Neurology is a branch of medicine dealing with disorders of the nervous system. It deals with the diagnosis and treatment of all conditions and disease involving the central and peripheral nervous system including their coverings, blood vessels, and all effector tissue, such as muscle.
Current Clinical Trials Related to Neurology
A migraine is a primary headache disorder characterized by recurrent headaches that are moderate to severe. Typically, the headaches affect one half of the head, are pulsating in nature, and last from two to 72 hours. Associated symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell. The pain is generally made worse by physical activity. Up to one-third of people have an aura: typically a short period of visual disturbance which signals that a headache will soon occur.
“Painful” doesn’t even begin to describe cluster headaches for many. Cluster headaches are fierce, intense headaches that happen in “clusters” that often last for 6 to 12 weeks. They occur on the side of the head, usually around the eye. People who have cluster headaches can seek help from doctors, specialists, and other options, but the headaches often come back.
Other Types of Diseases Related to Neurology
Stroke is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of vision to one side.
Epileptic seizures are the result of excessive and abnormal nerve cell activity in the cortex of the brain. The diagnosis involves ruling out other conditions that might cause similar symptoms such as fainting and determining if another cause of seizures is present such as alcohol withdrawal or electrolyte problems. This may be partly done by imaging the brain and performing blood tests. Epilepsy can often be confirmed with an electroencephalogram (EEG), but a normal test does not rule out the condition.
