Individuals with multiple sclerosis (MS) face more than double the suicide risk compared to the general population. This elevated risk persists for over 20 years post-diagnosis and has not decreased since 1953.

Area of Science:

  • Neurology
  • Epidemiology
  • Public Health

Background:

  • Multiple sclerosis (MS) is a chronic neurological disease with significant physical and psychological impacts.
  • Understanding the mental health burden, specifically suicide risk, in MS populations is crucial for patient care and support.

Purpose of the Study:

  • To compare suicide risk in Danish citizens diagnosed with multiple sclerosis against the general population.
  • To analyze trends and changes in suicide risk among MS patients over a 45-year period.

Main Methods:

  • Utilized data linkage between the Danish Multiple Sclerosis Registry and the Cause of Death Registry.
  • Included 10,174 individuals diagnosed with MS between 1953 and 1996, with follow-up until January 1999.
  • Calculated standardized mortality ratios (SMRs) based on time since diagnosis, age, and calendar period.

Main Results:

  • The overall suicide risk for individuals with MS was more than double that of the general population (SMR = 2.12).
  • A significantly higher risk was observed in the first year post-diagnosis (SMR = 3.15).
  • The excess suicide risk remained elevated, even more than 20 years after diagnosis.

Conclusions:

  • Individuals with multiple sclerosis exhibit a substantially higher risk of suicide compared to the general population.
  • This increased suicide risk is a long-term concern, persisting for decades after diagnosis.
  • There has been no observed decline in this excess suicide risk since 1953, highlighting a persistent public health issue.
