Neurological disorders associated with 80% higher suicide rate: JAMA
Denmark: Neurological disorders confer increased suicide risk to the patients afflicted by them. Neurological disorders have been linked to suicide, but the risk across a broad spectrum of neurological disorders remains to be assessed. The prevalence of neurological disorders is increasing, along with accompanying considerable morbidity.
Researchers conducted a study to examine whether people with neurological disorders die by suicide more often than other people and to assess temporal associations. They have found that patients with neurological disorders have an 80% higher suicide rate compared with unaffected individuals. The researchers conducted a Danish nationwide retrospective cohort study in which 7,300,395 individuals age 15 years or older were included between1980-2016. The main outcome was death by suicide during a median 23.6-year follow-up.
The researchers found that-
Suicide rate per 100,000 person-years:
44.0 with a neurological disorder diagnosis vs 20.1 without a neurological disorder diagnosis.
Adjusted incidence rate ratio for individuals with vs without neurological disorder diagnosis: 1.8 (95% CI, 1.7-1.8).
Ratio (95% CI) by disorder:
4.9 (3.5-6.9) for amyotrophic lateral sclerosis,
4.9 (3.1-7.7) for Huntington's disease,
2.2 (1.9-2.6) for multiple sclerosis,
