A new questionnaire developed by researchers in the U.S. could help with the early diagnosis of mild cognitive impairment and Alzheimer's disease. The Everyday Cognition questionnaire or ECog is made up of 39 questions and is filled out by someone who knows the affected person well. The questionnaire measures the same things as established tests and its results were found to agree with medical diagnoses. It was able to differentiate between people with no cognitive problems, those with mild cognitive impairment and those with Alzheimer's and its results did not appear to be strongly influenced by education as is the case with some other tests.
