Diagnosis and Treatment
This results in a trigger that goes off to cause destruction of nerve cell connections, or synapses, in the brain. A new drug called saracatinib is being tested in mice studies to observe whether the drug can turn off Fyn, allowing nerve transmissions to function normally again. The mice studies were effective and now, saracatinib is being tested in human clinical research studies.
This process causes a collapse of the system normally responsible for transporting nutrients to the brain cells. Scientists are currently working on new vaccines and other types of drugs that may prevent tau from forming these abnormal tangles. Another new experimental treatment for AD involves finding a way to reduce the inflammation process. New drugs cannot be made available to the public until they have gone through all phases of clinical trials to ensure they can halt, or slow down, the process of AD, and that they are safe for long-term human use.
Researchers anticipate the need for over 4, new participants to get involved by volunteering for clinical trials. People with mild cognitive impairment MCI and those who are healthy enough to participate as controls are needed.

However, they often cause increased confusion, so their use should be limited. A group of medications called cholinesterase inhibitors have shown some effectiveness in slowing the progression of the condition in some people.
These medications help prevent the breakdown of acetylcholine, a neurotransmitter responsible for memory.
Preventing Alzheimer’s Disease
Cholinesterase inhibitor medications that are available in New Zealand include donepezil, rivastigmine and galantamine. More recently, another drug - memantine - has become available in New Zealand.
Memantine works in a different way to the cholinesterase inhibitors, aiming to prevent the entry of an excess amount of calcium into brain cells. Higher than normal levels of calcium in the brain cells causes damage to them and also prevents them from receiving signals from other brain cells. Research continues into the development of other medications for the treatment of Alzheimer's disease. Medications being investigated include those that prevent the build-up of amyloid deposits in the brain, as well as looking at the use of some anti-inflammatory and hormone medications.
Research also continues into the use of alternative therapies such as anti-oxidants like Vitamin E, curcumin, selenium and some herbal extracts ginko balboas in particular. There are no proven ways to prevent the development of Alzheimer's disease. However, there is epidemiological evidence to suggest that leading a healthy lifestyle can reduce the risk of Alzheimer's disease.
Regular physical activity and exercise may have a general protective effect on brain health and may slow progression of Alzheimer's disease. Although there are no specific dietary specifications for Alzheimer's, a Mediterranean-style diet ie: plant foods such as vegetables, fruits, beans, whole grains, nuts, olives and olive oil, along with some cheeses, yoghurt, fish, poultry and eggs may reduce the risk of Alzheimer's disease, and has the added benefit of lowering cardiovascular disease and type 2 diabetes risk.

Alzheimer’s Disease: Current Treatments and Potential New Agents
These theories dominated the field and led some to believe we were on the verge of effective treatments — through preventing or removing these abnormal proteins. But had the theories been correct we would likely have had at least one or two positive clinical trials. In retrospect, the multi-decade amyloid fixation looks like a mistake that could have been avoided. Versions of this observation date back to at least the s.
It was always possible that the classic plaques and tangles first seen by Alois Alzheimer , and now known to be made of abnormal proteins, were epiphenomena of aging and not the cause of the disease. Epiphenomena are characteristics that are associated with the disease but are not its cause. This now includes but is not limited to: infection , disordered inflammation , abnormal diabetes-like metabolism and numerous environmental toxins.
And the past few years have seen more evidence for viral , bacterial and fungal infections.
These viral and bacterial hypotheses were portrayed as eureka moments. But this begs the question: How did powerful tools of epidemiology miss associations with things like cold sores and gum disease?

Some authorities have been trying to make such arguments for some time. Either of these would be bad news, since we would need to develop multiple effective treatments, possibly in combination.
