he word ‘placebo’ is Latin, meaning ‘I shall please,’ so the placebo effect can be seen as a sort of pleasing effect. Essentially that is all the placebo effect is; an inert substance that is given as a sham treatment to a patient in order to trigger a natural response, in the hopes of pleasing or alleviating the worries and ailments of the patient. In more scientific terms, “the true psychobiological placebo effect,” can be defined as a change in the patient’s “emotional state” (Benedetti, F. 2009). This means the mechanism of the placebo effect lies in the mind, showing how much power the mind has over our bodies and our wellbeing. I should clarify that the placebo effect does not heal illnesses, however it can cause an increased rate of improvement or acceptance of treatment. For example, cancer patients undergoing chemotherapy are often treated with a form of the placebo effect, in order to relieve them of side effects, such as nausea and general pain. This does not cure the patient, but rather eases their ailments. As a result of the accelerated rate, there is often an overall improvement to health and general wellbeing. There is much to be said about the expectation and the consequential intensity of the placebo effect, which will be explored later, but a fundamental concept of the placebo effect is that “trust, beliefs and expectations are crucial in placebo and placebo-related effects” (Benedetti, F. 2009). Parkinson’s disease is a motor neuron disease that affects approximately 1 in 500 people. It is degenerative and, as of now, has no cure. It is caused by the accumulation of toxic proteins, called alpha synuclein, in the part of the brain called the substantia nigra, that kill nerve cells and lead to the depletion of dopamine . Dopamine is a neurotransmitter; “a chemical that ferries information between neurons.” Electrical impulses are sent from our brains to our bodies via neurons found in the central nervous system, comprising of the brain and the spinal cord. These neurons can only pass on signals to other neurons using the chemical dopamine. It is an essential substance in all humans, and it regulates many of our bodily functions, such as movement, hence it plays such a key role in Parkinson’s disease. The most common symptoms and struggles of Parkinson’s disease include, but are not restricted to, tremors, brad>
