Learn about the brain and nervous system

Your brain and your nervous system work together to help you do things like see, smell, taste, feel, and move. Your nervous system sends signals to your brain to control these important functions. It also takes messages from your brain to your muscles, organs, and skin. But sometimes there is a problem, and the signals can't be sent. For example, with Parkinson's disease, nerve cells in the brain break down and can't send signals, so you may have trouble moving the way you want to. Other problems, like vertigo, happen when your sensing systems send false signals to your brain.

Our topics can help you learn more about your brain and nerve symptoms. Find out about certain diseases and disorders so you can understand the best treatment for your needs. To get started, explore these brain and nervous system topics:
