Benefits of MRI for Patients With Low-risk Transient or Persistent Minor Neurologic Deficits
More than 1 million patients receive a diagnosis of stroke or transient ischemic attack (TIA) in the United States each year. These patients are at increased risk of stroke during the first few weeks after the initial event, with the greatest risk during the first 2 days. Evidence-based secondary preventive measures are available to lower the risk of recurrent ischemic events, but for these measures to be effectively implemented, patients with stroke or TIA must be rapidly and correctly identified. Accurate diagnosis is important because some secondary preventive strategies carry risks of their own and are usually not appr...

Treatment of Poststroke Aphasia With Transcranial Direct Current Stimulation
Stroke remains a leading cause of human disability. Important gains have been realized in the setting of acute ischemic stroke, where thrombolytic and catheter-based reperfusion therapies can substantially improve long-term behavioral outcomes. However, most patients with a new stroke are not eligible for such therapies because of delays in diagnosis or hemorrhagic etiology, for example, and many who are treated nonetheless have substantial long-term disability. Additional classes of poststroke therapy are needed.

Transcranial Direct Current Stimulation to Treat Aphasia After Stroke
This randomized clinical trial examines the futility of studying anodal transcranial direct current stimulation vs sham stimulation as an adjunctive intervention during speech therapy to improve speech production (naming) for older adults with long-term poststroke aphasia.
