Cortical spreading depolarization (CSD), the neurophysiological event believed to underlie aura, may trigger migraine headaches through inflammatory signaling that originates in neurons and spreads to the meninges via astrocytes. Increasing evidence from studies on rodents and migraine patients supports this hypothesis. The transition from pro-inflammatory to anti-inflammatory mechanisms is crucial for resolving inflammation.

Background: In longitudinal studies of older persons, complete ascertainment of mortality is needed to minimize potential biases. To ascertain mortality in the National Health and Aging Trends Study (NHATS), investigators are advised to use its Sensitive files, which include month and year of death on most decedents who had not dropped out of the study. Because losses to follow-up are not insubstantial, ascertainment of mortality is likely incomplete.
