From the Research

Relationship Between Neuromyelitis Optica (NMO) and Charles Bonnet Syndrome (CBS)

  • There is no direct evidence in the provided studies to suggest a relationship between NMO and CBS.
  • NMO is a demyelinating disease of the central nervous system that predominantly affects the spinal cord and optic nerves 1, 2, 3, 4.
  • CBS is a condition in which people with vision loss experience complex visual hallucinations, which may be caused by increased excitability in the visual cortex 5.
  • While NMO can cause vision loss due to optic neuritis, which may be a risk factor for CBS, there is no study that directly investigates the relationship between the two conditions.
  • The provided studies focus on the pathophysiology and treatment of NMO 1, 2, 3, 4 and the neurochemistry and functional connectivity of CBS 5, but do not explore a potential link between the two conditions.
