Loss of sleep, glymphatic system
I have developed insomnia after a long term use of psych meds and rtms. When I used to take meds, sleep was okay. But earlier, when I started psychiatric medicines, sleep loss/insomnia was never there. I didn't have any insomnia. Now, after 5+ years, i haven't been able to sleep for long. Feeling memory issues, brain fog , and other breathing issues as well. Wanted to ask if accumulation of metabolic waste accumulates over time can clear after one regains sleep with the help of psychiatric medicines. Can the glymphatic system clear waste over time and hope there is no neuronal damage? A young person. Please guide right. Or there may be loss of brain cells? Please guide correctly.

I want to acknowledge how much courage it takes to voice these struggles. Often, we treat mental health as a matter of 'willpower,' but as a psychiatrist, I can tell you that what you are experiencing has a real biological and neurological basis.
Your brain, like any other organ, can sometimes struggle to maintain balance under stress. Seeking treatment isn't a sign of failure; it’s a proactive medical decision to regain your quality of life. We can work together to understand the 'why' behind these feelings and find a structured path back to your baseline. You don't have to navigate this alone.

I can sense a lot of anxiety in your questions. A little bit more history is needed like what was the OG diagnosis for which treatment was given. What medications were used. But to answer your main query all medications have something called as a half life.. ie within a certain period of time half of medication is excreted out of body.. and after that another half portion, another half.. Within 4-5 half lives all of the medication is out of the body. Now this time period could be hours to days.. But no medications stay in the body for years even after years of use. If it were so we would have loaded the patient with medicine one time and he would be good to go for years. It doesn't happen right?
Coming to neuronal damage.. Again I need to know the medications' name to comment.
But generally unless it's alcohol or drugs(abusive ones), there isn't any brain damage reported by use of regular psych medicines. Yes there is some change in brain chemistry but we need more info to discuss that specifically. Hope this helps. Reach out for more information. Have a good day

I want to reassure you: chronic insomnia can cause brain fog, memory issues, and fatigue, but these are usually functional and reversible, not permanent neuronal damage—especially in a young person. The glymphatic system, which clears metabolic waste during deep sleep, resumes functioning once restorative sleep improves. There’s no strong evidence that long-term insomnia alone causes irreversible brain toxicity. However, prolonged stress, anxiety, medication changes, or rTMS effects may disturb sleep architecture. The priority is structured sleep restoration—optimizing medications, CBT-I, circadian regulation, and ruling out breathing issues like sleep apnea. With proper management, cognitive clarity typically improves over time.
