Modulation of Cognition and Brain Connectivity by Noninvasive Brain Stimulation in Patients With Mild Cognitive Impairment Due to Alzheimer's Disease

2019-07-15 10:05:52 | BioPortfolio

Summary

Alzheimer's disease (AD) has a detrimental impact on cognitive functions. Based on pilot studies results in patients with neurodegenerative brain diseases the investigators aim for promoting the brain plasticity and improving cognition by noninvasive brain stimulation (NIBS) in healthy young, healthy aged and subjects with mild cognitive impairment due to AD. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more-serious decline of dementia. Different new brain targets, cognitive tasks and stimulation protocols will be tested and optimized for specific subject groups. Design of a functional MRI (fMRI) - repetitive transcranial magnetic stimulation (rTMS) - fMRI study will enable us to explore and identify effect of age, presence of the disease and genetic risk factor (APOE4) on repetitive transcranial magnetic stimulation (rTMS)-induced changes in cognition and related brain connectivity/activations. The study results will improve our understanding of healthy and pathological brain aging and will provide novel information about the usefulness of NIBS in specific subject groups. These results will have an important impact on future non-pharmacological treatment strategies.

Description

Intensified intermittent theta-burst stimulation (iTBS) protocol will be applied in the MCI study group. A two-parallel-group, randomized, placebo controlled design will be used. Ten MCI subjects will be stimulated in a week-long therapeutical sessions. Other ten MCI subjects will be stimulated with the same protocol using sham stimulation. The investigators will study the change in subjects immediately after and again at a two-weeks follow-up visit after the end of the last stimulation session.

Medical and Biotech [MESH] Definitions

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.

Measurable changes in activities in the CEREBRAL CORTEX upon a stimulation. A change in cortical excitability as measured by various techniques (e.g., TRANSCRANIAL MAGNETIC STIMULATION) is associated with brain disorders.

A technique of brain electric stimulation therapy which uses constant, low current delivered via ELECTRODES placed on various locations on the scalp.

A condition of low alertness or cognitive impairment, usually associated with prolonged mental activities or stress.

A technique that involves the use of electrical coils on the head to generate a brief magnetic field which reaches the CEREBRAL CORTEX. It is coupled with ELECTROMYOGRAPHY response detection to assess cortical excitability by the threshold required to induce MOTOR EVOKED POTENTIALS. This method is also used for BRAIN MAPPING, to study NEUROPHYSIOLOGY, and as a substitute for ELECTROCONVULSIVE THERAPY for treating DEPRESSION. Induction of SEIZURES limits its clinical usage.
