most common cause of transient global amnesia

Here we are going to share information on the topic “most common cause of transient global amnesia.” A sudden episode of bewilderment in an otherwise awake person is known as transient global amnesia. There is no more common neurological illness causing this disoriented state, such as epilepsy or stroke. Despite the extremely minimal chance of temporary worldwide amnesia following these occurrences, sudden immersion in hot or cold water is one frequently mentioned scenario that may cause it. physically demanding activities. Sexual activity.

A person experiencing temporary global amnesia loses the ability to form new memories, which causes the recollection of recent events to vanish. You are unable to recall how or where you got here. You might not recall anything about the current situation. If you don’t recall the answers you were just given, you can find yourself asking the same questions over and over again. When asked to recall events that occurred a day, a month, or even a year ago, you can also come up blank.

The majority of those affected by the illness are middle-aged or older. You are aware of who you are and who you know well, even if you have momentary global amnesia. Transient global amnesia episodes always gradually improve after a few hours. As you heal, you can start recalling specific incidents and situations. Although transient global amnesia is not dangerous, it can nevertheless be unsettling.

Who is affected by temporary worldwide amnesia?

Most victims of transient global amnesia are in the 50–80 age range (75 percent of cases). People under 40 are rarely affected.

Transient global amnesia may be more common in those with a history of the following medical disorders, according to certain studies:

  • Heart conditions.
  • Migraine.
  • Overweight (high cholesterol).

How frequent is temporary worldwide amnesia?

Temporary worldwide amnesia is uncommon. Approximately 5 to 10 people out of every 100,000 in the US are impacted by it annually.

It affects 23 to 32 people per 100,000 older adults annually.


The primary sign of temporary global amnesia is the inability to form new memories and recall previous events. It’s critical to rule out other potential causes of forgetfulness after that symptom has been proven.

For temporary global amnesia to be diagnosed, you need to exhibit these signs and symptoms:

  • Witness reports of sudden onset of confusion, including memory loss
  • Despite memory loss, being aware of who you are, staying up and being vigilant
  • Typical cognitive abilities include the capacity to identify and label well-known items and adhere to basic instructions.
  • No symptoms of specific brain damage, such as loss of mobility in one arm or leg, uncontrollable motions, or difficulty understanding speech

Additional signs and past events that could aid in the diagnosis of temporary global amnesia include the following:

  • symptoms that usually subside in less than 24 hours
  • Memory gradually returning No recent head trauma
  • There were no seizure symptoms while the amnesia was occurring
  • absence of past epileptic episodes

Repetitive asking of the same question, such as “What am I doing here?” or “How did we get here?” is another typical symptom of transitory global amnesia brought on by the incapacity to form new memories.

When to visit a physician

Anyone who moves from normal knowledge of the present reality to uncertainty about what just happened should seek emergency medical assistance. Make an ambulance call yourself if the person who is having memory loss is too disoriented to do so.

Temporary worldwide amnesia poses no threat. However, it can be difficult to distinguish between the life-threatening conditions that can potentially induce abrupt memory loss and temporary global amnesia.

Why can temporary worldwide amnesia occur?

Researchers are unsure of the precise reason for temporary worldwide amnesia (TGA). However, they think it’s caused by a transient problem in your hippocampal region, which is an important area of the brain involved in memory and learning.

According to certain research, TGA may be caused by inadequate blood flow (ischemia) or oxygen flow (hypoxia) to the brain. According to another study, TGA may be connected to your brain’s seizure activity.

  • TGA can occur in certain circumstances, such as physical activity.
  • psychological or emotional strain.
  • abrupt submersion in hot or cold water.
  • Pain.
  • Sexual activity.

Applying the Valsalva technique. This is a deliberate breathing exercise used to lower an elevated heart rate or as part of a medical examination. It entails bearing down as though having a bowel movement, closing your lips, and pinching your nose.

Benign transitory amnesia following drug ingestion (TGA) can arise from any of the following:

  • excessive consumption of alcohol.
  • use a lot of barbiturates (sedatives and sleep-inducing drugs).
  • using multiple substances for fun.
  • using benzodiazepines in modest amounts (drugs that treat anxiety, insomnia, and seizures).
  • You should visit the hospital right away if you or a loved one is experiencing abrupt memory loss symptoms to be sure there isn’t a possibly fatal illness causing it.

Factors at risk

It’s interesting to note that, despite being strongly associated with strokes, high blood pressure and high cholesterol have been shown in numerous studies to not be risk factors for temporary global amnesia. This is most likely due to the fact that temporary worldwide amnesia is not indicative of ageing blood vessel disorders. Neither your sex nor your risk appear to have an impact.

Age is the most obvious risk factor. Transient global amnesia is more common in those over 50 than in younger adults.

migraines’ past. The chance of temporary worldwide amnesia is much higher for migraine sufferers than for non-migraine sufferers.


There are no obvious concerns with transient global amnesia. It does not increase the risk of epilepsy or stroke. A second episode of transitory global amnesia is not unheard of, but it is unlikely to occur more than twice.

However, emotional anguish can result from even brief memory loss. Ask your doctor to go over the findings of your diagnostic tests and neurological examination with you if you need some peace of mind.

Diagnoses and Examinations

How is a diagnosis of transitory global amnesia made?

Transient global amnesia cannot be diagnosed using a test. Rather, before diagnosing TGA, medical professionals should clear out all other potential reasons for forgetfulness.

Your vital signs and physical examination will be performed by a provider in order to rule out other explanations. They might also conduct a neurological examination.

They might request particular blood tests and imaging studies, like:

  • Thorough metabolic panel.
  • Toxicology screen (drug test)
  • Handling and Medical Interventions

How is temporary worldwide amnesia managed?

Transient global amnesia has no known cure. Your memory function will return to normal once the problem resolves on its own in a day or two.

Your medical team would probably advise you to stay in the hospital until the amnesia goes away in order to rule out any underlying medical conditions and to ensure that you don’t have any new symptoms.

What consequences does temporary worldwide amnesia have in the long run?

Transient global amnesia typically has no lasting consequences. For the most part, TGA patients recover totally. They will not recall the events of the episode, but they will be able to create new memories after it is over. Most other recent memories come back in a day or two.

Rarely, temporary global conditions cause persistent memory problems. This problem usually only affects those who experience recurrent bouts. Less than 10% of people who have temporary global amnesia (TGA) go on to experience further episodes.

Is TGA a mini stroke?

Answer: There is more to transient global amnesia (TGA) than a small stroke (transient ischemic attack). Despite having the same term in their names and the quick onset of symptoms, the illnesses are not the same.

The primary symptom of TGA is sudden memory loss, which is also typically the sole one. Similar symptoms to strokes can be found in mini strokes, including:

  • inability to see with one or both eyes.
  • Your face, arms, or legs may feel numb or weak, especially on one side.
  • Severe headache.

It’s critical to seek emergency department care as soon as stroke symptoms arise in order to receive timely medical attention.

What causes transient global amnesia?

Answer: It is unknown what causes temporary global amnesia. Individuals over 50 are more susceptible to TGA. Studies indicate that there might be a connection between TGA sufferers and individuals who have a history of migraines. Most of the time, nothing happens to cause a brief bout of global amnesia.

Is transient global amnesia caused by stress?

Answer: Acute-onset anterograde amnesia with a transient duration is known as transient global amnesia (TGA), and it typically affects middle-aged and older people. It can be brought on by highly taxing activities, stressful situations, or coitus, but migraines can also cause it.

Is transient global amnesia normal?

Answer: A rare clinical phenomenon known as transient global amnesia (TGA) affects 5.2–10/100,000 people in the general population and 23.5–32/100,000 people over the age of 50 annually [1].

Is there a cure for transient global amnesia?

Answer: Transient global amnesia does not require medical attention. It has no known long-term effects and gets better on its own without therapy.

Is transient global amnesia curable?

Answer: The sudden loss of short-term memory caused by transient global amnesia (TGA) usually goes away on its own in a day or two. Even if the illness is benign, it’s crucial to get medical attention right away if you or a loved one experiences unexpected memory loss so that you can be certain there isn’t a more dangerous underlying reason.

What age is transient global amnesia?

Answer: Patients with transient global amnesia are typically between 40 and 80 years old. Individuals suffering from this disorder are frequently mislabeled as confused. The classic presentation is sudden onset of acute anterograde amnesia. Usually, it is followed by incessant inquiry.
