WHOLE PSYCHIATRY

NEUROTRANSMITTER	TYPE	DERVIVED FROM	CLINICAL RELEVANCE
GABA	Amino acid	Glutamate	The most ubiquitous. Involved in sleep, anxiety reduction, muscle relaxation. Involved in relaxing effects of alcohol.
L-tryptophan (L-T)	Amino acid	Can only be obtained in the diet.	Promotes sleep, especially when taken with a high carbohydate, low protien meal. Dangerous when consumed with MAO antidepressants.
Tyramine (Tyr)	Amino acid	Fats and carbohydates	Dangerous when consumed with MAO antidepressants.
Glutamate (Glu)	Amino acid	Fats and carbohydates	MSG reaction to Chinese food. The major excitatory amino acid. May be associated with neurotoxic effect in alcoholism.
Dopamine (DA)	Biogenic amine	Tyrosine, fats, and carbohydates	Mania, schizophrenia, Parkinson's diease, attention deficit disorder, substance abuse, tics, blood pressure regulation. Antipsychotics (major tranquilizers) inhibit DA action. Some antidepessants act here.
Norepinephrine (NE)	Biogenic amine	Dopamine	Depression, anxiety, panic, blood pressure regulation. Necessary for learning and memory.
Serotonin (5-HT)	Biogenic amine	L-tryptophan	Depression, mania, anxiety, blood pressure and temerature regulation. Many antidepressants, new antipsychotics, and nonadicting antianxiety agents act on these conditions via this neurotransmitter.
