Vertigo and disorders of balance
Advice on health categories
Studies of inner ear vestibular function or disorders are classified as Ear.
Other studies of balance, dizziness and vertigo involving a specific central nervous component should be classified as Neurological.
If there is a specific cognitive/perceptual aspect it may be appropriate to classify as Mental Health.
Main inclusion criteria
Dementias, transmissible spongiform encephalopathies, Parkinson’s disease, neurodegenerative diseases, Alzheimer’s disease, epilepsy, multiple sclerosis and studies of the normal brain and nervous system.
Advice on health categories
This category is suitable for studies of the ‘wiring’ of the brain.
Includes studies of TSEs, CJD and prion protein.
Studies on circadian rhythm are often but not always Neurological.
Other conditions where disruption to circadian rhythm is linked to disease should be coded to the appropriate health category. For example, circadian influence on immune cells in rheumatoid arthritis would be coded as Inflammatory and Immune System.
Studies on headaches and migraine are often but not always Neurological.
Headaches resulting from other conditions may require alternative or additional health categories, following the rules for sequelae. For example, headaches resulting from visual impairments can be coded 50% Eye, 50% Neurological.
Studies of the Blood-Brain Barrier, vascular cognitive impairments and vascular dementia should be coded as Neurological unless there is significant additional emphasis on either circulation (50% Cardiovascular, 50% Neurological) or the blood flow to the brain (50% Neurological, 50% Stroke).
Excludes studies dealing with the brain of individuals with a psychological condition listed in the Mental Health category which should be coded as 100% Mental Health.
