Abstract
Alzheimer's disease has been a case study for a long time, discoveries brought hypotheses and reasons related to the disease mechanism. This study aims to bring a clear understanding of the significant impact of human actions such as diet and Alzheimer's disease. Diet indirectly impacts the human body and significantly the brain, in the case of memory disorder diet affects the neurotransmitters that play an important role in the function of the brain and memory. The study used various relations between variables, hypotheses show that a transmembrane protein plays a key role in neurodegeneration and later it disturbs the neurotransmitter’s function. Through the study, information showed that diet styles cause oxidative stress which is considered one of the main reasons that cause neurodegeneration. The study shows the impact of each variable on the other and leads these findings to the main case study of Alzheimer's disease.
