NCT04522960

Brief Summary

This is a long-term, prospective, observational study to investigate and compare the levels and rhythm of melatonin in patients with AD dementia, mild cognitive impairment due to AD and healthy volunteers. The investigators would like to validate the use of salivary and urine melatonin measurements as an alternative for blood/CSF melatonin. Furthermore, the investigators would like to assess the effects of melatonin levels on cognition by correlating the levels and changes on cognitive tasks over a two year time frame. The investigators will also investigate whether these effects could be due to its anticonvulsive properties.

Outcome Measures

Primary Outcomes (4)

  • CSF and blood melatonin levels in patients with AD dementia, MCI due to AD and healthy volunteers

    Comparison of CSF and blood melatonin levels between patients with MCI and dementia due to AD and healthy volunteers.

    24 hours

  • Blood, saliva and urine melatonin correlations

    Correlation between blood melatonin and urinary and salivary melatonin in the AD continuum

    24 hours

  • Melatonin influence on cognition

    Correlations between melatonin levels and cognitive performance over a 2 year time frame. This will be assessed by use of neuropsychological testing including MMSE, MoCA, RBANS, VAT, ...

    2 years

  • Melatonin influence on epileptiform activity

    Correlations between melatonin levels and (subclinical) epileptiform activity. Over a time frame of 8 weeks patients will undergo neuropsychological testing (with MMSE, MoCA, RBANS, VAT...), LTM-EEG monitoring (during 24 hours), MEG + hdEEG.

    8 weeks

Study Arms (2)

Patients with dementia or mild cognitive impairment due to AD

EXPERIMENTAL

Dementia or MCI due to AD according to NIA-AA research criteria.

Diagnostic Test: MEG+hdEEG+MRI

Healthy volunteers

ACTIVE COMPARATOR

Age-and-gender matched healthy controls.

Diagnostic Test: MEG+hdEEG+MRI

Interventions

MEG+hdEEG+MRIDIAGNOSTIC_TEST

We will perform several tests: * Neuropsychological testing to evaluate evolution of cognition during our study. * Lumbar puncture, blood sampling, saliva and urine collection to assess melatonin levels at several timepoints within these biological fluids. * MEG+hdEEG and MRI (to project MEG information) ; LTM-EEG to detect epileptiform activity in patients and healthy controls

Also known as: Lumbar puncture, Long-term EEG monitoring, Blood sampling, Saliva collection, Urine collection, Neuropsychological examination
