What causes amnesia?
I often see on TV that people wake up with amnesia after suffering a head injury, so I would like to learn more about how amnesia works.
Doctor's answer (1)
Amnesia, also known as memory disorder or amnestic syndrome, is characterized by the inability to recall past experiences, personal information, or newly learned information. Its causes can be categorized into several major groups:
1. Cerebrovascular diseases: such as hippocampal structural damage caused by arterial ischemia, or transient global amnesia resulting from venous congestion and impaired blood return, which can lead to sudden memory loss.
2. Psychological factors: such as amnesia caused by psychological defense mechanisms, commonly seen after experiencing severe emotional trauma. Sometimes this type of amnesia is temporary and may improve over time.
3. Malnutrition: a lack of essential nutrients in the brain, such as proteins and vitamins, can affect the normal metabolism and physiological functions of brain nerves and cells, leading to amnesia.
4. Functional diseases: emotional fluctuations, hysteria attacks, and similar conditions can also cause amnesia, manifesting as confusion, mental dullness, and difficulty concentrating.
Treatment methods for amnesia include herbal regulation, acupuncture therapy, and cognitive behavioral therapy. Specific treatment plans should be formulated according to the patient's underlying cause and clinical condition.
