Multiple Sclerosis means a definite Diagnosis of at least one of the following:
- Two or more separate clinical attacks, confirmed by a magnetic resonance imaging (MRI) of the nervous system, showing multiple lesions of demyelination;
- A single attack, with objective neurological deficits lasting more than 6 months, confirmed by MRI of the nervous system, showing multiple lesions of demyelination; or
- A single attack, confirmed by repeated MRI of the nervous system, which shows multiple lesions of demyelination which have developed at intervals at least one month apart.
The Diagnosis of Multiple Sclerosis must be made by a Specialist.
For purposes of the group policy, neurological deficits must be detectable by a Specialist and may include, but are not restricted to, measurable loss of hearing, measurable loss of vision, measurable changes in neuro-cognitive function, objective loss of sensation, paralysis, localized weakness, dysarthria (difficulty with pronunciation), dysphasia (difficulty with speech), dysphagia (difficulty swallowing), impaired gait (difficulty walking), difficulty with balance, lack of co-ordination, or new-onset seizures undergoing treatment. Headache or fatigue will not be considered a neurological deficit.
