Objective Although small strokes typically result in “good” functional outcomes, significant cognitive impairment can occur. This longitudinal study examined a cohort of patients with minor stroke to determine the pattern of deficits, evolution over time, and factors associated with outcome. Methods Patients admitted to the hospital with their first clinical minor stroke (NIH Stroke Scale [NIHSS] ≤ 10, absence of severe hemiparesis, aphasia, or neglect) were assessed at 1 month post‐infarct, and a subset were followed over time (with 6‐ and 12‐month evaluations). Composite scores at each time point were generated for global cognition, verbal memory, spatial memory, motor speed, processing speed, and executive function. Paired t‐tests evaluated change in scores over time. Regression models identified factors associated with initial performance and better recovery. Results Eighty patients were enrolled, evaluated at 1 month, and prospectively followed. The average age of the participants was 62.3 years, and mean education was 13.5 years. The average stroke volume was 6.6 cc; mean NIHSS score was 2.8. At 1 month, cognitive scores were below the normative range and > 1 standard deviation below the patient's peak (“recovery”) score for every cognitive domain, strongly suggesting that they were well below patients’ prestroke baselines. Forty‐eight patients followed up at 6 months, and 39 at 12 months. Nearly all (98%) patients significantly improved in global cognition (averaged across domains) between 1 and 6 months. Between 6 and 12 months, recovery was variable. Higher education, occupational class, and Caucasian race were associated with higher recovery scores for most domains. Conclusions Cognitive impairment across multiple domains is common following minor stroke regardless of infarct location, suggesting a global process such as network dysfunction that improves over 6 months. Degree of recovery can be predicted using baseline factors.

Stroke patients with hemiparesis display decreased beta band (13–25 Hz) rolandic activity, correlating to impaired motor function. However, clinically, patients without significant weakness, with small lesions far from sensorimotor cortex, exhibit bilateral decreased motor dexterity and slowed reaction times. We investigate whether these minor stroke patients also display abnormal beta band activity. Magnetoencephalographic (MEG) data were collected from nine minor stroke patients (NIHSS < 4) without significant hemiparesis, at ~1 and ~6 months postinfarct, and eight age-similar controls. Rolandic relative beta power during matching tasks and resting state, and Beta Event Related (De)Synchronization (ERD/ERS) during button press responses were analyzed. Regardless of lesion location, patients had significantly reduced relative beta power and ERS compared to controls. Abnormalities persisted over visits, and were present in both ipsi- and contra-lesional hemispheres, consistent with bilateral impairments in motor dexterity and speed. Minor stroke patients without severe weakness display reduced rolandic beta band activity in both hemispheres, which may be linked to bilaterally impaired dexterity and processing speed, implicating global connectivity dysfunction affecting sensorimotor cortex independent of lesion location. Findings not only illustrate global network disruption after minor stroke, but suggest rolandic beta band activity may be a potential biomarker and treatment target, even for minor stroke patients with small lesions far from sensorimotor areas.

Background and Purpose: Stroke patients are currently monitored for neurological deterioration for 24 h following treatment with intravenous tissue plasminogen activator (IV tPA) or mechanical thrombectomy. This requires low nursing ratios and an intensive-care-like setting. As the half-life of IV tPA is short, many patients may not require such prolonged intensive monitoring and could be downgraded much earlier. We evaluate the frequency of neurological deterioration in the 0-12 and 12-24 h post-treatment windows. Methods: Patients presenting with acute ischemic stroke treated with IV tPA and/or thrombectomy at our institution from 2016-2018 were prospectively followed per protocol for 24 h post-therapy (examinations every 15 min for 2 h, every 30 min for 6 h, and hourly thereafter). Neurological deteriorations were recorded along with interventions and complications. Frequency of deterioration within the 0-12 and 12-24 h post-treatment windows was determined, along with factors associated with decline at each time point. Results: A total of 172 patients were treated (IV:135, IA:65, both:30). Thirty-six (21%) experienced a documented neurologic deterioration [8 due to intracerebral hemorrhage (4.7%)]. Five patients deteriorated in the 12-24 h window; all but one had experienced earlier examination changes. Elevated NIHSS was associated with a higher likelihood of deterioration overall. Early fluctuation was associated with decline after 12 h. Conclusions: New onset of neurologic deterioration is rare 12-24 h after treatment of acute stroke. Stable patients with low NIHSS scores and no ICU needs may not require intensive monitoring greater than 12 h post-treatment.

The use of telemedicine has increased significantly during the Corona virus disease 2019 pandemic. This manuscript serves to identify the underlying principles of clinical excellence in telemedicine and to determine whether effective care practices can be generalized as a one-size-fits-all model or must instead be tailored to individual patient populations.A survey assessing care quality and patient satisfaction for patients using telemedicine was created and administered via email to 2 urban cohorts of varying demographics and socioeconomic backgrounds: a population of patients with prior stroke and cerebrovascular disease, and a cohort of patients followed for interstitial lung disease. Results were compared across groups to determine the generalizability of effective practices across populations.Individuals taking part in telemedicine were more likely to be White, more affluent, and woman, regardless of clinical diagnosis compared with a similar cohort of patients seen in-person the year prior. A lower-than-expected number of patients who were Black and of lower socioeconomic status followed up virtually, indicating potential barriers to access. Overall, patients who participated in televisits were satisfied with the experience and felt that the care met their medical needs; however, those who were older were more likely to experience technical difficulties and prefer in-person visits, while those with less education were less likely to feel that their questions were addressed in an understandable way.When thoughtfully designed, telemedicine practices can be an effective model for patient care, though implementation must consider population characteristics including age, education, and socioeconomic status, and strategies such as ease of access versus optimization of communication strategies should be tailored to meet individual patient needs.
