Transient global amnesia (transient global amnesia) is a condition in which a person suddenly loses memory for a period of time, often accompanied by confusion. This condition often occurs in middle-aged and older people.
People with transient global amnesia often suddenly cannot recall recent events or information. However, they may remember who they are, recall the names of familiar objects, and recognize family members who are important to their lives.
A transient amnesia episode can last up to 24 hours or less, with an average of 6 hours. During this time, the person is unable to create or store new information or memories. They may ask the same questions over and over again because they cannot remember and retain information in their mind. A transient amnesia episode is usually sudden, but recovery is gradual.
The cause of transient global amnesia is unknown. Certain brain diseases or abnormalities may be risk factors, including migraines, excessive stress, overexertion, pain, sudden immersion in cold or hot water, heavy alcohol consumption, and stimulant use. Head trauma, tumors, or strokes can also cause this condition.
Your father had temporary amnesia for about half a day. Although his memory has returned to normal, he should not be subjective. The family should take him to a medical facility with a neurology department for a specific assessment. The doctor will take his medical history and ask for a detailed description of the recent temporary amnesia. At the same time, the doctor will have the patient do neurological tests to assess sensory function, reflexes, memory, gait, balance and coordination.
The doctor may also order an MRI or CT scan of the brain, or an EEG to detect other abnormalities such as tumors, vascular malformations, blood flow to the brain, or electrical function of the brain. Depending on the cause and the case, the doctor will advise and prescribe appropriate treatment.
