| After a long battle with depression, this is how I interpret the phenomenon that "boosting" serotonin levels does not work. SSRI's do not increase the pool of available serotonin, they just artificially increase the amount that remains in the synaptic cleft, facilitating additional firing of the neuron (or for a longer duration, I'm not sure which). They do not increase a neuron's ability to synthesize serotonin and release it into the synaptic cleft at the appropriate time. SSRI's cause our neurons to reuse serotonin longer than they normally would, which is not how we evolved to use serotonin. The way this felt to me as a human interacting with the world around me was artificial happiness and artificial feelings of ease. I felt "better", but it didn't feel like it was grounded in anything real. I felt happy when happy things happened, but I also felt happy when sad things happened. Eventually it wore off and SSRI's no longer had any effect on me. I eventually tried tryptophan and B vitamins (specifically B6), which our bodies use to synthesize serotonin. I got a similar effect to when I first started SSRI's, but it felt real. I was able to be happy when something happy happened. But when something sad happened I also felt sad. This effect has endured for 4 years now. I have since found that I had a serious problem with a particular toxin which poisons many of the pathways involved with serotonin synthesis (among many many others including one of the most fundamental, the Citrate Cycle). A way around the poisoning is large doses of the appropriate nutrients. This is because the toxicity causes serious inefficiencies in their use by the body's biochemical pathways. This was my personal experience. Depression is caused by many factors and I'm sure what works for me would not work for many. It can be genetic issues, other kinds of toxins, and overwhelming amount of trauma, chronic infections, unhealthy relationships, etc. Or a combination of those. |
