Visual snow likely represents a clinical continuum, with different degrees of severity. On the severe end of the spectrum, it is more likely to present with its common comorbid conditions, migraine and tinnitus. Visual snow does not depend on the effect of psychotropic substances on the brain.DSM-V=Diagnostic and Statistical Manual of Mental Disorders, 5th edition; HPPD=hallucinogen persisting perception disorder; VS=visual snow; VSS=visual snow syndrome
