Diaschisis

/daɪˈæskɪsɪs/ noun

Definition

A neurological condition where damage to one part of the brain affects distant, connected brain regions, disrupting their normal function.

Etymology

From Greek 'dia-' (through) + 'schisis' (splitting or separation), describing how brain injury 'splits' function across distant regions.

Kelly Says

Diaschisis explains why a stroke in one brain area can affect seemingly unrelated abilities—the brain is a web of connections, and damaging one node sends ripples everywhere.
