1. What are the side effects of the SSRI's? What pathways in the CNS explain why they occur (see red highlighted information below)?

I have found an excellent fact sheet with this information, which addresses the side effects and the pathways very thoroughly. It has empirical evidence for each of the side effects with the articles linked for easy access at the end. Indeed this is an excellent resource. It also has the side effect for the SSNRIs. I hope this helps and take care.
SSRI & SSNRI Antidepressants Side Effects
"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 antidepressants (and even Ritalin) may interact (primary or secondary) with the serotonergic (or serotoninergic) system in the brain. Every medication -especially SSRI antidepressants- boosting serotonin activity in the brain, has potential to induce the very dangerous and potentially fatal hyperserotonergic state of the Serotonin Syndrome.

1. 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)
2. 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).

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...
