<unk>  <unk>  is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of<unk>  exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of consciousness, as well as possibly a few deeply encoded facts of the individual's past, such as their childhood, family, or home perhaps. Both<unk>  and anterograde amnesia deal with disruptions of short-term memory. However, a<unk>  episode generally lasts no more than 2 to 8 hours before the patient returns to normal with the ability to form new memories. A patient with anterograde amnesia may not be able to form new memories indefinitely.
