There are many disorders of the nervous system that require clinical care from a doctor or other health care professional. We will discuss some of them below.
What is a stroke?
A stroke or brain attack occurs when blood flow to your brain stops. This is an emergency.
The brain needs a constant supply of oxygen and nutrients to function well. If the blood supply is interrupted even for a short time, it can cause problems. Brain cells begin to die after a few minutes without blood or oxygen.
When brain cells die, brain function is lost. You may not be able to do things controlled by this part of the brain. For example, a stroke can affect your ability to:
Move
Speak
Eat
Think
remember
Control your bowels and bladder
Control your emotions
Control other vital body functions.
Strokes can happen to anyone at any time.
What Causes a Stroke?
A stroke occurs when blood flow to the brain is interrupted or impaired.
Alzheimer's disease
Alzheimer's disease is the most common form of dementia, affecting 5.2 million Americans over age 65, as well as hundreds of thousands of people under age 65 with early-onset Alzheimer's.
Nearly two-thirds of Americans with Alzheimer's disease are women.
Alzheimer's disease is diagnosed by ruling out other diseases with similar symptoms, which allows the diagnosis to be made with up to 95 percent accuracy.
Unlike other forms of dementia, Alzheimer's does not affect patients' motor function until the late stages of the disease.
Epilepsy
Epilepsy is a neurological condition involving the brain that causes people to have repeated makes you more prone to seizures. It is one of the most common diseases of the nervous system and affects people of all ages, races and ethnicities. Nearly 2.2 million Americans live with epilepsy.
Anything that disrupts the normal connections between nerve cells in the brain can cause seizures. This includes high fever, low blood sugar, high blood sugar, alcohol or drug use, or concussion. Anyone with this condition can have one or more seizures. However, when a person has two or more seizures, he is considered to have epilepsy. Epilepsy can have many causes, including imbalances in nerve-signaling chemicals called neurotransmitters, tumors, strokes, brain damage from disease or injury, or some combination of these. In most cases, no cause can be found for epilepsy.
