No recent history of head trauma or seizures must be present No focal neurology or epileptic features must be present No loss of personal identity must be present No cognitive impairment other than amnesia must be present No alteration in consciousness must be present a population-based study concluded that an episode of TGA does not increase the risk of subsequent cerebrovascular events, seizures, or cognitive impairment (4)Īcute onset of anterograde amnesia must be present.There is no excess of cerebrovascular disease in patients with TGA There is a correlation between TGA and migraine. diagnosis may be made safely in the presence of a characteristic collateral history.remote precipitating events, with onset reported weeks prior to TGA, are considered anxiety triggered by conflict at home or work, health problems, and financial stressors (3).close precipitating events for TGA are considered emotional stress (i.e., triggered by gastric endoscopy, birth/death announcement, and difficult/exhausting workday), physical effort (i.e., gardening, house work, and sawing wood), physical exertion (including sexual activity), and water contact/temperature change (i.e., hot bath/shower and cold swim) (3).possible that it may result from different mechanisms such as venous congestion with valsalva-like activities before symptom onset, arterial thromboembolic ischaemia and vasoconstriction due to hyperventilation (1).Precipitating factors include sexual intercourse and heavy physical exercise, particularly swimming in cold water. study evidence showed a recurrence rate of 6.3% in a 10 year period.studies show a slight female predominance.Across studies, the mean age of an episode ranges from 61 to 67.3 years most commonly presents in the seventh decade of life.
attacks usually last for 1-8 h but should be less than 24 h (1)Įpidemiological data put the annual incidence of TGA between 3.4 and 10.4/100,000 (2).patient remain alert, attentive, and cognition is not impaired.does not have any focal neurological symptoms.presents classically with an abrupt onset of severe anterograde amnesia.is unable to recall the episode once they have recovered.Is neurologically intact except for absent memory Patients with this condition are often described - wrongly - as being confused. The patient is usually over 50 years old and an attack may last several hours. Transient global amnesia (TGA) is a temporary and isolated disorder of memory. thanks.Last edited 08/2020 and last reviewed 08/2020 If anyone else has similar symptoms and can help me out a bit that would be great. I'm only 21 so i'm a bit worried about it. I've looked on the internet and the thing that i feel describes my condition the most is TEA. I also can get them happening throughout the day if i am stressed. recently they have also been accompanied by retching and vomiting. I often ask the other person questions like 'where am i', 'where are we going', 'who are you ect'. Whilst with other people/ having a conversation i will usually say someting ridiculous and completley out of context 'ie -insisting i've just seen a talking cat', but i will still be talking in full/ proper sentences. When i am alone an attack is usally accompanied with a strong feeling of anxiety. I'll know i'm on the tube, but i wont have a clue where i am going and if i go through any of the stations i wont recognise any of their names. An example is getting the tube to work in the morning and having an 'attack'.
I will remeber who i am, but i wont remember any of my STM, or any recent memories i might have made. I normally have memory loss for around 5 minutes, within the first 30 minutes of waking up. I am currently going to appointments to see a neurologist to try and help me get a diagnosis. Basically i started having memory loss in April 2015, and have done pretty much every other day since.
