Depression is repeatedly linked to changes in BDNF and neurogenesis, so you would probably just see greater neurodegeneration compared to healthy controls anyway. Post-marketing surveillance is hard to draw any causal conclusions from...

Trazodone is also used for sleep.

I think much more widely for sleep than depression.... it was originally an anti-depressent but had a nasty side-effect of making one very sleepy.

Trazodone helps me for sleep, it's incredible. I'm out like a light and it's not addictive. If you have nighttime anxiety and stress-related sleep issues, it can be a godsend.

I have heard that it is addictive so I'm curious as to what your experience is when not taking it. No withdrawal symptoms at all?

Nope, zero addiction. I take it about 5x a week, generally have weekends off.

also used for anger issues

It's interesting to see a sleep drug that might prevent Alzheimer's. I recently found out that benedryl might cause it.

That's why you compare against SSRIs
