A neurological disorder is any disorder of the body nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness. Neurology is a medical specialty dealing with disorders of the nervous system. Specifically, it deals with the diagnosis and treatment of all categories of disease involving the central, peripheral, and autonomic nervous systems, including their coverings, blood vessels, and all effected tissue, such as muscles.
Physicians who specialize in neurology are called neurologists, and are trained to investigate, or diagnose and treat, neurological disorders. Although many mental illnesses are believed to be neurological disorders affecting the central nervous system, traditionally they are classified separately, and treated by psychiatrists.
Neurological symptoms are symptoms caused by, or occurring in, the nervous system. The nervous system consists of two anatomic parts.
When these connections are disrupted, neurological symptoms occur.
There are over 600 known neurological disorders and conditions that affect the human nervous system and for many of them treatment options are extremely limited. In addition to the physical and mental toll these conditions take on patients, their families and caregivers, they also have an enormous economic impact, resulting in hundreds of billions of dollars annually in medical expenses and lost productivity.
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, including the central nervous system (consisting of the brain and spinal cord) and the peripheral nervous system (consisting of all other neural elements). Neurological disorders include diseases of the central and peripheral nervous system such as,
These disorders include;
In addition, there are a number of diseases that attack the nervous system itself. They include;
Neurological disorders are common and can be life-threatening, like brain tumors and strokes, or less harmful (though potentially debilitating), like tension headaches and sleep disorders.
Cat Ownership Not Linked To Mental Health Problems - New research reveals no link between cat ownership and psychotic symptoms, contrary to a belief that people who grew up with cats were at higher risk of mental illness.
