Alzheimer’s Disease

As I had mentioned in the introductory section of this presentation Alzheimer’s is one of the most common diseases that fall under the banner of dementia.

There are two proteins called Amyloid and Tau that are found in the brains of people with Alzheimer’s. The amyloid protein forms something called plaques around the brain cells, whereas the tau protein gets tangled brain cells. Thought that these interactions affect the ability the nerve cells to work properly. This has been seen in a reduced ability different nerve cells to communicate with one another and the form off reduced level of chemical messengers, which are called neurotransmitters, between brain cells.A key neurotransmitter called acetylcholine is only present in Low concentrations in the brains Alzheimer’s patients. When medicines such as donepezil are given to the patients increase levels of the acetylcholine neurotransmitter in the brain, which then leads to improved brain function and consequently alleviates symptoms.

Although they are able to control the symptoms of Alzheimer’s cure for the disease.The different parts of the brain have different functions, the symptoms dementia vary depending on what part of the brain has been damaged.Investigations have shown that the hippocampus, which is responsible for capturing memories, is often affected by the disease. This is why memory issues can be one of the earliest symptoms Alzheimer’s patients.Rarer forms of Alzheimer’s disease begin with language of vision rather memory problems.
