Cerebrotendinous xanthomatosis (CTX) is a rare genetic disorder characterized by a variety of neurological and systemic symptoms, including cerebellar ataxia, cataracts, tendon xanthomas, and polyneuropathy. This study aimed to investigate sleep patterns and disorders in four patients diagnosed with cerebrotendinous xanthomatosis. All participants reported significant sleep disturbances, and objective assessments confirmed the presence of insomnia, excessive daytime sleepiness, obstructive sleep apnea, and periodic limb movements. Notably, this is the first study to incorporate sleep assessments into the clinical management of CTX patients, which may be crucial for improving their quality of life. Further research is warranted to deepen our understanding of the potential impact of cholestanol deposits on regions of the central nervous system involved in sleep and circadian rhythm regulation.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
