Abstract:
In the last years, actigraphy has been used more often for clinical research and research evaluation of sleep disorders. Compared to polysomnography, actigraphy is cheap and less time-consuming. Actigraphy provides more objective information about sleep than sleep logs. Although the algorithms to score sleep and wake based on motions measured by actigraphy are still being improved, we believe that the role of actigraphy in the clinical evaluation of sleep in insomnia is limited. Instead of using actigraphy to distinguish a wakeful state from sleep in insomnia, we might better use the activity plots which the actigraph provides to get more insight into the physiological hyperarousal or restfulness of insomnia patients.

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...
