5-hydroxytryptophan has been researched along with Amentia in 4 studies
5-Hydroxytryptophan: The immediate precursor in the biosynthesis of SEROTONIN from tryptophan. It is used as an antiepileptic and antidepressant.

| "Serotonin (5-HT), its precursor 5-hydroxytryptophan (5-HTP), and its major metabolite 5-hydroxyindoleacetic acid (5-HIAA) were measured in the cerebrospinal fluid (CSF) of 14 patients with dementia of the Alzheimer type (DAT) and in nine controls by high-performance liquid chromatography with a novel multisensor coulometric detection system." | 7.67 | Serotoninergic system in dementia of the Alzheimer type.

| "Twenty-four senile dementia patients in the age range 65-85 years were subjected to a new sensitive tryptophan loading test: Dopa-Tryptophan loading ("Dop-Try loading") in order to determine whether Try malabsorption occurs in senile dementia and if so how frequent this is." | 7.66 | Tryptophan malabsorption in dementia. Improvement in certain cases after tryptophan therapy as indicated by mental behaviour and blood analysis. ( Lehmann, J; Persson, S; Wålinder, J; Wallin, L, 1981) |
