Variability of the Autonomic Nervous System (ANS) During Cluster Headache (CH). — AVASNA  

Cluster Headache Clinical Trial

Official title:
AVASNA : Variability of the Autonomic Nervous System (ANS) During Cluster Headache (CH).

Clinical Trial Summary

Cluster Headache (CH) is associated with ipsilateral vegetative signs, related to parasympathetic system hyperactivity and/or signs of sympathetic hypoactivity. The precise mechanism of Cluster Headache (CH) is still unknown. The question is whether these dysautonomic disorders are simply secondary to the Cluster Headache (CH) process or whether they are the triggering factor.

Clinical Trial Description

This study cares about the evolution of the Autonomic Nervous System (ANS) in Cluster Headache (CH) seizures. Patients will be offered Holter ECG to study the temporal relationships between changes in Autonomic Nervous System (ANS) activity during Headache (CH) seizures and changes in Autonomic Nervous System (ANS) activity before and after seizure treatment, using heart rate variability measurement. The hypothesis is that there would be an initial temporary sympathetic activation, followed quickly by parasympathetic hyperactivation and a return to a state of equilibrium. ;
