G45.4

Clinical Causes: Migraine-related phenomena Physical or emotional stress Sudden immersion in cold or hot water Vigorous physical activity Minor head trauma Sudden changes in blood pressure Certain medical procedures or surgeries Unknown factors in some cases

Key Symptoms: Sudden inability to remember recent events or conversations Difficulty recalling newly acquired information Preservation of personal identity and distant memories No loss of consciousness during episodes Possible mild confusion or disorientation Sudden onset of symptoms that resolve within hours Repeating questions or statements Typically no neurological deficits post-episode

Diagnosis Path: Diagnosing Transient Global Amnesia involves careful assessment to distinguish it from other neurological conditions. Healthcare providers will review medical history, conduct physical and neurological examinations, and use imaging tests such as MRI or CT scans to rule out stroke, seizure, or other serious issues. Additional assessments can include blood tests to identify underlying conditions. Since TGA episodes resolve quickly, the diagnosis relies on characteristic features, including the sudden onset of amnesia and rapid recovery.

Treatment Protocols: There is no specific treatment for Transient Global Amnesia. Management usually focuses on supportive care during episodes and monitoring for any underlying or related health issues. Patients are often advised to rest and avoid driving or operating machinery immediately after an episode. Follow-up evaluations may be recommended to explore potential triggers or underlying health concerns. Most individuals recover fully without long-term consequences, but consultation with a healthcare professional is advisable for proper assessment and reassurance.
