If a general practitioner suspects that a patient is suffering from a neurological condition, he or she may refer the patient to a neurologist. Alzheimer's disease, diabetic neuropathy, migraines, and nerve damage are all examples of neurological problems. A neurologist has special training in diagnosing diseases and disorders of the brain and nervous system. A neurologist can help diagnose many different conditions that may first appear to be medical problems but are actually caused by issues with the brain such as multiple sclerosis (MS), Parkinson's disease, and dementia. These professionals can also help treat patients who suffer from neurological disorders; for example, a neurologist may prescribe medications to reduce pain or control symptoms associated with MS. Neurologists receive additional training in areas such as psychiatry, neurosurgery, neuromuscular medicine, and rehabilitation. Because of this specialization, they are able to provide advice on how best to care for patients who suffer from neurological problems. General practitioners (GPs) are doctors who have completed their residency training and can practice medicine in any specialty. They provide primary care to individuals who do not require a specialist because there is no other physician available within the community. GPs work within a hospital or clinic setting and usually have a team of assistants that help them with tasks such as examining patients, writing prescriptions, and reporting test results to secondary providers.
