DEAR ABBY: Is it possible to lose your sense of humor because of a stroke? Before it happened, my dear sister was witty, fun-loving and the life of the party. She has recovered physically, but she no longer has a sense of humor. Everything is deadly serious to her now, and she doesn't understand when someone is making a joke. I want her to "lighten up," but I'm afraid this might be a result of her brain injury. Any insight? -- LAUGHING BY MYSELF
DEAR LAUGHING: What you have described could absolutely be related to your sister's stroke. When it happened, certain areas of her brain were "disconnected." This isn't her fault, and telling her to "lighten up" will not improve the situation. Thank your higher power that she has recovered physically, keep your comments direct and literal, limit the jokes and you will both be more comfortable.
