Has my close one's memory changed?

Alzheimer's disease, as well as other forms of dementia, are characterized, among other things, by a memory performance that deteriorates over time. The timely detection of changes is essential for early diagnosis.

What can you do if a person close to you is no longer remembering things as well as they did two years ago? What if they no longer know what day or month it is? This scientifically validated online questionnaire is the first important step toward a timely diagnosis of dementia and contributes to early detection. Use the questionnaire to assess the person’s memory if you’ve known them for at least two years. Once you’ve checked the boxes for the seven questions, you’ll receive a clear overall assessment. If a certain threshold is reached, we’ll provide a recommendation for next steps.

Scientific Evidence:

Unlike many other questionnaires, this one uses a proven scientific method. The basis is the so-called IQCODE Questionnaire (The Informant Questionnaire on Cognitive Decline in the Elderly – übersetzt: “Fragebogen für Bezugspersonen zum kognitiven Abbau bei älteren Menschen”). Der IQCODE ist ein bewährter und weltweit verbreiteter Fragebogen, mit dem sich der Abbau der Gedächtnisleistung gegenüber einem früheren Funktionsniveau mit Hilfe einer Bezugsperson abschätzen lässt (Jorm et al. 1989, Jorm et al. 2004).

The IQCODE questionnaire is recommended in dementia diagnostic guidelines (The National Institute for Health and Care Excellence – NICE).

The informant questionnaire on our website is based on the German short form of the IQCODE with 7 questions, which is from Ehrensperger et al. validated in a 2009 study.
