Neurofeedback Side Effects, Adverse Reactions, & Dangers

“While neurofeedback is generally recognized as a safe intervention for improving electroneurological flexibility, some people report side effects.  A majority of reported side effects aren’t considered dangerous and usually transitory in that they’ll eventually subside.  That said, if you aren’t working with a skilled professional, haven’t gotten a QEEG assessment, and/or are conducting neurofeedback on your own – you may increase the risk of experiencing side effects.”

  1. MY NAME IS ZYDIS. back in may and june i started with neurofeedback for anxiety and depression. at the same time that i took 14 treatments up until july, my daughter had been pregnant with triplets and lost them all. my depression and anxiety has gotten so much worse. i was wondering could the lens still be pushing anxiety and depression to worsen. week by week seems worse. i was doing so much better before the lens only trying to get rid of a little bit and i mean little bit of depression that was hanging around. i later found out if you have underlying depression it can make it worse. i called the company they didn’t feel it was still pushing and could be the triplet experience. all i know is it is getting rough and i don’t know which way to turn now. never have i wanted to do meds. thankyou

    • We are not clinicians so I can not give clinical advice. If you do not feel comfortable with the clinician you are working with look for another. A responsible trainer doing neurofeedback would first do a qEEG to look at the brain before trainer to guide the actual training process. There are therapists that do neurofeedback as well and that may be more appropriate than someone just doing neurofeedback. Check on or

    • We can not vouch for LENS Neurofeedback. We are not clinicians here. IF you are not having success with LENS neurofeedback I would suggest seeking a traditional neurofeedback provider. AS far as I know there have been no clinical publications regarding use of the LENS device.

    • Hello Zydis, I have experienced the same reaction but mine only after 5 treatments. Have you gotten any further information that can help? I have been visiting doctors to try to figure this out and it’s been getting very very difficult.

  2. I am experiencing a noticable spike in my depression after the first treatment, accompanied by headache. Is this expected to go away or could it possibly worsen depression in some people?
