Striatal dopamine transmission and prodromal markers of α-synucleinopathy neurodegeneration in recurrent dream enactment behaviors without REM sleep without atonia: a case-control study

Brief description

Idiopathic rapid eye movement sleep behavior disorder (iRBD) is a novel and distinct parasomnia characterized by recurrent dream enactment behaviors (DEBs) and REM sleep without atonia (RSWA) during polysomnographic assessment, with a male predominance and typical onset age at early 60’s.

This study is a case-control study, which aims to determine whether recurrent DEBs without sufficient RSWA represents an early stage of α-synucleinopathy.

Study Details

Subjects will undergo a comprehensive survey of neurodegenerative markers, including

  • cognitive functions,
  • PET scan (striatal dopamine transmission)
  • video-polysomnography assessment
  • blood test
