P 83 Parasomnia, parkinsonism, impulse control disorder and bulbar palsy with IgLON5 antibodies: A new case report

In 2014 a complex neurological syndrome with parasomnia, sleep breathing dysfunction and variable bulbar symptoms associated with antibodies to IgLON5, a neuronal cell-adhesion protein, was described (Sabater et al., 2016). Postmortal studies revealed tauopathy predominately involving the hypothalamus and tegmentum of the brainstem (Gelpi et al., 2016). To the best of our knowledge, there are 16 published cases so far.
