Wilson disease (WD) is a rare genetic disorder characterized by copper overload in the liver and the brain. Neurological presentations are mainly related to the accumulation of copper in the basal ganglia, the brainstem, and the cerebellum. Dysarthria is a frequent symptom, with dystonic, spastic, or parkinsonian components and is usually resistant to medical or voice rehabilitation therapies. ...

Eszopiclone (Lunesta; Sepracor, Marlborough, MA) and zolpidem [N,N,6-trimethyl-2-(4-methylphenyl)-imidazo(1,2-a)pyridine-3-acetamide] are among the most commonly prescribed hypnotics in use in the United States. The thalamus plays a pivotal role in sleep regulation and rhythmicity. Two distinct subtypes of synaptic GABA(A) receptors (GABA(A)-Rs), alpha(1)beta(2)gamma(2) and alpha(3)beta(3)gamma...

In mammals, identifying the contribution of specific neurons or networks to behavior is a key challenge. Here we describe an approach that facilitates this process by enabling the rapid modulation of synaptic inhibition in defined cell populations. Binding of zolpidem, a systemically active allosteric modulator that enhances the function of the GABAA receptor, requires a phenylalanine residue (...

Zolpidem is the most commonly prescribed medication for the short-term treatment of insomnia. Adverse reactions include nightmares, confusion, and memory deficits. Reported rare adverse neuropsychiatric reactions include sensory distortions such as hallucinations. Previous research has identified 4 factors that may place a patient at increased risk of zolpidem-associated psychotic or delirious ...

BACKGROUND We conducted a study using a case-crossover design to clarify the risk of acute effects of zolpidem and benzodiazepine on all-sites of fractures in the elderly. DESIGN OF STUDY Case-crossover design. METHODS AND MATERIALS Elderly enrollees (n = 6010) in Taiwan's National Health Insurance Research Database with zolpidem or benzodiazepine use were analyzed for the risk of developin...

Progressive supranuclear palsy (PSP) is a debilitating progressive neurodegenerative disorder for which there is no proven pharmacological treatment. Zolpidem immediate release formulation has been reported to show short-term improvements in motor function and voluntary saccadic eye movements, but the benefits were not sustained. A 61-year-old man with a 4-year history of PSP was observed over ...

Hypnotic drugs designed to treat insomnia in adults are now increasingly used in children, but the effects of these compounds on neonatal sleep are poorly understood. We investigated the hypnotic effects of the commonly prescribed non-benzodiazepine sleep agent Zolpidem (Ambien) on sleep architecture and electroencephalographic (EEG) activity in the neonatal ferret. Six ferret kits were surgica...

Benzodiazepines (BDZs) are known to increase the amplitude and duration of IPSCs. Moreover, at low [GABA], BDZs strongly enhance GABAergic currents suggesting the up-regulation of agonist binding while their action on gating remains a matter of debate. In the present study we have examined the impact of flurazepam and zolpidem on mIPSCs by investigating their effects on GABA(A)R binding and gat...

Zolpidem, a non-benzodiazepine hypnotic, was identified in the blood of 29 subjects arrested for impaired driving. Zolpidem concentrations ranged from 0.05 to 1.4 mg/L (mean 0.29 mg/L, median 0.19 mg/L). In the subjects whose cases we reviewed where zolpidem was present with other drugs and/or alcohol, symptoms reported were generally those of CNS depression. Symptoms included slow movements an...

To examine the efficacy of the melatonin receptor agonist ramelteon for nocturia, it was compared with zolpidem, a conventional non-benzodiazepine hypnotic. A total of 50 patients with nocturia (2 urinations/night) were enrolled. Subjects assigned odd numbers or even numbers were respectively prescribed 8 mg of ramelteon (n = 27; mean age: 75 years) or 5 mg of zolpidem (n = 23; mean age: 73 ye...
