“…These results are in accordance with those found in studies on adults 11,15 and on children at tertiary‐level centers 16 . The association between migraine and osmophobia has also been corroborated by other studies involving children and adolescents 16,17,19,20,22 …”

Objective.-The objectives of this study are to study osmophobia and odor-triggered headaches among headache pediatric patients.Background.-Achieving the correct diagnosis for headaches in younger children can be challenging. The presence of osmophobia could constitute a helpful piece of information for making the correct diagnosis of headaches among adults.Methods.-This was a cross-sectional study. Children and adolescents with headaches who were seen consecutively at a pediatric outpatient service and had at least 1 headache attack over the previous 12 months were included. We used a semi-structured questionnaire, Pediatric Migraine Disability Assessment, State-Trait Anxiety Inventory, and Children's Depression Inventory.Results.-About 300 patients were included; 253 had migraine, 47 had a tension-type headache; 137 had osmophobia during headaches (135 were migraineurs). "Osmophobia during headaches" for diagnosing migraine: Sensitivity: 54.4% (95% CI: 48.2%-60.5%); specificity: 95.8% (95% CI: 85.8%-98.8%); positive predictive value (PPV): 98.5% (95% CI: 94.8%-99.6%); negative predictive value (NPV): 28.5% (95% CI: 22.0%-36.0%). Osmophobia was associated with higher intensity (OR: 2.90; 95% CI: 1.63, 5.15; P < .001) and duration of the headache (OR: 5.73; 95% CI: 2.29, 14.3; P < .001) and with vomiting (OR: 3.56; 95% CI: 1.83, 6.96; P < .001) (logistic regression). There were 62 patients (all of them migraineurs) with odor-triggered headaches: sensitivity for diagnosing migraine: 24.9% (95% CI: 19.9%-30.6%); specificity: 100% (95% CI: 92.4%-100%), PPV: 100% (95% CI: 94.8%-100%), NPV: 20% (95% CI: 16%-26.0%). Odor-triggered headaches were associated with higher intensity (OR: 3.47; 95% CI: 1.64, 7.35; P = .001) and duration of the headache (OR: 3.28; 95% CI: 1.37, 7.86; P = .001), vomiting (OR: 2.37; 95% CI: 1.19, 4.74; P = .014), and phonophobia (OR: 2.40; 95% CI: 1.08, 5.32; P = .031) (logistic regression). Osmophobia was associated with higher-impact migraine (OR: 4.65; 95% CI: 1.30, 16.6; P = .018) and emergency care (OR: 4.65; 95% CI: 1.81, 12.0; P = .001) (logistic regression).Conclusions.-Osmophobia and odors as triggers for headaches are useful in diagnosing migraine and are markers for the severity of migraine in the pediatric population.

“…To the best of our knowledge, only 7 studies that have evaluated osmophobia and headaches in relation to the pediatric age range 16‐22 . Among these studies, only one presented values for sensitivity (27.1%), specificity (92%), PPV (82.3%), and NPV (44.8%) for the diagnosis of migraine among children and adolescents 16 .…”

“…It is possible that the complexity of the proposed criteria represents a significant barrier to their use as a diagnostic tool by primary care physicians in routine clinical practice ( 12 ). As a result of the considerable gap between the practices of researchers and clinicians ( 9 , 13 ), and the adoption of ICHD diagnostic criteria for migraine in a limited manner in clinical practice ( 12 ), there are variable data and limited statistical evaluations regarding the characteristics of migraine. Consideration needs to be given to the sensitivity and specificity of the items included in the diagnostic criteria for migraine in the literature ( 14 ).…”

An update to the International Classification of Headache Disorders is being developed, which may alter the diagnosis of disorders such as migraine headaches. Patients often report some, but not all, of the criteria for migraine without aura (MWoA), leading to several ‘grey zones’ that include patients who are not formally diagnosed with MWoA. The authors of this article assessed, in a total of 1365 patients diagnosed with MWoA, these ‘grey zones’ and possible implications for the update to the International Classification of Headache Disorders.

“…The 38 papers published between 1991 and 2016 (11–48) report validation studies from 18 different countries, with most papers from the US (n = 10) and Italy (n = 4). The papers report the validation of 30 tools, nine to diagnose or classify more than one headache type and 21 to classify or screen for one headache type only: Migraine (n = 18), cluster headache (n = 2), and probable medication overuse headache (n = 1) (Table 1).…”

Diagnostic and classification tools for chronic headache disorders: A systematic review

et al. 2018

Background or aim Despite guidelines and the International Classification of Headache Disorders (ICHD-III beta) criteria, the diagnosis of common chronic headache disorders can be challenging for non-expert clinicians. The aim of the review was to identify headache classification tools that could be used by a non-expert clinician to classify common chronic disorders in primary care. Methods We conducted a systematic literature review of studies validating diagnostic and classification headache tools published between Jan 1988 and June 2016 from key databases: MEDLINE, ASSIA, Embase, Web of Knowledge and PsycINFO. Quality assessment was assessed using items of the Quality of Diagnostic Accuracy Studies (QUADAS-2). Results The search identified 38 papers reporting the validation of 30 tools designed to diagnose, classify or screen for headache disorders; nine for multiple headache types, and 21 for one headache type only. We did not identify a tool validated in a primary care that can be used by a non-expert clinician to classify common chronic headache disorders and screen for primary headaches other than migraine and tension-type headache in primary care. Conclusions Despite the availability of many headache classification tools we propose the need for a tool that could support primary care clinicians in diagnosing and managing chronic headache disorders within primary care, and allow more targeted referral to headache specialists.
