Also see compulsive, intrusive memory, obsessive, self-downing.

SAD - see Seasonal Affective Disorder or Social Anxiety Disorder.

Safe Zone - any area within which anxiety symptoms are not notably aggravated. Also see agoraphobia, separation anxiety.

Seizure - a sudden attack of epilepsy that produces convulsions. Seizures are typically classified as 'partial' or 'generalized'. Partial seizures include "simple partial seizures" (motor, sensory, autonomic) and "complex partial seizures" (absences, complex hallucinations, affective symptoms, automatism). Generalized seizures are characterized by absence attacks (petit mal), tonic-clonic (grand mal), bilateral myoclonic, drop attacks (akinetic). It is interesting to note that the auras associated with some seizures are remarkably similar to, if not the same as, some forms of anxiety attacks. Consequently, panic attacks are sometimes described as sub-epileptic seizures. Also see temporal lobe seizure.

Serotonin and Norepinephrine Re-uptake Inhibitor (SNRI) - any medication that slows the re-uptake of serotonin and norepinephrine by neurons in the brain, thus allowing serotonin and norepinephrine to remain in the synapse longer. Like most psychiatric medications, SNRIs are best started with ramped dosage. The SNRI medications include (generic names) duloxetine, venlafaxine. Also see antidepressant, re-uptake inhibitor, serotonin re-uptake inhibitor.

SRIs can interfere with sexual desire or function, but this effect is often temporary. Like most psychiatric medications, SRIs are best started with ramped dosage. The SRI medications include (generic names) buspirone hydrochloride, fluoxetine, fluvoxamine, mirtazapine, nefazodone, paroxetine, sertraline, trazodone. CAUTION: SRIs should not be combined with MAOIs. SRIs may pose risks to unborn children during pregnancy and newborns through breast milk. A possible relationship between SRIs and suicidal ideation remains controversial. Nefazodone has been discontinued due to association with liver damage. Also see anorgasmia, antidepressant, re-uptake inhibitor, serotonin and norepinephrine re-uptake inhibitor.

Serotonin Syndrome - a disorder caused by excessive serotonin levels. Symptoms can include restlessness, hallucinations, loss of coordination, fast heart beat, rapid changes in blood pressure, increased body temperature, overactive reflexes, nausea, vomiting and diarrhea. Possible causes include migraine headache medications known as triptans, antidepressants (especially SRI and SNRI medications) and any other substance (natural or pharmaceutical) which elevates serotonin. Contrast with serotonin deficiency syndrome.
