Compare and contrast the pathophysiology between Alzheimer's disease and
frontotemporal dementia.
Alzheimer's disease and frontotemporal dementia are both neurodegenerative diseases
that result in progressive cognitive decline. Alzheimer's disease is the most common form of
dementia and is characterized by the accumulation of abnormal proteins and the loss of neurons
in the brain. The primary cause of neuronal loss is abnormal amyloid beta and tau protein
deposits (Kumar et al.,2022). These proteins are found in the hippocampus, an area of the brain
responsible for memory, and cause the nerve cells in that area to become damaged and
eventually die. As the neurons die, the hippocampus shrinks, resulting in a loss of memory and
cognitive abilities (Knopman et al., 2021). In contrast, frontotemporal dementia is caused by the
degeneration of neurons in the frontal and temporal lobes of the brain (McCance & Huether,
2019). These brain areas are responsible for higher-order functions such as language, behavior,
and decision-making. As these neurons degenerate, the patient experiences a decline in their
ability to communicate and changes in their personality and behavior. While both diseases have a
similar end result, their causes and symptoms differ. Alzheimer's disease is caused by the
accumulation of abnormal proteins which damage the neurons in the hippocampus, resulting in a

language and communication, as well as changes in behavior and personality (McCance &

2. Identify the clinical findings from the case that supports a diagnosis of
Alzheimer's disease.
Based on the clinical presentation and diagnostic findings, the patient was diagnosed with
Alzheimer's type dementia. Specifically, the patient presented with several symptoms consistent
with Alzheimer's disease, including memory loss, difficulty with decision-making, difficulty
dressing, and disorientation. Additionally, the patient's PMH was significant for a family history
of Alzheimer's, as his father had passed away due to a decline associated with the disease.
Furthermore, the Mini-Mental State Examination (MMSE) results revealed a baseline score of 12
out of 30, indicating moderate dementia. Lastly, the MRI revealed hippocampal atrophy, a
hallmark of Alzheimer's disease. These findings all support a diagnosis of Alzheimer's type
dementia.
3. Explain one hypothesis that explains the development of Alzheimer's disease
One hypothesis that explains the development of Alzheimer's disease is known as the
amyloid cascade hypothesis. This hypothesis suggests that the accumulation of a protein known
as an amyloid beta in the brain is responsible for the development of Alzheimer's disease.
Amyloid beta is produced in small amounts and is typically cleared away by the body's natural
processes. However, in cases of Alzheimer's disease, the amyloid beta is not cleared away and
instead accumulates in the brain. This accumulation of amyloid beta is thought to destroy
neurons and cause other neurological damage, which leads to the development of Alzheimer's
disease. The accumulation of amyloid beta is thought to be caused by a combination of genetic
and environmental factors. It is believed that certain genetic variations cause the body to be less
effective at clearing away the amyloid beta, thus leading to its accumulation in the brain.
Environmental factors such as exposure to certain toxins or infections may also contribute to the

accumulation of amyloid beta and the development of Alzheimer's disease. The cascade of
events in the environment increases the accumulation of amyloid beta, which is thought to lead
to the development of Alzheimer's disease. The accumulation of amyloid beta is thought to cause
an inflammatory response in the brain, which leads to the death of neurons and other
neurological damage. This neurological damage is thought to lead to cognitive decline and other
symptoms associated with Alzheimer's. Additionally, the accumulation of amyloid beta is
thought to lead to plaques and tangles in the brain, which are associated with Alzheimer's disease
( Uddin et al., 2022).
Overall, the amyloid cascade hypothesis is one hypothesis that explains the development
of Alzheimer's disease. This hypothesis suggests that the accumulation of amyloid beta in the
brain is responsible for the development of Alzheimer's disease and is caused by a combination
of genetic and environmental factors. This accumulation of amyloid beta is thought to lead to a
cascade of events that ultimately lead to the development of Alzheimer's disease.
4. Discuss the patient's likely stage of Alzheimer's disease.
There are five stages of Alzheimer's disease, preclinical, mild cognitive impairment, mild
dementia, moderate dementia, and severe dementia (Mayo Clinic, 2021). During the moderate
dementia stage of Alzheimer's, people get more confused and forgetful and need more help with
daily activities and self-care. Some patients experience increasingly poor judgment, deepening
confusion, and more significant memory loss, affecting their daily activities and undergoing
significant changes in personality and behavior. Based on the patient's clinical presentation and
diagnostic findings, the patient is likely in the moderate stage of Alzheimer's disease. In this
stage, the patient will experience more severe memory loss, confusion, and difficulty with
activities of daily living. Memory problems are particularly prominent in this stage, as the patient
