Medicine has made great progress in the 2oth century but still not all diseases can be cured. Two such diseases are Alzheimer’s disease and Parkinson’s disease. In this essay I will discuss the similarities and differences of these two diseases and describe some of the symptoms. First, there are only two similarities between the diseases. Both of them are caused by genetics. This means that some people are more likely to get the diseases than other people are. Scientists think that the disease can be passed on from parent to child.
Furthermore, research seems to show that both diseases affect people who are older more than they do people who are younger. It seems that people over 60 are more likely to get the diseases. Another similarity between them is that there is no cure or successful treatment of the diseases. Although there is much research, scientists have not been able to find a cure. Research is ongoing, however, so there is still hope that a cure may be found. There are more differences between the diseases than there are similarities.
Although they both affect the brain, the symptoms are different. A big difference is that Parkinson’s disease is caused by a loss of neurons in the brain which means patients can’t control their body movements. The cells which affect body movement are damaged. Patients also have trouble with balance and coordination. However, with Alzheimer’s disease, the symptoms are forgetting how to do simple tasks like remembering people’s names or understanding simple things.
In conclusion, both diseases are serious diseases that cannot be cured. Although they are similar in some ways, they both have different symptoms. People over 60 are most at risk of getting these diseases. In my opinion, I think that organizations should continue to research both diseases to find a cure. If enough money is donated so that much research could be done, maybe a cure could be found before the end of the 21st century. If so, it would be welcome news to many people who now suffer from these diseases. 345 Words.
