Therefore, as more and more of the cells die, it causes the brain to shrink. What causes the brain cells to die, which then causes the brain to contract, is the unusual twist of the protein called tau. Tau is a protein in the brain that delivers nutrients and other important elements to the brain cells. The effect of the twisted protein inhibits the…

  • Causes Of Parkinson's Disease

    Parkinson 's Disease is caused by the death of dopamine-generating cells in a region in the midbrain called the substantia nigra. When dopamine levels decrease, it causes abnormal brain activity, leading to signs of Parkinson 's disease. The dopamine released by nerve cells of the substantia nigra stimulates another brain region, the corpus striatum. Without enough dopamine, the corpus striatum cannot control its targets, and so on down the line. Ultimately…
