This New Years’ Day, I Learned About Transient Global Amnesia in a Very Personal Way


This New Years’ Day was a very odd day for my father in legislation, Jim. Not that he remembers a lot of it.

It was a day that Jim woke early. He went to shave, as standard. Then he discovered he’d misplaced his reminiscence.  


For hours he would repeatedly ask these round him if he’d already shaved, confused by stubble-free pores and skin and a whole lack of recollection. He could not keep in mind the place he spent Christmas, both. Or final Thanksgiving. His current travels via Australia had vanished. So too any reminiscence of the present US president.

The turning level got here when his daughter – my spouse – stepped into the room to examine on him.

“Is … is she pregnant?” Jim mumbled out loud, baffled.

Due in March, his daughter struggled to grasp the query – any earlier state of drained bewilderment now greater than trivial.

“Are you joking?” she requested. “If that’s the case, it is not humorous, Dad.”

“Why did not you inform me you have been pregnant?” Jim accused with an insistence that was out of character.

All types of ideas run via your thoughts when this can be a member of your loved ones. Is it a stroke? Dementia? You seize any medical data you will have at hand to reassure your self issues are going to be okay.

There was no signal of slurring or muscle weak point. Fingers have been sturdy, freed from shaking. However months had spontaneously evaporated from Jim’s thoughts, and certainly that wasn’t good.


As terrifying because the expertise was for his household, Jim’s prognosis turned out to be a constructive one. We joke about it now in hindsight, all checks exhibiting zero abnormalities. MRI, CT, bloods … all clear. Mockingly he has little reminiscence of the occasion itself. It is ‘simply a kind of issues’. A medical curiosity. A blip.

We perceive that Jim had an episode of transient world amnesia, a benign situation as mysterious as it’s unusual. Fewer than 10 in each 100,000 folks expertise it every year, and we nonetheless do not know what causes it.

I sought recommendation from Amee Baird, a scientific neuropsychologist from Macquarie College in Sydney who has come throughout the odd case up to now.

“Though there have been lots of of reported instances of transient world amnesia within the medical literature, the trigger remains to be unknown, and it’s considered some of the mysterious of all of the neurological circumstances,” says Baird.

“Varied triggers have been reported, together with strenuous bodily exercise, emotionally arousing or nerve-racking occasions, and a sudden change in physique temperature.”


Migraines look like a danger issue, as are numerous cardiovascular points.

Baird does not take into account herself an professional within the phenomenon, however has acquired a number of sufferers who’ve skilled this spontaneous, brief time period lack of reminiscence. Like me, she finds such quirks of the mind fascinating.

Baird provides that intercourse may also be a set off, an element she explored whereas researching her upcoming e-book by New South Publishing, Intercourse on the Mind.

“In a single research was the set off in a 3rd of instances,” Baird says.

Which occasions – if any of them – preceded my father in legislation’s expertise, I am all of a sudden reluctant to dig into. Even my scientific curiosity has its limits. 

Fortuitously there isn’t a suggestion that Jim’s non permanent brush with amnesia is a symptom of in poor health well being. We will anticipate him to attend many extra Christmases sooner or later, and nearly actually keep in mind all of them for some time to come back. As scary as it’s for many who witness the occasion, there are not any recognized long run results.

Given the person has been a distinguished historian and story teller himself, clear reminiscence performs an intrinsic a part of his id. It is given his household pause to be grateful, and aware of the impression extra extreme losses of long run reminiscence within the type of dementia many others face.


Essentially the most extreme residual impact appears to be a slight issue in focussing, to not point out a son in legislation who insists on too many questions on the expertise.

I ask Baird if she has any ideas on what TGA may inform us about neurology generally.

“That we nonetheless have much more to find out about reminiscence,” she says.

“Additionally, the rising proof that emotional and psychological elements can play a task in triggering TGA in lots of instances demonstrates the intimate hyperlink between emotion and reminiscence.”

If the statistics are something to go by, this can be a as soon as in a lifetime expertise for Jim. All of these recollections have returned – Christmas, Thanksgiving, and my spouse’s being pregnant.

Oh, and sure. He is aware of who the president is once more.
