Herein, we review current knowledge on the epidemiology, pathophysiology, clinical diagnosis, and prognosis of TGA. There is no medication required to treat TGA.Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of anterograde amnesia (the inability to encode new memories), accompanied by repetitive questioning, sometimes with a retrograde component, lasting up to 24 hours, without compromise of other neurologic functions. If TGA felt to be the most likely cause then patients are usually counseled and provided with some reassurance. Patients may be referred to a neurologist for an opinion. TGA is usually a benign condition, and no specific treatment is required. Routine blood work, including electrolytes, white blood cell count, hemoglobin (to assess for anemia) as well as some blood work such as, a toxicology (drug) screen, and imaging of the brain by CT scan, MRI, and electroencephalogram (EEG) to assess for seizures may all be used to assess for or exclude other causes of memory disturbance. No abnormality of physical examination and labs (see below).Clinical presentation: Sudden loss of memory, in a fully conscious individual, that is transient and recovers fully.Neurological examination: A brief assessment of memory plus evaluation of speech, vision, muscle tone, strength and reflexes, gait, posture, and balance.Vital signs: Blood pressure, heart rate, temperature, respirations.Potential exposure to infectious organisms (e.g.Psychiatric history (depression, anxiety, bipolar).Prior history of seizures, migraine, stroke, and dementia.Unusual emotional or physical stress/strain.They continue to be amnestic for the event, or at best have an only sketchy memory of the event When the symptoms begin to clear up, the patient’s memory is usually restored completely (sometimes within minutes).Usually, there are no other symptoms, such as weakness, speech or vision problems.Is unable to recall the episode of memory loss once recovered.Asks the same questions repeatedly because she or he does not remember the answer.newborn grandchild), if their association with the patient is within the period of retrograde memory loss Personal identity and recognition of familiar objects or people are often retained, although the patient may not recognize recently acquired objects or people (e.g.The memory loss is often described as “confusion”, as it is not apparent to witnesses why the individual suddenly cannot recall specific events.For some, the memory disturbance might be a few days, while others may have memory loss for months or even years The extent is variable from patient to patient. Sudden onset of memory loss for previous events (retrograde memory loss).Many patients are anxious or agitated and may repeatedly ask questions concerning ongoing events.
