Alzheimer’s disease (AD) is a progressive neurodegenerative disease that is considered to be a major cause of dementia due to the increasing ageing of the population worldwide. It is a disease that severely affects patients’ daily activities, which has a significant impact on society (i.e., families, communities, and healthcare systems). According to estimates from WHO, more than 55 million people are living with dementia, and this number is expected to triple worldwide by 2050. The etiology of cognitive and memory impairment is still not fully understood. What is known so far about the pathogenesis of this disease includes several different causes leading to neurodegeneration, which follow each other and are closely linked.

Essential oils are complex mixtures of volatile compounds obtained from a single plant species via steam distillation, dry distillation, or mechanical processes. They are best known for their use in flavours, fragrances, and cosmetics, but have traditionally been used for many other purposes, including religious ceremonies and as therapeutic agents. Their traditional use has led to increasing attention being paid to their biological activity, including their activity at the level of the central nervous system.
