Aromatherapy—the use of essential oils from plants for therapeutic purposes—has shown potential in supporting patients with Alzheimer’s disease (AD), primarily by improving behavioral symptoms, cognition, and quality of life
-Some essential oils (like rosemary and sage) inhibit acetylcholinesterase (AChE), boosting acetylcholine levels similar to AD drugs.
-Many essential oils reduce oxidative stress and inflammation, both implicated in AD pathology.
-Aromatherapy may affect GABAergic and serotonergic pathways, calming agitation and improving mood.
