New findings on Alzheimer's have been released in Australia. The build up of beta-amyloid plaque is thought to be the main cause of Alzheimer's and it is also responsible for cognitive decline over the long term. The presence of plaque in the brain enables diagnosis of Alzheimer's even in people who show no immediate symptoms. This was announced by Dr Christopher Rowe, professor of nuclear medicine at Melbourme's Austin Hospital.
A patient can now know years in advance that he/she will develop Alzheimer's. Whether this is a good thing is debatable, though it does give time for a person to get their things in order. Depression could be the result of making such an emotive discovery.
Eighteen million people suffer from Alzheimer's worldwide. With the large segment of the population moving into the elderly group this is expected to reach 34 million by 2025. A new drug to fight plaque has been approved in the US. Hopefully, a medication can be found that will dissolve the plaque.
