Background: Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a severe headache disorder characterized by clustered episodes of extreme pain. Refractory to most interventions, ipsilateral unilateral ventral tegmental area (VTA) deep brain stimulation (DBS) has been previously reported to be efficacious in 14 cases.
Methods And Results: Herein, we report the first case of an individual with medically refractory SUNCT who underwent bilateral VTA DBS. The patient experienced better improvement of his headaches with bilateral stimulation compared to unilateral stimulation. He also had a return of severe headaches within a few hours after his stimulator was switched off during sleep, with rebound worsening of his headaches over several days. The main side effects were double vision and difficulty focusing while reading, which were observed primarily with unipolar stimulation that required high voltages, high frequencies, and multiple negative contacts to control the headaches. The side effects were minimized with bipolar and interleaving stimulation with comparable control of his headaches.
Conclusion: Bilateral VTA DBS may be effective in alleviating medical refractory SUNCT.

•The trigeminal autonomic cephalalgias are a severe disabling form of primary headache disorders characterized by severe unilateral pain commonly associated with ipsilateral cranial autonomic features as well as a sense of restlessness or agitation, of which the most common is cluster headache.•Different forms of trigeminal autonomic cephalalgias include cluster headache, paroxysmal hemicrania (PH), hemicrania continua (HC), short lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT)/short lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) and are differentiated based on their duration and frequency•Triptans, such as sumatriptan by injection, high flow 100 % oxygen by face mask, or non-invasive vagus nerve stimulation, are mainstay acute treatments of attacks of cluster headache.•Interim preventive treatments to reduce attack frequency include a short course of high dose oral corticosteroids, local anesthetic/corticosteroid injection around the homolateral (to pain) greater occipital nerve or the CGRP monoclonal antibody galcanezumab.

Article Synopsis
- - The study aimed to investigate the effects of low-dose oral psilocybin, along with psychological support, on patients suffering from chronic short-lasting unilateral neuralgiform headache attacks (SUNHA), focusing on cognitive impact, safety, and headache severity.
- - Participants received ascending doses of psilocybin (5, 7.5, and 10 mg) over three sessions, but recruitment challenges limited the study to four enrolled patients, with only three completing it.
- - Results indicated no significant adverse effects, but cognitive function data could not be collected due to high subjective dose intensity, and headaches remained severe throughout the trial with minimal observed changes in headache frequency or severity.

Background: To synthesize the available epidemiologic data on short-lasting unilateral neuralgiform headache attacks (SUNHA). This, in turn, might inform diagnostic work-up and clinical decision-making.
Methods: EMBASE and PubMed were searched for observational studies reporting on the prevalence or relative frequency of SUNHA or its individual clinical features.
Harlequin syndrome in a patient with probable hemicrania continua and exertional headache - is there a link? a case report.

Article Synopsis
- Harlequin syndrome is a rare disorder of the autonomic nervous system causing reduced facial flushing and sweating on one side, typically triggered by heat or activity, and often occurs without a clear cause.
- The case study follows a 42-year-old woman with a history of unilateral headaches and autonomic symptoms, later diagnosed with harlequin syndrome and Sjögren's syndrome after multiple diagnostic tests.
- The report suggests a potential link between harlequin syndrome and trigeminal autonomic headache disorders, as this is the first documented case connecting harlequin syndrome with a headache similar to hemicrania continua.
