[3][4] The Kandinsky–Clérambault syndrome remains relatively obscure in English-speaking countries and is mainly referenced by Russian, French, and German psychiatrists.

This was detailed in his posthumously published monograph, "On Pseudohallucinations" (Russian: О псевдогаллюцинациях), released in 1890 by his wife, Elizaveta Freimut.

[6] De Clérambault’s early research in 1909 focused on hallucinations, proposing that the mechanism of mental automatism could be responsible for hallucinatory experiences.

"[6] He defined these experiences as vivid, subjective perceptions that closely resemble real hallucinations, yet lack objective reality.

Kandinsky emphasised that these hallucinations were not simply products of imagination or memory, but were sensory, involuntary, and vivid.
