Illness, though much rarer, can also cause anterograde amnesia if it causes encephalitis, which is the inflammation of brain tissue. There are several types of encephalitis: one such is herpes simplex encephalitis (HSV), which, if left untreated, can lead to neurological deterioration. How HSV gains access to the brain is unknown.
Individuals with retrograde amnesia may partially regain memory later, but memories are not regained with anterograde amnesia because they were not encoded properly. [ 8 ] The term "post-traumatic amnesia" was first used in 1940 in a paper by Symonds to refer to the period between the injury and the return of full, continuous memory, including ...
Having longer periods of amnesia or consciousness after an injury may be an indication that recovery from remaining concussion symptoms will take much longer.

Wernicke encephalopathy typically presents with ataxia and nystagmus, and Korsakoff's psychosis with anterograde and retrograde amnesia and confabulation upon relevant lines of questioning. [ 25 ] Frequently, secondary to thiamine deficiency and subsequent cytotoxic edema in Wernicke encephalopathy, patients will have marked degeneration of the ...
Re-experiencing symptoms of trauma can be quite varied and personal. For instance, you might see someone who reminds you of the person who hurt you and suddenly feel a familiar intense fear.
Amnesia is an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient. [5] There are two forms of amnesia: Anterograde amnesia and retrograde amnesia, that show hippocampal or medial temporal lobe damage.
