The tangles are more clearly linked to brain cell death than amyloid is.
FORBES: Eli Lilly Setback Could Pave Way For New Alzheimer's Approach
She has shown in mouse experiments that eliminating the amyloid-producing genes called presenilin produces dementia and brain cell loss.

He said narcolepsy was linked to a loss of a particular type of brain cell called a hypocretin neuron.
Nerve-cell precursors can turn into two types of brain cell besides nerve cells.
ECONOMIST: Brain development may be influenced by genetic parasites
The idea that more brain cell activity could lead to more amyloid-beta build up is an exciting, if sobering, finding.
FORBES: Wandering into Alzheimer's: Could Your Thoughts Reduce Your Risk?
Revealingly, the new gene, called neuregulin-1, turns out to be involved in brain cell "plasticity, " the rewiring process that enables learning.
It is also suspected that brain cell death in Parkinson's patients is caused by over-activity of another brain chemical called glutamate.
At birth, the human brain has formed about 2, 500 synapses the connections that allow the brain to pass along signals per brain cell.
The study also found other evidence that brain cell death was at a higher level in the rats with a normal diet.
It is thought that Parkinson's is linked to the death of a certain type of brain cell that produces a chemical called dopamine.
By clearing out those deposits or halting their production, researchers hope to slow brain cell death and alter the course of the illness.
Evidence to bolster this theory comes from research showing that existing depression treatments all seem to spur brain cell production--just not as efficiently as we'd like.
Research at UCLA found that too much time spent on social media and too little time in social interaction is stimulating brain cell alteration and neurotransmitter release.
The hope was that this would restore brain cell activity in the thalamus, a relay station that integrates input from many parts of the brain, helping make consciousness possible.
While it is unpopular with the masses who now prove they vote without using a single brain cell, our President and his party are spending the United States into bankruptcy.
FORBES: Weasel Words Atop Fiscal Cliff: Congress Can't Avoid Tax Hikes By Closing 'Loopholes'
They categorised facial dimensions such as the distance between the eyes, then recorded the electrical activity of one brain cell at a time while they showed cartoons to the macaques.
The dominant explanation of Alzheimer's disease contends that the massive brain cell death is due to the buildup of plaques containing a protein called beta amyloid built up in the brain.
Researchers are discovering that daily exposure to computers, smart phones, video games, Internet search engines, etc. stimulates brain cell alteration and neurotransmitter release, gradually strengthening new neural pathways while weakening old ones.
Therefore, I predict that anyone with even a brain cell's worth of adventure will be less intimidated by the thought of Linux on Alpha than they would have been by NT on Alpha.
Experts said the findings could be important for future research into brain cell repair in patients with neurodegenerative diseases such as Alzheimer's disease and, importantly, that studies in mice would be applicable to humans.
When she created a strain of mice with the presenilin genes missing in their brains, the mice developed dementia and brain cell death just like Alzheimer's sufferers, but the mice had no amyloid deposits.
That's not a test you'd want to try at home, because rather than extract a brain cell, you can always ask your parents when you were born but it did lead Frisen down some interesting paths.
This theory, proposed by Jacobs with collaborators at the Salk Institute, and independently by a Yale University team, was inspired by the stunning finding in the 1990s that adults can sprout new brain cells throughout life, contrary to decades of dogma that adult brain cell counts are fixed.
Guilford researchers hope to find a chemical that can block this enzyme, thereby stopping the toxic effects of glutamate without having to bludgeon brain-cell receptors with noxious chemicals.
The other concept, pursued by Pfizer, Japan's Ono Pharmaceutical, the AstraZeneca-Renovis partnership and numerous other firms, is to find a brain-cell protector that could be used to stabilize nerve cells and prevent further damage.
"The human brain is sensitive to the electromagnetic radiation emitted by cell phones, but for the brain to be impacted, the cell phone has to be close to the head, " Volkow said.
