There is some evidence in literature of concurrent psychiatric symptoms,
particularly psychotic symptoms, associated with Usher's syndrome, and
several theories around this association have been proposed.

These theories of associations include a genetic link between the genes
responsible for schizophrenia and the genes for Usher's syndrome; a
neuropathological explanation as radiologic studies have revealed that
patients with Usher's syndrome have CNS abnormalities in multiple brain
structures; and a sensory deficit model which proposes that the
stressors associated with sensory impairment and the brain's adaptation
to changes in sensory inputs place an individual at increased risk for
psychopathology.
