**4. The potential of essential oils in neurodegenerative disease treatment**

Considering the improved life expectancy, NDs are undoubtedly debilitating conditions affecting older populations or people. Because NDs remain incurable, efforts towards discovering and developing molecules with preventive and neuroprotective potential of neurodegeneration are important. EOs effectiveness and their respective antioxidant components are never in doubt in age-related NDs as they can halt OS. The neuroprotective and anti-aging characteristics of EOs have been explored in many kinds of research, having been adjudged as relatively non-toxic compared with other conventional therapy of NDs [27–29]. Efforts have been made in this chapter to majorly review various in vitro and in vivo studies using EOs as preferred candidates for managing and treating NDS in particular AD, PD, ALS and HD in **Table 2**.
