Following the Diagnosis Journey of a Patient with an Unknown Type of Dementia
Alzheimer’s disease (AD) is a devastating disorder that affects the lives of both patients and their loved ones. While it is believed that AD is due to a buildup of amyloid plaques in the brain that eventually lead to the formation of neurofibrillary tangles (NFTs) and result in neurodegeneration, there are many theories that attempt to define the causes of AD. This paper investigates the amyloid and tau theories in more detail, including how these proteins can spread in the brain. It will also take a look into other potential theories that could contribute to AD symptoms such as vascular issues or neuroinflammation. Frontotemporal dementia (FTD) is another form of dementia, albeit much rarer than AD, that is typically characterized by symptoms that follow the opposite progression of AD: behavior and judgement are affected before memory. In addition, FTD is closely related to amyotrophic lateral sclerosis (ALS), a movement disorder that is caused by a loss of motor neurons that results in loss of muscle control. This paper will also examine how FTD and ALS are related, as well as theories behind the potential causes of these disorders. Finally, this paper will examine a patient who exhibits signs and symptoms of both disorders to attempt to determine the potential diagnosis.
