon and lowers protopathic tau burden while also acting as kinetic stabilizer preventing tau oligomerization. Au‐PEG inhibits amyloidosis in human AD serum by remodeling tau‐like pro‐dementia factors. Editing tau function by Au‐PEG brings optimism to managing Alzheimer's dementia. AbstractTauopathy is a complex disorder associated at the junction of several other pathologies. Intrinsically disordered tau protein remains therapeutically challengi...

We report a new class of natural-product-inspired covalent inhibitors of telomerase that target the catalytic active site. Age-Related Epigenetic Changes that Suppress Mitochondrial Function https://www.fightaging.org/archives/2020/03/age-related-epigenetic-changes-that-suppress-mitochondrial-function/ Today's open access research reports on two specific epigenetic changes observed in old individuals that act to reduce mitochondrial function. This joins an existing list of genes for which expression changes are known to impact mitochondrial function with age. A herd of hundreds of mitochondria are found ...

Alzheimer's disease is characterized by the presence of protein aggregates in the brain. These are misfolded and altered versions of proteins that can act as seeds for solid deposits to form and spread in the brain. These deposits are surrounded by a halo of toxic biochemistry that harms and eventually kills neurons. Amyloid-β aggregates are present in the early stages of the condition, while tau aggregates cause much greater harm and cell death in the later stages. Alzheimer's disease is also an inflammatory condition, however, in which chronic inflammation and altered behavior of the central nervous system im...

In Reply The Letter to the Editor by Montero-Odasso and colleagues addresses noncognitive manifestations of Alzheimer disease (AD). Their letter discusses a recent article from the Mayo Clinic. Using positron emission tomography biomarkers of amyloidosis (A) and tauopathy (T), the Mayo study examined the age- and sex-specific prevalence of 3 biologically defined entities: amyloidosis (A+) regardless of tau status, A+T −, and A+T+. We compared the age and sex specific prevalence of these 3 biomarker-defined entities with 3 clinical syndromes commonly associated with AD: clinically defined probable AD using the McKhann...

In the progression of Alzheimer ’s disease (AD), subtle cognitive difficulties may develop prior to or alongside the early phases of amyloid accumulation, according to astudy published Monday inNeurology. The findings challenge the hypothesis that amyloidosis (the buildup of amyloid proteins) comes first in the Alzheimer ’s disease process.Kelsey R. Thomas, Ph.D., of the VA San Diego Healthcare System and colleagues analyzed data from 747 people aged 55 to 90 without dementia who participated in theAlzheimer ’s Disease Neuroimaging Initiative. The participants received PET imaging to determine amyloid lev...

We examined, in a community-based population (N = 777, aged 50–95) (1) what variables were associated with each of the CSF (N) markers, and (2) whether the variables associated with each marker differed by increased brain amyloid. CSF T-tau was measured with an automated electrochemiluminescence Elecsys immunoassay; NfL and Ng were measured with in-house enzyme-linked immunosorbent assays.ResultsMultiple variables were differentially associated with CSF NfL and T-tau levels, but not Ng. Most associations were attenuated after adjustment for age and sex. T-tau had the strongest association with cognition in ...

We examined these clinical groups in relation to the bivariate distribution of amyloid and tau PET values. Individuals were grouped into amyloid (A)/tau (T) quadrants based on previously established abnormality cut points of s tandardized uptake value ratio 1.48 (A) and 1.33 (T). Individual participants largely fell into one of three amyloid/tau quadrants: low amyloid and low tau (A−T−), high amyloid and low tau (A+T−), or high amyloid and high tau (A+T+). Seventy per cent of cognitively unimpaired and 74% of FTD pa rticipants fell into the A−T− quadrant. Participants with mild cognitive impai...
