Lewy Body Dementia

The New York Times Magazine ran an article today attributing Scrooge's "symptoms" to Lewy Body Dementia. (perhaps available here)

Dickens reports classic parkinsonian features such as masked facies, rigidity, shuffling gait, resting tremor in his description of Scrooge. If the visits Scrooge receives from the past, present, and future are considered visual hallucinations, his clinical picture is consistent with Lewy Body Dementia.

The article does not comment on the existence of Jiminy Cricket.
