PATHOPHYSIOLOGY REVIEW SHEET FULL
SOLUTIONS
●● Name two common neurodegenerative disorders.
Answer: Dementia and Parkinson's disease.
●● What is the impact of neurodegenerative disorders on families?
Answer: They can significantly affect friends and family even before
total care is required.
●● What common pathological mechanisms are shared by
neurodegenerative diseases?
Answer: Protein misfolding, neuroinflammation, oxidative stress, and
neuronal loss.
●● At what age do symptoms of Parkinson's disease typically begin?
Answer: Most clients usually start having symptoms in their 60s, but it
can occur as early as 40.
●● What area of the brain is primarily affected by Parkinson's disease?
Answer: The substantia nigra in the basal ganglia.
,●● What is Amyotrophic Lateral Sclerosis (ALS)?
Answer: A progressive condition that targets motor neurons, leading to
muscle weakness and atrophy.
●● What are the symptoms of Huntington's disease?
Answer: Uncontrolled movements, emotional disturbances, and
cognitive decline.
●● What is Multiple Sclerosis (MS)?
Answer: An autoimmune disorder that damages the myelin sheath in the
central nervous system, presenting with a wide range of neurological
symptoms.
●● What is Myasthenia Gravis (MG)?
Answer: An autoimmune disorder affecting the communication between
nerves and muscles, leading to muscle weakness and fatigue.
●● What characterizes Alzheimer's disease (AD)?
Answer: Accumulation of amyloid plaques and tau tangles in the brain,
leading to neuronal death and cognitive decline.
●● What causes vascular dementia?
Answer: Conditions that block or reduce blood flow to the brain, often
following a stroke.
,●● What are the symptoms of Lewy Body Dementia?
Answer: Cognitive decline, fluctuating alertness, visual hallucinations,
and Parkinsonian motor symptoms.
●● What is Frontotemporal Dementia (FTD)?
Answer: A type of dementia involving degeneration of nerve cells in the
frontal and temporal lobes, affecting behavior and language.
●● What is the importance of early diagnosis in neurodegenerative
disorders?
Answer: It can significantly impact treatment effectiveness in slowing
degeneration and maintaining neurologic function.
●● What are the pathological changes in Alzheimer's disease?
Answer: Accumulation of amyloid-beta plaques and tau protein tangles
leading to neuronal damage and loss.
●● What role do neuroinflammatory responses play in Alzheimer's
disease?
Answer: They contribute to preventing the breakdown of beta-amyloid
and the formation of plaques.
, ●● How does Alzheimer's disease affect emotional and behavioral
symptoms?
Answer: Cognitive decline can exacerbate or trigger emotional and
behavioral symptoms.
●● What is the genetic risk factor for early-onset Alzheimer's disease?
Answer: Related to genetic autosomal dominance in three different
genes.
●● What is the role of the APOE gene in Alzheimer's disease?
Answer: APOE gene mutations can increase susceptibility to
Alzheimer's disease, particularly APOE ε4.
●● What is the most common allele of the APOE gene?
Answer: APOE ε3, which is believed not to affect the risk of
Alzheimer's.
●● What is the protective allele of the APOE gene?
Answer: APOE ε2, which may delay the onset of Alzheimer's disease.
●● What is the significance of multidisciplinary teams in Alzheimer's
care?
Answer: They can provide comprehensive support, including managing
psychiatric symptoms associated with the disease.
