So now, do people with Parkinson's disease score very high on Acetylcholine and very low on Dopamine?
I didn't think so.
Making these broad strokes of characterizing personality by neurotransmitter probably only yields positive results in supplementation because the brain adapts to the supplements, much like any other psychiatric medication. However, if somebody has a pathology; and this can arguably be stated about people with mental health issues that are pervasive developmental or characterized (in name) as "personality" disorders; well, trying to go this route would yield very little.
Aside from the fact that this appears to be simply a step up from asking a psychic to help you align your chi or whatnot, there is the total disregard of receptor subtypes and neurotransmitter pathways. Most of these neurotransmitters do drastically different things in different parts of the brain and/or at different receptor subtypes.
I don't know anyone with Parkinsons and thus cannot evaluate your claims about Braverman capturing the dopamine deficiency in Parkinsons patients. The questions do ask about things such as tremor, motivation and physical coordination. There are no psychics or spiritualists involved in all this. You buy the book, you read it, you're done, you can use it for the rest of your life. I have given the Braverman tests to some people and their brain chemistry is fine. They don't need to even take anything! Though some have told me that at different points in their lives when they were going through crises they would have answered the questions very differently.
I don't really think you can say that SSRIs (Serotonin), Benzos (Gaba), ACH reuptake inhibitors (Choline) and Dopamine increasing drugs like Deprenyl are psychologically similar.
I haven't taken any of these (except huperzine which is an ACH reuptake inhibiting supplement) but milder forms of brain chemistry manipulation with the regimens I laid out in the above postings are psychologically different from each other and the difference is fairly real and obvious and IMHO roughly corresponds to the Braverman characterizations and tests. To put it in laymans terms... Most would agree that the effects of chocolate(dopamine), alcohol(Gaba + Serotonin) and Cigarrettes (Choline) are psychologically different from each other even though all can be said to temporarily alleviate depression.
The functional aspect of all this is I regularly take the test when something is "off" and then take the right combination of supplements to put me back on the right track without producing the production of neurotransmitters that are not out of balance. I have been doing this for 3 years now so I have the questions more or less memorized and can quiz myself whenever I feel like it. Of course, over the years, I have learned the normal tendencies of my brain pretty well and have settled into a regular regimen.
This is starting to enter mainstream science. For instance, the article at the economist below:
http://www.economist...ory_id=12415194Serotonin is another neurotransmitter that is usually deficient in an addicted brain. This probably accounts for the depressive side of withdrawal symptoms (serotonin receptors in the brain are the target of antidepressant drugs such as Prozac). Serotonin is made from an amino acid called tryptophan, which is found in foods such as meat, brown rice, nuts, fish and milk. Philip Cowen, a psychiatrist at Oxford University, has found that reducing the amount of tryptophan in someone’s diet increases depressive symptoms and also that increasing it can induce a more optimistic outlook.
Anxiety and sleeplessness are common withdrawal symptoms. They happen because many addictive drugs reduce the supply of a chemical called glutamine, a precursor to GABA. One of GABA’s roles is to promote relaxation. (The molecular receptors for GABA are the target of tranquillisers such as Valium.) But glutamine levels can be restored, and production of GABA boosted, by the consumption of an amino acid called N-acetylcysteine (NAC) that is found in nuts and seeds.
This is not just theory. A controlled study published last year in the American Journal of Psychiatry by Steven LaRowe, of the Medical University of South Carolina, and his colleagues, found that giving NAC to cocaine addicts reduced their desire to use the drug sufficiently for it to be recommended as a treatment. A different study found that NAC reduced the desire to gamble in more than 80% of those addicted to this pastime, compared with 28% of those who were given a placebo.
