Improvement of memory for mild cognitive impairment with transcranial alternating current stimulation (tACS) performed by EEG and MRI: A randomized, two parallel group, double-blind study
Zusammenfassung der Studie
The proposed study will systematically examine the feasibility and efficacy of tACS for elderly individuals with memory loss. This study will provide data to support the safety and efficacy of tACS. tACS will be applied repeatedly at home in this population. This may lead to future research to introduce tACS in the prevention and treatment of memory loss in elderly individuals who do not have the time to travel to a clinic due to disability or who live too far away.

Untersuchte Intervention
The study is randomized, controlled, with two parallel groups and double-blind. It includes 12 weeks of daily stimulation sessions at home. Participants with mild cognitive impairment (MCI) are randomly assigned to an active/real group or placebo/control group. We will measure the change in memory scores between baseline and follow-up at 1 and 3 months. Memory values are measured with various questionnaires and neuropsychological tasks.

• Age ≥55 years • Clinical diagnosis of mild cognitive impairment (MCI) through the Memory Center, HUG procedure • Confirmation of the diagnosis by the study physician based on a holistic view of the cognitive assessment and the participant's history • Understanding of the information and consent statement • Able and willing to meet all study requirements • The consent statement has been signed (BASEC)
Ausschlusskriterien
• Age <55 years • any current diagnosis of a psychiatric disorder (e.g., schizophrenia, bipolar disorder, depressive disorder) • Except for MCI, any history of any other progressive or genetic neurological disease (e.g., Parkinson's disease, multiple sclerosis, tuberous sclerosis) or acquired neurological disease (e.g., stroke, traumatic brain injury, tumor), including intracranial lesions • History of traumatic brain injury resulting in persistent loss of consciousness • Recent history of poorly controlled headaches, including chronic medications for migraine prevention • History of fainting of unknown or indeterminate etiology that may represent seizures • History of seizures, diagnosis of epilepsy • Any unstable or uncontrolled chronic medical condition that, in the event of a provoked seizure, may lead to a medical emergency (heart defect, cardiac arrhythmia, asthma, etc.) • Contraindication for an MRI or the use of tACS • Any metallic body in the brain or skull (except dental fillings) or elsewhere in the body, unless approved by the responsible treating physician (e.g., MRI-compatible joint replacement) • Any device such as a pacemaker, drug pump, nerve stimulator, unless approved by the responsible treating physician (BASEC)
