What does anamnesis mean?
Anamnesis is the act of calling past events to mind, most familiarly as the medical term for a patient's history — the account of symptoms, prior illnesses, and family background that a clinician gathers before making a diagnosis. The word derives from the Greek anamnēsis, meaning 'remembrance' or 'calling to mind', and it carries deep roots in Western thought: Plato held that genuine learning is not the acquisition of new information but the recollection of truths the soul already possesses, a doctrine he called anamnesis. The same root gives us amnesia, its near-opposite, meaning loss of memory. Today anamnesis appears mainly in technical registers — medical records, psychoanalytic literature, theological discussions of liturgical remembrance — where it lends precision and a certain scholarly gravity. For general readers, it is best understood as a refined synonym for recollection, one that signals careful, systematic remembering rather than casual reminiscence.
nounThe act or process of recalling to mind past experiences, especially a patient's account of their medical history; in philosophy, the Platonic doctrine of knowledge as recollection of what the soul knew before birth.
- A patient's case history as recounted to a physician or taken during a clinical interview.
- Recollection or remembrance generally, especially in philosophical or theological contexts (e.g. Plato's theory of knowledge as recollection, or liturgical commemoration).
"The physician took a careful anamnesis before ordering any tests."
"A thorough anamnesis revealed that her symptoms had begun weeks earlier than she had first reported."
"In Plato's Meno, Socrates demonstrates anamnesis by drawing geometric knowledge out of an untutored slave boy."
The plural follows standard Latinized -es ending for Greek nouns ending in -is.
"The clinic compared anamneses across several generations of the family."
Plato believed all learning is actually remembering — and the word for that idea, anamnesis, is still used by doctors every day when they ask about your medical history.

Etymology of anamnesis
Anamnesis comes from the Greek anamnēsis, formed from ana- ('back') plus mnēsis ('remembrance'), rooted in the verb mimnēskesthai, 'to recall'. It entered English in the early modern period, initially through learned and theological writing, and was later adopted into medicine for the systematic taking of a patient's history. Its Greek root mnē- also underlies amnesia, mnemonic, and amnesty, making these true cognates.
