Quality of life in headache patients with analgesic overuse and therapy efficiency
Trigeminal somatosensory evoked potentials (TSEPs), thyroid-stimulating hormone (TSH) and quality of life (QoL) were studied in 123 migraine patients and 10 healthy subjects. Latency of P1 as well as asymmetries of P1 latency and N1P1 amplitude were enlarged in migraine patients. Lower levels of TSH in migraine patients correlated with more pronounced asymmetries in TSEPs and poor QoL. Conclusion: TSH levels may play role in modulation of trigeminal system in migraine.
