Don't lose your nerves over things that can be fixed!
Nervous system diseases are very widespread today. This is due to many internal and external environmental factors. Nervous system diseases can present not only on their own but also as diseases and symptoms of other organs. The most dangerous aspect of nervous system diseases is that nerve cells have a very limited ability to repair themselves (regenerate) once they are destroyed.
The nervous system is divided into two main parts: the central (brain and spinal cord) and the peripheral (the nerves arising from the brain and spinal cord and the nerves of the limbs). Diseases originating in the nervous system itself include epilepsy, headaches, dementia (decline of intellect, loss of acquired knowledge and skills, and difficulty learning new ones), and Alzheimer's and Parkinson's diseases. Sleep disorders, depression and anxiety disorders are also closely linked to the nervous system; they should not be considered «simple» problems and require serious attention. Nerve disorders arising from other organs and diseases include secondary nerve disorders associated with cardiovascular and endocrine problems, thyroid problems and diabetes mellitus, especially in older people.
