Alzheimer's Disease Mechanisms and Characteristics

What is Alzheimer's disease primarily characterized by?

• An autoimmune response leading to inflammation.

• The degeneration and death of neurons.

• A viral infection affecting brain tissue.

• A sudden onset of severe memory loss.

What term is used to classify Alzheimer's disease, referring to a category of brain disorders involving memory loss and cognitive impairment?

• Encephalitis

• Epilepsy

• Dementia

• Parkinsonism

What visible change is observed in the brains of individuals with Alzheimer's disease compared to healthy brains?

• Increased brain volume due to fluid retention.

• Regions of the brain appearing atrophied or shrunken.

• Enhanced neural connectivity and growth.

• Formation of new, larger neurons.

Which protein forms amyloid plaques, found in the extracellular space around neurons in Alzheimer's disease?

• Tau protein

• Alpha-synuclein

• Amyloid beta protein

• Prion protein

Which protein forms neurofibrillary tangles, found inside neurons in Alzheimer's disease?

• Amyloid beta protein

• Tau protein

• Huntingtin protein

• Apolipoprotein E

What are the two main types of misfolded protein clusters considered hallmark signs of Alzheimer's disease?

• Synaptic vesicles and neurotransmitter imbalances.

• Myelin sheaths and axonal degeneration.

• Amyloid plaques and neurofibrillary tangles.

• Glial cell proliferation and inflammation.

What is the primary mechanism of action for the most common treatments for Alzheimer's disease?

• Directly removing amyloid plaques from the brain.

• Inhibiting the activity of acetylcholinesterase.

• Stimulating the growth of new neurons.

• Reducing overall brain inflammation.

What is the intended effect of acetylcholinesterase inhibitors in treating Alzheimer's disease?

• To decrease levels of acetylcholine.

• To increase levels of acetylcholine.

• To prevent the formation of tau protein.

• To reverse neuronal death.
