Effects of Sleep Deprivation on Cerebrospinal Fluid (CSF) Amyloid-beta (Aβ) Dynamics (AWAKE)
Losing Sleep Over Alzheimer's Disease? Effects of Sleep Deprivation on Cerebrospinal Fluid Amyloid-beta Dynamics
Introduction: Alzheimer's disease (AD) is characterized by neurodegeneration of the brain in the form of neurofibrillary tangles and plaques containing the amyloid-beta protein (Abeta). Recent animal studies have shown that extended wakefulness is associated with increased production of these Abeta proteins and that sleep leads to a marked fall in their production.
Aim: The investigators aim to distinguish a similar effect of sleep disturbance on cerebrospinal fluid (CSF) Abeta levels in humans, which may point out sleep disturbance as an important factor in AD development.
Methods: a study in 26 healthy male volunteers, measuring CSF Abeta levels during a sleep deprivation night and before and after a control night with unrestricted sleep.
Expected results: The investigators expect sleep deprivation to lead to an increase in CSF Abeta levels, as compared to the levels in the control night.

Amyloid beta
Tidsramme: 6 timepoints during one night of sleep deprivation

Subjects will undergo one night of sleep deprivation before, during and after which a total of 9 CSF samples (6ml each) will be drawn through a spinal catheter.
From these CSF samples Amyloid beta will be analysed.
