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.

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...
