Introduction: ADHD is a neurodevelopmental disorder characterized by hyperactivity, inattention and impulsivity. For many the core symptoms become less troubling in adulthood. Treatment with stimulants is considered the most efficacious treatment for ADHD. Large high-quality studies have estimated the prevalence of AHDH to be 3,4-7,2% for children and adolescents and 2,5-6,8% for young adults. The aim of this study was to estimate the proportion of Icelanders who have received an ADHD diagnosis based on ADHD-medication prescriptions since an ADHD diagnosis is a prerequisite for such prescriptions in Iceland., Methods: This population-based retrospective cohort study included all Icelanders 7-70 years old who received a prescription for an ADHD drug from 1.1.2004-31.12.2023. Every citizen receiving a prescription is included in the Icelandic Prescription Medicines Registry (IPMR)., Results: In 2023 14,7% of youth, 7-17 years of age, received a prescription for an ADHD medication, 17,7% of boys and 11,6% of girls. Among 12-17 years old youth the proportion was higher still, 17,6%, 20,1% for boys and 14,6% for girls. For 18-44 years old adults the proportion was 10,2%, 9,4% for males and 11,0% for females. From 2010-2023 the increase in prescriptions for 7-17 years old boys has been 93% but 224% for girls. For 18-44 years old males the increase has been 414% for males and 543% for females during this period. The incidence of new ADHD prescriptions for 7-17 years old boys from 2021-2023 was 10,9 and 13,5 for girls per 1000, respectively. For 18-44 years old the incidence in the years 2021-2023 was 18,7 for males and 19,2 for females per 1000, respectively., Conclusion: The prevalence of Icelanders who have received an ADHD diagnosis is double to treble that observed in the best available studies in other populations. We therefore call for an urgent review of how ADHD diagnoses are made in Iceland because it is obvious that the current system leads to overdiagnosis and inappropriate treatment.

In view of the ongoing rise of ADHD prescriptions among adults in Iceland, it is important that doctors are aware that psychosis is a rare but at times a serious adverse reaction to such treatment. In 2022 5% of adults were prescribed medication to treat ADHD in Iceland. In this case report we present a case of methylphenidate-induced psychosis in a young man with no previous history of psychotic episodes who required admission to the psychiatric intensive care unit.

Background: Because of the early onset and disabling symptoms of schizophrenia spectrum disorders many individuals with these disorders are unemployed from an early age and disability pension rates are high. The aim of this study was to assess functional recovery and identify vocational predictors among young first episode psychosis patients registered in an early intervention psychosis center in Iceland in 2010-2020., Methods: The study is a retrospective cohort study based on the medical records of those who were discharged from Laugaras, the only early intervention psychosis program in Iceland after six months or longer rehabilitation in 2010-2020 (n=144). Univariate and multivariate logistic regression was used to identify vocational predictors., Results: 75% of patients were unemployed at admission to the early intervention center but over half of the patients were employed or in school at discharge. Vocational rehabilitation was the strongest vocational predictor (OR 13.93, 95% CI 3.85-63.89). Other vocational predictors were those that reflect a disabling psychiatric disorder and social functioning before the onset of early intervention. 66% of patients had a history of cannabis use which had a negative impact on employment and education at discharge., Conclusions: In spite of intensive rehabilitation at an early intervention center, almost half of the patients were neither employed nor in school at discharge. The strongest vocational predictor was vocational rehabilitation which was also one of few vocational predictors that can be influenced by admission to an early intervention psychosis center. It therefore seems important to ensure that effective vocational rehabilitation is readily available at early intervention psychosis centers.

Objective: PNHA is a standardized evaluation of the elderly which everyone who applies for an admission to long term care (LTC) in Iceland must undergo. The objective of this study is to describe the elderly who asked for an admission to LTC in The Reykjavík metropolitan area and in Akureyri over a 10 year period. A special attention is paid to factors that could possibly predict survival after PNHA., Material and Methods: Every PNHA evaluation is stored in a database by SKYRR Inc. Information from that database regarding all who lived in the greater Reykjavík area and Akureyri and had undergone their first PNHA during the period from January 1st 1992 to 31st of December 2001, was collected. Information about survival was collected from the the Icelandic national registry. There were 4272 individuals in the study group. SPSS was used for statistical analysis., Results: The average enrolment age of men in nursing homes(NH) in Reykjavík was 82.7 -/+ 0.5 years and for women 84.4 -/+ 0.4 (p<0.01). Men were about one third of residents in NH's. The average waiting time for men from the first PNHA to NH placement was 219 -/+ 20 days and for women 290 -/+ 22 days (p<0.01). Of those who were waiting for NH's, 22% of men and 14% of women died without being admitted (p<0,01). The mean survival of men in NH's in Reykjavík was 2.5 -/+ 0.2 years and for women 3.1 -/+ 0.2 years (p<0.01). Factors predicting longer survival for men in Reykjavík were lower age, good mobility and being able to eat but for women the factors were lower age and good mobility., Conclusions: It's in all stakeholders' interest that elderly people are enabled to live at home for as long as possible. Factors that predict survival should be taken into account when the elderly are prioritized for admission to NH's so that elderly who are predicted to have the lowest survival rate of assessed are those admitted first.
