A 26-year-old woman has been diagnosed with Wilson’s disease, which could lead to brain and liver dysfunction, and even death if left untreated, a Hsinchu doctor said on Tuesday last week.
Wilson’s disease is a rare genetic disorder in which copper builds up in the body, said Lee Cheng-hsuan (李承軒), a neurologist at National Taiwan University Hospital’s Hsinchu branch.
It has a prevalence of about one per 30,000 individuals worldwide, but the rate is higher in Asia, Lee said.

The patient, who requested anonymity, experienced shaking hands and difficulty walking to the extent that she had to lean on walls to walk, Lee added.
Clinical examinations showed that she had neurological problems, such as muscle stiffness and slow motor function, as well as brown discoloration in the eyes (Kayser-Fleischer rings), which are common signs and symptoms of Wilson’s disease, he said.
Blood and urine tests, and brain and liver screenings confirmed that she had the disease, he added.
Other common symptoms include dystonic postures, muscle rigidity, difficulty swallowing, difficulty speaking and poor articulation (dysarthria), lack of coordination, and changes in personality and behavior, Lee said.
As copper accumulates in the body, particularly in the brain and the liver, people with Wilson’s disease could develop cirrhosis at a young age and exhibit neurological symptoms in their 20s or 30s, he said.
It is a recessive genetic disorder, meaning parents of the individual with the abnormal gene do not usually exhibit symptoms, Lee said.
The woman’s 23-year-old brother has also been diagnosed with the disease, he said.
Unlike most other genetic disorders, Wilson’s disease can be treated by medication, which helps remove the excess copper from the body, Lee said, adding that people with the disease should follow a low-copper diet to prevent the condition from worsening.
People with Wilson’s disease need to take medication throughout their lives, but early diagnosis and treatment would drastically improve their life quality, as the disease is progressive, and delaying treatment could result in fatal brain or liver complications, he said.
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
Quarantine awareness posters at Taiwan Taoyuan International Airport have gone viral for their use of wordplay. Issued by the airport branch of the Animal and Plant Health Inspection Agency, the posters feature sniffer dogs making a range of facial expressions, paired with advisory messages built around homophones. “We update the messages for holidays and campaign needs, periodically refreshing materials to attract people’s attention,” quarantine officials said. “The aim is to use the dogs’ appeal to draw focus to quarantine regulations.” A Japanese traveler visiting Taiwan has posted a photo on X of a poster showing a quarantine dog with a
