Søvn hos voksne med ADHD

I denne studien ble det undersøkt prevalens av insomi hos voksne pasienter med ADHD. Totalt ble 268 voksne med ADHD og 202 tilfeldig utvalgte kontroller inkludert i studien. Forekomst av insomni var signifikant høyere blant voksne med ADHD sammenlignet med kontrollgruppen. Insomni var mer vanlig hos de med ADHD kombinert type enn hos de med ADHD uoppmerksom type. Forekomst av insomni var ikke høyere blant de pasientene som fikk adekvat medikamentell behandling sammenlignet med de som ikke fikk medikamentell behandling. Studien er utført av forskere fra Universitetet i Bergen og Haukeland universitetssykehus.

Objective: To investigate the prevalence of insomnia in adults with Attention-deficit hyperactivity disorder (ADHD) and its association with clinical subtypes, current ADHD symptoms, and stimulant treatment.

Method: We obtained diagnostic information, symptom rating scales and treatment history from clinically ascertained adult ADHD patients diagnosed according to DSM-IV criteria (n = 268, mean age 38.1 years) and randomly selected population controls (n = 202, mean age 36.5 years). The Bergen Insomnia Scale (BIS) was used to measure insomnia. ADHD symptom domains were self-rated using the Adult ADHD Self-Rating Scale.

Results: Insomnia was far more frequent among adults with ADHD (66.8%) than in the population controls (28.8%) (P < 0.001). Insomnia was more common in adults with the combined subtype than in those with the inattentive subtype (79.7% and 55.6%, respectively) (P = 0.003). For self-reported current ADHD symptoms, inattention was strongly correlated to insomnia. Patients currently using stimulant treatment for ADHD reported a lower total insomnia score compared to patients without medication (P < 0.05).

Conclusion: Insomnia was highly prevalent among adults with ADHD. The lower insomnia score in patients on current stimulant treatment suggests that stimulant treatment is not associated with worsening of insomnia symptoms in adult ADHD patients.
