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
- Stance and gait
- Menace response
- Pupil light reflex and symmetry
- 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.
- 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.
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.
