((( The Practical Seer )))

[Don Genardo Sacateca]

"Are Your Chemicals out of Balance?Perhaps the most frequently cited evidence in support of the chemical imbalance hypothesis is the effectiveness of antidepressants, 
many of which increase the amounts of serotonin and other neurotransmitters at synapses. 
Zoloft, Prozac and similar selective serotonin reuptake inhibitors (SSRIs) result in such an increase and can often relieve depression, at least when it is severe. 
As a result, many believe that a deficiency in serotonin and other neurotransmitters causes the disorder. 
But just because a drug reduces symptoms of a disease does not mean that those symptoms were caused by a chemical problem the drug corrects. 
Aspirin alleviates headaches, but headaches are not caused by a deficiency of aspirin."
