Do antidepressants cause dyslexia or make it worse ?

Hard to say: Anti-depressants do enter the brain tissue and effect the messages between cells. If a person finds they think less clearly on an anti-depressant, that can certainly be a recognized side effect. I am not aware that it turns someone with normal word decoding skills into one with dyslexia. However, any decline in processing speed on the drug could aggravate an existing learning problem.
