Hyperactivity in patients with narcolepsy and idiopathic hypersomnia: an exploratory study

Abstract Introduction Patients with either Idiopathic Hypersomnia or Narcolepsy demonstrate excessive daytime somnolence (EDS) resultant inattention mimicking Attention Deficit Hyperactivity Disorder (ADHD). ADHD also often express sleep problems including EDS. Thus, patients and idiopathic hypersomnia narcolepsy may share drowsiness as common features. However, it is not known whether EDS have increased movement (hyperactivity) like patients, the determination of which purpose this study. Methods We studied 12 (7 type 2 5 Hypersomnia) shown by Multiple Sleep Latency Test served gold standard for entry into Twelve subjects without symptoms control group. None participants had a previous history ADHD. Each participant underwent one-hour session laying at 45 degrees surveys about need to move actigraphy an objective measure movement. Results Sleep-disordered reported more hyperactivity on Self-Report Scale. At each time points clear trend than controls Suggested Immobilization (SIT). For total 60 min, large effect size during SIT test was found between (Cohen’s d = 0.61, p 0.01). did combat controls, nor show any difference in SIT. Conclusion controls. verified measurement, hypothesis be further tested, model inattentive form rather combined inattentive/hyperactive Further studies are needed explore relationship hyperactivity.
