Before spotlighting the nervous system disorders, it’ll be very fruitful for you to have a considerable notion of what the nervous system is. So, let’s have a look at its core.
What is the Nervous System?
The nervous system is the segment of an animal’s body that controls and sends signals between different parts of the body. Your nervous system sends signals, or messages, all across your body, using specialized cells known as neurons. The brain, skin, organs, glands, and muscles all send and receive electrical signals.
What are the Parts of the Nervous System?
The central nervous system (CNS) and the peripheral nervous system (PNS) are the two primary elements of the nervous system in vertebrates (PNS).
♦ Central Nervous System
The central nervous system (CNS) is in charge of the majority of bodily and mental activities. It is divided into two sections: the brain and the spinal cord.
♦ Peripheral Nervous System
The PNS is made up primarily of nerves, which are long fibres that connect the CNS to every other part of the body, but it also includes peripheral ganglia, sympathetic and parasympathetic ganglia, and the enteric nervous system, which is a semi-independent part of the nervous system that regulates the gastrointestinal system.
Principal Organs of the Nervous System
The following are the major organs of the nervous system, in addition to the brain and spinal cord:
- Sensory organs of smell
- Sensory organs of taste
- Sensory receptors found in the skin, joints, muscles and other parts of the body
Symptoms of Nervous System Disorders
The most common nervous system disorders symptoms are listed below. Nevertheless, each person may experience symptoms in a unique way. Among the signs and symptoms are:
- Coordination issues
- Seizures, tremors, or muscle rigidity
- Activity, reflexes, or motions change
- Mood or level of consciousness shifts
- Head size excessive growth (or lack thereof)
- Developmental milestones are not met on time.
- Older children may also experience severe headaches, numbness or tingling or vision abnormalities.
What Causes Nervous System Disorders?
Your nerves might be affected by a variety of disorders and ailments. When a nerve is wounded, it has problems delivering messages. It can sometimes be so badly damaged that it is unable to send or receive any messages at all. Nerve damage can result in numbness, pins-and-needles sensations, or discomfort. You may find it difficult or impossible to move the damaged area. Here are some of the most common causes of nerve damage you must be aware of:
When one of the brain’s blood vessels becomes obstructed or explodes, a stroke occurs. A portion of the brain dies because to a lack of blood and causes nervous system problems. Then it won’t be able to convey information through nerves. Nerve damage can range from minor to severe as a result of a stroke.
♦ Accidental Injury
This is another one of the most common causes of nervous system diseases whereby in an accident, nerves might be crushed, twisted, or slashed. Nerve injury can occur anywhere in the body as a result of car accidents and falls.
Diabetic neuropathy is a type of nerve damage caused by an endocrine system disorder. Around 30 million people in the United States have diabetes, and nearly half of them suffer nerve damage. The arms, legs, hands, feet, fingers, and toes are commonly affected by diabetic neuropathy.
When a nerve is squashed or squeezed, it does not receive enough blood to function properly. Nerves can be constricted or blocked for a variety of causes, including overuse, tumors, and structural issues such as sciatica.
♦ Age Factor
Your neurons’ messages may not move as quickly as they formerly did as you get older. Your reflexes may decelerate and you may feel weaker. Some patients lose feeling in their fingers, toes, and other body parts.
Nervous system disorders and diseases can be caused by a variety of infections, cancers, and autoimmune disorders such as diabetes, lupus, and rheumatoid arthritis. Diabetic neuropathy, which causes tingling and pain in the legs and feet, is a side effect of diabetes. Multiple sclerosis is a disease that damages the myelin that surrounds nerves in the central nervous system.
Nervous System Disorders Diagnosis
A nervous system disease can take a long time to diagnose. Our doctors work with patients to identify and eliminate problems before making a diagnosis. This typically entails a series of tests and a thorough examination of the patient’s symptoms. Consistent or sudden onset headaches, loss of feeling or tingling sensations in a specific area of the body, loss of vision or double vision, inadequacy or loss of muscle strength, cognitive impairment or impaired mental ability, muscle rigidity, lack of coordination, tremors or seizures, slurred speech, or back pain that radiates to other parts of the body are all possible symptoms of a nervous system disorder.
Nervous System Diseases Treatment and Prevention
The aim of treatment is to tackle the core cause of a neurological disorders and restore function after the cause has been identified. It’s also critical to take preventative actions wherever possible to lower a patient’s chance of future complications. Of course, treatment is dependent on the exact problem, but we use a multidisciplinary approach. If warranted, drugs, vitamins, nutritional support, spinal manipulation, acupuncture, physical therapy, and lifestyle modifications may all be used to enhance nerve function.
How to Keep Nervous System Healthy?
Your nervous system serves as the brain and control center for the rest of your body. It must be looked after in order for it to continue to function properly. To avoid the severity in neurological disorders consistently see your doctor, maintain a nutritious diet, avoid drugs, and drink alcohol only in moderation. Managing illnesses that can injure your nerves, such as diabetes, is the greatest strategy to avoid nerve damage from disease.
