What is TADPOLE?
TADPOLE is a challenge to identify which people within an age group at risk of AD will start to show symptoms in the short to medium term (1-5 years). It focusses on rollover individuals in the Alzheimer's disease neuroimaging initiative (ADNI) study. The challenge is to use historical measurements from these individuals to forecast future measurements. The following scientific questions motivate the challenge:
- How predictable is progression to Alzheimer’s Disease (AD) in at-risk individuals?
- Which data, processing pipelines, and predictive models best predict future AD progression?
- Can we use such methods to improve cohort selection for clinical trials?
We invite you to participate in TADPOLE and join the international fight against dementia and AD.
Why is it important?
AD, and dementia in general, is a key challenge for 21st century healthcare. The statistics are sobering: 7% of people over 65 and 20% over 80 suffer from dementia of which AD is the most common cause; dementia has higher health and social care costs than cancer, stroke and chronic heart disease combined – projected $1T in 2018 and $2T in 2030; a treatment slowing progression by 50% would reduce annual care costs by about 10%, i.e., $100B in 2018.
No current treatments provably cure or even slow AD. Of the hundreds of clinical trials into putative treatments, often running to billions of dollars/euros, fewer than 1% have proceeded to the regulatory approval stage and none have managed to prove a disease-modifying effect. One key reason for these failures is difficulty in identifying patients at early stages of the disease where treatments are most likely to be effective.
TADPOLE challenges you to identify what data and algorithms best predict AD progression. This facilitates early identification of patients likely to be receptive to treatment, thus purifying cohorts for clinical trials, highlighting positive treatment effects, and facilitating translation of effective treatments to market.
How does it work?
TADPOLE provides a list of individuals at an age that puts them at risk of AD. A history of informative measurements (from imaging, psychology, demographics, genetics, etc.) from each individual is available to inform forecasts. Each individual has agreed to a follow-on assessment.
TADPOLE participants predict future measurements from these individuals and submit their predictions by the submission deadline: 15 November 2017.
Once future measurements are available, TADPOLE will evaluate each forecast against them, collate and compare results, publish the results, award prizes and, ultimately, write up a scientific paper co-authored with active participants that input sufficient information.
We encourage forecasts from any source: statistical, mathematical, or computational models; or simply informed guesses by human experts. The competition is open to anyone: from statisticians to neurologists; from industry or academic research; from professor to high-school student.
Join the challenge!
The challenge is open for submissions.
Consultation on the details of the challenge remains open until 15 August 2017 after which the rules will be fixed. We welcome thoughts and suggestions on all aspects of the challenge before then – please email email@example.com.
We look forward to receiving your contributions.
