In 1995, when she was 84 years old, my grandmother had a mild stroke. She was in the hospital for awhile, and while she was never as strong as she had been before, she soon went back to living on her own in an apartment downtown, where she remained nearly until she died more than six years later.
Four years before my grandmother's stroke, Ontario writer and editor Ruthanne Urquhart had a much more severe one. She was much younger, and she wrote eloquently about it, then posted it to the Web.
Ruthanne's chronicle helps me better understand something of what my grandmother experienced. Be prepared to spend some time reading, since you're unlikely to stop till you finish.
