• A stroke could cause amnesia due to neurological reasons.
• Infection with a virus, such as the herpes simplex virus, can cause brain inflammation.
• Autoimmune responses to cancer elsewhere in the body could cause inflammation which could result in amnesia.

• Lack of oxygen in the brain: This could happen as a result of a heart attack, breathing problems, or carbon monoxide poisoning.
• Long-term alcohol abuse can cause the body to have insufficient vitamin B. This condition is commonly known as Wernicke-Korsakoff syndrome.
• Tumors in the brain can cause disturbances in areas that control memory.
