Neurology on the internet

Since the Internet's inception in 1969, neurologists have witnessed a continuous parade of innovative phases. There is tremendous potential for near-instantaneous dissemination of the latest developments in neurologic knowledge, although their value is dependent on the degree of awareness of neurologists and is limited by the reluctance of some sources to make information readily accessible. The encyclopedic nature of the Internet, with its vast resources of online information, may be diminished by issues of access, variable quality and reliability, and a lack of intelligent retrieval systems. A major hindrance, for example, is seen with restrictions on archival, but proprietary, neurologic literature. Neurologic patients and their caregivers use the Internet heavily, but for somewhat different reasons. It is important for neurologists to understand these differences. The emergence of the online Personal Health Record will become increasingly valuable as these sites evolve and more medical providers incorporate electronic applications and medical records into their practices. Online groups for neurologists with similar interests, often referred to as "networks," have the potential to catalyze the natural organizing tendencies among those seeking solutions to shared problems. Networking can function well for neurologists, neurologic patients, and for focused efforts in an area such as advocacy. These considerations are discussed in this article.
