Although sleep disorders are increasingly recognized in TSC, they remain poorly described in adults. Additionally, the influence of clinical features and commonly used medications on sleep is not well understood. This study assessed sleep disorders in adults with TSC and examined contributing clinical and treatment factors. Adults were recruited through the TSC Alliance and the TSC Center of Excellence (CoE) at UTHealth Houston. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, and demographic, clinical, lifestyle, and medication information was collected from 84 adults. Descriptive and inferential statistics were applied, with significance set at <i>p</i> < 0.05. Overall, 64% (<i>n</i> = 54) met criteria for poor sleep, significantly higher than rates reported in neurotypical adults (<i>p</i> < 0.001). Participants with mental illness or anxiety more frequently reported sleep issues (<i>p</i> = 0.009, <i>p</i> = 0.04). Poor sleep was also associated with use of mTOR inhibitors, antiepileptic drugs, and antidepressants (<i>p</i>\u0000 <sub>AD</sub> = 0.016, <i>p</i>\u0000 <sub>mTORi</sub> < 0.001, <i>p</i>\u0000 <sub>AEDs</sub> = 0.045).
