A research team finds a method to predict Alzheimer's disease within two years of screening

03 Dec 2013 - At the first signs of memory loss, most people start worrying and wonder, “What if I have Alzheimer's disease?” And yet, the disease is often diagnosed late in its development and sometimes up to ten years after the first pathological changes have affected the brain. A major goal in the treatment of Alzheimer's disease has been to provide earlier diagnosis so that patients can receive treatment as early as possible. A study by Sylvie Belleville, PhD, Director of Research at the Institut universitaire de gériatrie de Montréal, an institution affiliated with Université de Montréal, has shown a way to do just that. In their study, Sylvie Belleville and her team accurately predicted (at a rate of 90%) which of their research subjects with mild cognitive impairment would receive a clinical diagnosis of Alzheimer's disease within the following two years and which subjects would not develop this disease. The study was published in Volume 38, Issue 2 of the prestigious Journal of Alzheimer's Disease. ...

Prescription of anti-Alzheimer medications to persons with mild cognitive impairment (MCI) is low in France

15 Nov 2013 - In France prescription of drugs for Alzheimer’s disease (AD) is strictly regulated. The Department of Public Health and the Memory Clinic of Nice University Hospital have explored real world prescriptions of anti-AD medications in patients with mild cognitive impairment (MCI) not AD. A national survey [1] was set up from the data of the French National Alzheimer Databank (BNA) and shows that off label prescriptions are not frequent and concern 6.1% of MCI patients (versus a quarter of MCI patients in the US [2]). French physicians seem to limit this kind of prescription to MCI patients at risk of conversion to AD: more aged, with a more important quantitative cognitive impairment and with a memory predominant form. In a context of low efficacy of the available medications against AD this study emphasizes the need to develop more preventive drugs....

New Method Predicts Time from Alzheimer’s Onset to Nursing Home, Death

A Potential New Strategy to Face Dementia

08 Oct 2013 - Alzheimer’s disease (AD) affects millions of people worldwide. As a result of an increase in life expectancy, the number of patients with dementia is expected to increase dramatically. Due to the lack of effective treatments that can slow down or reverse the progression of AD, preventive measures to lower the prevalence rate of AD by means of managing potential or actual risk factors is a reasonable clinical strategy. In this respect, identifying treatable factors which are able to promote cognitive deterioration would have important practical implications....

Novel accelerometer-based algorithm detects early signals of Alzheimer’s disease in everyday motion behavior

08 Oct 2013 - The projected substantial increase in Alzheimer’s disease due to the higher life expectancy in modern societies is one of the great future challenges of health care systems worldwide. Alzheimer’s disease leads to significant changes in the temporal structure of activities that impair everyday activities. Abnormal motion behavior and degeneration of the sleep-waking cycle are among the most severe behavioral symptoms. An early detection and even a prediction of these behaviors would allow a timely onset of interventions that aim to delay the manifestation or exacerbation of symptoms and reduce the need of institutionalized care....

Exercise May be the Best Medicine for Alzheimer’s Disease, UMD Study Shows

07 Aug 2013 - New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function in those at risk for Alzheimer’s by improving the efficiency of brain activity associated with memory. Memory loss leading to Alzheimer’s disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer’s, for which there currently is no cure. ...

Poor dental health may lead to Alzheimer’s, study suggests

01 Aug 2013 -

People with poor oral hygiene or gum disease may be at a greater risk of developing Alzheimer’s disease, a new study led by The University of Central Lancashire (UCLan) School of Medicine and Dentistry suggests.

The research, which has received international collaboration, and led by Professor Stjohn Crean and Dr Sim Singhrao from UCLan, examined brain samples donated by ten patients without dementia and ten patients suffering from dementia. The research demonstrated the presence of products from Porphyromonas gingivalis in brains from patients suffering from dementia.

This bacterium is commonly associated with chronic periodontal (gum) disease. These bacteria enter the bloodstream through daily activities such as eating, chewing, tooth brushing but especially following invasive dental treatment, and from there, potentially enter the brain on a regular basis. The researchers propose that every time they reach the brain, the bacteria may trigger immune system responses by already primed brains cells, causing them to release more chemicals that kill neurons. This could be one mechanism that leads to changes in the brain, which is typical of Alzheimer’s disease, and could be responsible for causing symptoms such as confusion and deteriorating memory.

The research benefited from donated brain samples, provided by Brains for Dementia Research, a brain donation scheme supported by Alzheimer’s Research UK and Alzheimer’s Society. Finding P. gingivalis in the brains from dementia sufferers compared to those without dementia is significant as its presence in Alzheimer’s diseased brains has not been documented previously and at the same time adds to a growing body of evidence that suggests an association between poor oral health and dementia.

These published research findings from human brain specimens are further supported by recent (as yet unpublished) research from the same group, on periodontal disease, using animal models, which has been carried out in collaboration with the University of Florida. This animal work has confirmed that P. gingivalis in the mouth finds its way to the brain once the periodontal disease becomes established.

Professor Stjohn Crean, Dean, School of Medicine & Dentistry said:

“Whereas previous studies have indicated a link between dementia and other bacteria and viruses such as the Herpes simplex virus type I, this new research indicates a possible association between gum disease and individuals who may be susceptible to developing Alzheimer’s disease, if exposed to the appropriate trigger! Research currently underway at UCLan is playing an active role in exploring this link, but it remains to be proven whether poor dental hygiene can lead to dementia in healthy people, which obviously could have significant implications for the population as a whole.  It is also likely that these bacteria could make the existing disease condition worse.”

Dr. Sim K. Singhrao, Senior Research Fellow at UCLan said: “We are working on the theory that when the brain is repeatedly exposed to bacteria and/or their debris from our gums, subsequent immune responses may lead to nerve cell death and possibly memory loss. Thus, continued visits to dental hygiene professionals throughout one’s life may be more important than currently envisaged with inferences for health outside of the mouth only. To help us prove our hypothesis we are hoping to use the Brains for Dementia Research tissue resource to examine brain tissue from people with both intact and compromised memory who have relevant dental records. The future of the research aims to discover if P. gingivalis can be used as a marker, via a simple blood test, to predict the development of Alzhiemer’s disease in at risk patients.”

Scientists Reveal Early Diagnostic Clues for Alzheimer’s Disease Using Advanced Brain Imaging Technology

03 May 2012 -

Alzheimer's disease (AD) is a major neurodegenerative disorder that affects millions of people worldwide. New and accurate techniques for early diagnosis are critical. Pravat K. Mandal, PhD, and his colleagues have developed a completely non-invasive brain imaging technique to measure specific brain chemical changes. This provides a signature of the early stages of AD from the hippocampal region of the brain. Their work is reported in the Journal of Alzheimer’s Disease.
“Alzheimer’s disease has become a silent tsunami in the aging population,” says Dr. Mandal, who is associated with the National Brain Research Center, Gurgaon, India, and Johns Hopkins University School of Medicine.  “This discovery of a diagnostic technique that requires no blood work or radiation, and that can be conducted in less than fifteen minutes, may offer hope to Alzheimer’s disease patients and their families.”

Dr. Mandal and his co-investigators studied the brains of normal controls, AD patients, and patients with mild cognitive impairment (MCI) using multi-voxel 31P magnetic resonance spectroscopy (MRS) imaging, along with an advanced analytical tool, to assess brain chemistry in the hippocampal regions.  They observed during the course of their study that the left hippocampus becomes alkaline in AD patients, which is in contrast to the normal aging process in which the brain tends to be more acidic.  

Dr. Mandal and his colleagues also identified four brain chemicals that change significantly in pre-Alzheimer and Alzheimer disease patients compared to normal subjects.  They are phosphomonoester (PME), the building block of neuronal membrane; phosphodiester (PDE), the membrane degradation product; phosphocreatine (PCr), stored energy for brain functioning; and adenosine triphosphate (-ATP), the source of brain energy.  The level of PME is significantly decreased in the left hippocampal areas of these patients, and the levels of PDE, PCr, and -ATP are increased.  

“In the left hippocampus the increase in pH to the alkaline range, along with statistically significant increases in PDE, PCr, and y-ATP and decreases in PDE, serve as a promising new biomarker for AD,” notes Dr. Mandal.  He and his colleagues plan to conduct longitudinal studies with Alzheimer and Parkinson patients with larger sample sizes to investigate specificity of their test.  “It is our hope that such clinical research, using state-of-the-art technology, may give new hope to cognitively impaired patients for an earlier and more predictable AD diagnosis.”   

These clinical studies were performed in collaboration with Dr. Manjari Tripathi, MD, DM, Department of Neurology, All India Institute of Medical Sciences, New Delhi. This study was made possible through the research funding, to Dr. Mandal, from the Department of Biotechnology, Government of India.

Anders Lönneborg, PhD, Receives 2012 Alzheimer Award

02 May 2012 -

Anders Lönneborg, PhD, has been chosen as the recipient of the 2012 Alzheimer Award presented by the Journal of Alzheimer’s Disease in recognition of his outstanding work on the detection of early Alzheimer’s disease.

“My co-authors and I are extremely pleased to have been chosen by a distinguished group of peers as the recipients of this year’s Journal of Alzheimer’s Disease award for our work on the development of ADtect®, the 96-gene expression test for detection of early Alzheimer’s disease,” said Dr. Lönneborg, Research Director, DiaGenic, Oslo, Norway.

Each year the more than 500 Associate Editors of the Journal of Alzheimer’s Disease vote to select an outstanding article published the previous year to receive this prestigious award, which is made possible by support from IOS Press and Elan Pharmaceuticals. Dr. Lönneborg will be presented with the bronze Alzheimer Medal featuring the likeness of Alois Alzheimer. The winning paper is entitled, “A Novel Blood Test for the Early Detection of Alzheimer’s Disease" (J Alzheimers Dis 23, 121-129, 2011), by A. Lönneborg et al.

The team behind the paper, led by Dr. Lönneborg, investigated the diagnostic value of a 96-gene expression array for detection of early AD. A disease classification algorithm was developed and was validated in two steps using an independent initial test set and another second test set. A similar accuracy (72%), sensitivity (72%) and specificity (71%) were achieved both in the initial analysis and in the two independent test sets. When compared with available CSF biomarker data high agreement (80%) was found.

“Although further studies are needed to confirm these findings, they suggest that the gene expression test using a convenient blood sample can aid the diagnosis of mild to moderate AD,” adds Dr. Lönneborg.

Anders Lönneborg, PhD, received his degree in molecular plant physiology from the University of Umeå, Sweden in 1986. After a postdoctoral fellowship in molecular plant biology at Michigan State University under the mentorship of Prof. Chris Somerville, and working as Research Scientist at the Norwegian University of Life Sciences and as Senior Scientist at the Norwegian Forest Research Institute, Dr. Lönneborg was acknowledged competence as professor in 1995. In 1998 he founded DiaGenic with Dr. Praveen Sharma, where he has served as Research Director since the company’s inception and CEO from 2003-2007.

DiaGenic’s focus has always been to develop blood-based tests based on gene expression to aid the diagnosis of important diseases, primarily neurodegenerative diseases like Alzheimer’s disease and Parkinson’s disease. The company aims to develop companion diagnostics and biomarkers to aid the development of novel treatments for Alzheimer’s disease.
