Researchers at IIT Delhi are developing algorithms that detect the source of epileptic seizures
Researchers at the Indian Institute of Technology – Delhi have developed a novel algorithm that can locate the epileptogenic zone based on a patient’s EEG data.
In drug-resistant epilepsy, neurosurgeons must first determine the exact origin and extent of structural abnormalities in a patient’s brain before they can operate on them surgically. Evaluation of such anomalies typically involves invasive procedures that can take anywhere from 2 to 8 hours.
The team developed a brain source localization framework for focal epilepsy detection that they describe as “time-efficient and patient-friendly”.
According to a press release, the array processing algorithms, based on novel head harmonics, can provide coordinates “within minutes”.
Researchers validated the algorithms using clinical EEG data to localize epileptogenic zones in a Study published in Nature Scientific Reports.
University of Hong Kong engineers develop coin-sized biosensor platform
A research team from Hong Kong University’s Faculty of Engineering has developed a tiny biosensor system for personalized health monitoring.
Dubbed the PERfECT (Personalised Electronic Reader for Electrochemical Transistors), it’s thought to be the world’s smallest system of its kind that can be integrated into a smartwatch or used as a patch to continuously monitor parameters such as blood glucose levels, antibody levels in the blood, and sweat.
“Our wearable system is tiny, soft and imperceptible to the wearer, and it can continuously monitor our body condition,” said Dr. Shiming Zhang, who leads the research team.
According to the researchers, the coin-sized system can read faint electrochemical signals at a data sampling rate of up to 200 kilosamples per second – a performance comparable to bulky commercial devices.
The PERfECT system can serve as a miniaturized electrochemical station for portable devices and can be used immediately in several portable systems based on low-voltage transistors.
To make this technology accessible, the HKU research team reportedly created a startup called SESIC.
ThoughtFull mental health app partners with AIA Malaysia
AIA Malaysia integrates online mental health support from digital mental health app ThoughtFull into its business insurance offering.
Through this partnership, ThoughtFull’s digital mental health services will become part of AIA Malaysia’s corporate solutions portfolio.
The connection comes as a new report by Mercer Marsh Benefits found that one in three insurers in Asia does not offer coverage for mental illness as part of their insurance plans.
“Physical health and illness have traditionally been largely covered by insurance, but the same is not true of mental health and illness in this region. This coverage gap, and the consequent cost of accessing mental health and wellbeing services, has been a barrier to access for many,” said Joan Low, CEO and Founder of ThoughtFull.
