Development of cognitive instruments for use in clinical trials of antidementia drugs:Alzheimer's Disease Assessment Scale (ADAS).
What is Alzheimer's Disease Cooperative Study?
The Alzheimer's Disease Cooperative Study (ADCS) cognitive assessment procedure was created to investigate the validity and reliability of cognitive assessment tools that could be useful additions to the Alzheimer's Disease Assessment Scale (ADAS) or other short batteries used in antidementia medication studies. Patients with mild to moderate AD and elderly individuals with normal cognitive function underwent a battery of five tests at least three times over the course of a year as part of an overall ADCS protocol to create new instruments for use in clinical trials of treatments for Alzheimer's disease (AD). The main result of this inquiry was the discovery of certain prospective additions to the current ADAS that broaden the scope of the cognitive domains and symptom severity levels addressed.

Answer: Carbon-14
Explanation:
Carbon dating the procedure which is used for the substances which is used to date the substances less than 40,000.
This method is based on an unstable isotope of carbon that living animals and plants incorporate inside it.
When the organisms are alive the ratio of stable isotope inside the organism is same to the ratio that is found in the atmosphere.
As the organism dies the carbon 14 gets converted into nitrogen 14. By measuring both the ratios, the relative age can be determined.
