Frontotemporal Dementia Progression?

Would anyone be willing to briefly share with me the progression of your loved one’s FTD? My husband was diagnosed last month after he finally agreed to go to the doctor. We had been seeing signs for months. Mostly aphasia, some irritability (not violent), forgetting conversations, inability to do basic math skills at times.

Sometimes, he seems so normal. But a lot of the time he’s withdrawn and not normal. I second guess it a lot.
