Causes of Amnesia

The most important factors causing amnesia are:

  • Alcohol/malnutrition - In Wernicke- Korsakoff syndrome, the memory centers of the brain are damaged due to excessive use of alcohol, or malnutrition, depriving the brain cells of vital nutrients.
  • Infections - Encephalitis and herpes induce brain tissue damage that could result in amnesia.
  • Psychological - Amnesia can be caused by psychological factors when it is referred to as psychogenic.
  • Injury - Amnesia is most commonly associated with brain damage through injury caused by an accident, fall or a blow to the head.
  • Age - Degeneration of brain cells in dementia is another major cause of amnesia. As in physical injury, the brain cells that are damaged in a dementia patient cannot be replaced.
  • stroke - Memory loss can be brought about by stroke which results in impairment of brain cells in regions associated with memory loss.(3)

In the fall of 2009 I woke up in Cozumel with no memory of how I got there. I remembered planning the trip for our 30th wedding anniversary. However could not recall driving to the airport, the flight, layover, Etc... Needless to say My Wife was very concerned. After a while we assumed that the tequilla sunrise we may have been tainted [My Wife hardly touched hers]. Skip ahead to the summer of 2010. grand mal seizure upon awakening from a mid afternoon nap. Paramedics medevaced to Hospital. MRI, EEG, EKG, ETC... No abnormamities found. Since then. numerous nocturnal petit mal seizures. Doctors keep increasing dosage of Keppra. Early memories of childhood, adolescence, early adulthood appear to be intact. However, short term memory of people and places are vague to non-existent. I have been noticing a lot of chatter about bilirubin build up in brain. I want my memory back!
