June 16, 2009 -- Women may be more likely than men to have "nontraditional" stroke symptoms, especially disorientation, confusion, or loss of consciousness, according to a new study.
The University of Michigan's Lynda Lisabeth, PhD, and colleagues studied 470 people who were treated at the University of Michigan Hospital for ischemic (clot-related) stroke or TIA (transient ischemic attack). They didn't study people who had hemorrhagic (bleeding) strokes.
Most strokes are ischemic. In an ischemic stroke, a blood clot interrupts the blood supply to part of the brain. A similar thing happens in a TIA; the symptoms of TIA are similar to a stroke, but they don't last. TIAs are often called "mini strokes."
