The sudden onset of visual hallucinations following a change in habits might be indicative of an alcohol addiction, a Hualien physician said, after treating a man in his 50s diagnosed with the condition.
The man, surnamed Huang (黃), went to Hualien Tzu Chi Hospital after experiencing hallucinations while recovering from the flu, psychiatrist Shen Yu-chih (沈裕智) said.
After speaking with Huang and running various tests, doctors determined that Huang had experienced the effects of alcohol withdrawal, which had manifested as hallucinations when he stopped drinking while taking flu medication.
Huang often used rice wine in his cooking and over time had started drinking wine with his meals, eventually leading to an addiction, Shen said.
Huang’s family were concerned that he had a mental illness when he began having hallucinations, but mental illnesses generally do not develop so rapidly, Shen said, adding that most people with mental conditions who hallucinate have auditory hallucinations, rather than experiencing changes of vision.
Alcohol acts as a depressant in the central nervous system and might slow the brain’s communication with the rest of the body, Shen said, adding that if people who habitually drink alcohol suddenly stop, their nervous system might experience a rebound effect.
“Basically, there are withdrawal symptoms. The whole brain becomes excited with activity and there is the possibility of hallucinations,” Shen said.
Modern treatments for addiction can include psychotherapy and medication, he said.
Hualien Tzu Chi Hospital uses three types of medication for alcoholism, including one that neutralizes the effects of alcohol so that it has as much as an effect on the patient as water, Shen said.
The second type makes the patient feel nauseated at the scent of alcohol, while the third neutralizes alcohol’s effects on the central ner-vous system, he added.
However, medication can only be part of an overall treatment program for addiction patients, Shen said.
People with addictions tend to lack something in their lives that they are trying to make up for, he said, adding that successful treatment helps people fill the holes in their lives with something constructive and beneficial.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said.

Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
