A blackout is an example of a difficulty in encoding episodic memories due to alcohol. Blackouts are caused by a rapid increase in blood alcohol concentration (BAC) which in turn distorts the neurons in the hippocampus. [32] This distortion impairs a person's ability to form new episodic memories. [32]
Symptoms of varying BAC levels. Additional symptoms may occur. The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses.
A second cause is a traumatic brain injury in which damage is usually done to the hippocampus or surrounding cortices. It may also be caused by PTSD, a shocking event, or an emotional disorder. [5] Illness, though much rarer, can also cause anterograde amnesia if it causes encephalitis, which is the inflammation
