Could Alopecia Areata Evolve to Totalis or DUPA?

I have been recently diagnosed with alopecia areata (one spot) and have had several HT session in the past. Recently been under a lot of work related stress. and my hair has been thinning all over event in the safe zone (I am 48 Years old). And the back of my scalp has a see thru appearance. So I am wondering if this is diffuse alopecia areata that could evolve to alopecia totalis or DUPA since my donor area is very thin?

Anything is possible, but not probable. Alopecia areata without any treatment often will resolve over time (which can take up to one year).
