Alzheimer’s is a type of dementia that affects memory, thinking and behavior. It accounts for 60-80% of dementia cases. People with younger-onset Alzheimer’s can be in the early, middle or late stage of the disease.
A team of researchers is developing a “dual-mode brain-sensing device” that detects Alzheimer’s disease (AD) quickly and effectively, a new report has said.
According to UTA (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”.
This device records data from near-infrared (NIR) spectroscopy, as well as from dry/wireless electroencephalograms (EEG), according to the report. This multifunctional device will be able to measure a variety of brain-health parameters, such as cerebral metabolism, cerebral blood volume, cerebral oxygenation, brain oscillation powers and functional connectivity and neurovascular coupling.
“The proposed development enables us to identify digital neurophysiological biomarkers. After we cross-validate them, they can be used for accurate detection of Alzheimer’s in each patient as well as for screening for the early phase of AD,” Hanli Liu added in her statement.
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.
In spectroscopy, NIR light is absorbed and emitted by the human cortex, while in electroencephalography, electrical activity in the brain reflects dynamic neural activity. This device records data from near-infrared (NIR) spectroscopy, as well as from dry/wireless electroencephalograms (EEG), according to the report.
