Disorders Of The Nervous System: Causes, Symptoms & Treatment

In human body the nervous system is considered to be a master control unit, as every minor or major activity and function is controlled by it. The nervous system is made up of complex and intricate network of nerve fibers. This complex system is divided into two major divisions, the central nervous system consisting brain and spinal cord and peripheral nervous system which consists of peripheral and autonomic nerves.

Both the divisions work hand in hand to perform voluntary and involuntary functions of various organs of body. With any damage or disorder to the nervous system, your body will not be able to function properly.

There are numerous nerve disorders which may be caused due to trauma, infection, genetic abnormality, degeneration etc. Let us review some important neurological diseases that hamper and disable a person’s daily life.

What Are Some Causes Of Nervous System Disorders?

Neurological disorders can be caused due to various reasons such as:

  • Infections: Infection due to bacteria, viruses, parasites can cause conditions such as meningitis, encephalitis, brain abscess, spinal tuberculosis, etc.
  • Vascular disorders: This is related to damage or dysfunction of blood vessels that supply blood to the nervous system. Hemorrhage, ischemia resulting in stroke.
  • Structural abnormality: The abnormality can arise during development of nervous system in the womb or it may develop later in life.
    Spinabifida is deformity of spine that occurs since birth. Other occurring later in life includes lumbar and cervical spondylosis, herniated disc, tumors in brain and spinal cord, peripheral neuropathy etc.
  • Abnormal functioning: Headache, epilepsy, seizures, dizziness, etc.
  • Degeneration: Degeneration of brain cells can cause diseases such as Parkinson’s disease, multiple sclerosis, Alzheimer’s disease etc.
  • Many other problems affect normal functioning of nervous system such as alcohol intoxication, electrolyte imbalance, deficiency of vitamin B12 and B1, low blood sugar, etc.

Symptoms Of Nervous System Disorders
