Brief Summary

The goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one ...

Detailed Description

This study aims to test the efficacy of a non-pharmacological treatment for MCI that involves noninvasive brain stimulation (NIBS). Early studies in Alzheimer's disease (AD) dementia patients have fou...

Eligibility Criteria

Inclusion

  • Both Veterans and Non-Veterans may enroll if they meet the following criteria \*\*
  • Diagnosed with amnestic Mild Cognitive Impairment (aMCI);
  • Stable medications (including any dementia-related meds) for at least 4 weeks prior to Baseline;
  • Geriatric Depression Scale score less than 6;
  • Ability to obtain a motor threshold, determined during the screening process;
  • Study partner available; living situation enables attendance at clinic visits;
  • Visual and auditory acuity adequate for neuropsychological testing;
  • Good general health with no diseases expected to interfere with the study;
  • Participant is not pregnant or of childbearing potential (i.e. women must be 2 years post-menopausal or surgically sterile);
  • Modified Hachinski Ischemic score less than or equal to 4;
  • Agree to DNA extraction for single nucleotide polymorphism (SNP) genotyping;
  • Able to understand study procedures and comply with them for the entire length of the study.

Exclusion

  • Prior exposure to rTMS within the past 12 months;
  • Magnetic field safety concern such as a cardiac pacemaker, cochlear implant, implanted device in the brain (deep brain stimulation), or metal fragments or foreign objects in the eyes, skin or body;
  • Any significant neurological disease other than suspected incipient Alzheimer's disease;
  • Unstable cardiac disease or recent (\< 3 months previous) myocardial infarction. Any significant systemic illness or unstable medical condition that could lead to difficulty with protocol adherence;
  • History of epilepsy or repetitive seizures, as determined by patient report or chart review;
  • History of a medical condition or current use/abuse of medications and substances that increase the risk of a seizure, specifically:
  • Traumatic brain injury within 2 months that would increase the risk for seizure;
  • Unable to safely withdraw, at least 4 weeks prior to Baseline, from medications that substantially increase the risk of having seizures (for example: theophylline, clozapine, and methylphenidate).
  • Current or past history of a mass lesion, cerebral infarct, or other noncognitive active neurological disease that would increase the risk for seizure.
  • Stimulant abuse within the previous 90 days. Cocaine and abuse of amphetamine and methylphenidate are associated with an increased risk of seizures;
  • Major depression or bipolar disorder (DSM-IV) within the past 1 year, or psychotic features within the last 3 months that could lead to difficulty with protocol adherence;
  • Taking sedative hypnotics or medications with anti-cholinergic properties and unable to withdraw at least 4 weeks prior to Baseline;
  • Current alcohol or substance abuse (not including caffeine or nicotine) within the past 1 year, as determined by chart review, participant or study partner report, or greater than "moderate" alcohol use defined by the Quantity-Frequency-Variability Index (Cahalan, Cisin, \& Crossley, 1969);
  • Any contraindications for magnetic resonance imaging (MRI) studies, e.g. severe claustrophobia, weight above 350 lb maximum allowed by MRI scanner, pregnancy;
  • Participation in another concurrent clinical trial;
  • Inability or unwillingness of individual or legal representative to give written informed consent.
