Parkinson’s disease is another brain disorders that primarily affect movement. Usually it begins with symptoms such as pushing (trembling), muscle stiffness, slowing movements and difficulty with equilibrium and coordination. Parkinson is caused by the loss of nerve cells that produce dopamine, chemist important for movement control. Unlike Alzheimer, Parkinson often starts earlier, approximately 50 to 65 years. While Parkinson mainly affects the movement, some people develop dementia later, known as Parkinson’s disease. This dementia affects the solution, the speed of thinking, memory search and mood. It also often includes hallucinations and delusions that are less common in Alzheimer’s dementia.
