Has she been diagnosed with Alz.? I apologize if you stated so, and I may have missed that.

Within recent reports, the onset may commence as many as 10 to 20 years prior to official/clinical diagnosis.

As a leading neuro. doc, who specializes in Dx'ing Alz. and differential Dx'ing -- among neurodegenerative conditions: It's not the analyzing and hindsight that most matters, but obeservation.

If you noticed definitive signs/symptoms (and maybe way before others) don't hesitate to share your observations with the doc/s. They may not be able to comment, but will take all into consideration. (And, that is stated due to a patient's HIPPA, etc.)

Too, whether you hubby should visit or not: That's a personal decision.

There is "staging" that is assigned to Alz. and its progression. The only way to assess that is through a skilled, licensed professional.

On a personal note: If he feels that a visit is over-due, then, maybe it's time. He might find her better off than others are stating.

My up-close and too close understanding is: Folks with Alz. or FTD have both good day and some bad. It's a total roller coaster until end stage.

P.S.: I know there are some typos., but have been up all night cleaing "fingerpaint" of stuff that makes me gag, thanks to caring for someone who is so far outta it.
