A 19-year-old in China was diagnosed(诊断) with Alzheimer's disease(阿尔茨海默症) recently. It has made him the 1 person in the world with the condition.
Doctors at Capital Medical University's Xuanwu Hospital in Beijing said the patient's brain showed early signs of this illness. After excluding(排除) all other 2 of his disease, they diagnosed the teen with early Alzheimer's disease.
The teen's memory decline(衰减) 3 about two years ago. He had trouble in 4 events from the day before. And he was not able to finish homework. Gradually, he even could not remember 5 he had eaten or not. As 6 result, he had to drop out of high school.
The patient has no family with a history of Alzheimer's disease. And he doesn't have any head illness that could explain 7 memory difficulties.
According to recent studies, the chance of getting Alzheimer's disease increases with age. But about five 8 six per cent of people with Alzheimer's disease develop early signs of the illness before the age of 65. So this case challenges the traditional opinion of the illness and its 9 with aging. It also shows the need for more study in younger people.
"This special case was 10 published in the Journal of Alzheimer's Disease. Studying the mysteries of young people with Alzheimer's disease may become one of the most challenging scientific questions of the future," a scientist said.
