What is the scientific term for compulsive documenting of life experiences? I'm posting this question on someone else's behalf:


  What is the name for someone who has a compulsive need to
  categorically document everything they do and everything that happens
  to them?
  
  The only thing I can think of is "information hoarder" but suggests
  that any type of information will do, which is not what I'm looking
  for.
Hypergraphia is a behavioral condition characterized by the intense desire to write. 


-wikipedia hypergraphia

Its difficult to tell if this is hypergraphia but that is the closest mental illness to which I am aware. If she is just writing in their journal "today I went to the store and met suzy and we went for coffee then I came home and watched tv" it would not be hypergraphia. Hypergraphia would be a compulsion to write large amounts which are rational outlines or nonsense. 

There are medications to relieve some of the compulsions to write based on the cause of the hypergraphia.
