Neurodegenerative Decline Following Mild Traumatic Brain Injury: A Case Report

A 71-year-old woman with an initially undiagnosed mild traumatic brain injury (mTBI) from a fall was retrospectively diagnosed 17 months later and subsequently found to have probable Lewy body dementia, with rapid neurological decline leading to death 33 months post-injury. The case highlights concerns about delayed mTBI diagnosis, inadequate provider training, medication overuse without proper diagnosis, and the need for multidisciplinary evaluation and equitable access to specialized concussion care, particularly in elderly populations.
