Previous functional imaging studies in episodic cluster headache (CH) patients revealed altered brain metabolism concentrated on the central descending pain control system. However, it remains unclear whether changes in brain metabolism during the “in bout” period are due to structural changes and whether these structural changes vary between the “in bout” and “out of bout” periods. To quantify brain...
Episodic migraine (EM) may evolve into the more disabling chronic migraine (CM, monthly migraine days⩾8 and headache days⩾15) with unknown mechanism. Aiming to elucidate the pathophysiology of CM and its relationship with EM, this study characterized the visual cortical responses in CM and EM. Neuromagnetic visual-evoked responses to left-hemifield checkerboard reversals were obtained in patients...
Medication overuse is relatively common in patients with frequent headache. To explore the prevalence of patients who meet the criteria for substance dependence in Diagnostic and Statistical Manual of Mental Disorders, Edition IV (DSM-IV), and to identify variables of substance dependence among patients with chronic daily headache, we recruited consecutive patients with chronic daily headache at a...
This paper presents the results of health-related quality of life (HRQoL) in 901 patients consecutively visiting a headache clinic of a national medical center in Taipei, Taiwan. HRQoL was evaluated with the Medical Outcome Study-Short Form (SF-36) and the Hospital Anxiety and Depression Scale (HADS). According to the classification criteria for chronic daily headache (CDH) proposed by Silberstein...
The comorbidity of headache and depression is rarely studied in the elderly. Confounders were seldom controlled in previous studies. From August 1993 to March 1994, we conducted a door-to-door survey to investigate the relationship of headache and depression in a Chinese elderly population (age≥65 years old) in two townships of Kinmen, Taiwan. A total of 1421 participants (71%) out of 2003 eligible...
