Nervous system and common nervous system problems
Nervous disorders such as multiple sclerosis, Alzheimer's disease, Parkinson's disease, epilepsy and stroke, can affect your memory and ability to perform daily activities. Let's learn about the structure of the nervous system and neurological disorders in the following article.
1. Types of nerves in the body
There are three types of nerves in the body are autonomic nerves, which control involuntary or voluntary activities of the body including heart rate, blood pressure, digestion and temperature regulation. . Autonomic nerves carry information about the body and the external environment to internal organs, such as: blood vessels, stomach, intestines, liver, kidneys, and bladder. In response to this information, autonomic nerves stimulate or inhibit the organs they supply. These nerves function automatically (autonomously) without a person's conscious effort. In the case of autonomic nerve damage or disorders of the autonomic nervous system, the organ they regulate may malfunction.
The second type of nerve is the motor nerve, which controls movements and actions by transmitting information from the brain and spinal cord to the muscles. Motor nerves carry impulses that control muscle movement from the brain through the spinal cord to the muscles. If the motor nerve is damaged, the muscles can become weak or paralyzed.
The third type of nerve is the sensory nerve, which carries information from the skin and muscles back to the spinal cord and brain. If the sensory nerves are damaged, the body may not be able to perceive abnormal sensations or vision and other senses may be impaired or even lost. The nerves connect the spinal cord to the rest of the body, including 31 pairs of spinal nerves
2. Neurological disorders and typical symptoms
Neurological disorders are disorders that affect the brain, spinal cord, and nerves. Symptoms of neurological disorders can affect part or all of the nervous system. The degree of influence can vary because the nervous system controls so many different functions in the body. Symptoms of neurological disorders are diverse from headache, back pain, muscle pain to vision, taste, smell and hearing disturbances. Nervous disorders can interfere with sleep, causing anxiety or excitement before bedtime leading to fatigue and daytime sleepiness. The severity of neurological symptoms can be as mild as somnolence or can be life-threatening such as coma from a stroke.
The following are some relatively common neurological symptoms:
Types of pain: Back pain, neck pain, headache, pain along the nerve path (such as sciatica or shingles) Feeling weak: Tremor, paralysis Involuntary movements: Poor coordination, muscle spasms, stiffness and spasticity, slowed movement Sensory changes: Numbness, tingling or prickling sensations, increased sensitivity with light touch, loss of sensation to cold, heat or pain Changes in special senses: Disorders of smell and taste, visual hallucinations, partial or complete loss of vision, double vision, deafness, Tinnitus . Other symptoms: Dizziness, loss of balance, difficulty swallowing, slurred speech. Sleep problems: trouble falling asleep, uncontrolled leg movements while sleeping, uncontrollable dozing or sleeping too much Changes in consciousness: Fainting, confusion or delirium, seizures, coma Changes in perception: Difficulty understanding language or using language to speak or write, poor memory, difficulty with ordinary motor skills, inability to recognize familiar objects or faces familiar.
