Detailed Description
Melatonin production gets disrupted in AD, as shown in post-mortem pineal glands and CSF of AD patients. CSF melatonin levels are known to significantly drop in patients with Alzheimer's dementia. It is known that CSF melatonin levels are much higher than blood melatonin levels, due to melatonin secretion from the pineal recess directly into the third ventricle. It has never been investigated whether blood melatonin accurately correlates with CSF melatonin in AD, nor whether saliva or urine melatonin levels accurately reflect blood/CSF melatonin in the AD continuum. The investigators want to validate the use of blood, saliva and urine melatonin levels as alternative for CSF melatonin in the AD continuum to pave the way for further use of less invasive collection techniques (blood, saliva, urine instead of CSF) and to possibly study circadian rhythm in a less disrupting, in home environment (saliva, urine).
Furhtermore, melatonin exerts several potential anti-AD properties, including anti-inflammatory, anti-oxidant, tilting APP processing towards the non-amyloidogenic pathway, exerting positive effects on sleep and so on. In vivo studies furthermore point to anticonvulsive and antiepileptic effects of melatonin in a whole range of rodent models. Some evidence exists for a role of melatonin in prevention of epileptic seizures in humans.
The investigators want to investigate influence of melatonin on changes in cognition in a longitudinal way, and investigate influence on (sub)clinical epileptiform activity.
