Also known as: Digitale Demenz (Spitzer)
German: Digitale Demenz
Digital dementia is the title and central thesis of Manfred Spitzer’s book Digitale Demenz (2012): that heavy use of digital media, especially by children and adolescents, impairs learning, memory and attention; it is a thesis in a public and scientific debate, not a medical diagnosis.

In one sentence
Digital dementia: Manfred Spitzer’s thesis (2012) that heavy digital media use impairs learning and memory — a contested thesis, not a diagnosis.
Example
A text that writes “digital dementia shows that …” presents the thesis as a finding. A neutral wording is: “Manfred Spitzer argues in Digitale Demenz (2012) that …; reviews of the research literature have disputed the claim.”
The thesis
Manfred Spitzer, a psychiatrist and brain researcher, argues in Digitale Demenz: Wie wir uns und unsere Kinder um den Verstand bringen (Droemer, 2012) that digital media take mental work away from their users and that heavy use, especially in childhood and adolescence, harms the development of learning, memory and attention. The book became a bestseller in Germany and was discussed controversially.
The criticism
Markus Appel and Constanze Schreiner (2014) examined central claims of the debate on the effects of internet use against the meta-analytic research literature and concluded that the evidence does not support the broad negative effects claimed. Reviewers of the book acknowledged its accessible presentation of brain research while questioning how far its conclusions follow from the studies cited.
Evidence status
“Digital dementia” is not a diagnosis in medical classification systems. It names a thesis. Research on specific effects of media use — for example on attention, sleep or learning in particular settings — exists and is mixed; it is discussed under those specific questions, not under the label of the thesis. This entry does not judge the thesis or its criticism.
How it applies
- Attribution: Texts that use the term should attribute it to Spitzer and mark it as a thesis.
- No advice on health: The entry gives no recommendations on media use for children or adults.

How to read this pool
Entries, context cards and transitional topics
The art of thinking explains ways of thinking — where a method comes from, what it asks of you and how it was adapted later. You meet four kinds of content here, each with its own job:
- Glossary entry
- Defines one concept or method of thinking: its origin, an example and how it relates to neighboring ideas. “X vs. Y” sections set two methods side by side.
- Context card of the art of thinking
- A short, self-contained answer to one question about a way of thinking — its lineage, its steps, its limits. These cards are listed on The art of thinking only.
- Transitional topicBridges both pools
- A context card that bridges both pools: it shows how a way of thinking was adapted into documentation, analysis or quality practice. It sits with the reference context cards and is marked as transitional wherever it appears.
- Reference entry or context card
- Belongs to the Glossary & Norms Space on regulation, norms and engineering. Entries here link to one only where a method is also an established tool of documentation or quality work, such as the five whys or a user’s mental model.
