Treating alcoholism and preventing alcohol and illicit drug use can prevent further damage, but in most cases will not recover lost memory.Although improvements occur when patients receive certain treatments, there is still no actual cure remedy for amnesia so far. To what extent the patient recovers and how long the amnesia will continue depends on the type and severity of the lesion. History
French psychologist Theodule-Armand Ribot was among the first scientists to study amnesia. He proposed Ribots Law which states that there is a time gradient in retrograde amnesia. The law follows a logical progression of memory loss due to disease. First, a patient loses the recent memories, then personal memories, and finally intellectual memories. He implied that the most recent memories were lost first.Case studies have played a large role in the discovery of amnesia and the parts of the brain that were affected. The studies gave important insight into how amnesia affects the brain. The studies also gave scientists the resources into improving their knowledge about amnesia and insight into a cure or prevention. There are several extremely important case studies: Henry Molaison, R.B, and G.D.

Henry Molaison
Henry Molaison, formerly known as H.M., changed the way people thought of memory. The case was first reported in a paper by William Beecher Scoville and Brenda Milner in 1957. He was a patient who had  severe epilepsy attributed to a bicycle accident at the age of nine.
Pseudolymphoma is a benign lymphocytic infiltrate that resembles cutaneous lymphoma histologically, clinically, or both. Lymphoma cutis is the most important type of pseudolymphoma. Presentation
It manifests with diarrhoea, hepatosplenomegaly, moderate lymph node enlargement without histopathological changes and evidence of the reticulo-endothelial system involvement. Cause
It is an adverse effect of phenytoin. Diagnosis
