G45.4: Transient global amnesia

Transient global amnesia is a sudden, temporary episode of memory loss that can't be attributed to a common neurological condition, such as epilepsy or stroke. During an episode, the individual's ability to recall recent events or new information is severely impaired, causing disorientation. However, the person retains personal identity and knowledge of well-known past events. The condition typically resolves on its own within 24 hours without any treatment. The exact cause behind transient global amnesia is unclear, but it's often triggered by strenuous physical activity, emotional stress, minor head injuries, or sudden temperature changes. Notably, patients experiencing this disorder do not show any other neurological deficits, and it does not lead to lasting cognitive damage. Rarely, a person may have more than one episode of transient global amnesia in their lifetime.
