Effects of Essential Oils and Aromatic Plants on Alzheimer’s Disease and Dementia

The primary objective of this research was to investigate how beneficial essential oils and aromatic plants are at curing Alzheimer’s disease and dementia. Alzheimer’s Disease (AD) is known to be one of the most incurable prevalent diseases in the elderly. Agitation, cognitive impairments, communication difficulty, irritability, and confusion may advance in AD patients. Even though the behavioral causes contributing to the disease have not yet been discovered, aggregation of tau and amyloid proteins is found in the brain of patients with Alzheimer’s. With numerous experiments conducted on these proteins, scientists have surmised that this accumulation is a causative factor of Alzheimer’s disease. Multiple scientists and experts have carried out several studies regarding the enlargement of amyloid plaques on Alzheimer’s. In addition, the effects of aromatherapy, including divergent results of alternative essential oils, have been analyzed. This paper examines the distinctions between Alzheimer's disease and dementia. The review elaborates on the causes and the symptoms before describing the effects of essential oils and aromatic plants. Subsequently, this provides rudiments regarding the benefits and hazards of applying essential oils and aromatic plants to treat either Alzheimer's disease or dementia. This study focuses on utilizing essential oils and aromatic plants in the medical profession as an alternative treatment for Alzheimer's disease and dementia. Likewise, a couple of case studies are shown in the paper with the analysis of amyloid plaques in mice and the effectiveness of lavender, rosemary, and orange essential oils on participants.
