There are a couple of scenarios we go through as we are conceived, grow and become older. If one part of the system fails to carry out its function properly the effects will vary depending on where in the life-cycle this happen, and what part of the body.The nervous system also regulates the actions of most other body systems, such as blood flow and blood pressure.The nervous system allows you to be conscious and have thoughts, memories, and language.If the nervous system isn't functioning correctly, then your perceptions and ability to move and function are altered. You may experience the sudden onset of one or more symptoms, such as: Numbness, tingling, weakness, or inability to move a part or all of one side of the body (paralysis). Dimness, blurring, double vision, or loss of vision in one or both eyes. Loss of speech, trouble talking, or trouble understanding speech.
