Sferics are low frequency, low intensity electromagnetic pulses radiating from distant meteorological events and other yet unknown sources. It has been hypothesized that sferics are part of the purported sensitivity to weather changes reported by headache sufferers. We tested this proposal. Patients (migraine and/or tension headache) enrolled in a randomized clinical trial gave daily headache data (intensity, frequency, duration of headache) for at least 18 weeks. Concurrently, a sferics measurement station in the vicinity of the patients recorded frequency and intensity of sferics. Usable headache data from 21 patients and the corresponding sferics series were subjected to time series analysis applying ARIMA models and then cross-correlated. We found significant and consistent cross-correlations of moderate size at lag 0 in one patient between ARIMA-filtered headache intensity and frequency (r = 0.18) and amplitude of sferics (r = 0.20). We conclude that in an unselected sample of headache patients some may indeed be susceptible to the low intensity type of electromagnetic radiation exemplified by sferics pulses. This phenomenon warrants further scrutiny.

Background: Treatment acceptance and motivation for psychotherapy of somatizing patients in the general hospital is low. Methods: Patients (n = 91) fulfilling the criteria for somatization were randomized into an intervention group (n = 49) and a control group (n = 42). The patients in the intervention group attended 5 psychotherapeutic sessions based on the modified reattribution model. The patients in the control group received psychoeducational reading material. The primary outcomes were motivation for psychotherapy and contacting a psychotherapist after discharge. The secondary outcomes consisted of changes regarding somatoform symptoms, emotional distress and quality of life. Results: Patients from the intervention group were significantly more motivated for psychotherapy (p = 0.001) than patients from the control group. At the 3-month follow-up, 42% of the patients from the intervention group had contacted a psychotherapist, compared to 20% of the patients from the control group (p = 0.045). At the 6-month follow-up, however, the ratio of patients having contacted a psychotherapist had changed to 44 and 29%, respectively, and was no longer significant. The intensity of somatoform symptoms and the anxiety symptoms decreased and mental functioning improved significantly over time for patients from both groups. Conclusions: Short-term psychotherapeutic interventions for somatizing patients in general hospitals have a moderately better effect on motivation for psychotherapy and contacting a psychotherapist than psychoeducational reading material alone. Future studies should attempt to prove the effectiveness of short-term psychoeducational interventions for somatizing patients in the general hospital.
