Early signs of alzheimer’s
The purpose of this new technique invented by scientists is to detect early stage Alzheimer’s. A team of researchers is developing a “dual-mode brain-sensing device” that rapidly and effectively detects Alzheimer’s disease (AD), says a study.
According to the University of Texas at Arlington, Hanli Liu, a bioengineering professor, will be the principal investigator of the project “Digital Biomarkers for Alzheimer’s Disease with Compact Dual-Mode Brain Sensing.” He states, that “what we are doing in this project is developing a quick and comfortable way to measure metabolic, hemodynamic and electrophysiological (MHE) activities in the human brain.”
“The development proposed herein enables us to identify digital neurophysiological biomarkers. After we cross-validate them, they can be used to accurately detect Alzheimer’s in each patient, as well as to screen for early-stage Alzheimer’s disease,” he added. can be done for.”
As per the report, the device records data from near-infrared (NIR) spectroscopy as well as dry/wireless electroencephalogram (EEG).
Genetic predisposition definition
In spectroscopy, NIR light is absorbed and emitted by the human cortex, while in electroencephalography (EEG), electrical activity in the brain reflects dynamic neural activity. This multifunctional device is capable of measuring a variety of brain-health parameters, such as cerebral metabolism, cerebral blood volume, cerebral oxygenation, brain oscillation power, and functional connectivity and neurovascular coupling, the report states.

Here the Alzheimer’s Association estimates that 50 million people worldwide, including more than 6 million Americans, suffer from Alzheimer’s disease and other types of dementia. Of all types of dementia, Alzheimer’s disease kills more people than breast cancer and prostate cancer combined. The report states that the cost of AD and other types of dementia was estimated at $355 billion in 2021, which is expected to rise to more than $1 trillion by 2050.
According to the article, the device records information from dry/wireless electroencephalogram (EEG) and near-infrared (NIR) spectroscopy.
While the human cortex continues to absorb and emit NIR light during spectroscopy, the electrical activity in the brain during electroencephalography (EEG) represents dynamic cerebral activity.
According to this study, this multi-purpose device is capable of measuring several aspects of brain function, including cerebral metabolism, cerebral blood volume, cerebral oxygenation, brain oscillation power, functional connections and neurovascular coupling.
