Introduction
Depression, anxiety and lack of impulse control are common neuropsychiatric symptoms in neurocognitive disorders and have been strongly associated with suicidality.
ObjectivesThe aim of this study was to explore suicide rates in three major neuropsychiatric conditions including various degenerative neurocognitive disorders (DND), alcohol related neurocognitive disorders (ARND), and traumatic brain injuries (TBI).
MethodsThe register cohort data of 231 817 patients with a diagnosis of degenerative dementias, ARND, or TBI, and their mortality data were collected from Finnish nationwide registers between 1998 and 2018. We calculated incidences of suicides, types of suicides, and suicide rates compared with the age- and sex matched general population (Standardized Mortality Ratio, SMR).
ResultsIn fifteen years since diagnosis, 0.3% (95% CI: 0.2 to 0.5) of patients with DND, 1.1% (0.7 to 1.8) of patients with ARND, and 1.0% (0.7 to 1.3) of patients with TBI died from suicide (Figure). Men died from suicide more often than women [58.9 (51.3 to 67.4) vs. 9.8 (7.5 to 12.5) per 100 000 person-years]. Of all three groups of patients, the highest number of suicides per 100 000 was in ARND (98.8; 65.1 to 143.8), then in TBI (82.0; 62.4 to 105.8), and then in DND (21.2; 18.3 to 24.5). The most common cause of death per 100 000 person-years was self-inflicted injury by hanging, strangulation or suffocation and drowning (12.4, 10.3 to 14.8), the second highest incidence self-inflicted poisoning (5.7, 4.3 to 7.4), and then self-inflicted injury by firearms, explosives, smoke, fire, flames, steam, hot vapours or hot objects (4.7, 3.4 to 6.2). The SMRs (95% CI) in the DND group were 1.31 (1.13 to 1.51) for the whole group, 1.21 (0.90-1.62) for women, and 1.34 (1.14-1.58) for men. The SMRs in the ARND group were 3.69 (2.53-5.38), 5.05 (1.90 to 13.46), and 3.52 (2.34 to 5.30), and in the TBI group 2.99 (2.31 to 3.86), 5.68 (3.22 to 10.00), and 2.66 (2.00 to 3.55), respectively.

ConclusionsSuicide rates were higher in all three patient groups compared with the same-aged general population. Risk for death from suicide remained elevated for more than ten years after the initial diagnosis. Men committed more suicides than women, but there was no difference between sexes in comparison with the age-matched general population. The suicide methods were mostly violent.

Background and aims:
Involvement with illicit drugs among young people has been explained by a risk-factor matrix. This study aims to compare childhood psychopathology as a predictor between self-reported illicit drug use without registered drug offending and police informed drug offending among males in a prospective birth cohort study.
Methods:A general population sample of 2946 8-year-old Finnish boys was followed up from age 8 to 18. In 1989, childhood psychopathology was assessed using the Rutter scale and Child Depression inventory. Information about self-reported drug use at age 18 or police-registered drug offending during years 16 to 20 years was collected from 79.3% (n=2336) of the subjects.
Results:Childhood psychopathology predicted exclusively police registered drug offending. After adjusting for family background, both severe and moderate conduct problems and ADHD symptoms were associated with subsequent police-registered drug offence. Self-reported illicit drug use was predicted only by non-intact family structure.
Conclusions:Our results demonstrate a clear difference, occurring already in childhood, between young men with self reported illicit drug use and those with police registered drug offending. More severe illicit drug involvement, such as police-registered drug offending, is a continuum of a childhood externalizing problem behaviour, while self-reported occasional illicit drug use does not inevitably associate with psychopathological problems in childhood. Accordingly, the preventive needs and the age period for intervention may be dissimilar for young people with divergent involvement with illicit drugs.
