People with extensive, bilateral hippocampal damage may experience anterograde amnesia: the inability to form and retain new memories.

There are two main types of amnesia: retrograde amnesia and anterograde amnesia.

High doses of many shorter-acting benzodiazepines may also cause anterograde amnesia and dissociation.
Retrograde amnesia

Loss of memory-access to events that occurred or information that was learned in the past.
Anterograde amnesia is a similar condition that deals with the inability to form new memories following the onset of an injury or disease.
Long-term memory
8 linksStage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely.
Stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely.
His subsequent total anterograde amnesia and partial retrograde amnesia provided the first evidence for the localization of memory function, and further clarified the differences between declarative and procedural memory.

Systematic studies of anterograde amnesia started to emerge in the 1960s and 1970s.
Short-term memory

Capacity for holding a small amount of information in an active, readily available state for a short interval.
One form of evidence cited in favor of the existence of a short-term store comes from anterograde amnesia, the inability to learn new facts and episodes.
Lorazepam

Benzodiazepine medication.
It is also used during surgery to interfere with memory formation and to sedate those who are being mechanically ventilated.
Henry Molaison
5 linksAmerican who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.
American who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy.
After the surgery, which was partially successful in controlling his seizures, Molaison developed severe anterograde amnesia: although his working memory and procedural memory were intact, he could not commit new events to his explicit memory.
Episodic memory
7 linksMemory of everyday events that can be explicitly stated or conjured.
Memory of everyday events that can be explicitly stated or conjured.
For example, anterograde amnesia, from damage of the medial temporal lobe, is an impairment of declarative memory that affects both episodic and semantic memory operations.
