Early signs of alzheimer’s
This new method that scientists have developed aims to identify Alzheimer’s disease in its early stages. According to a study, a group of scientists is working on a “dual-mode brain-sensing device” that can quickly and accurately identify Alzheimer’s disease (AD).

Hanli Liu, a professor of bioengineering at the University of Texas in Arlington, will head the project “Digital Biomarkers for Alzheimer’s Disease with Compact Dual-Mode Brain Sensing.” According to him, “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.”
We are able to find digital neurophysiological indicators thanks to the development that is proposed here. They can be used to screen for early-stage Alzheimer’s disease and to reliably identify Alzheimer’s in each patient after we cross-validate them,” he continued. is capable of being completed.The device records data from both dry/wireless electroencephalograms (EEGs) and near-infrared (NIR) spectroscopy, according to the article.

In electroencephalography (EEG), electrical activity in the brain represents dynamic neural activity, whereas in spectroscopy, NIR light is absorbed and released by the human cortex. According to the paper, this versatile tool may measure a wide range of brain-health characteristics, including cerebral metabolism, cerebral blood volume, cerebral oxygenation, brain oscillation power, functional connectivity, and neurovascular coupling.

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.
