Recommendations for using fluorodeoxyglucose positron emission tomography (FDG-PET) to support the diagnosis of dementing neurodegenerative disorders are sparse and poorly structured. ⋯ Despite limited formal evidence, panellists deemed FDG-PET useful in the early and differential diagnosis of the main neurodegenerative disorders, and semi-automated assessment helpful to assist visual reading. These decisions are proposed as interim recommendations.

Medication-overuse headache (MOH) is a chronic headache (≥15 days/month) associated with overuse of acute headache medication. The objective was to investigate headache-related disability before and after self-detoxification from MOH in the general population, as well as possible predictors for successful outcome. ⋯ Medication-overuse headache causes substantial disability in the general population. Self-detoxification leads to reduced headache frequency and disability, although 24% of the participants did not complete self-detoxification. Detoxification should be offered to MOH patients as early as possible with a focus on headache frequency, disability and psychological distress.

Randomized Controlled Trial Multicenter Study
Early management of patients with medication-overuse headache: results from a multicentre clinical study.
Educational intervention has proved to be effective in reducing drug abuse in uncomplicated medication-overuse headache (MOH). This ancillary of the SAMOHA multicentre study aimed to assess any differences in phenotypic characteristics, type and amount of drugs overused, and comorbidities between patients with MOH who responded to simple advice and those who did not. ⋯ Our findings suggest that in MOH trials, after an educational session, an observational period is needed in order to confirm the diagnosis of MOH and to avoid overestimation of the effect of other treatments used to manage MOH. Future research should focus mainly on those patients with MOH who do not respond to simple advice and with unsuccessful withdrawal.

An external validation of the selection criteria of diffusion-weighted imaging or computerized tomography perfusion assessment with clinical mismatch in the triage of wake-up and late-presenting strokes undergoing the Neurointervention with Trevo (DAWN) and the Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke (DEFUSE3) trials was conducted in a cohort of unknown onset stroke (UOS) patients treated with thrombectomy. ⋯ The results of the DAWN and DEFUSE 3 trials were externally validated in a UOS cohort where the trials' selection criteria identified a similar proportion of responders to thrombectomy.

Impaired bulbar functions of speech and swallowing are among the most serious consequences of amyotrophic lateral sclerosis (ALS). Despite this, clinical trials in ALS have rarely emphasized bulbar function as an endpoint. The rater-administered Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) or various quality-of-life measures are commonly used to measure symptomatic benefit. Accordingly, we sought to evaluate the utility of measures specific to bulbar function in ALS. ⋯ Based on these findings and its relative ease of administration, we conclude that the CNS-BFS is a useful metric for assessing bulbar function in patients with ALS.
