Hi Judy,
I don't think AD patients all suffer from sinus problems. My husband and I often have sinus headache and congestion, and we only take decongestants. For me, I also take Flonade (inhale from the nose) chronically because I have difficulty getting the congestion out. We are in the age of 50. So it is a common condition for some people with sinus problem, allergy or not.

Your Mom would not need antibiotics unless it is really from the bacteria or a bad cold that has infection. If it is about chronic congestion, antibiotics is not going to help in the long run.

I am sure the fact that she has AD does not help this sinus problem. Did her doctor try to give her some decongestant or flonade and etc? Maybe you can ask him to recommend some specialist about this sinus problem.

My father-in-law who has severe Alzheimers does not have sinus problem, but he has a little running nose after he comes in from the cold air or after his caregiver washes his hair sometimes. The other factor you may want to consider is, since these patients don't really know how to dress up warmly or don't want to dress up properly like normal people, they may catch cold easily.

Take care,

Nina

I don't have AD yet (age 63), but my mother did. She had chronic sinus problems even before the alzheimer's. She was never given antibiotics, but I sure am. I can tell when I have an infection rather than just congestion by the brain fog and inflamation that come with infection. I had to go through allergy tests,  sinus X-rays... before I finally found an allergist who said that even though I didn't have a fever my symptoms sounded like an infection. He prescribed an antibiotic and I got my life back. I wouldn't be at all surprised if "they" don't someday find a connection between AD and sinus infections.
