Purpose of review Sarcoidosis is a complex disease with many faces, and the clinical manifestation and course of neurosarcoidosis are particularly variable. Although neurosarcoidosis occurs in up to 10% of sarcoidosis patients, it can lead to significant morbidity and some mortality. Recent findings Three criteria are usually required for a diagnosis of (neuro)sarcoidosis: clinical and radiologic manifestations, noncaseating granulomas, and no evidence of alternative disease. Recent guidelines have helped to clarify criteria for diagnosing neurosarcoidosis. No firm guidelines exist on whether, when, and how treatment should be started. Treatment depends on the presentation and distribution, extensiveness, and severity of neurosarcoidosis. As regards evidence-based treatment, only a few randomized controlled trials have been done. Hence, several aspects of (neuro)sarcoidosis management are not fully addressed by the current literature. Summary Significant advances have been made in the potential and accuracy of diagnostics for neurosarcoidosis. Treatment should be approached within the context of the patient's anticipated clinical course, avoidance of adverse drug effects, and, if necessary, from the perspective of the comprehensive management of a chronic disease. A multidisciplinary approach to the management of sarcoidosis is strongly recommended.

Purpose The clinical manifestations of sarcoidosis vary widely, depending on the intensity of the inflammation and the organ systems affected. Hence, sarcoidosis patients may suffer from a great variety of symptoms. The aim of this study was to compare the self-reported burden of sarcoidosis patients in Denmark, Germany and the Netherlands, especially the prevalence of fatigue and small fiber neuropathy (SFN)-related symptoms, as well as differences in treatment strategies. Methods A cross-sectional web-based anonymous survey about complaints was conducted among sarcoidosis patients. Patients were invited to take part through the sarcoidosis patient societies as well as through outpatient sarcoidosis clinics in these countries. Results The questionnaire was completed by 1072 sarcoidosis patients (152 Danish, 532 German and 388 Dutch). Almost all patients reported having sarcoidosis-associated symptoms (organ-related as well as non-specific, non-organ related). Fatigue was reported by almost all respondents (90%), followed by pulmonary symptoms (72.4%). More than 50% of the respondents were being treated with prednisone, which was comparable in all three countries. In contrast, second- and third-line treatment differed substantially between Denmark, Germany and the Netherlands. Conclusion Sarcoidosis patients in Denmark, Germany and the Netherlands present with similar self-reported symptoms, organ-related as well as non-specific, non-organ related. Fatigue (90%) and symptoms associated with SFN (86%) were highly prevalent in all three countries.
