The neural basis of somatosensory temporal discrimination threshold as a paradigm for time processing in the sub-second range: An updated review.

Background And Objective: The temporal aspect of somesthesia is a feature of any somatosensory process and a pre-requisite for the elaboration of proper behavior. Time processing in the milliseconds range is crucial for most of behaviors in everyday life. The somatosensory temporal discrimination threshold (STDT) is the ability to perceive two successive stimuli as separate in time, and deals with time processing in this temporal range.

Concurrent tonic pupil and trochlear nerve palsy in COVID-19.

Since COVID-19 was first reported, different neurological complications have been acknowledged, but their description is constantly evolving. We report a case of concurrent tonic pupil and trochlear nerve palsy in this context. A 62-year-old man reported a 5-day history of binocular vertical diplopia and blurred vision in his left eye, noticing that his left pupil was dilated.

Transcutaneous Supraorbital Stimulation as a Preventive Treatment for Chronic Migraine: A Prospective, Open-Label Study.

Background And Objective: Successful preventive treatment in chronic migraine (CM) remains an unmet need in some cases, and new therapeutic strategies are emerging. We aimed to test the effect of noninvasive, transcutaneous supraorbital nerve stimulation (tSNS) in a group of patients with CM.

Patients And Methods: This was an open label, quasi-experimental design.

Stress, Coping, and Personality in Patients with Epicrania Fugax, and Their Relation to the Clinical Characteristics of Pain.

Objective: The aim of the present work is to analyze certain psychological features in a group of patients diagnosed with Epicrania fugax (EF; that has been recently included in the appendix of the International Classification of Headache Disorders, third edition, beta version), as well as their association with diverse demographic and clinical characteristics of the sample.

Design: Case-control.

Method: Perceived Stress Scale (PSS), Stress Coping (COPE), Big Five Personality Traits (NEO-FFI), Depression (BDI-II), and Trait Anxiety (STAI) were evaluated in 23 patients with EF and 23 matched healthy controls.

Pain Paroxysms With Coronal Radiation: Case Series and Proposal of a New Variant of Epicrania Fugax.

Objective: We aim to report 4 patients with brief pain paroxysms whose clinical features remind of typical epicrania fugax (EF), except for the direction along a transverse trajectory.

Background: EF has been defined as a brief paroxysmal head pain, with stabbing quality, describing a linear or zig-zag trajectory across the surface of one hemicranium.

Methods: We considered all patients attending the headache outpatient office at 3 tertiary hospitals from March 2008 to December 2015.

Increase in body temperature during migraine attacks.

Introduction: Intermittent fever has been occasionally related to migraine, either as a migraine equivalent or as a migraine accompaniment. We present a case of recurrent increase in body temperature consistently associated with migraine headaches.

Methods: A 15-year-old girl reported a 3-year lasting history of migraine without aura, with a feeling of warmth occurring in each episode.

Epicrania fugax: 19 cases of an emerging headache.

Objective: Epicrania fugax (EF) is a primary headache of recent description. We aimed to report 19 new cases of EF, and thus contribute to the characterization of this emerging headache.

Background: EF is characterized by painful paroxysms starting in a particular area of the head, and rapidly radiating forwards or backwards through the territories of different nerves.

Wallenberg's syndrome and symptomatic trigeminal neuralgia.

Symptomatic trigeminal neuralgia due to a brainstem infarction is said to be rare. However, facial pain is not uncommon in Wallenberg's syndrome. Facial pain related to a Wallenberg's syndrome may be either persistent of intermittent, and occasionally occurs in brief attacks.
