Ten women with recurrent migraine-like headache, flush, urticaria and itching excoriations were put on a protein/tryptophan reduced diet. The 5-HT uptake kinetics in platelets, the frequency of headache attacks and skin symptoms were recorded. On customary food the 5-HT uptake kinetics were severely
Headache is one of the main complaints in pediatric neurology. Exogenous melatonin has been shown to be useful and safe in improving sleep-wake cycles and sleep quality in children. Tryptophan as well plays a key role in sleep regulation. So far, no studies tried to analyze the effects The pathogenesis of migraine as well as cluster headache (CH) is yet a debated question. In this review, we discuss the possible role of the of tyrosine and tryptophan metabolism in the pathogenesis of these primary headaches. These include the abnormalities in the synthesis of neurotransmitters:
Sensitivity to light was investigated 5 and 8 h after consumption of an amino acid drink which contained L-tryptophan (balanced amino acid condition: 19 controls and 22 migraine sufferers) or which produced a short-term reduction in brain serotonin synthesis by omitting L-tryptophan (tryptophan
OBJECTIVE
We investigated whether tryptophan hydroxylase 2 (TPH2) gene polymorphisms were involved in the aggravation of migraines due to the overuse of medication.
METHODS
Forty-seven migraine patients (6 males and 41 females; 36.4 10.3 years) and 22 MOH patients (1 male and 21 females; 39.6 9.9
Monoamines are involved in the central nervous assimilation and modulation of the pain flow. According to a personal hypothesis, a disorder of this biochemical control (in particular a precariousness of brain 5-hydroxytryptamine turnover), is the basic mechanism of some painful conditions, such as
1 The psychotropic effects of a single oral dose of (--)-tryptophan (5 g) in human volunteers were investigated using a series of physiological and psychological tests. 2 Self-ratings of mood showed increase in drowsiness but no euphoria was detected. 3 Severe initial nausea occurred and headache
The blood levels of free tryptophan, glucose and insulin were determined in different groups of patients suffering from headache, initially and after a glucose tolerance and a tolbutamide tolerance test. The control group consisted of subjects without neurological or psychiatric disturbance. A sharp
Bipolar disorder (BD) and cluster headache (CH) are distinct conditions with important similarities such as a temporal pattern of disturbances, dysregulation of the sleep-wake cycle, and response to lithium treatment in a proportion of patients. Aiming to identify common transcription signatures in
5-Hydroxytryptophan (5-HTP) is the precursor of the neurotransmitter serotonin and has been used for the treatment of various diseases such as depression, insomnia, chronic headaches, and binge eating associated obesity. The production of 5-HTP had been achieved in our previous report, by the
