Neurological Disorders Symptoms

Neurological disorders involve diseases, conditions, and infections of the central nervous system, which includes the brain, spinal, cord, and peripheral nerves. There are 12 common neurological disorders that have been studied and surveyed by NCBI.

  • Autism – affects 5.8 children out of 1,000
  • Cerebral Palsy – affects 2.4 children out of 1,000
  • Tourette Syndrome – insufficient data
  • Migraine – affects 121 individuals out of 1,000
  • Alzheimer’s Disease – affects 67 elderly individuals out of 1,000
  • Parkinson’s Disease – affects 9.5 elderly individuals out of 1,000
  • Epilepsy – affects 7.1 individuals out of 1,000
  • CVA (stroke) – affects 183 individuals out of 100,000
  • Major Traumatic Brain Injury – affects 101 individuals out of 100,000
  • ALS – affects 1.6 individuals out of 100,000


  • Autism – Difficulty relating and communicating with others. Impaired cognitive function and flexible behavior.
  • Cerebral Palsy – impaired motor skills, poor muscle tone, poor body balance, speech impediments, dysphagia (difficulty swallowing), and tardive dyskinesia (abnormal, involuntary movements).
  • Tourette Syndrome – tardive dyskinesia, facial grimacing, sniffing, twisting, throat clearing, and echolalia (repetitive speaking).
  • Migraine – pulsating, throbbing headache, with unilateral head pain, nausea, vomiting, blurred and halo vision, dizziness, and sometimes fainting.
  • Alzheimer’s Disease – slow declining memory loss with the inability to reason. Short-term memory is the first to go, followed by long-term memory loss.
  • Parkinson’s Disease – hand tremors, bradykinesia (slow movement), poor motor skills, speech impairments, and impaired posture.
  • Epilepsy – temporary confusion, uncontrolled staring, full body tremors, loss of consciousness, and psychic symptoms.
  • CVA – numbness and weakness of the leg, arm, or face, which is often unilateral. Blurred vision, poor motor skills, poor balance, double vision, dysarthria (difficulty speaking) and confusion.
  • Major Traumatic Brain Injury – headache, dizziness, dysarthria, confusion, unconsciousness, amnesia (beginning immediately before and 24 post injury), nausea, and vomiting.
  • ALS – poor motor skills and balance, dysarthria, muscle cramps, arm and tongue tremors, weakness in legs, feet, and ankles (bilateral).
