The reason for sudden transient amnesia in the brain at the age of 12

Sudden transient amnesia in a 12-year-old child may be related to factors such as sleep deprivation, emotional stress, hypoglycemia, seizures, and concussion. Transient global amnesia is relatively rare in children, but attention should be paid to neurological abnormalities.

1. Sleep deprivation

Long term sleep deprivation in children can lead to temporary inhibition of the hippocampus function, manifested as sudden fragmented memory loss. This situation usually occurs when staying up late continuously or having poor sleep quality, accompanied by decreased attention and delayed response. Establishing regular sleep habits and ensuring at least 9 hours of sleep per day can effectively prevent it.

2. Emotional stress

Acute stress reactions may trigger transient memory gaps, commonly seen in high-pressure scenarios such as exam anxiety or family conflicts. Elevated levels of stress hormones can disrupt neurotransmitter balance and cause memory loss lasting from seconds to minutes. Symptoms can be alleviated through mindfulness breathing training and psychological counseling.

3. Hypoglycemia

Failure to eat breakfast or engage in vigorous exercise may result in a sudden drop in blood sugar, leading to insufficient energy supply to the brain. In addition to memory interruption, the child often experiences cold sweat and hand tremors. Timely supplementation of sugary foods can quickly restore health. It is important to maintain a regular three meal diet and avoid prolonged fasting.

4. Seizures

Absence seizures in temporal lobe epilepsy can manifest as sudden memory loss, with no memory of the process after the seizure. This type of situation is often accompanied by eye gaze or slight twitching, and abnormal discharge can be seen on EEG examination. After diagnosis, it is necessary to follow the doctor's advice to take antiepileptic drugs such as sodium valproate for control.

5. Concussion

After minor head trauma, retrograde amnesia may occur, forgetting fragments before and after injury. This type of memory impairment is usually associated with concussion of brain tissue, which may be accompanied by headaches and nausea. Immediate cessation of exercise and medical examination are required. In severe cases, a head CT scan should be performed to rule out intracranial hemorrhage. Parents should record the frequency and causes of their children's amnesia attacks to avoid blaming and increasing their psychological burden. Ensuring a balanced diet, especially eggs and fish rich in lecithin, helps with nerve cell repair. Regular coordinated exercises such as skipping rope can enhance oxygen supply to the brain. If there are more than two episodes per month or accompanied by loss of consciousness, it is necessary to immediately go to the pediatric neurology department to investigate the cause, and if necessary, undergo in-depth examinations such as magnetic resonance imaging. Pay attention to avoiding children from participating in high-risk activities in daily life, and use safety seats in a standardized manner when riding.
