Mice fed junk food for nine months showed signs of developing the abnormal brain tangles strongly associated with Alzheimer's disease, a Swedish researcher said on Friday.

“On examining the brains of these mice, we found a chemical change not unlike that found in the Alzheimer brain,” Susanne Akterin, a researcher at the Karolinska Institutet's Alzheimer's Disease Research Center, who led the study, said in a statement.

“We now suspect that a high intake of fat and cholesterol (胆固醇) in combination with genetic factors ... can adversely affect several brain substances, which can be a contributory factor in the development of Alzheimer’s.”

Alzheimer’s disease is incurable and is the most common form of dementia (痴呆) among older people. It affects the regions of the brain involving thought, memory and language.

While the most advanced drugs have focused on removing clumps of βamyloid protein(β淀粉蛋白) that forms plaques in the brain, researchers are also now looking at therapies to address the toxic tangles caused by an abnormal build-up of the protein tau (T形蛋白).

In her research, Akterin focused on a gene variant (基因突变) called apoE4, found in 15 to 20 percent of people and which is a known risk factor for Alzheimer’s. The gene is involved in the transport of cholesterol.

She studied mice genetically engineered to imitate the effect of the variant gene in humans, and which were fed a diet rich in fat, sugar and cholesterol for nine months -- meals representing the nutritional content of fast food.

These mice showed chemical changes in their brains, indicating an abnormal build-up of the protein tau as well as signs that cholesterol in food reduced levels of another protein called Arc involved in memory storage, Akterin said.

“All in all, the results give some indication of how Alzheimer's can be prevented, but more research in this field needs to be done before proper advice can be passed on to the general public,” she said.

61. What did Susanne Akterin find in her research?

A. Signs of developing the abnormal brain disorders.

B. The abnormal brain disorders because of junk food.

C. Akterin’s disease linked with junk food.

D. The same chemical change in the Alzheimer brain.

62. What is Susanne Akterin’s idea about Alzheimer’s disease?

A. She thinks it’s caused by fat and cholesterol (胆固醇) with genetic factors.

B. She doesn’t believe that it’s caused by fat and cholesterol (胆固醇) with genetic factors.

C. She doubts whether it’s caused by fat and cholesterol (胆固醇) with genetic factors.

D. She believes junk food causes mice to be abnormal.

63. Which is NOT the sign of dementia among older people?

A. Often forgetting things B. Often repeating the same words.

C. Often being weak D. Unable to understand other people.

64. Which of the following is true according to the passage?

A. It’s easy to cure Alzheimer’s disease.

B. There’s no way to cure Alzheimer’s disease.

C. Akterin has found Alzheimer’s disease.

D. Akterin removedβamyloid protein (β淀粉蛋白).

65. What does Akterin’s experiment tell us?

A. Alzheimer’s disease can be avoided.

B. Alzheimer’s disease is incurable.

C. Alzheimer’s disease can be cured.

D. Mice are the same as humans.
