Hoping this is a proper section for this discussion. If you have/had OCD and have taken a SSRI or SNRI i'd love to get your input. Others are obviously more then welcome to chime in as well. My question is, do SSRI's have any permanent effects on brain structure? Obviously they help regulate the re-uptake of Serotonin/ or Norepinephrine(for SNRIs) and therefore increase the amount of that neurotransmitter in the synapse. Do taking these drugs have any permanent effects on the changes in brain composition they create? I'd also would like to hear about any changes in productivity/learning capability you experienced with these drugs.
