- Q1What 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.30s
- Q2This 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.Neurodegenerative diseasePhysiological diseaseGenetic deficiency diseaseInfectious disease30s
- Q3What is the most common cause of dementia in the United States?Huntington's diseaseFrontotemporal dementiaAlzheimer's diseaseParkinson's disease30s
- Q4What 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.30s
- Q5Which 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
- Q6This is a ridge or fold in the cerebral cortex of the brain.GyrusDendriteSulcusVentricle30s
- Q7This is a groove or furrow in the cerebral cortex of the brain.SulcusGyriAxonVentricle30s
- Q8Changes 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
- Q9This 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 ProteinAmyloid Precursor ProteinTau ProteinHistone Protein30s
- Q10In a healthy human brain, beta amyloid strands are small. They are broken down and eliminated.FalseTrue30s
- Q11In a healthy human brain, beta amyloid strands are long and sticky. They stick together and form plaques outside of neurons in the brain.FalseTrue30s
- Q12It is hypothesized that these plaques interfere with cell communication and stimulate the immune response, resulting in the death of neurons.Gamma Amyloid PlaquesBeta Amyloid PlaquesAlpha Apoxy PlaquesTau Amyloid Plaques30s
- Q13Tau proteins play a role in stabilizing microtubules in the axons of neurons.TrueFalse30s
- Q14It 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 proteinsGamma ray proteinsTau proteinsBeta amyloid proteins30s
- Q15Which of the following is NOT known to be preventive in the development of Alzheimer's disease?Healthy dietHigh quality sleepDaily intake of red wineRegular exercise30s
