Science without borders is needed to solve the mystery of Alzheimer’s disease


Alzheimer’s Disease & Related Disorders

Unpublished research at Symposium developed to fast-track prevention, together with treatment as well as cure for the unbearable disease affecting 1 in 3 seniors has been shared by 16 of the top Alzheimer’s scientists of the world.

Dean of the Keck School of Medicine of USC, Rohit Varma had welcomed the elite group to the 4th annual Zilkha symposium on Alzheimer Disease & Related Disorders. Varma had stated that he is delighted to host this conference that tends to bring together the best and the brightest physician-scientists from across the globe for studying new, basic, translational as well as clinical efforts in the field of Alzheimer’s and related neurodegenerative disorders.

He expects that with their wisdom, insight together with hard work they would put an end to the menace of this disease. Rudolph Tanzi of Harvard University, David Holtzman – Washington University, John Trojanowski and Virginia Man-Yee Lee - University of Pennsylvania, Kaj Blennow – University of Gothenburg in Sweden, Roger Nitsche – University of Zurich, Christer Betsholtz – Uppsala Universitet in Sweden and Ronald Petersen – Mayo Clinic college of Medicine are said to be some of the researchers that have joined Keck School of Medicine scientists Berislav Zlokovic and Paul Aisen in presenting their new discoveries.

Symptoms – 15 Years After Sticky Amyloid Proteins – Dull the Brain

According to Aisen, director of the USC Alzheimer’s Therapeutic Research Institute that leads eight clinical trials on the disease, states that the symptoms of Alzheimer’s tends to appear around 15 years after sticky amyloid proteins seem to dull the brain.

Quoting data from the on-going Alzheimer’s Disease Neuroimaging Initiative study, Aisen had informed that around 80% of the participants having amyloid deposits in their brain but no symptoms of Alzheimer’s have developed symptoms of the disease within the next nine years.

Relatively only about 20% of the people devoid of amyloid deposits had later on developed related symptoms. He further added that he was of the opinion that they needed to carry this study further till they would feel that almost everyone with elevated amyloid would progress to symptomatic AD.

 Moreover it seemed reasonable to anticipate that they tend to start the trashy of anti-amyloid, 15 years prior to the expected onset of symptoms, they would be capable of preventing the development of clinical Alzheimer’s disease. In order to the trace the development of the disease over a period of time, Aisen has been enrolling healthy individuals having no symptoms of Alzheimer’s in clinical studies.


Biomarkers in Blood

In comprehending the disease and its progress would assist in the development of a `liquid bipsy’ blood test which would bring about an insight to the doctors wherein individuals could be at high risk for Alzheimer’s. In future, once the doctors tend to identify that a patient has early build-up of amyloid, they will be capable of prescribing a drug that could destroy the same.

 Thereafter, individuals could take a drug like a BACE- inhibitor in order to prevent amyloid build-up according to Aisen. Aisen had also added that doctors will ultimately be in a position of identifying people likely to develop Alzheimer’s through biomarkers found in blood draws, which will simplify preventive treatment. Director of the Zilkha Neurogenetic Institute, Zlokovic had challenged the amyloid hypothesis of Aisen stating that amyloid is not ground zero for neurodegeneration.

Zlokovic had commented that he is a bit worried if they consider Alzheimer’s is exclusively amyloid-derived neurodegeneration. He would state that this is a very complex, multifactorial disease which is motivated by genetic, vascular and environmental factors that all can effect disease inception and progression. He further added that disease inception may or may not include amyloid at all.

Healthy Brain – Healthy Blood Vessels

He explained that according to latest studies, issues in brain circulation like subtle damage to the smallest brain vessels, capillaries, loss of cerebrovascular integrity as well as blood flow changes taking place early could be vital to disease progression and lead to amyloid and tau pathology.

Zlokovic has been performing pioneering research on how leaks in the vascular system of the brain, the blood-brain barrier, tend to cause a flow of issues, inclusive of amyloid build-up. Zlokovic had mentioned that health epidemic of the 21st century is age-linked small vessel disease of the brain. Small vessel disease is said to contribute to around 45% of all dementias all over the world including Alzheimer’s.

Zlokovic recently had installed as the Mary Hayley and Selim Zilkha Chair in Alzhemier’s Disease Research further commented that a healthy brain needs healthy blood vessels. The blood-brain barrier averts the entry into the brain of blood deprived toxic products, pathogens and cells. Over 70 USC researchers over a range of disciplines have been inspecting the health, societal as well as political effects and its implications of Alzheimer’s.

 Zlokovic had informed that they would be looking forward to hosting this symposium again the next year and that it is critical for top experts of Alzheimer’s to come together and share their unpublished discoveries, concept and state-of-the art approaches in order that scientific barriers are eliminated and all tend to work together in arresting and reversing this devastating disease.
