Sexual risk-taking has consequences for young women with ADHD and in this study we investigate knowledge and challenges in reproductive health and contraceptive counselling at Swedish youth clinics. Midwives need better evidence-based tools to meet the…

We show that both mothers and fathers of survivors of adolescent cancer are at increased risk of use of anxiolytics and sedatives immediately following their child’s cancer diagnosis. But only mothers have a higher risk of antidepressant use from 6 months…

In this case report we discuss how both opioid agonist and opioid antagonist treatment may improve social functioning, depending on an individual's opioid tone before treatment. Given the extensive unmet medical needs in individuals with autism spectrum…

Sexual risk-taking has consequences for young women with ADHD and in this study we investigate knowledge and challenges in reproductive health and contraceptive counselling at Swedish youth clinics. Midwives need better evidence-based tools to meet the…

Just over 2 percent of older adults (>50 years) live with ADHD, low self-esteem, quality of life, and social connectedness, as well as a high degree of psychiatric and somatic health problems. Few studies have investigated drug treatment and…

In this review article, we describe how ADHD is influenced by a combination of genetic and environmental factors. Undiagnosed and untreated ADHD can lead to serious consequences for the individual and significant costs for society. ADHD can be treated…

In this review article, we describe the current state of knowledge regarding the comorbidity of ADHD, addiction, and criminality. Evidence-based treatment should be offered concurrently, preferably within the same healthcare unit, and the requirement for…

I had the great honor of being the editor for a special issue on ADHD in the Medical Journal. This is my introductory piece.

At surgical abortion, sociodemographic and psychiatric risk factors for recurrent unwanted pregnancy increased the provision of long-acting reversible contraceptives (LARC). However, we show that improved access and tailored counseling could lead to an…

In this study we explored motives for using or abstaining from substances among students in affluent areas as well as their attitudes to, and suggestions for, substance use prevention. Our results show the importance of parental involvement,…

In this nationwide register study, we show that children with anorectal malformations have a higher risk of ADHD and autism spectrum disorders than controls.

In this multicenter European study, we examined parental experiences of homeschooling during the COVID-19 pandemic in families with or without a child with a mental health condition and concluded that adverse effects of homeschooling may have a long-term…

We show that women with ADHD, compared to controls, had an increased risk of preterm and very (<32 weeks) preterm births, for both spontaneous and medically indicated onsets.

In this study we show that women with a greater burden of pre-pregnancy psychiatric illness are more likely to re-initiate their antidepressant treatment during pregnancy. Clinicians may consider both risks and benefits of discontinuing antidepressants…

Cancer during adolescence is associated with increased risk of mental health problems that may develop in close proximity to treatment. Our findings emphasize the need for comprehensive care during treatment and follow-up of survivors.

Cost-effective and easily disseminated interventions targeting adolescent substance use are warranted, and we test the effectiveness of a fully automated digital brief intervention aimed at reducing alcohol and substance use in adolescents and young…

Previous studies show that ADHD medication reduce the risk of unintentional injuries and we show that these beneficial effects also include individuals with co-occurring neurodevelopmental disorders.

While Swedish youth clinics successfully have targeted risk of unplanned pregnancies in adolescents, young ADHD might not be reached by these interventions. We found that they had a 6 times higher risk of becoming teenage mothers compared with unaffected…

We established, in a previous study, that ADHD and Borderline (BPD) share genetic factors, but how much of the overlap is explained by genes and how much can be attributed to other factors.

In this study we show that many of the adolescent and young adult visitors at Swedish youth clinics use alcohol and drugs in a risky way often associated to sexual risk-taking and suggest that youth clinics are an important arena for alcohol prevention.

Children with Hirschsprung disease are usually subjected to many treatments during infancy and may struggle with consequences from this even after surgery. We show that they also are at higher risk for depression compared to controls.

Even though previous studies have shown an association between Hirschsprung disease and maternal SSRI use during pregnancy, our population-based Swedish cohort study could not find any increased risk.

ADHD is a prevalent deficit that more often than not remains into adulthood. A lot of elders gain knowledge - and understanding - of lifelong neuropsychiatric vulnerability when their children or grandchildren are diagnosed.

Children with Hirschsprung disease need more special education services despite normal intelligence, but do they also have ADHD more often than others? Not according to our register-based study of 739 Hirschsprung cases and 7390 controls.

Why is borderline personality disorder (BPD or EIPS) more common in ADHD? We show that it could be due to shared genetic factors.

How is risky sexual behavior and alcohol- and drug use associated? We discuss potential barriers to develop and implement prevention policies at Swedish youth health clinics.

Clinicians often lack guidance in treating individuals with ADHD and comorbid addiction. We show that patients with ADHD and addiction were prescribed 40% higher stimulant doses without signs of tolerance.

Why is alcohol, despite the risks for interpersonal violence, viewed as a focal element of large football events? We show that there is a strong public consensus for strategies to reduce alcohol sales and intoxication levels at public football games.

Adherence to treatment is associated with a favorable treatment outcome. In this study, we show that higher stimulant doses were associated with long-term treatment adherence in individuals with ADHD and addiction.

My doctoral thesis, Karolinska Institutet 2015, suggest that ADHD and SUD share common genetic factors, that individuals with ADHD and substance use disorders use higher stimulant doses than those with ADHD only, without showing signs of tolerance, and…

What could explain the large overlap between ADHD and substance use disorders? In this large national cohort study, we suggest that it’s probably due to shared genetic factors.

Can exhaled breath be used for drug testing instead of urine or blood? Rather. We show that it was the preferred way for the participants as well as a sufficient, non-invasive and safe alternative to other sampling.

Previous research show that women who smoke during pregnancy have a higher risk of getting a child with ADHD, suggesting a causal negative effect of nicotine. But we show that this association also can be explained by heritability of ADHD.
