Arachnoid Cysts
Arachnoid cysts are cerebrospinal fluid-filled sacs that may develop between the surface of the brain and the cranial base or on the arachnoid membrane - one of the 3 membranes that cover the brain and the spinal cord. Most cases begin during infancy, however onset may be delayed until adolescence.
Arteriovenous Malformation (AVM)
An arteriovenous malformation (AVM) is a congenital disorder characterized by a complex, tangled web of arteries and veins. An AVM may occur in the brain, brainstem, or spinal cord and is caused by abnormal development of blood vessels. The most common symptoms of AVM include hemorrhaging, seizures, headaches, and neurological problems such as paralysis or loss of speech, memory, or vision.
Brain Basics: Preventing Stroke
Stroke ranks as the third leading killer in the United States. A stroke can be devastating to individuals and their families, robbing them of their independence. It is the most common cause of adult disability. Each year more than 700,000 Americans have a stroke, with about 160,000 dying from stroke-related causes.
Central Pain Syndrome
Central pain syndrome is a neurological condition caused by damage to or dysfunction of the central nervous system (CNS), which includes the brain, brainstem, and spinal cord. This syndrome can be caused by stroke, multiple sclerosis, tumors, epilepsy, brain or spinal cord trauma, or Parkinson's disease.
Chiari Malformation
Arnold-Chiari Malformation is a condition in which the cerebellum portion of the brain protrudes into the spinal canal. It may or may not be apparent at birth.
Chronic Pain
While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different. Chronic pain persists. Pain signals keep firing in the nervous system for weeks, months, even years.
Encephalitis and Meningitis
Encephalitis and meningitis are inflammatory diseases of the membranes that surround the brain and spinal cord and are caused by bacterial or viral infections. They can both cause headaches.
Epilepsy
Epilepsy is a brain disorder in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormally. In epilepsy, the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness.
Fibromyalgia
Fibromyalgia syndrome is a common and chronic disorder characterized by widespread muscle pain, fatigue, and multiple tender points. The word fibromyalgia comes from the Latin term for fibrous tissue (fibro) and the Greek ones for muscle (myo) and pain (algia).
Know Stroke. Know the Signs. Act In Time.
Stroke is the third leading cause of death in the United States and a leading cause of serious, long-term disability in adults. About 600,000 new strokes are reported in the U.S. each year. The good news is that treatments are available that can greatly reduce the damage caused by a stroke. However, you need to recognize the symptoms of a stroke and get to a hospital quickly.
The Life and Death of a Neuron
For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.
Lupus Erythematosus
Lupus is one of many disorders of the immune system known as autoimmune diseases. In autoimmune diseases, the immune system turns against parts of the body it is designed to protect. This leads to inflammation and damage to various body tissues.
Occipital Neuralgia
Occipital neuralgia is a chronic pain disorder caused by irritation or injury to the occipital nerve located in the back of the scalp. Individuals with the disorder experience pain originating at the nape of the neck. The pain, often described as throbbing and migraine-like, spreads up and around the forehead and scalp.
Pain: Hope Through Research
Today, scientists understand a great deal about the causes and mechanisms of pain, and research has produced improvements in the diagnosis and treatment of a number of painful disorders. Research offers a powerful weapon in the battle to prolong and improve the lives of people with pain: hope.
Paroxysmal Hemicrania
Paroxysmal hemicrania is a rare form of headache that usually begins in adulthood. Patients experience severe throbbing, claw-like, or boring pain usually on one side of the face; in, around, or behind the eye; and occasionally reaching to the back of the neck.
Pseudotumor Cerebri
Pseudotumor cerebri literally means "false brain tumor." It is likely due to high pressure caused by the buildup or poor absorption of cerebrospinal fluid in the subarachnoid space surrounding the brain.
Stroke
A stroke happens when blood flow to the brain stops. There are two different kinds of stroke. The most common is an ischemic stroke, caused by a blood clot that blocks a blood vessel or artery in the brain. The other, less common, is a hemorrhagic stroke, caused when a blood vessel in the brain ruptures and spills blood into the surrounding tissue.
Stroke: Hope Through Research
Brain damage begins from the moment the stroke starts and often continues for days afterward. Scientists now know that there is a very short window of opportunity for treatment of the most common form of stroke. Because of these and other advances in the field of cerebrovascular disease stroke patients now have a chance for survival and recovery.
Transient Ischemic Attack
A transient ischemic attack (TIA) is a transient stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long.
Traumatic Brain Injury
Traumatic brain injury (TBI) occurs when a sudden physical assault on the head causes damage to the brain. The damage can be focal, confined to one area of the brain, or diffuse, involving more than one area of the brain. TBI can result from a closed head injury or a penetrating head injury.
Trigeminal Neuralgia
Trigeminal neuralgia, also called tic douloureux, is a condition that affects the trigeminal nerve (the 5th cranial nerve), one of the largest nerves in the head. The trigeminal nerve is responsible for sending impulses of touch, pain, pressure, and temperature to the brain from the face, jaw, gums, forehead, and around the eyes.
Vasculitis including Temporal Arteritis
Vasculitis is an inflammation of the blood vessel system, which includes the veins, arteries, and capillaries. Vasculitis may affect blood vessels of any type, size, or location, and therefore can cause dysfunction in any organ system, including the central and peripheral nervous systems.
