The nervous system is an extremely complex communication system that can send and receive large amounts of information simultaneously. The nervous system has two distinct parts: the central nervous system (the brain and the spinal cord) and the peripheral nervous system (the nerves located outside the brain and spinal cord). The main unit of the nervous system is neural cells (neurons). The routine work of nerve cells is to increase or decrease the number of connections they have with other neurons. This process may somewhat explain how people learn, adapt, and shape their memories. But the brain and spinal cord rarely produce new neurons. Many people refer to neurologists when they have complicated or very uncommon complications of the brain and the nervous system. Neurologists have expertise in the treatment of all types of brain and nervous system disorders. They, in collaboration with a team of physicians and other professionals, determine the best treatment option according to your needs. They treat the disease by examining the disease. Neurologists, in addition to the complications listed below, also examine people with signs of neurology or complications from other diseases.
