Lyme disease and risk of suicidal behaviour suicidal adfærd

We will examine the risk of suicidal behavior associated with Lyme disease. We will look into how this risk is according to age of infection with Lyme, number of infections, days hospitalized due to Lyme disease and time since Lyme disease.

Traumatic brain injury (TBI) and risk of suicidal behaviour

We found that the risk of suicide is almost twice as high in people who experienced a TBI compared with people who had no TBI records. The risk was especially high in the first period after the TBI incident and oncreased by number of experienced TBI’s.

Genetics of suicide attempts in individuals with and without mental disorders

Family studies shown an aggregation of suicidal behaviour in families. The aim of this study was to conduct a genome-wide association study (GWAS) and estimate single nucleotide polymorphisms (SNP) heritability for suicide attempt in a national sample of individuals with and without mental disorders. This is the largest sample investigated to date, significant SNP associations to suicide attempt were identified. The findings furthermore indicated that genetic transmission of suicide attempt is not solely explained by diagnosed mental disorders.
The study was published in Molecular Psychiatry.
The project was funded by the iPSYCH-grant from the Danish Lundbeck Foundation

Infections and suicide

Findings suggest that infections might be linked to the development of psychiatric disorders and suicidal behaviour. To estimate the association between hospitalization with infection and the risk of death by suicide. An increased risk of death by suicide was found among individuals hospitalized with infection in prospective and dose-response relationships. These findings indicate that infections may have a relevant role in the pathophysiological mechanisms of suicidal behaviour.
The study was published in JAMA Psychiatry.
The project has received support from the Lundbeck Foundation.
