Alzheimer’s Disease: Plaques & Tangles Plaques build up between nerve cells. They contain deposits of a protein fragment called beta-amyloid. Beta-amyloid is naturally removed in the normal brain. Tangles are twisted fibers of another protein called tau. Tau helps maintain structure of the normal neuron.

Alzheimer’s Disease: Treatment Alzheimer’s disease damages or destroys cells that produce and use acetylcholine, reducing amounts available to carry messages. Cholinesterase inhibitors (e.g. Aricept ) increase levels of acetylcholine. By maintaining acetylcholine levels, the drug may help compensate for the loss of functioning brain cells. Cholinesterase inhibitors do not stop the underlying destruction of nerve cells. Their ability to improve symptoms eventually declines as brain cell damage progresses.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
