Alzheimer's disease. Conceptual artwork of a brain and nerve cells to depict dementia due to Alzheimer's disease. A sagittal slice through the brain is overlain with nerve cells. The nerve cells (neurones) with long axons and dendrites,and cell bodies (triangular-shaped),appear tangled. In Alzheimer's disease tangled protein filaments occur within the nerve cells and lesions of beta-amyloid protein develop. Brain cells also shrink and die (lower right). Alzheimer's disease is the most common cause of old age dementia. In this disease there is a general decline in mental ability which progressively worsens over time | |
