Is the serotonin transporter gene polymorphism associated with the susceptibility and the pain severity in idiopathic trigeminal neuralgia patients?
The 5-HTTLPR polymorphism is associated with the susceptibility to TN and pain severity of TN.
The present study could not confirm hypotheses that the antinociceptive effects of DSB are related to changes in breathing frequency, heart rate variability, or hypoventilation/hyperventilation when applied as a short-term intervention. It could confirm the notion that increased cardiac parasympathetic activity is associated with reduced pain perception.
