Imaging Post-Stroke Recovery: Using MEG to Evaluate Cognition

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a study using magnetoencephalography (MEG) to look at recovery in those with minor stroke. The investigators know that these individuals report difficulties in attention, concentration, multi-tasking, energy level, and processing speed that appear to be independent of lesion size or location. The underlying pathophysiology is unclear; however, anecdotally, many individuals are significantly improved by 6 months post-stroke. One hypothesis is that a single lesion, regardless of size, may disrupt the classic neural networks required for cognitive function. The investigators are currently collecting data to better characterize these difficulties and stroke patients' recovery as part of a previously approved recovery study. In this sub-study, the investigators propose to add MEG at 1 and 6 months in a subset of individuals with small: 1) subcortical, and 2) cortical lesions. The investigators will partner with colleagues at the University of Maryland (College Park), who are well experienced with MEG to conduct this research. In addition a control population of age-similar individuals will be recruited for comparison. Cerebral activation patterns of individuals with stroke versus controls will be compared, both across patients with stroke at a given time point, and within subjects from 1 to 6 months to determine the association of abnormal activation with cognitive dysfunction and recovery. \*\*The investigators have recently extended follow-up by adding an additional assessment at 12 months and will enroll additional participants (up to 40 patients with minor stroke, 15 age-similar controls).

Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:Not specified
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. 1. Adults (≥18 years) admitted to Bayview Medical Center Neurology.
  2. 2. Evidence of acute ischemic stroke (CT or MRI)- lacunar stroke or branch occlusion (M3/A3/P3 or smaller) OR NIHSS ≤ 8 on admission.
  3. 3. Competent speaker of English (by self or family report) prior to stroke.
  4. 4. Return for follow-up 4-6 weeks post event (+/- 4 wks).
  5. 5. Cognitive deficits present on initial testing.\*\* unique to MEG study
  6. 6. Willing to travel to the University of Maryland twice for MEG.\*\* unique to MEG study
  7. 7. Fully independent functionally and able to travel to the University of Maryland unassisted.\*\* unique to MEG study
  1. 1. Primary intracerebral hemorrhage- as evidenced by blood on head CT or MRI.
  2. 2. Previous neurological disease (e.g., dementia, multiple sclerosis, prior symptomatic stroke). Incidental asymptomatic lacunar strokes found on imaging will not be excluded as prior disease.
  3. 3. Uncorrected hearing or visual loss.
  4. 4. Large vessel occlusion.
  5. 5. Presence of any of the following that would lead to significant artifact on MEG: cardiac pacemaker, intracranial clips, metal implants, or external clips within 10mm of the head, metal in the eyes.\*\* unique to MEG study
  6. 6. Claustrophobia, obesity, and/or any other reason leading to difficulty staying in the MEG for up to 1 hour.\*\* unique to MEG study
  7. 7. For controls- clinical history of stroke or other neurological dysfunction (seizure, multiple sclerosis, etc.); psychiatric disease
