Neurological disorders may often be caused by the following factors:

  • Genetic Disorders
  • Congenital Abnormalities
  • Infections
  • Brain Injuries

Types of Neurological Disorders


Caused by damage to the nerves located outside the brain and spinal cord, it can affect motor functions and other bodily functions like digestion and urination. The condition can occur as a result of diabetes, medication, traumatic injuries, infections, metabolic problems or inherited causes. The disorder is characterised by these symptoms:

    • Slowing Movement


It is the medical condition where blood supply to a part of the brain is cut off.
