To help diagnose a migraine, your doctor may ask you when your headaches occur, how long they last, and what they feel like.
- Diagnostic Tests for Neurological Disorders
Evaluating and diagnosing damage to the nervous system is complicated and complex. Many of the same symptoms occur in different combinations among the different disorders.
- Effects of Stroke
When an area of the brain is damaged, which typically occurs with a stroke, an impairment may result. An impairment is the loss of normal function of part of the body. Sometimes, an impairment may result in a disability, or inability to perform an activity in a normal way.
Encephalitis is inflammation of the brain. The inflammation causes the brain to swell, which leads to changes in neurological function, resulting in mental confusion and seizures.

- Head Injury
A head injury is a broad term that describes a vast array of injuries that occur to the scalp, skull, brain, and underlying tissue and blood vessels in the head. Head injuries are also commonly referred to as brain injury, or traumatic brain injury (TBI), depending on the extent of the head trauma.
Nearly everyone has suffered from a headache. This article discusses several types of headache, how they are diagnosed and treated.
- History of Stroke
Hippocrates, the father of medicine, first recognized stroke over 2,400 years ago. At this time stroke was called apoplexy, which means "struck down by violence" in Greek.
- Home Page - Nervous System Disorders
The nervous system is a complex, sophisticated system that regulates and coordinates the body's basic functions and activities. It is made up of two major divisions: the central nervous system and the peripheral nervous system.
- How a Migraine Happens
One theory says that migraine pain occurs because of waves of activity by groups of excitable brain cells, which trigger chemicals, such as serotonin to constrict blood vessels.
- Lumbar Disk Disease (Herniated Disk)
Lumbar disk disease occurs when the spongy disks between the vertebrae bulge out or rupture.
Meningitis is inflammation of the membranes that surround the brain. Meningitis can be caused by either a virus or bacteria. Bacterial meningitis may be life-threatening.
- Migraine Headaches
This often severe, throbbing type of headache is different from other types of headaches in that symptoms other than pain occur with the headache. Nausea and vomiting, lightheadedness, sensitivity to light (photophobia), and other visual disturbances are common migraine symptoms.
- Multiple Sclerosis (MS)
Multiple sclerosis is a disease in which the fatty tissue that surrounds the nerves is destroyed. When this happens, the nerves are unable to conduct electrical impulses to and from the brain. It causes muscle weakness, impaired coordination, and fatigue.
- Muscular Dystrophy
Muscular dystrophy causes the muscles in the body to become very weak. The muscles break down and are replaced with fatty deposits over time.
- Myasthenia Gravis
Myasthenia gravis is a chronic, complex, autoimmune disorder in which antibodies destroy neuromuscular connections. This causes problems with communication between nerves and muscle, resulting in weakness of the skeletal muscles. Myasthenia gravis affects the voluntary muscles of the body, especially the eyes, mouth, throat, and limbs.
- Neurocutaneous Syndromes
Neurocutaneous syndrome is a broad term for a group of disorders. These diseases are life-long conditions that can cause tumors to grow inside the brain, spinal cord, organs, skin, and skeletal bones.
- Neurological Disorders
Here is a list of nervous system disorders that require clinical care by a physician or other healthcare professional.
- Neurological Exam
A neurological exam may be performed with instruments, such as lights and reflex hammers, and usually does not cause any pain to the patient.
- Neurological Surgery
Neurological surgery is used to treat disorders of the brain, spine, and nerves. The healthcare provider who specializes in neurological surgery is called a neurosurgeon or neurological surgeon.
Neurology is the branch of medicine that is concerned with the study and treatment of disorders of the nervous system.

A list of online resources to find additional information on nervous system disorders.
- Overview of Nervous System Disorders
Disorders of the nervous system include stroke, infections, such as meningitis, carpal tunnel syndrome, and functional disorders, such as headache and epilepsy.
- Overview of Stroke
Stroke occurs when blood flow to the brain is disrupted. The disruption is caused when either a blood clot or piece of plaque blocks one of the vital blood vessels in the brain or when a blood vessel in the brain bursts.
- Overview of Tests and Procedures for Sleep Disorders
To find out the cause of your sleep problems, your doctor may run a number of tests. These may confirm or rule out various health conditions and other problems.
- Parkinson Disease
Parkinson disease is a motor system disorder that causes trembling, stiffness and trouble moving.
- Primary Sleep Disorders: Dyssomnias
Dyssomnia sleep disorders cause difficulty falling asleep or staying asleep. An example of a dyssomnia is periodic limb movements in sleep.
- Primary Sleep Disorders: Parasomnia
Parasomnias are common sleep disorders that are characterized by strange or bizarre behavior or experiences during sleep.
- Rehabilitation for Neurological Disorders
The goals of a neurological rehab program include helping the patient return to the highest level of function and independence, and improving the overall quality of life—physically, emotionally, and socially.
- Rehabilitation for Stroke
Stroke rehabilitation works best when the patient, family, and rehabilitation staff works together as a team. Family members must learn about impairments and disabilities caused by the stroke and how to help the patient achieve optimal function again.
- Risk Factors for Stroke
The most important controllable risk factor for stroke is controlling high blood pressure. Blood pressure of 140/90 or higher can damage the arteries that supply blood to the brain.
Septicemia is the clinical name for blood poisoning by bacteria. It is a medical emergency and needs urgent medical treatment.
- Signs and Symptoms of Stroke
If you notice any of these symptoms, call 911 or your local emergency medical service immediately. Treatment for stroke is most effective when started as soon as possible.
- Sleep/Wake Cycles
How and when you feel sleepy has to do with your sleep/wake cycles, which are triggered by chemicals in the brain.
- Stages of Sleep
One way that scientists measure sleep is through brain waves, which change in specific ways as you move through the sleep process. Your brain waves change during four basic stages of sleep.
- Statistics of Stroke
Almost every 40 seconds in the United States, a person experiences a stroke.
- Stroke (Brain Attack)

- Topic Index - Nervous System Disorders
Here is a list of the most common types of neurological disorders, including acute spinal cord injury, Alzheimer's disease, epilepsy, and headaches.
- Treatment for Stroke
Although there is no cure for stroke, advanced medical and surgical treatments are now available, giving many stroke victims hope for optimal recovery.
- Types of Muscular Dystrophy and Neuromuscular Diseases
Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue, with or without the breakdown of nerve tissue.
- Types of Stroke
Strokes are classified as either ischemic or hemorrhagic. Ischemic strokes are caused by blockage of an artery. Hemorrhagic strokes are caused by bleeding in the brain.
