Dementia

Dementia was an amnesia inducing product invented by Lumbaegan Pepper scientist Dr Dementia in 1963. 
Dementia was originally designed to allow consumers to selectively forget certain experiences or information such as traumatic experiences or experiences they wished to live again for the first time. At first, Dementia was very popular and Dr Dementia made several million pounds from its sale, but in 1967 Jospeh Stalin ordered his scientists to covertly modify Dementia so it would become infectious and cause users to forget everything, including basic bodily functions as does the disease of the same name. Though Dementia did not become infectious, it did indeed cause users to forget everything and was almost immediately outlawed in almost every country in the world, with Dr Dementia being blamed and vilified by the public for his assumed responsibility for its fatal effects.
