Diagnostic Tests For Brain And Nerve Disorders

When we carry out a neurological examination we do specific tests examining therse discrete activities:

  • Mental status
  • Head posture
  • Coordination
  • Circling
  • Stance and gait
  • Attitude
  • Menace response
  • Pupil light reflex and symmetry
  • Nystagmus
  • Facial muscle expression and symmetry

These pinpoint sites of possible damage or disease. We may need additional information such as:

  • BLOOD ANALYSIS
    Routine blood chemistry and hematology identify organic disease such as liver failure that may cause neurological signs.
  • ELECTROENCEPHALOGRAM - EEG
    An EEG identifies changes in the electrical activity of the brain that may be related to seizures or tumours.
  • BRAINSTEM AUDITORY EVOKED RESPONSE - BAER
    This test monitors electrical changes in the brainstem and is useful for examining that area, particularly its ability to process hearing messages from the ears. We do not carry out this testing at the clinic as it is so specialised, a referral to one of the specific BAER Hearing Test Centres is needed.
  • CEREBROSPINAL FLUID (CSF) ANALYSIS
    A needle is inserted into the spinal canal and fluid is collected. Changes occur with infection, inflammation and tumours. CSF pressure changes give clues to the presence of obstructions.
  • X-RAYS
    Plain x-rays reveal bone and cartilage damage and loss of symmetry. Contrast x-rays, called a myelogram outline the spinal cord. There is risk associated with contrast spinal x-rays
  • SCANS - CT and MRI
    These are the most revealing diagnostic aids, the best aids for examining the brain itself. Scans are conducted by the neurology specialists at Dick White Referrals.
