What is the author's style in Motherless Brooklyn by Jonathan Lethem?

With the exception of the first half of the second-to-last chapter, the book is told entirely in the first person point of view of Lionel Essrog, an unlicensed ‘detective’ on the hunt for the man responsible for his mentor’s death. He suffers from Tourette’s syndrome, a compulsive condition that prompts him to rearrange words and phrases in often profound and profane ways both in dialogue and in narration. This imposes extreme influence on the novel as a whole.
