The nerves are the communication lines of the human body. Nerves have to work efficiently to ensure that message is transported throughout the body for the organs to function correctly. In some instances, nerves become diseased or damaged or do not work properly, although if the nerve structure is intact, This leads to impaired communication from the specific parts of the body. Nerves are made of bundles of fibers; these are made up of nerve cells called neurons.
The brain and spinal cord are considered the nerve control center of the body. Signals that are carried away from the brain or the spinal cord to the other parts of the body are called Efferent Nerve fibers, whereas the signals sent from other parts of the body to the brain or the spinal cord are called Afferent nerve fibers. Some nerves may have both afferent and efferent fibers. Weak nerves are usually defined as nerve dysfunction, which means that the nerves are diseased or damaged in some way or cannot function properly.
As a result, nerve signals cannot be transmitted along the nerve. If a motor nerve is affected, then the movement of the body part concerned with the nerve is not able to move properly; if a sensory nerve gets affected, the sensation of the body part gets impaired. Nervous weakness is also sometimes used to describe mental health conditions where anxiety and nervousness are common symptoms.
Causes of Nervous Weakness:
- Nerve gets inflamed
- Compression of the nerve or pinched nerve
- Injury to the nerves
- Degeneration of the nerves
- Erosion or damage to the insulating layer of the nerves.
- Disturbances of the neurotransmitters
- Invasion of the healthy nerve cells due to malignant tumors
- Nerve impulses get disrupted due to toxins
Symptoms of Nervous Weakness:
1. Sensory Symptoms: These symptoms include burning sensation, aching, pain, tingling, prickling, diminished vision, smell, touch, hearing, and taste.
2. Motor Symptoms: These symptoms include muscle weakness, muscle wasting, paralysis, tremors, and poor coordination.
Other Symptoms may depend on the criticality of the disease. Factors that are to be considered are that almost all the nerves are connected to the brain; due to the number of nerves and complexity of connections, problems of the nerves in the brain can show symptoms of memory problems, learning, and cognitive difficulties impaired sensation, etc.
