Observational Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07826221). This is a study registration, not published results. Lead sponsor: Assiut University. Recruitment status: NOT_YET_RECRUITING. Study type: OBSERVATIONAL. Enrollment: 100 participants (ESTIMATED). Conditions: Multiple Sclerosis, Primary Headache Disorders, Migraine Disorders, Tension-Type Headache. Primary outcome measures: Prevalence of Primary Headache Disorders , Baseline. Brief summary: Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the central nervous system that can cause a wide range of neurological symptoms. Headache is increasingly recognized as a common yet frequently overlooked symptom that significantly impairs quality of life and daily functioning in people with MS. While international reports suggest a high frequency of primary headache disorders, primarily migraine and tension-type headache, in individuals with MS, data evaluating headache patterns among Egyptian MS patients remain limited. The purpose of this observational study is to determine the prevalence and specific types of primary headache disorders among adults with MS attending Assiut University Hospitals, classified according to the International Classification of Headache Disorders, 3rd edition (ICHD-3). The study also aims to evaluate how headache disorders relate to patient demographics, MS disease duration and phenotype, neurological disability, MRI lesion characteristics, disease-modifying therapies, cognitive function, anxiety, and depression. Participants will complete a single-visit cross-sectional evaluation consisting of: * A detailed clinical interview and neurological examination covering medical history, MS course, and headache characteristics. * Neurological disability scoring using the Expanded Disability Status Scale (EDSS). * Review of brain and spinal cord magnetic resonance imaging (MRI) scans. * Standardized assessments for cognitive performance (Montreal Cognitive Assessment \[MoCA\]), anxiety (Hamilton Anxiety Rating Scale \[HAM-A\]), and depression (Hamilton Depression Rating Scale \[HAM-D\]). No experimental medications or procedural interventions are administered as part of this study.
