  • Q1
    What is Alzheimer's disease?
    Alzheimer's disease is a neurodegenerative disorder that causes muscle tremors, muscle stiffness, and slowing of movements.
    Alzheimer's disease is a neurodegenerative disease characterized by progressive memory loss, cognitive deterioration, and personality changes.
    Alzheimer's disease is an inherited disease that causes the progressive breakdown of nerve cells in the brain, causing uncontrolled movements, emotional problems, and loss of cognition.
    Alzheimer's disease is a disease in which the immune system attacks the myelin sheath of the central nervous system causing issues with vision loss, pain, fatigue, and coordination.

  • Q2
    This is a type of disease in which cells of the central nervous system stop working or die. It usually gets worse over time and has no cure.

    Physiological disease
    Genetic deficiency disease
    Infectious disease

    Huntington's disease
    Frontotemporal dementia
    Alzheimer's disease
    Parkinson's disease

  • Q4
    What is the prevalence of Alzheimer's disease in the United States?
    1 in 50 people over age 65 have Alzheimer's disease.
    1 in 100 people over age 65 have Alzheimer's disease.
    1 in 25 people over age 65 have Alzheimer's disease.
    1 in 10 people over age 65 have Alzheimer's disease.

  • Q5
    Which of the following is NOT a physical characteristic found in the brains of people with Alzheimer's disease?
    Brains with Alzheimer's disease have larger spaces between folds (sulci).
    Brains with Alzheimer's disease have smaller spaces between folds (sulci).
    Brains with Alzheimer's disease have smaller folds (gyri).
    Brains with Alzheimer's disease are smaller.
    30s
  • Q6
    This is a ridge or fold in the cerebral cortex of the brain.
    Gyrus
    Dendrite
    Sulcus
    Ventricle
    30s
  • Q7
    This is a groove or furrow in the cerebral cortex of the brain.
    Sulcus
    Gyri
    Axon
    Ventricle
    30s
  • Q8
    Changes in brain size in patients with Alzheimer's disease are directly due to:
    the death of neurons.
    the build up of beta amyloid plaques.
    the occurrence of neurofibrillary tangles.
    the expanding of brain ventricles.
    30s
  • Q9
    This protein, located in the cell membrane of neurons, plays a role in neural growth and repair but, when dysfunctional, can be associated with the development of Alzheimer's disease.
    Elastin Protein
    Amyloid Precursor Protein
    Tau Protein
    Histone Protein
    30s
  • Q10
    In a healthy human brain, beta amyloid strands are small. They are broken down and eliminated.
    False
    True
    30s
  • Q11
    In a healthy human brain, beta amyloid strands are long and sticky. They stick together and form plaques outside of neurons in the brain.
    False
    True
    30s
  • Q12
    It is hypothesized that these plaques interfere with cell communication and stimulate the immune response, resulting in the death of neurons.
    Gamma Amyloid Plaques
    Beta Amyloid Plaques
    Alpha Apoxy Plaques
    Tau Amyloid Plaques
    30s
  • Q13
    Tau proteins play a role in stabilizing microtubules in the axons of neurons.
    True
    False
    30s
  • Q14
    It is hypothesized that the tangling of these proteins causes microtubules in neurons to break down, resulting in cell communication problems and cell death.
    Alpha tag proteins
    Gamma ray proteins
    Tau proteins
    Beta amyloid proteins
    30s
  • Q15
    Which of the following is NOT known to be preventive in the development of Alzheimer's disease?
    Healthy diet
    High quality sleep
    Daily intake of red wine
    Regular exercise
