Alzheimer’s disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects a person’s ability to carry out daily activities. AD begins slowly. It first involves the parts of the brain that control thought, memory and language. People with AD may have trouble remembering things that happened recently or names of people they know. A related problem, mild cognitive impairment (MCI), causes more memory problems than normal for people of the same age. Many, but not all, people with MCI will develop AD.

The morphologic alterations of Alzheimer’s disease, presenile and senile dementia, have conventionally been associated with the cerebral cortex; however, it is clear that other areas of the brain, notably the hippocampus and amygdala, are involved as well. These structures, together with others such as the fornix, cingulate gyrus, septal nuclei, and mamillary bodies, constitute the limbic system, which has been recognized as the anatomic substrate of memory, emotion, and learning.

In this 7-hour module, we will be discussing the stages of the disease and how patients can benefit from the usage of essential oils as they are the only known substance that can pass the blood-brain barrier and possibly be the only effective treatment.
