Osmophobia in Patients With Migraine: A Systematic Review and Meta-Analysis.
World J Otorhinolaryngol Head Neck Surg | 2025
Systematic review / meta-analysisSummary
This study examined osmophobia in patients with migraine through systematic review. Researchers analyzed 58 studies involving 22,299 patients to determine osmophobia prevalence. The findings revealed that 48% of patients experienced osmophobia. Interestingly, 40% reported migraine attacks triggered by certain odors, particularly perfume. Patients with osmophobia were more likely to have other sensory disturbances. This included conditions like photophobia, aura, and nausea with increased odds ratios. The odds ratios for these disturbances were 1.45 for photophobia, 1.66 for aura, and 1.73 for nausea. Osmophobia is an important and often overlooked symptom in migraine patients. Many patients identified specific triggers, such as smoke or perfume, that worsened their migraines. However, true osmophobia prevalence is challenging to determine due to study selection criteria. Understanding osmophobia's role can help improve migraine diagnosis and treatment strategies for better patient management. Clinical relevance: This study highlights osmophobia as a significant migraine symptom, guiding diagnosis and treatment strategies for better patient outcomes.
Key Learning Points
- Nearly half of migraine patients experience osmophobia, which is a heightened sensitivity to smells.
- Certain odors, especially perfume, can trigger migraine attacks in about 40% of patients with osmophobia.
- Patients with osmophobia often have other sensory issues, such as increased sensitivity to light and nausea.
- Recognizing osmophobia can enhance the understanding and management of migraine symptoms.
- Determining the true prevalence of osmophobia is complicated due to variations in study methods.
