Stroke patients are definitely just leaving it far too late to seek treatment. It's been happening in multiple countries. There was even an unfortunate New York Times article where a doctor talked about seeing strokes of a severity they wouldn't expect in people so young, which was spun as proof the coronavirus was causing the strokes - and it just happened to mention in passing that those patients had ignored their symptoms and taken far longer than usual to seek treatment. Of course, if coronavirus was causing strokes we'd expect an increase in stroke patients rather than a decrease.
