A case of fatal familial insomnia: diagnostic and therapeutic approaches
1Department of Neurology, Duke University School of Medicine, Durham, NC, USA.
Abstract:
Fatal Familial Insomnia (FFI) is an uncommon but fatal genetic condition that is characterized by severe progressive insomnia, dysautonomia, neuropsychiatric changes, and gait instability. Diagnostic workup includes genetic testing, EEG, MRI imaging of the brain, polysomnography, and CSF analysis. MRI brain imaging may be notable for areas of restricted diffusion in the thalamus. Therapeutic approaches are centered on symptom management, predominantly for insomnia. It is important for clinicians to consider FFI in patients presenting with progressive insomnia, cognitive deficits, and gait instability, and to direct patients and families toward genetic counseling and palliative care services.

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...

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
