Comorbidities (when someone is living with more than one condition) are common in MS and can affect people at the onset of their disease, and are even more prevalent in the aging MS population. Evidence presented at the 7th Joint ECTRIMS/ACTRIMS meeting in Paris, France on October 24-28, 2017 by Dr. Ruth Ann Marrie (University of Manitoba) suggests that comorbidities are associated with a negative impact on outcomes including an increase in disability progression, hospitalizations, mortality and a change in response to fatigue management. Aging is associated with certain comorbidities in the general population, and is no different in people living with chronic conditions such as MS. The most common comorbidities for people with MS were diabetes, heart disease, hypertension (high blood pressure), hyperlipidemia (high cholesterol) and peripheral vascular disease. In the aging MS population, comorbidities may appear at a time when disability progression is increasing and management of the disease is more challenging.
According to a separate Canadian study, the number of people living with MS over the age of 55 is increasing. It is postulated that this is due to improved quality of life of patients and the availability of more effective treatments for MS.
As people living with MS age, the risk of certain comorbidities increases. The need for multi-disciplinary, patient-centred care for prevention and treatment of comorbidity in people living with MS is critical in the overall management of the disease, especially within the aging MS population.
