“Huntington’s disease is a hereditary, degenerative brain disease that leads to uncontrolled movements, intellectual/cognitive decline, and emotional problems. Someone with a parent who has Huntington’s disease has a 50 percent chance of inheriting the gene for the disease.”

“Stages of Sleep and Sleep Cycles. Usually sleepers pass through four stages: 1, 2, 3, and REM (rapid eye movement) sleep. These stages progress cyclically from 1 through REM then begin again with stage 1. A complete sleep cycle takes an average of 90 to 110 minutes, with each stage lasting between 5 to 15 minutes.”

“ALS was first found in 1869 by French neurologist Jean-Martin Charcot, but it wasn’t until 1939 that Lou Gehrig brought national and international attention to the disease. Ending the career of one of the most beloved baseball players of all time, the disease is still most closely associated with his name. Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord.”

“The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring.”

NIH Eunice Kennedy Striver National Institute of Child Health and Human Development.

The nervous system is a complex, sophisticated system that regulates and coordinates body activities. It is made up of two major divisions, including the following:

• Central nervous system. This consists of the brain and spinal cord.
• Peripheral nervous system. This consists of all other neural elements, including the peripheral nerves and the autonomic nerves.

In addition to the brain and spinal cord, principal organs of the nervous system include the following:

• Eyes
• Ears
• Sensory organs of taste
• Sensory organs of smell
• Sensory receptors located in the skin, joints, muscles, and other parts of the body

What are some disorders of the nervous system?

The nervous system is vulnerable to various disorders. It can be damaged by the following:

• Trauma
• Infections
• Degeneration
• Structural defects
• Tumors
• Blood flow disruption
• Autoimmune disorders

Disorders of the nervous system

Disorders of the nervous system may involve the following:

• Vascular disorders, such as stroke, transient ischemic attack (TIA), subarachnoid hemorrhage, subdural hemorrhage and hematoma, and extradural hemorrhage
• Infections, such as meningitis, encephalitis, polio, and epidural abscess
• Structural disorders, such as brain or spinal cord injury, Bell’s palsy, cervical spondylosis, carpal tunnel syndrome, brain or spinal cord tumors, peripheral neuropathy, and Guillain-Barré syndrome
• Functional disorders, such as headache, epilepsy, dizziness, and neuralgia
• Degeneration, such as Parkinson disease, multiple sclerosis, amyotrophic lateral sclerosis (ALS), Huntington chorea, and Alzheimer disease

Signs and symptoms of nervous system disorders

The following are the most common general signs and symptoms of a nervous system disorder. However, each individual may experience symptoms differently. Symptoms may include:

• Persistent or sudden onset of a headache
• A headache that changes or is different
• Loss of feeling or tingling
• Weakness or loss of muscle strength
• Sudden loss of sight or double vision
• Memory loss
• Impaired mental ability
• Lack of coordination
• Muscle rigidity
• Tremors and seizures
• Back pain which radiates to the feet, toes, or other parts of the body
• Muscle wasting and slurred speech

The symptoms of a nervous system disorder may resemble other medical conditions or problems. Always consult your healthcare provider for a diagnosis.

Healthcare providers who treat nervous system disorders

Healthcare providers who treat nervous system disorders may have to spend a lot of time working with the patient before making a probable diagnosis of the specific condition. Many times, this involves performing numerous tests to eliminate other conditions, so that the probable diagnosis can be made.

Neurology. The branch of medicine that manages nervous system disorders is called neurology. The medical healthcare providers who treat nervous system disorders are called neurologists.

Neurological surgery. The branch of medicine that provides surgical intervention for nervous system disorders is called neurosurgery, or neurological surgery. Surgeons who operate as a treatment team for nervous system disorders are called neurological surgeons or neurosurgeons.

Rehabilitation for neurological disorders. The branch of medicine that provides rehabilitative care for patients with nervous system disorders is called physical medicine and rehabilitation. Healthcare providers who work with patients in the rehabilitation process are called physiatrists.

“High blood pressure is the biggest contributor to the risk of stroke in both men and women. Monitoring blood pressure and, if it is elevated, treating it, is probably the biggest difference women can make to their vascular health.”

Dr. Rost – Harvard Medical School

“If someone shows any of these symptoms, immediately call 9-1-1 or emergency medical services.  the sooner the addressed the better results for many patients”

American Stoke Association

“Stroke is the leading cause of serious, long-term disability in the United States. Each year, approximately 795,000 people suffer a stroke.”
