A prevalent hypothesis for the cause of this disease is the accumulation of extracellular amyloid beta plaques in the brain. For 10 points each:
[10e] Name this disease that is the most common cause of dementia. An early symptom of this neurodegenerative disease is short-term memory loss.
ANSWER: Alzheimer’s disease [or AD]
[10h] Another hallmark of Alzheimer’s disease is intracellular accumulation of neurofibrillary (“neuro-FIB-rill-ary”) tangles of this protein. This microtubule-associated protein aggregates into an insoluble form when hyperphosphorylated (“hyper-foss-FOR-il-ay-ted”).
ANSWER: tau proteins [accept tubulin associated unit proteins]
[10m] This region of the brain responsible for memory consolidation is one of the first to be damaged in Alzheimer’s patients. This region of the brain forms part of the limbic system and has a seahorse shape.
ANSWER: hippocampus [or hippocampus proper or hippocampi]
