What is a Nervous System and How Does it Work?
In Health Science, the nervous system is an extremely complex and essential part of any human and animal body that synchronizes our bodily activities by transferring signals to and from the different parts of our body, mainly our mind. Also, it is the nervous system that identifies environmental changes that affect our body, then act on our mind by delivering signals to fight such affecting elements. This entire nervous system has two parts which are mentioned below.

The Central Nervous System: It coordinates our Mind and Spinal Cord.
The Peripheral Nervous System: It included the rest of the nerves in the body, including somatic and autonomic.
Besides your brain, spinal cord and other nerves in the body, the nervous system consists of the following-
- Smooth Muscle
- Cardiac muscle
- Sensory organs (Smell, Taste Buds and visionary)
This is our nervous system, which manages our bodily activities by maintaining our mind and other sensory nerves. Suppose what if your nervous system gets down? It might be a serious threat to your life which shall be taken seriously. Also, identifying nervous system disorders is too simple. Here is an in-depth knowledge of the complex nervous system, disorders, and diseases.
What causes nervous system problems and diseses?
Our nervous system is a sensitive part of our body which can be affected by several serious and mild injuries. Nervous system disorder depends on the damaged areas that cause problems to other areas of the nervous system. These problems may come up gradually which causes constant damage to the system. Or a few may appear abruptly and cause death-dealing diseases, Severe acutes. Here are some serious nervous system disorders and conditions that cause nervous system damage.
Difficulties in Blood Supply (Vascular Disorder)
Serious injuries to the Mind (Head) and Spinal Cord (Trauma)
Inborn Diseases (Congenital Disorder)
Anxiety, Depression, Personality Disorders, Psychotic Disorders (Mental Disorder)
Injuries and Diseases that may cause constant damage to the nervous system (Degenerative)
These are some life-threatening nervous system diseases-
Alzheimer’s Disease- Attack brain function, memory, and behavior.
Bell’s Palsy- Sunnen Weakness and paralyzing facial muscles.
Cerebral Palsy- Hits on the nervous system, muscles, and coordination.
Epilepsy- Serious but rare.
Motor Neurone Disease- Causes muscle weakness.
Multiple Sclerosis- Damages central nervous system.
Amyotrophic Lateral Sclerosis (Lou Gehrig’s disease)- Death of motor neuron due to gradual detoriation.
Parkinson’s Disease– Affects the brain cells.
Huntington’s Disease– Break the parts of brains that cause mental disorders.
Meningitis- Inflamation of meninges of brain and spinal cord.
Paralysis- Loss of muscle function due to detachment of nervous communication.
Encephalitis– Inflamation of brain mostly due to viral infection.
Encephalomyelitis– A demyelinating disease of the brain and spinal cord.
Adrenoleukodystrophy (ALD) – X chromosome linked diorder, which increaes fatty acid depositin on neuron.
Spinal cord injury– Damage to spinal cord can alter the function of peripheral and autonomous nervous system.
Spina bifida– A birth defect due to incomplete closing of the spine and membranes around the spinal cord during early development in pregnancy.
Guillain-Barré syndrome– A autoimmune disease in which immune cells attack self nerve cells.
Multiple system atropy – Neurodgenerative disorder of autonomic nervous system.
The nervous system is efficiently connected to each part of our body, therefore, any damage or injury to any area of the system might reflect in other organs. It may include some serious organ failures and health issues including-
Heart, Liver, Kidney, and Respiratory failure
Over and underactive thyroid
Fluctuated Blood Sugar Level
Infection in Brain
These problems may develop gradually or appear suddenly with the deadliest damage to the nervous system. Here are the symptoms of Nervous System Disorder.
How to Check for Nervous System Problems? Signs and Symptoms of Nervous System Disorders.
Both severe and mild acutes can cause serious nervous system problems. Whether it’s kidney failure or a brain stroke, every disease develops gradually to become life-threatening. Here are some common symptoms of nervous system disorder. However, we all may face these problems and experience the following symptoms.
Here are some major nervous system disorder symptoms and treatments.
Darkness and Dizziness or inactive one side of the body
Burred and low vision suddenly
Hard to speak, chew and trouble any other facial movement
Sharp and sudden Headache
Unable to stand or walk
Nervousness in thinking and doing anything
Nausea and intense vomiting
Petechiae on different body parts
Anxiety Disorder (Fear for no reason)
Lack of Concentration

Sudden unconsciousness is another term and there are several other reasons in the medical term. Also, diabetes and fluctuating blood pressure may cause nervous system disorder. In case of the occurrence of any of the following symptoms, you should avoid self-treatment. The nervous system disorder is a serious health problem that needs to be discussed with the concerned doctor. Neuroradiologists and Interventional Radiologists are related to this.
