And epileptic. Most people don’t understand or suspect the import of that. When you have a petit mal seizure your train of thought is interrupted and may be hard to restore. You may have amnesia for an hour or a day. A grand mal seizure may make you mentally useless for more than a day and will certainly give you a disabling headach for a day, not terribly long for the rest of us but dangerous for a President. As an epileptic she is most likely on Dilantin to control the seizures and will gradually lose her will power and may lose parts of language thus mimicking Alzheimer’s. One can recover from these things sometimes if the nerves heal themselves- it is slow. I did, but it was 10+ years with the concrete block on my head followed by several more years of gradual mental recovery.
