Nerves
are cylindrical bundles of fibers beginning at the brain and the central cord
and extending to some other part of the body. Major new epidemiological
analyzes focus attention on nervous system disorders as
important causes of death and disability worldwide(Linz et al., 2019). It is composed
of two main divisions including:
·
Central nervous system: It comprises of the spinal cord and
the brain. In addition to the spinal cord and brain, the nervous system's main
organs include: sensory organs of smell, sensory organs of taste, sensory
receptors located in the joints, muscles, skin and other parts of the body.
·
Peripheral nervous system:It comprises of all other neural
elements, including the autonomic nerves and the peripheral nerves.
Functions:
The nervous system controls:
·
The
thinking ability and reason and the nervous system makes you aware and has language, memories and thoughts.
·
Feeling (sensation), smell, taste,
hearing and sight.
·
Involuntary and voluntary functions,
such as balance coordination and movement. Many certain body functions, such as
blood flow and blood pressure, are often controlled by the nervous system.
Causes
and risk factors:
The nervous system is susceptible to
numerous disorders including blood flow, disruption, tumors, structural
defects, degeneration, infections and trauma. Nervous system disorders may
involve in the following things:
Degeneration, such as Alzheimer disease,
Huntington chorea, amyotrophic lateral sclerosis (ALS),multiple sclerosis and Parkinson disease
Functional disorders, such as neuralgia, dizziness,
epilepsy and headache
Vascular disorders, such as extradural hemorrhage, subdural hemorrhage and hematoma, subarachnoid
hemorrhage, transient ischemic attack (TIA) and stroke
Structural disorders, such asGuillain-Barré syndrome,
peripheral neuropathy, spinal cord or brain tumors, carpal tunnel syndrome,
cervical spondylosis, Bell's palsy and spinal cord or brain injury
Infections, such
as epidural abscess, polio, encephalitis and meningitis
Symptoms:
For all the nervous system's
disorders, the most important concern people experience is pain, and most of it
is nervous. Symptoms of a problem with the nervous system depend on which
region of the nervous system is affected and what triggers the issue. Systematic search, Problems with the nervous system
may suddenly occur and cause life-threatening (acute) problems or develop
gradually and induce a progressive (degenerative) loss of function. Symptoms
can be mild or severe. The most common general signs and symptoms of nervous
system disease are as follows. Each person can experience symptoms differently,
however. Symptoms can also include new language impairment (comprehension or
expression), slurred speech and muscle wasting, back pain which radiates to the
toes, feet or other body parts, tremors and seizures, muscle rigidity, lack of
coordination, impaired mental ability, weakness or loss of muscle strength,
memory loss, double vision or Loss of sight, tingling or loss of feeling, a
headache that changes or is different and persistent or sudden onset of a
headache.
Diagnosing:
There are different examinations and
methods for the treatment of nervous system disorders. A specialized X-ray
called a fluoroscopy, in addition to the traditional X-ray, examines the body
in motion, such as blood flowing through arteries. Other standard neurological
exams include a CT scan,electroencephalogram (EEG) and magnetic resonance
imaging (MRI) which records the brain's continuous electrical activity.
Positron emission tomography (PET) is a procedure that measures metabolism and
brain activity of cells or tissues to detect tumors or tissues or tumors(Zimmermann,
2018).
Treatment:
·
Spinal
surgery.
·
Rehabilitation/physical
therapy after brain injury or stroke.
·
Spinal
cord stimulation.
·
Deep
brain stimulation.
·
Medicines,
possibly given by a drug pumps
Prevention:
To keep your body and nervous system
healthy, follow the Guidelines below:
·
Never
smoke or use any other tobacco products.
·
Do
not consume alcohol or unwanted drugs, which may have an effect even long after
use.
·
Limit
the consumption of caffeinated drinks such as colas and coffee that improve
dehydration and can influence sleep.
·
Take
note of health problems that can induce impaired functioning of the nervous
system, such as: high blood pressure, diabetes etc.
·
Do
daily exercise. Speak to the doctor for a workout routine that's going to fit
for you.
·
Drink
abundant water and other liquids. This helps prevent dehydration which can
cause memory and confusion problems.
·
Eat
a healthy diet. A healthy, low-fat diet with adequate foliate sources, vitamin
B6 and B12 can help to strengthen the nervous system. Make sure the food
contains lots of whole grains, vegetables and fruits
Conclusion:
Disorders of the nervous system which
trigger the highest death and disability levels can be treatable and
preventable. Increased awareness of neurological disorders' global effects should help healthcare planners
and the neurological community set adequate research, prevention and management priorities for these conditions.
