What is the cause of sudden transient amnesia in the brain

It is recommended to seek medical attention from a neurology or psychiatry department for sudden transient amnesia in the brain, which may be related to factors such as transient ischemic attacks, epilepsy, migraines, psychological stress reactions, and sequelae of traumatic brain injury.

1. Neurology

Neurology mainly investigates organic lesions. Transient ischemic attack is a common trigger, and due to temporary cerebral vascular insufficiency, memory function may be temporarily interrupted, leading to speech ambiguity or limb numbness in patients. Seizures, especially temporal lobe epilepsy, may be accompanied by several minutes of memory loss, and EEG examination can assist in diagnosis. Migraine accompanied by transient total amnesia often lasts for several hours and usually does not require special treatment. Mild traumatic brain injury such as concussion may also cause retrograde amnesia, and intracranial hemorrhage should be ruled out in conjunction with imaging.

2. Psychologist

Psychological factors leading to dissociative forgetting require evaluation by a psychiatrist. Acute stress response may trigger psychogenic amnesia, with patients experiencing significant emotional triggering events and selective memory loss. Overventilation syndrome during anxiety attacks can cause hypoxemic memory interruption in the brain, accompanied by symptoms such as numbness in the hands and feet. Temporary inhibition of cognitive function caused by sleep deprivation or chronic stress also belongs to this category, and psychological scale assessment can assist in judgment. Some patients with depression may exhibit pseudo dementia symptoms, which need to be differentiated from organic diseases.

It is necessary to maintain a regular daily routine and moderate exercise to avoid staying up late and excessive fatigue. hypertension and diabetes patients should strictly control basic diseases and reduce vascular risk factors. When sudden amnesia is accompanied by headache, vomiting, or limb paralysis, immediate medical attention should be sought. Recording the frequency and duration of the attacks can help doctors determine the cause. Diet can include deep-sea fish and nut based foods, and moderate supplementation of B vitamins can help with neuroprotection, but all treatments must be carried out under the guidance of a professional physician.
