BACKGROUND
Photophobia is a debilitating feature of many headache disorders.
BACKGROUND
Clinical and preclinical research has identified several potential pathways involved in enhanced light sensitivity. Some of these structures include trigeminal afferents in the eye, second-order neurons in the
This study was performed to determine the efficacy of an anticephalgic photoprotective premedicated mask in the treatment of migraine and/or tension-type headaches. There were 54 patients. They were given masks and numbered bottles of topical medication containing either salicin or placebo. The
In order to evaluate photophobia and phonophobia in cluster headache (CH), light and sound-induced discomfort and pain thresholds were measured quantitatively in 50 patients and 50 sex-matched and age-matched headache-free controls. During bout (i.e., during the active period with attacks), CH
This study developed an integrated model of severity scores of migraine headache and the incidence of nausea, photophobia, and phonophobia to predict the natural time course of migraine symptoms, which are likely to occur by a common disease progression mechanism. Data were acquired from two phase 3
Introduction Research in development of new migraine therapeutics is hindered by the lack of suitable, predictive animal models. Cilostazol provokes headache in healthy humans and migraineurs by increasing intracellular cAMP levels. We aimed to investigate whether cilostazol could provoke
METHODS
A 19-year-old previously healthy man presented, minimally responsive, in respiratory distress to an ED after a 2-week history of headache, photophobia, and neck stiffness. Associated symptoms included low-grade fevers, malaise, and dark urine. He had no recent travel, ill contacts,
Migraine is a highly prevalent, disabling and complex episodic brain disorder whose pathogenesis is poorly understood, due in part to the lack of valid animal models. Here we report behavioral evidence of hallmark migraine features, photophobia and unilateral head pain, in transgenic knock-in mice
Migraine attacks are typically described as unilateral, throbbing pain that is usually accompanied by nausea, vomiting, and exaggerated sensitivities to light, noise and smell. The headache phase of a migraine attack is mediated by activation of the trigeminovascular pathway; a nociceptive pathway
Objective To review clinical and pre-clinical evidence supporting the role of visual pathways, from the eye to the cortex, in the development of photophobia in headache disorders. Background Photophobia is a poorly understood light-induced phenomenon that emerges in a variety of neurological and
This study investigated a potential association between visual factors and symptoms related to migraine. It was predicted that photophobia and visual aura would be positively associated with interictal light sensitivity and visual headache triggers (flicker, glare, and eyestrain), and Our objective was to compare the presence of self-reported unilateral photophobia or phonophobia, or both, during headache attacks comparing patients with trigeminal autonomic cephalalgias (TACs)--including cluster headache, short-lasting unilateral neuralgiform headache attacks with conjunctival
Sensitivity to light was investigated 5 and 8 h after consumption of an amino acid drink which contained L-tryptophan (balanced amino acid condition: 19 controls and 22 migraine sufferers) or which produced a short-term reduction in brain serotonin synthesis by omitting L-tryptophan (tryptophan
Photophobia refers to a sensory disturbance provoked by light. However, because it arises distinctly in a broad range of clinical conditions, its definition remains elusive. Many underscore the painful sensory aspects of photophobia, while others emphasize its unpleasant, affective qualities. To add
