Prognosis
Our Structure
Multiple Sclerosis (MS) is not considered a fatal condition, but it is a progressive and degenerative disease, especially if left untreated or poorly managed. Many people with MS live long and fulfilling lives, particularly when they have access to effective treatments and make healthy lifestyle changes. Life expectancy for people with MS in New Zealand continues to improve, thanks to advances in diagnosis, treatment, and a better understanding of the benefits of a healthy lifestyle.
On average, a person with MS in New Zealand can expect to live about 7–10 years fewer than someone without MS. Recent research found a median life expectancy of 79.4 years for people with MS, compared to 86.6 years for the general population-a gap that is narrowing as treatments improve. MS is unpredictable, with the type, frequency, and severity of symptoms varying greatly between individuals.
Disease Course and Progression
Below are the most common symptoms experienced by people with MS. Click or tap each section for more information:
Relapsing Remitting MS (RRMS)
About 88% of people are initially diagnosed with RRMS. Up to 80% may eventually develop secondary progressive MS (SPMS) over time
Progressive MS
Around 12% are diagnosed with a progressive form from the start. Disability tends to progress more rapidly in these cases, but the rate and pattern are highly individual. For example, a quarter of people with primary progressive MS may require a walking aid within 7.5 years, while another quarter may not need one after 25 years
Relapses
There is no way to predict the timing or frequency of relapses. Some people may go years or even decades without a relapse. Most relapses do not cause permanent disability, especially when followed by recovery and appropriate managemen
