Taiwanese scientists have developed an artificial intelligence (AI) application that utilizes electroencephalography (EEG) signals to spot mild cognitive impairments that often occur before dementia is diagnosed.
The Ministry of Science and Technology on Wednesday said that the diagnosis system is used for the accurate and rapid screening of mild cognitive impairments and ensuing Alzheimer’s disease-induced dementia
The tool — which has a 92 percent accuracy — was developed by National Taiwan University of Science and Technology and HippoScreen Neurotech Corp in a ministry-funded program, the ministry told a news conference in Taipei, adding that it funded the research.

Lead researcher Liu Yi-hung (劉益宏), a professor of mechanical engineering at the university and founder of HippoScreen, said that the EEG signal patterns of people with mild cognitive impairments are less complex than those of healthy people.
The decreased complexity of EEG signals corresponds with increasing communication difficulties, he said.
Researchers developed algorithms to decipher, classify and interpret EEG signals with regard to signs of impending dementia, he said.
The researchers used EEG data from 80 study participants, he said, adding that the results were published in multiple peer-reviewed academic journals, including the International Journal of Fuzzy Systems, he said.
The technology — which would be available to health professionals as a cloud-based service — would help doctors diagnose mild cognitive impairments within 40 seconds of uploading an EEG reading to the server, he said.
The researchers are working on a follow-up program to improve the system, with the goal to collect EEG readings from 500 participants before the end of June next year, he said.
The research team’s partners in the next phase of testing include National Taiwan University Hospital, Tri-Service General Hospital, Taipei Veterans General Hospital and Chang Gung Memorial Hospital, he said.
The Food and Drug Administration and its US counterpart have approved the technology, which would become available to medical professionals in the second half of next year, he said.
Tsai Chia-fen (蔡佳芬), a psychiatrist at Taipei Veterans General Hospital, said that 15 to 20 percent of people with mild cognitive impairments later developed Alzheimer’s-induced dementia.
The new tool would help assess dementia risks in older people at risk of the disease, she added.
The system’s underlying technologies have the potential for further development and application in treating other conditions, including depression and drug addiction, said Chen Chih-ken (陳志根), a psychiatrist at Chang Gung Memorial Hospital’s Keelung branch.
A strong continental cold air mass and abundant moisture bringing snow to mountains 3,000m and higher over the past few days are a reminder that more than 60 years ago Taiwan had an outdoor ski resort that gradually disappeared in part due to climate change. On Oct. 24, 2021, the National Development Council posted a series of photographs on Facebook recounting the days when Taiwan had a ski resort on Hehuanshan (合歡山) in Nantou County. More than 60 years ago, when developing a branch of the Central Cross-Island Highway, the government discovered that Hehuanshan, with an elevation of more than 3,100m,
Death row inmate Huang Lin-kai (黃麟凱), who was convicted for the double murder of his former girlfriend and her mother, is to be executed at the Taipei Detention Center tonight, the Ministry of Justice announced. Huang, who was a military conscript at the time, was convicted for the rape and murder of his ex-girlfriend, surnamed Wang (王), and the murder of her mother, after breaking into their home on Oct. 1, 2013. Prosecutors cited anger over the breakup and a dispute about money as the motives behind the double homicide. This is the first time that Minister of Justice Cheng Ming-chien (鄭銘謙) has
TRANSPORT CONVENIENCE: The new ticket gates would accept a variety of mobile payment methods, and buses would be installed with QR code readers for ease of use New ticketing gates for the Taipei metro system are expected to begin service in October, allowing users to swipe with cellphones and select credit cards partnered with Taipei Rapid Transit Corp (TRTC), the company said on Tuesday. TRTC said its gates in use are experiencing difficulty due to their age, as they were first installed in 2007. Maintenance is increasingly expensive and challenging as the manufacturing of components is halted or becoming harder to find, the company said. Currently, the gates only accept EasyCard, iPass and electronic icash tickets, or one-time-use tickets purchased at kiosks, the company said. Since 2023, the company said it
Ferry operators are planning to provide a total of 1,429 journeys between Taiwan proper and its offshore islands to meet increased travel demand during the upcoming Lunar New Year holiday, the Maritime and Port Bureau said yesterday. The available number of ferry journeys on eight routes from Saturday next week to Feb. 2 is expected to meet a maximum transport capacity of 289,414 passengers, the bureau said in a news release. Meanwhile, a total of 396 journeys on the "small three links," which are direct ferries connecting Taiwan's Kinmen and Lienchiang counties with China's Fujian Province, are also being planned to accommodate
