Primaire uitkomstmaten
The phase shift of the sleep/wake cycle as evaluated by the time of DLMO directly after treatment.
Achtergrond van het onderzoek
About 80% of adults with Attention-Deficit/Hyperactivity Disorder (ADHD) have chronic sleep-onset problems and the majority of them has a Delayed Sleep Phase Syndrome (DSPS). DSPS is characterized by chronic sleep dept, which has negative consequences for physical health and is associated on the long term with weight gain, obesity, diabetes, hypertension, metabolic syndrome, cardiovascular disease, and even cancer. This study investigates the best treatment of DSPS (melatonin, placebo or melatonin and light therapy), and will determine whether patients with ADHD and DSPS have suboptimal biomarkers of chronic diseases like diabetes. Fifty-one adults with ADHD and DSPS will be recruited from the PsyQ Outpatient clinics in the Netherlands.
Doel van het onderzoek
This study will investigate the best treatment of Delayed Sleep Phase Syndrome (melatonin, placebo or melatonin and light therapy), and will determine whether patients with ADHD and DSPS have blood values that may indicate susceptibility for chronic diseases like diabetes.
The results will give insight into the association between DSPS, ADHD, and chronic conditions such as diabetes, and may serve as a model for the increase in obesity and metabolic syndrome in the general population, in which sleep loss is common due to the extended use of artificial light.
Onderzoeksopzet
All outcomes will be measured at baseline, directly after treatment and three weeks after treatment.
Methods of measurement:
Improvement of appetite hormones - blood
Improvement of diabetic parameters -blood
Improvement of biomarker profiles -blood
Improvement of cardiovascular parameters – ECG/ Ambulant Blood Pressure Monitor
Improvement of sleep parameters -actigraphy
Improvement of quality of life -questionnaire
Decrease of ADHD symptoms - questionnaire
Decrease of intake of carbohydrate-rich food -questionnaire
Treatment satisfaction -questionnaire
Onderzoeksproduct en/of interventie
Patients will be randomized for sleep education, plus:
(1) 0.5 mg of melatonin daily,
(2) 0.5 mg of placebo daily, or
(3) 0.5 mg of melatonin daily, plus 30 minutes of light therapy in the morning between 7 and 8 AM.
Each treatment takes three weeks; the Melatonin intake will be three hours before the patient’s individually determined Dim-Light Melatonin Onset (DLMO), and will be advanced during the treatment period.
