A friend two years ago read an online article that claims antidepressants cause brain damage. I don't know which one, but I imagine it was something like this.
Do antidepressants cause brain damage?
The article you refer to seems biased and misleading. It quotes multiple serious-looking papers, then reaches a conclusion not mentioned in any of them.
Several articles (e.g. this and this) claim that anti-depressants are not so efficient in curing depression - after you stop taking them, depression often returns.
One article reports a correlation between depression and later dementia. It doesn't mention anti-depressants.
The nearest thing to brain damage I could find is claims that anti-depressants cause the body to build tolerance, so after you stop using them the depression may be worse than before.
Anti-depressants are medications targeting neurotransmitters in the brain. They don´t cause brain damage, quite opposite, they help the brain restore its function after damage, as occurs in stroke (escitalopram enhances cognition after stroke)
