Our aim was to investigate the relationship between Val158Met polymorphisms, headache, and pressure hypersensitivity in children with chronic tension-type headache (CTTH). A case-control study with blinded assessor was conducted. Seventy children with CTTH associated with pericranial tenderness and
The catechol-O-methyltransferase (COMT) gene contains a functional polymorphism, Val158Met, that has been found to influence human pain perception, and one study has found that migraine was less likely among those with the Val/Val polymorphism. In the 1995-97 Nord-Trøndelag Health (HUNT) Study, the
The aims of this study were: (1) to investigate the association between the rs4680 Val158Met polymorphism in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH); and (2) to analyze the association between the rs4680 Val158Met polymorphism with UNASSIGNED
To analyze the association between the rs4680 catechol-O-methyltransferase Val158Met polymorphism and to determine the association of this polymorphism with clinical, psychological, and pain sensitivity variables in women with episodic or chronic migraine.

BACKGROUND
Recent genetic association studies have investigated the possible genetic role of the dopaminergic system in migraine. Catechol-O-methyltransferase (COMT) is an enzyme that plays a crucial role in the metabolism of dopamine and its genetic polymorphism is associated with three- to
Genetic variations in the catechol-O-methyltransferase (COMT) gene have been associated with experimental pain and risk of chronic pain development, but no studies have examined genetic predictors of neck pain intensity and other patient characteristics after motor vehicle collision (MVC). We
Liability to spontaneous and experimental pain is genetically determined and there is considerable variability in the antinociceptive effects of drugs commonly used in treating pain conditions and migraine attacks. The causes for variability involve still unknown genetic aspects. Recently, a third
In human studies, low COMT (catechol-O-methyltransferase) activity has been associated with increased sensitivity to acute clinical preoperative or postoperative pain. We explored the association between the COMT genotype and three chronic pain conditions: migrainous headache, fibromyalgia, or
In animals, different types of COMT inhibitors, irrespective of their brain penetration, are pro-nociceptive in several models of acute and inflammatory pain. Similarly, COMT knock-out mice are more sensitive to nociceptive stimuli, whereas in mice over-expressing a high activity COMT variant
Migraine is a common, disabling headache disorder, which is influenced by multiple genes and environmental triggers. After puberty, the prevalence of migraine in women is three times higher than in men and >50% of females suffering from migraine report a menstrual association, suggesting hormonal
PF-06649751 is a novel, oral, non-catechol-based, D1/D5 dopamine receptor partial agonist under investigation for the treatment of motor symptoms associated with Parkinson's disease.A 15-week, phase II, double-blind, placebo-controlled clinical trial was BACKGROUND
Benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP) are synthetic phenylpiperazine analogues. BZP was investigated as a potential antidepressant in the early 1970s but was found unsuitable for this purpose. More recently, BZP and TFMPP have been used as substitutes for
Willow bark (Salicis cortex) is a herbal medicinal drug used to treat fever and pain, such as headaches and lower back pain. Until now, it has not been fully understood which compounds are responsible for the efficacy of the drug.Although salicylic acid is OBJECTIVE
To review literature relevant to a possible prediction of stimulant side effects in attention deficit hyperactivity disorder (ADHD), with implications for guidelines.
METHODS
Recent literature on inverted-U effects of dopamine in the prefrontal cortex (PFC), default mode processing, and
