Variation in the CACNA1C gene has been associated with bipolar disorder in several genome-wide association studies. This gene encodes the alpha 1C subunit of L-type voltage-gated calcium channels, which play an essential role in neurons. We analysed 39 biomarkers in either cerebrospinal fluid or serum in relation to six different CACNA1C variants i...

Awareness materials featuring ways of coping with suicidal ideation can reduce suicidal ideation, the so-called Papageno effect. All of the previous experimental studies on this subject have been conducted with individuals not at risk of suicide. To assess effects of suicide awareness materials in a sample of individuals with recent suicidal ideati...

Recent research estimated that an additional 195 suicides among 10- to 17-year-old youths occurred following the release of the television series 13 Reasons Why. There is an underrecognised aspect in this line of research that this effect represents a net effect based on different possible underlying patterns (e.g. +195/-0 or +395/-200).

It has been hypothesised that refugees have an increased risk of suicide. To investigate whether risk of suicide is higher among refugees compared with non-refugee migrants from the same areas of origin and with the Swedish-born population, and to examine whether suicide rates among migrants converge to the Swedish-born population over time. A popu...
