All Truth passes through Three Stages: First, it is Ridiculed. Second, it is Violently Opposed... Third, it is Accepted as being Self-Evident. - Arthur Schopenhauer (1778-1860) By Charly Groenendijk Back to Side-Effects

Toxicity and Brain Damage
"Who does Not Know the Truth, is simply a Fool...
Yet who Knows the Truth and Calls it a Lie, is a Criminal."
- In "Galileo Galilei" by Berthold Brecht (1898-1956)
Take notice that also non SSRI anti-depressants (and even Ritalin) may interact (primary or secondary) with the serotonergic (or serotoninergic) system in the brain.
PHYSICIANS REMEMBER... "FIRST DO NO HARM"...
SSRI/SSNRI-induced Toxicity & Brain Damage by disrupting the balance of Body & Brain Metabolism
SSRI's are "Selective Serotonin Re-Uptake Inhibitors." In contrast to the deceiving claim of the pharmaceutical companies that SSRI's or SSNRI's may correct some sort of "biochemical imbalance" of serotonin in the brain, all of these serotonergic agents actually cause major and dangerous imbalances in the brain and the body, evidenced by the many medical reports (below) of severe toxic neurological and physical side-effects. Neuronal re-uptake of neurotransmitters is metabolism. What serotonin re-uptake inhibitor actually means is that the SSRI-antidepressant interferes with ones ability to metabolise serotonin, so that can and will build up to toxic amounts after prolonged use. In other words, an SSRI-antidepressant impairs the ability of cells to metabolise serotonin, not only in the brain, but -since serotonin is widely distributed throughout the body- in the body as well! The greatest concentration of serotonin, around 90%, is not found in the brain, but is found in the gastrointestinal or digestive tract (human gut, intestines, bowels).
Originally, the neurotransmitter serotonin -thought to be secreted by the Pineal Gland- is called a neurohormone, because of it's specific regulatory effect on the activity of the Endocrine Glands in the human body. (1),(2) Affecting serotonin thus means also affecting the Glandular Endocrine System. Next to it, serotonin affects the Cardiovascular System and the Respiratory System, under which, the lungs. Serotonin is also found in blood platelets and stimulates platelet aggregation (blood clotting). Furthermore, serotonin is known to affect contraction of smooth muscles (such as those of the gut) and blood vessel elasticity (vasoconstriction and expansion). More information: Serotonin & the Pineal Gland
A recent study (25 sept, 2004) shows us clearly that serotonin toxicity can even appear rapidly in a few hours after taking a single therapeutic dose of SSRI medication. In Bio-Psychiatry it is a common thought that SSRI's are believed to have their effect by inhibiting the re-uptake of serotonin (downregulation of transporters) and thereby gradually increasing serotonin outside the tissue cell wall (extracellular) in the synaptic gap between brain cells (neurons) in the brain. In this important study, Zoloft (Lustral, sertraline) was given to monkeys for 4 weeks to establish how long it would take before Zoloft would have it's effect on serotonergic neurons and thus elevation of serotonin. In contrast with the commonly accepted SSRI theory, it was observed that serotonin levels raised NOT gradually, but rapidly and dramatically and kept on raising during these 4 weeks, an effect that can NOT be ascribed solely to a "re-uptake inhibition" of serotonin!
Antidepressant induced neurological and/or physical toxicity (body and/or brain damage) either as a result of prolonged inhibition of P450-2D6 liver-enzymes, or as a result of impairing serotonin metabolism, can take on many forms as described below. A few examples are: Hyperserotonemia, such as the lifethreatening condition the Serotonin Syndrome, Epileptiform Discharges, Epileptic Seizures and/or Epilepsy, Hypoglycaemia/Hyperglycemia (Low/Elevated Blood Sugar Imbalance), Stroke/Hemorrhagic Syndromes, Frontal Lobe Syndrome, Tardive Dyskinesia/Dystonia, Parkinsonism, Akathisia, Mania, etc...
Tardive Dyskinesia/Dystonia, Parkinsonism & Akathisia
SSRI & SSNRI antidepressants induced side-effects (Iatrogenic Extrapyramidal Symptoms) are
recognized to be similar to Neuroleptic (anti-psychotic) induced side-effects. These side-effects are known as Tardive Dyskinesia/Dystonia (severe body movement disorder, mostly permanent), Parkinsonism (a sign of future Parkinson's disease) and Akathisia (a Neurological driven severe mania/agitation that can lead to suicidality, suicide attempts, self-harm & suicide). It is well documented in the medical literature that these neuroleptic induced side-effects refer to damage at dopaminergic neurons in the "motor system" of the
"Basal Ganglia", a structure deep in the "Limbic System" of the brain. 1, 2, 3, 4, http://www.emedicine.com/EMERG/topic338.htm (scroll down)
Serotonin Syndrome
The Serotonin Syndrome is a potentially lethal condition caused by excessive serotonergic activity. It is a very dangerous and a potentially fatal side effect of the serotonergic enhancing drugs such as SSRI & SSNRI antidepressants and is diagnosed by the presence of at least 3 of 10 symptoms: mental status changes (confusion, hypomania), agitation, myoclonus, hyperreflexia, diaphoresis, shivering, tremor, diarrhea, incoordination, and fever. This "hyperserotonergic" toxic condition requires heightened clinical awareness in order to prevent, recognize, and treat the condition promptly. Promptness is vital because, as we just mentioned, the serotonin syndrome can be fatal and death from this side effect can come very rapidly. The Serotonin syndrome is brought on by excessive levels of serotonin and is difficult to distinguish from the "Neuroleptic Malignant Syndrome" because the symptoms are so similar. The "Neuroleptic Malignant Syndrome" is a serious condition brought on by the use of neuroleptic drugs (anti-psychotics).
