Implanting a chip into the brain can help people with Parkinson’s disease control symptoms associated with the disease and improve their quality of life, a doctor said yesterday after tracking a patient with such a treatment for a decade.
The man, surnamed Tseng (曾), was in his prime when he was diagnosed with Parkinson’s disease two decades ago. Even after taking drugs for nearly a decade, his condition continued to deteriorate and he decided to accept the implant to control his illness.
Lin Hsin-jung, superintendent at China Medical University Beigang Hospital, said the body of a person with Parkinson’s disease is like a vehicle which has brakes that are too strong and hampers free movement.
Implanting the chip into the patient’s brain will stimulate a safe and effective electric current that will mitigate the “brakes phenomenon,” Lin said.
Tseng’s symptoms began to show when he was only 37. In the beginning, his limbs would shake involuntarily. He was advised to take drugs regularly, but after more than eight years, he had to increase dosage and the side effects disturbed his sleep. He developed hallucinations and vomited sometimes. His weight dropped to 50kg.
After the deep brain stimulation surgery, he has cut his drugs, limb shaking, body rigidness and other symptoms. He could even work and tour around with his wife and he is now happier than before.
Parkinson’s disease is a degenerative disorder of the central nervous system, and the disease is more common among the elderly.
Taiwan has 40,000 people with Parkinson’s disease.
Most are given drugs in the initial stage, but there are commonly side effects after taking the drugs for many years, Lin said.
He said that about 600 Parkinson’s disease patients have received deep brain stimulation in the country.
Although the medical equipment to conduct such surgery is expensive, he said the quality of life of patients has greatly improved and they cut the cost of hiring caretakers.
“In this light, the surgery is economically more efficient than simply giving patients medicines,” Lin said.

The Chinese Nationalist Party (KMT) caucus yesterday said it opposes the introduction of migrant workers from India until a mechanism is in place to prevent workers from absconding. Minister of Labor Hung Sun-han (洪申翰) on Thursday told the Legislative Yuan that the first group of migrant workers from India could be introduced as early as this year, as part of a government program. The caucus’ opposition to the policy is based on the assessment that “the risk is too high,” KMT caucus secretary-general Lin Pei-hsiang (林沛祥) said. Taiwan has a serious and long-standing problem of migrant workers absconding from their contracts, indicating that
UNREASONABLE SURVEILLANCE: A camera targeted on an road by a neighbor captured a man’s habitual unsignaled turn into home, netting him dozens of tickets The Taichung High Administrative Court has canceled all 45 tickets given to a man for failing to use a turn signal while driving, as it considered long-term surveillance of his privacy more problematic than the traffic violations. The man, surnamed Tseng (曾), lives in Changhua County and was reported 45 times within a month for failing to signal while driving when he turned into the alley where his residence is. The reports were filed by his neighbor, who set up security cameras that constantly monitored not only the alley but also the door and yard of Tseng’s house. The surveillance occurred from July
TRADE-OFF: Beijing seeks to trade a bowl of tempura for a Chinese delicacy, an official said, while another said its promises were attempts to interfere in the polls The government must carefully consider the national security implications of building a bridge connecting Kinmen County and Xiamen, China, the Public Construction Commission (PCC) said yesterday. PCC Commissioner Derek Chen (陳金德), who is also a minister without portfolio, made the remarks in a meeting of the legislature’s Transportation Committee, after Democratic Progressive Party Legislator Hsu Fu-kuei (徐富癸) asked about China’s proposal of new infrastructure projects to further connect Kinmen and Lienchiang (Matsu) counties with Xiamen. China unveiled the bridge plan, along with nine other policies for Taiwan, on Sunday, the last day of Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun’s (鄭麗文) visit
