It is only when these symptoms appear regularly that there is cause for concern. Amnesia caused by substance use is a far more worrying symptom, but it may be common even for social drinkers. Blackout Defined. A blackout is a loss of memory caused by excessive alcohol intake or drug use. These substances cause disruption to the ability of the brain to form long-term memories. This interference occurs at the hippocampus region of the brain. The loss of memory can be fragmentary or complete. It does not damage previous long-term memories. The occurrence of this type of memory loss is usually associated with a rapid rise in blood alcohol content.
Neurological amnesias are caused by specific kinds of damage to the brain, generally in the region where the hippocampus is located. The famous case of patient H.M. is a highly revealing example of the importance of this region.
