Graphorrhea

Graphorrhea is a communication disorder involving excessive wordiness, incoherent rambling, or frequent digressions in writing. Graphorrhea is most commonly associated with schizophrenia. However, it can also result from other psychiatric disorders such as aphasia and mania or neurological disorders like temporal lobe epilepsy and brain lesions. The ramblings may be grammatically correct, but still leave the reader confused and unsure what the piece is about.
