Seizure treatment with olfactory training: a preliminary trial

Area of Science:

• Neurology
• Complementary and Alternative Medicine
• Olfactory Research

Background:

• Epilepsy affects millions globally, with a significant portion experiencing drug-resistant seizures.
• Current treatments have limitations, necessitating exploration of novel therapeutic strategies.
• Olfactory dysfunction is sometimes observed in epilepsy patients, suggesting a potential link.

Purpose of the Study:

• To investigate the efficacy of olfactory training with lavender aroma as a complementary therapy for drug-resistant epilepsy.
• To assess the impact of olfactory training on seizure parameters, quality of life, and olfactory function.
• To evaluate the safety and tolerability of this intervention.

Main Methods:

• A 3-month study involving 24 patients (pediatric and adult) with drug-resistant epilepsy.
• Participants performed olfactory training with lavender aroma (Lavandula Angustifolia) twice daily.
• Seizure frequency, duration, quality of life, and olfactory function were assessed before and after the intervention.

Main Results:

• Olfactory training led to a statistically significant decrease in seizure frequency (p < 0.001) and duration (p = 0.02).
• A 50% reduction in seizures was observed across the patient group.
• Quality of life (p = 0.003) and olfactory function (p = 0.017 for pediatric, p = 0.05 for adult) showed significant improvement.
• No adverse reactions or increased seizure frequency were reported.

Conclusions:

• Olfactory training with lavender aroma is a safe and effective complementary therapy for drug-resistant epilepsy.
• The intervention demonstrates potential to improve seizure control and overall well-being.
• Further large-scale studies with extended follow-up are warranted to establish olfactory training as a standard therapeutic option.
