User:Mr. Ibrahem/Transient global amnesia

Transient global amnesia (TGA) is a condition of sudden onset, were people are unable to form new memories. There may also be problems remembering recent past memories. No other signs of neurological problems are generally present and the condition lasts less than 24 hours.

The cause is unclear. Risk factors include a history of migraines and a family history. Triggers may include emotional or physical stress. Diagnosis is based on symptoms after ruling out other potential causes including: stroke, epilepsy, encephalitis, migraine, and concussion.

Treatment generally involves observation with repeated examinations until the ability to form new memories returns. Though the period of memory loss generally does not return. Outcomes are good; however, up to 5% of people may have another episode within a year.

Transient global amnesia affects about 7 per 100,000 people a year. It most commonly occurs in those over the age of 50. Males and females are affected with similar frequency. It was first clearly described in the 1950s.
