Mild Motor Signs in Healthy Aging Are Associated with Lower Synaptic Density in the Brain.

Objective: To investigate whether mild motor signs (MMS) in old age correlate with synaptic density in the brain.

Background: Normal aging is associated with a decline in movement quality and quantity, commonly termed "mild parkinsonian signs" or more recently MMS. Whether MMS stem from global brain aging or pathology within motor circuits remains unresolved.

Can perfusion CT unmask postictal stroke mimics? A case-control study of 133 patients.

Objective: To study the diagnostic value of volume perfusion CT (VPCT) in patients with transient focal neurologic deficits following and during epileptic seizures, that mimic symptoms of stroke.

Methods: A retrospective case-control study was performed on 159 patients who presented with a seizure and received an emergency VPCT within the first 3.5 hours of admission, after being misjudged to have an acute stroke.
