Transcript:

As populations have aged, dementia has soared to become the fifth leading cause of death worldwide. Alzheimer's disease, a form of dementia, accounts for most of these cases. Tens of billions of dollars have been spent on Alzheimer's research over the past several decades, but still there is no cure. All attempts to halt the progression of the disease have failed. Now many major drug companies have pulled out of research altogether. So why is Alzheimer's disease still such a medical mystery? One of the signs of Alzheimer's in the brain is damage of connections and the loss of large numbers of neurons over time. It affects the hippocampus and its connected structures, making it harder to form new memories or learn new information. As damage spreads through the brain, the cortex becomes thinner, and more memories are lost, although emotional responses can often remain. As the brain shrinks further, it slowly alters personality and behavior and eventually the ability to live and function independently.

* Click on the correct answer

Alzheimer’s disease mainly occurs among the old people, who often have difficulties in forming new memories or learning new information. Although there is no cure for this disease, tens of billions of dollars have been spent on its research, giving scientists and physicians hope to cure it in the near future. Scientists haven’t found any evidence that Alzheimer’s disease can directly lead to death, but they suggest that patients suffering from it should live with their family, as they may lose the ability to live independently. The progression of Alzheimer’s disease can be halted, but it damages patients’ brains anyway. There is still no cure for Alzheimer’s disease, a form of dementia accounting for many deaths worldwide. It damages the neurons in the brain, and slowly changes people’s personality and behavior, and finally the ability to live on their own. Alzheimer’s disease can influence a person’s memories and emotional responses, by damaging the connection between the body and the brain. Around one fifth patients who suffer Alzheimer’s disease eventually die, even with the aid of major drug companies.

Option 3: "There is still no cure for Alzheimer’s disease, a form of dementia accounting for many deaths worldwide. It damages the neurons in the brain, and slowly changes people’s personality and behavior, and finally the ability to live on their own."

Explanation: This option accurately summarizes the main points of the text. It highlights the lack of a cure for Alzheimer's, its status as a leading cause of death, and the damage it causes to neurons, personality, and the ability to live independently, all of which are key themes in the original text.

Option 1: "Alzheimer’s disease mainly occurs among the old people, who often have difficulties in forming new memories or learning new information. Although there is no cure for this disease, tens of billions of dollars have been spent on its research, giving scientists and physicians hope to cure it in the near future."

Explanation: This option incorrectly implies that there is hope for a cure, which contradicts the text stating that all attempts to halt the disease have failed. Additionally, it oversimplifies the impact of Alzheimer's by focusing only on memory difficulties without mentioning the broader effects on personality and behavior.

Option 2: "Scientists haven’t found any evidence that Alzheimer’s disease can directly lead to death, but they suggest that patients suffering from it should live with their family, as they may lose the ability to live independently. The progression of Alzheimer’s disease can be halted, but it damages patients’ brains anyway."

Explanation: This option is incorrect because it states that there is no evidence linking Alzheimer's to death, which contradicts the text that identifies it as the fifth leading cause of death. It also inaccurately claims that the progression can be halted, which is not supported by the text.

Option 4: "Alzheimer’s disease can influence a person’s memories and emotional responses, by damaging the connection between the body and the brain. Around one fifth patients who suffer Alzheimer’s disease eventually die, even with the aid of major drug companies."

Explanation: This option is incorrect as it misrepresents the relationship between Alzheimer's and emotional responses, suggesting a direct connection that is not supported by the text. Furthermore, it inaccurately states that one fifth of patients die from the disease, which is not mentioned in the text, and implies that drug companies are successfully aiding patients, which contradicts the text's assertion that major companies have pulled out of research.
