Further characterization of patients with amnesia after cardiac arrest: preserved recognition memory
Abstract:
We observed that patients with amnesia after cardiac arrest had preserved recognition memory despite profound loss of recall memory. In the present study, rate of forgetting was measured in six amnesic subjects for both recall and recognition memory of verbal material. The data show that recall decayed significantly faster for the amnesic subjects than for controls, whereas the rate of forgetting for recognition memory was comparable in both groups. Dissociation between recall and recognition performance is a feature of the amnesic syndrome after cardiac arrest.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
