Functional Neurology looks at the underlying functioning of the nervous system. While allopathic neurology can diagnose gross pathology such as a stroke or traumatic brain injury: functional neurology can pinpoint functioning of specific parts of the brain. Such studies include studies with the eyes (saccades (rapid movements from point to point), pupil reflexes) and other neurological assessments. Brain imbalances can be identified long before the pathology points to a specific diagnosis. Once brain imbalances are identified, individualized treatment plans can be prepared to reverse the damages. Periodic assessments can track the improved status of brain in response to treatment. The causes of such brain imbalances can be many such as toxins, infectious process such as lyme disease, metabolic disorders such as blood sugar irregularities and hormone imbalances. It is important to seek and treat the underlying cause as well.
