Alzheimer's disease (AD) has been defined as a type of dementia that causes problems with memory, thinking, and behavior. AD is characterized by tau tangles and amyloid beta plaques in and around neurons, respectively. The impact this disease has on its victims' health, both physically and mentally, is unimaginable and the rate of progression is not expected to decrease any time soon. This threat to our minds encourages the importance of understanding AD. Amongst the theories as to what bio mechanisms cause the brain to intertwine is the amyloid cascade hypothesis. The purpose of this thesis is to review the amyloid cascade hypothesis and discuss treatments which utilize this model. We also wish to examine social aspects such as loneliness and socioeconomic factors which are associated with the progression of AD. Research presented provides evidence that targeting the accumulation of amyloid beta in the brain will prevent further biochemical responses to form neurodegenerative pathology. From the collected data, we observe that therapies targeting the amyloidogenic pathway have received positive feedback in the medical community. Amongst them, an amyloid beta synthetic peptide vaccine which made history in vaccine development due to their responder rate. The impact of social factors such as loneliness in the advancement of AD is also supported by research. While it is acknowledged that any neurodegenerative disease is far too complex to narrow its cause specifically, this thesis provides an association with multiple aspects that can be understood and applied to future research in this field.
