abstract = {Memories are our reservoir of knowledge and thus, are
crucial for guiding decisions and defining our self. The
physical correlate of a memory in the brain is termed an
engram and since decades helps researchers to elucidate the
intricate nature of our imprinted experiences and knowledge.
Given the importance that memories have for our lives, their
impairment can present a tremendous burden. In this review
we aim to discuss engram malfunctioning across diseases,
covering dementia-associated pathologies, epilepsy, chronic
pain and psychiatric disorders. Current neuroscientific
tools allow to witness the emergence and fate of engram
cells and enable their manipulation. We further suggest that
specific mechanisms of mnemonic malfunction can be derived
from engram cell readouts. While depicting the way diseases
act on the mnemonic component - specifically, on the
cellular engram - we emphasize a differentiation between
forms of amnesia and hypermnesia. Finally, we highlight
commonalities and distinctions of engram impairments on the
cellular level across diseases independent of their
pathogenic origins and discuss prospective therapeutic
measures.},
