A collaborative research project by Taichung Veterans General Hospital and Taipei Veterans General Hospital has found that if measures could be introduced to prevent or cure cerebrovascular disease, it could help prevent or slow the progression of Alzheimer’s disease.
One percent of people over the age of 65 have Alzheimer’s, Lee Wei-ju (李威儒), a doctor from Taichung Veterans General Hospital’s Dementia and Alzheimer Treatment Center, said on Thursday.
With every year after 65, the risk of developing Alzheimer’s increases 2 to 5 percent, Lee said.

Alzheimer’s is most often seen as a kind of dementia and there is still no cure for it, he said.
However, cerebrovascular disease is a key factor in causing Alzheimer’s, Lee added.
People with coronary artery disease, atrial fibrillation, hypertension, diabetes and high cholesterol, as well as those who smoke, are obese or do not exercise enough, can develop cerebrovascular disease, Lee said.
Research in the US and Europe showed that due to the control of such factors, the number of Alzheimer’s cases has decreased.
On average, the mental health of people with Alzheimer’s regresses by two to three points on the Mini-Mental State Examination (MMSE) every year, Lee said.
The neurological centers at both hospitals tracked 330 people with Alzheimer’s for three years. They had an average age of 80, had been diagnosed with Alzheimer’s four to five years earlier, had averaged 18.7 points on the MMSE at the time of diagnosis and had been diagnosed from 2012 to 2016, he said.
The research found that people with three or more high-risk factors lost six points on average on the MMSE during the research, while those with less than three regressed less than two points on the MMSE, Lee said.
People who have apolipoprotein E4 would also see an increased rate of mental health regression, Lee added.
The study showed that control and treatment of factors leading to cerebrovascular disease is the most important method for slowing the progression of Alzheimer’s, Lee said, adding that it is to be published by the American Geriatrics Society.
The military has spotted two Chinese warships operating in waters near Penghu County in the Taiwan Strait and sent its own naval and air forces to monitor the vessels, the Ministry of National Defense (MND) said. Beijing sends warships and warplanes into the waters and skies around Taiwan on an almost daily basis, drawing condemnation from Taipei. While the ministry offers daily updates on the locations of Chinese military aircraft, it only rarely gives details of where Chinese warships are operating, generally only when it detects aircraft carriers, as happened last week. A Chinese destroyer and a frigate entered waters to the southwest
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
The next minimum wage hike is expected to exceed NT$30,000, President William Lai (賴清德) said yesterday during an award ceremony honoring “model workers,” including migrant workers, at the Presidential Office ahead of Workers’ Day today. Lai said he wished to thank the awardees on behalf of the nation and extend his most sincere respect for their hard work, on which Taiwan’s prosperity has been built. Lai specifically thanked 10 migrant workers selected for the award, saying that although they left their home countries to further their own goals, their efforts have benefited Taiwan as well. The nation’s industrial sector and small businesses lay
