Sleep paralysis and lucid dreaming are both dissociated experiences related to rapid eye movement (REM) sleep. Anecdotal evidence suggests that episodes of sleep paralysis and lucid dreaming are related but different experiences. In this study we test this claim systematically for the first time in an online survey with 1928 participants (age range: 18-82 years; 53% female). Confirming anecdota...

Previous stroboscopic studies of human vocal cord paralysis have been infrequent and have lacked documentation of the site of lesion. In order to study human laryngeal paralysis, the recurrent and superior laryngeal nerves were infiltrated unilaterally with lidocaine hydrochloride in three human volunteers. Vagal paralysis was simulated by combined (superior and recurrent) infiltration in one v...

Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB) facial paralysis of grade 6 was observed on the rig...

An 8-year-old boy with familial hypokalemic periodic paralysis is described. Twenty eight cases of periodic paralysis under 15 years of age were collected from the Japanese literature and reviewed. Serum potassium concentrations during an attack of paralysis were recorded in 27 cases including our case: 20 cases were hypokalemic, 4 were normokalemic and 3 were hyperkalemic. Hypokalemic periodic...

Abstract. This case of ascending paralysis, following an episode diarrhea, was initially misinterpreted as Guillain-Barré syndrome. The prominent hypokalemia led to the search for other differential diagnoses, interpreted a rare periodic hypokalemic which usually occurs in Asians after intake large amounts starch foods, such Spaghetti, or rest heavy exercise. In this case, reason with associate...

Altered communication (hoarseness, dysphonia, and breathy voice) that can result from vocal fold paralysis, secondary to numerous etiologies, may be amenable to surgical restoration. In this article, both traditional and cutting-edge phonosurgical procedures targeting the symptoms resulting from vocal fold paralysis are reviewed, with emphasis on the characteristic imaging appearances of variou...

Thyrotoxic periodic paralysis is a disease characterized by recurrent episodes of paralysis and hypokalemia during a thyrotoxic state. Thyrotoxic periodic paralysis is a common complication of hyperthyroidism in Asian populations, but can affect other ethnic groups as well. Due to population mobility, Thyrotoxic periodic paralysis is increasingly common in Western countries. Early diagnosis and...

Brain mechanisms of hypnosis are poorly known. Cognitive accounts proposed that executive attentional systems may cause selective inhibition or disconnection of some mental operations. To assess motor and inhibitory brain circuits during hypnotic paralysis, we designed a go-no-go task while volunteers underwent functional magnetic resonance imaging (fMRI) in three conditions: normal state, hypn...

Besides the hereditary hyperkalaemic paralysis, a secondary form exists which often mimicks Guillain-Barre syndrome. A 62 year old patient is reported on who developed severe hyperkalaemic paralysis on the basis of mild renal failure and additive spironolactone intake. Neurophysiological examinations disclosed normal muscle fibre activity but delayed nerve conduction velocities indicating that ...
