I don't think there will be a "magic machine" to diagnose brains that aren't functioning "rationally" and "correctly" -- which I'd like to note many individuals with brain abnormalities are geniuses in other areas i.e. Vaslav Nijinsky (ballet dancer), Ludwig von Beethoven (composer), Winston Churchill (leader), Isac Newton (scientist), Charles Dickens (author), Abraham Lincoln (president) etc.
I believe many artists and poets are able to describe or portray the depths of emotions due to their "malfunctioning" minds.
They know some of the mechanisms of drugs and are able to tell what neurotransmitters they work on (~1960's) i.e. agonists, releasers, precursors, reuptake inhibitors, dopamine, norepinephrine, and serotonin.
I know you stated you don't think a diagnosis test will "ever" be available. Now, I am sure people didn't think electricity or flying was possible either, but I believe science will prevail. My main concern is once what I envision does come into existence, it could cause morality issues -- similar to how genetic sequencing and mapping raised ethical questions. Being able to diagnose a patient should ONLY be used for treatment purposes and to further help a patient. It should not be used to try and classify/label, discriminate, or irrationally "try" to protect others.
Medical breakthroughs may take time and serendipity, but they will occur. Researchers need to be given freedom (within ethics), access to the right tools, and an educational environment that allows innovations to occur.
I know you mentioned neurofeedback; I'll assume you were referring to QEEGs (brain mapping). I also believe micro-dialysis is helping scientists and researchers to better understand the brain.
I know Wikipedia isn't the best source, but here's a brief overview of microdialysis:
"Microdialysis is a minimally-invasive sampling technique that is used for continuous measurement of free, bound analyte concentrations in the extracellular fluid of virtually any tissue. For the procedure to be carried out, small amounts of brains chemical solutions are collected. Analytes may include endogenous molecules (e.g. neurotransmitter, hormones, glucose, etc.) to assess their biochemical functions in the body, or exogenous compounds (e.g. pharmaceuticals) to determine their distribution within the body."
Personalities encompasses plenty of variables, but the primary focus for developing a diagnosis tool should be the genetic, biological, or neurological reason certain people suffer from mental disorders ex. major depression -- regardless of positive or negative environmental factors. I am not talking about individuals who have dire circumstances or extreme environmental factors, that would cause most people to suffer mentally. The focus should be based on the "type-1 diabetics of mental health".
I'd like to note it was in 1977
the A1C test became the gold standard for diagnosing diabetes. Yet, in the 1920's
Eli Lily & Company developed insulin commercially, allowing diabetics live's to be transformed.I want to write blog articles for Huffington Post... Who has connections to send pieces to their editors?!?! Help a gay brother out
