What Are The Symptoms And Treatment For Stroke?

I found out yesterday (Sunday), that on Saturday my husband had no recollection of cutting down some trees with a chainsaw in the backyard even though he had just finished doing it. He sat on the fresh cut logs and told his buddy that these logs must have been just recently cut because they looked fresh. The buddy thought he was joking and realized later he wasn't. He also doesn't remember other events of the evening which included a cookout with our friends etc. He told me on Sunday about a headache he had as well. Could this have been a mini stroke?
