Headache research has been a productive area, and understanding of primary headache pathophysiology has increased greatly. There are many more questions that need to be answered to gain a better understanding of the primary headache process. For the clinician,there is value in understanding the pathophysiology of primary headache, because this understanding can help improve diagnostic acumen and shape treatment plans to provide patients with more effective treatment.

Intranasal oxytocin for apathy in people with frontotemporal dementia (FOXY): a multicentre, randomised, double-blind, placebo-controlled, adaptive, crossover, phase 2a/2b superiority trial.

Background: No treatments exist for apathy in people with frontotemporal dementia. Previously, in a randomised double-blind, placebo-controlled, dose-finding study, intranasal oxytocin administration in people with frontotemporal dementia improved apathy ratings on the Neuropsychiatric Inventory over 1 week and, in a randomised, double-blind, placebo-controlled, crossover study, a single dose of 72 IU oxytocin increased blood-oxygen-level-dependent signal in limbic brain regions. We aimed to determine whether longer treatment with oxytocin improves apathy in people with frontotemporal dementia.

Background: Given burdensome side-effects and long latency for efficacy with conventional agents, there is a continued need for generalised myasthenia gravis treatments that are safe and provide consistently sustained, long-term disease control. Nipocalimab, a neonatal Fc receptor blocker, was associated with dose-dependent reductions in total IgG and anti-acetylcholine receptor (AChR) antibodies and clinically meaningful improvements in the Myasthenia Gravis Activities of Daily Living (MG-ADL) scale in patients with generalised myasthenia gravis in a phase 2 study. We aimed to assess the safety and efficacy of nipocalimab in a phase 3 study.

Study Hypothesis: Use of opioids for treatment of headache in the emergency department (ED) is associated with an increased 1-year risk of opioid-related adverse events.
Objective: To assess the safety and efficacy of opioid prescribing for ED patients with headache.
Methods: We performed a multicenter observational cohort study using linked administrative data.
Three-year treatment with anti-CGRP monoclonal antibodies modifies migraine course: the prospective, multicenter I-GRAINE study.
J Neurol

Clinical and Molecular Epidemiology, IRCCS San Raffaele Roma, Rome, Italy.
Objectives: To determine whether extending anti-CGRP mAb treatment beyond 3 years influences migraine course, we analyzed migraine frequency during the first month of treatment discontinuation following three 12-month treatment cycles (Ts).
Methods: This multicenter, prospective, real-world study enrolled 212 patients with high-frequency episodic migraine (HFEM) or chronic migraine (CM) who completed three consecutive Ts of subcutaneous anti-CGRP mAbs. Discontinuation periods (D1, D2, D3) were defined as the first month after T1, T2, and T3, respectively.
Spectrum, Time Course, Stages, and a Proposal for the Diagnosis of Histamine Intolerance in General Practice: A Nonrandomized, Quasi-Experimental Study.

Limited research has explored histamine intolerance from the perspective of primary caregivers. Our objective was to develop a practical symptom profile from the standpoint of general practice. We also aimed to gather data on the frequency and timing of disease progression and to establish a staging system.
