AI blood test from IBM could help with early Alzheimer’s detection

Alzheimer's

Conversely, in the eyes of 39 people with Alzheimer's disease, that web was less dense and even sparse in places. "We also found a reduction in the thickness of (of a specific layer of the retina) in Alzheimer's patients compared to controls and those with mild cognitive impairment".

He also claimed that the learning model could drastically slow down the progression of Alzheimer's disease.

Diagnosing the condition at present involves a brain scan, a spinal tap to analyse cerebrospinal fluid or, more frequently, a doctor assessing symptoms.

"There is a strong effort in the research community to develop a less invasive test, such as a blood test that can yield information about Alzheimer's disease risk, " he said.

Prof Fekrat and lead author Prof Dilraj Grewal, who are based in the same lab, expect their work will one day have a positive impact on patients' lives.

Now the only ways to definitively diagnose Alzheimer's are through expensive brain scans or by taking a fluid sample from the patient's spinal cord.

New internet challenge #trashtag inspires people to pick up trash
But a new viral challenge has sent people on a cleanliness drive around the world, with results that are quite fantastic . Then take another photo of it after you've collected the garbage and post both in social media under #trashtag .

"It's not possible for current techniques like a brain scan or lumbar puncture to screen the number of patients with this disease".

"Cognitively normal, healthy individuals do not have these changes in their retina", said Dr. Sharon Fekrat, the study's lead researcher Dr. Sharon Fekrat.

She added: "We need to detect the disease earlier and introduce treatments earlier". This latest research is the largest study to date and adds to the current literature as scientists strive to find a quick, noninvasive, and low-priced way to detect Alzheimer's at the earliest stages. The retina's job is to convert light into neural signals which it sends to the brain to be processed into understandable images.

Researchers obtained data from study participants by using optical coherence tomography angiography, a non-invasive scan that can pick up on blood flow in the retina.

Upwards of 5.5 million Americans are estimated to possibly have the brain wasting disease, according to NIH, and these numbers will continue to increase in years to come if no cure is found, projections suggest an impending and staggering global impact of dementia and neurodegenerative diseases.
