Nervous system
There are a lot of things to learn about the nervous system and its associated diseases. The most important thing to know is that there are two types of nervous system in the human body: the first is the central nervous system, which includes the brain and spinal cord, while the second nervous system, , Which contains all the nerves in the body outside the spinal cord and brain, where these two systems communicate with each other to make sure that the body parts can send signals to and from the central nervous system to analyze and send the appropriate reaction to it.
Weak nerves
Neuropathy is a symptom of a particular disease in which a person’s inability to control what he or she wants to do as a result of something has hampered the movement of orders from the brain to the peripheral nerves. The causes of nerve weakness may be the result of a range of neurological disorders, which vary in their causes, symptoms and consequences. The symptoms of nerve damage can vary to include more than 100 types of peripheral disorders affecting the nerves outside the brain and spinal cord, Damage to the complex nerves in the peripheral nervous system is numerous and varied.
Diseases cause nerve weakness
There are many diseases that lead to weak nerves, including congenital and acquired, some cause permanent malfunction and the other temporary, in addition to the large number of neurological diseases of unknown cause, including what is known as spinal injuries or direct injuries to the nerve may directly affect the nerve and challenge Of his job, leading to what is known as weakness of the nerve, and following some diseases accompanied by the presentation of nerve weakness.
Amyotrophic lateral sclerosis
Is a rapidly developing neurodegenerative disease that is always deadly as it attacks nerve cells responsible for controlling voluntary muscles, resulting in weakened muscles and impaired function. It is also called Lou Gehrig, one of the famous tennis players who may be diagnosed with this disease.
Both the upper and lower motor neurons deteriorate or die from the disease. They stop sending messages to the muscles, making them unable to function. The muscles gradually weaken, deteriorate and eventually become paralyzed, and the brain’s ability to start And control of the voluntary movement, and begins the disease involuntary movements involuntary and muscle weakness, and sometimes scattered speech. And ultimately prevents the patient from controlling the muscles necessary for movement and speech and eating and breathing, leading to death, which can not be cured. (ALS):
Symptoms of Amyotrophic Dysplasia:
The symptoms of this disease in its beginnings may be simple and can not be noticed, and increase these symptoms to become more severe over time and the most important:
- Difficulty walking, stumbling or difficulty doing normal daily activities.
- Muscle weakness in one or more of the following: hands, arms, legs or muscles used to speak, swallowing or breathing.
- Difficulty installing the head in a certain position.
- Feeling of tingling or cramping in the muscles, especially those in the hands and feet.
- Weak use of arms and legs.
- The sound is thick and the sound is difficult to produce.
- Dyspnea and difficulty swallowing, in more advanced stages.
Causes and treatment of sclerosis:
The causes of this disease are not fully defined, as only 5-10% of the patients have the disease genetically, while the remaining cases are unknown reason, scientists are studying some of the possible causes of this disease, including:
- Genetic mutations.
- Glutamate is one of the chemical messages in the brain that is toxic to nerve cells.
- Dysfunction of the immune system, inhibition of some neurons.
There is no cure for this disease yet, but some drugs under study are reducing glutamate, as well as supportive treatments to relieve symptoms of the disease and help the patient to rely on himself as much as possible and away from the length of use of artificial respirators of the patient.
Bell’s paralysis
Is a temporary paralysis or weakness in the muscles of one half of the face, and may also affect the sense of taste and the process of decay and the production of saliva, and the disease usually occurs suddenly and gradually disappear on its own gradually over time in a few weeks, and the cause of the disease is unclear to Now, most cases are believed to be caused by the herpes virus causing cold sores. The disease is diagnosed except for all causes of facial paralysis. The results of paralysis are caused by damage or trauma in one of the two facial nerves and is the most common cause of facial paralysis. Bill on only one facial nerve and paired Next to one of the face rarely hits the sides.
Symptoms and treatment of Bell’s paralysis:
The symptoms of Bell’s paralysis are as follows:
- Moving from mild to full paralysis on one side of the face.
- Face drooping and difficulty in using facial expressions.
- Pain around the jaw or in or behind the ear on the affected side.
- Increase the sound sensitivity in the ear of the injured side.
- Headaches.
- Low ability to taste.
- Changes in the amount of tears and saliva that were produced in normal “before injury”.
- Involuntary involuntary movements in the face.
However, the use of certain drugs such as prednisone (corticosteroid) on the first day of the infection relieves many of the symptoms, as well as the need to take care of the eye, and also the use of warm compresses and facial massages to reduce pain.
Bronchitis
It is an inflammation that causes sudden pain in the shoulder and arm followed by weakness and dizziness in them, affecting the motor neurons or some sensory nerves in the shoulder area (brachial plexus), a very rare disease whose cause is unknown or even fully understood.
Symptoms and treatment of bronchitis:
Symptoms of bronchitis include:
- The onset of pain relief has nothing to do with injury in the area.
- Occurrence of piercing, acute, or radiating pain.
- These symptoms come on only one side of the body.
- Severe pain usually lasts for several days, and then the arm muscles weaken in multiple areas.
- Arm weakness may be severe, but usually improves over time.
- Very rarely, in severe cases, the patient may become permanently paralyzed or partially paralyzed in the shoulder muscles a few days after the onset of pain.
The disease is treated with steroids, in addition to powerful painkillers such as morphine and others.
