The states of being are conventionally defined by the simultaneous occurrence of behavioral, neurophysiological and autonomic descriptors. State dissociation disorders are due to the intrusion of features typical of a different state into an ongoing state. Disorders related to these conditions are classified according to the ongoing main state and comprise: 1) Dissociation from prevailing wakefulness as seen in hypnagogic or hypnopompic hallucinations, automatic behaviors, sleep drunkenness, cataplexy and sleep paralysis 2) Dissociation from rapid eye movement (REM) sleep as seen in REM sleep behavior disorder and lucid dreaming and 3) Dissociation from NREM sleep as seen in the disorders of arousal...

Agrypnia (from the Greek: to chase sleep) excitata (AE) is a syndrome characterized by loss of sleep and permanent motor and autonomic hyperactivation (excitata). Disruption of the sleep-wake rhythm consists in the disappearance of spindle-delta activities, and the persistence of stage 1 non-rapid eye movement (NREM) sleep. Rapid eye movement (REM) sleep persists but fails to stabilize, appearing in short recurrent episodes, isolated, or mixed with stage 1 NREM sleep. Diurnal and nocturnal motor, autonomic and hormonal overactivity is the second hallmark of AE...

Agrypnia excitata (AE) is a syndrome characterized by the inability to sleep associated with a generalized motor and autonomic over-activation. AE is caused by a thalamo-limbic system dysfunction and comprises three different conditions: Fatal Familial Insomnia (FFI), Delirium Tremens (DT), and Morvan Syndrome (MS). Oneiric Stupor episodes (OS) are the peculiar motor behaviour of AE. During OS patients perform simple automatic gestures mimicking daily-life activities. This paper is the first description of the different characteristics of OS in two patients with MS and another with FFI, emphasizing the specific clinical features that reliably differentiate OS from REM sleep behaviour disorders...

The concept of Agrypnia excitata (AE) was originally proposed as a concept deriving from the clinical and anatomo-pathological observations obtained in three different diseases, Fatal familial insomnia (FFI), Delirium tremens (DT), and Morvan syndrome (MS). Agrypnia refers to a condition of severely reduced or absent sleep due to organic disorders. Excitata refers to the association of agrypnia with generalized motor and autonomic hyperactivation. AE is a syndrome that has been claimed to relate to a dysfunction in the thalamo-limbic circuits that govern sleep-wake cycles and autonomic activities...

INTRODUCTION: Morvan chorea is an antibody-mediated limbic encephalopathy characterized by severe insomnia, mental confusion, hallucinations, enacted dreams, hyperhidrosis, and neuromyotonia. CASE DESCRIPTION: In a 78 years old man presenting with progressive insomnia apathy and depression, a video-polysomnogram documented enacted dreams mimicking daily life activity (oneiric stupor). This finding led us to perform a search for serum antibodies to voltage-gated K+ channels, which was positive...

Agrypnia excitata is an extremely rare, life-threatening syndrome characterized by autonomic activation, persistent insomnia, and generalized overactivity. Agrypnia excitata describes a triad of three separate conditions: delirium tremens, Morvan's chorea, and familial fatal insomnia (FFI). Each of the aforementioned three conditions have sleep disturbances as a unifying theme and results in distinct neurophysiological findings. The following is an overview of agrypnia excitata with a particular emphasis placed upon each of the three individual conditions that constitute the syndrome with recommendations on appropriate management...

OBJECTIVE: Agrypnia Excitata (AE) is characterized by autonomic over-activity and cardiovascular fluctuations but direct evidence of sympathoexcitation is lacking. AE is a common feature of acquired (i.e. Morvan's syndrome--MS) and genetic (i.e. fatal familial insomnia--FFI) conditions where a dysfunction of the thalamo-limbic system has been suggested. The aim of this study is to report the first microneurographic recordings of sympathetic activity in acquired and genetic AE to investigate the pattern of sympathetic activation...

Mulvihill-Smith syndrome (MSS) is characterized by premature aging, multiple pigmented nevi, decreased facial subcutaneous fat, microcephaly, short stature, mental retardation and recurrent infections, however the adult phenotype of MSS has yet to be delineated. We report a 28-year-old woman with Mulvihill-Smith syndrome, who had a solid pseudopapillary cystic tumor of her pancreas at age 17 years. Her distinctive sleep pattern includes severe insomnia with disappearance of sleep spindles and K-complexes, persisting muscle tone, and loss of slow wave sleep...

Fatal familial insomnia, a human prion disease, Morvan's chorea, an autoimmune limbic encephalopathy, and delirium tremens, the well-known alcohol (or benzodiazepine [BDZ]) withdrawal syndrome, share a clinical phenotype largely consisting in an inability to sleep associated with motor and autonomic activation. Agrypnia excitata is the term which aptly defines this clinical condition, whose pathogenetic mechanism consists in an intralimbic disconnection releasing the hypothalamus and brainstem reticular formation from corticolimbic inhibitory control...

This review summarizes the pioneering steps culminating in the identification of a novel disease, fatal familial insomnia (FFI), a hereditary prion disease. Together with Morvan's chorea and delirium tremens, FFI is characterized by an inability to sleep associated with motor and autonomic overactivation. We named this pattern agrypnia excitata, a syndrome caused by a dysfunction in thalamolimbic circuits. This review highlights the strategic role of the limbic thalamus in the central autonomic network running from the limbic cortex to the lower brainstem and regulating sleep and wakefulness...

We report the video-polysomnographic sleep characteristics of a 25-year-old woman with the Mulvihill-Smith syndrome, a rare clinical condition characterized by progeria-like aspect, peculiar multiple pigmented nevi, low stature, and cognitive impairment. Among the various exams, two overnight video-polysomnographic recordings were carried out; moreover, cerebral MRI and molecular analysis of the prion protein gene (PRNP) were also performed. The video-polysomnographic recordings showed the absence of clear sleep episodes but the presence of periods during which the patient had poor contact with the environment, stereotyped afinalistic movements of the upper limbs and hands, irregular or periodic breathing (with central apnea episodes), heart rate arrhythmia, and rapid eye movements...

Fatal Familial Insomnia (FFI) is characterized by loss of sleep, oneiric stupor with autonomic/motor hyperactivity and somato-motor abnormalities (pyramidal signs, myoclonus, dysarthria/dysphagia, ataxia). Positon emission tomography (PET) disclosed thalamic hypometabolism and milder involvement of the cortex; neuropathology severe neuronal loss in the thalamic nuclei variably affecting the caudate, gyrus cinguli and fronto-temporal cortices. Genetic analysis disclosed a mutation in the PRNP gene and FFI was transmitted to experimental animals, thus classifying FFI within the prion diseases...

Insomnia is the most common sleep complaint. Insomnia is not a disease itself but mostly a clinical sign of an underlying disease. Degenerative and vascular diseases involving the central nervous system (CNS) may impair sleep either as a result of the brain lesion or because of illness-related discomfort (motor immobility, social and familial impairment, depression, drugs). Some neurological conditions characterized by movement disorders that start or persist during sleep hinder sleep onset and/or sleep continuity, causing a poor sleep complaint...

The spectrum of rapid eye movement behavior disorders (RBD) spans various age groups, with the greatest prevalence in elderly men. Major diagnostic features include harmful or potentially harmful sleep behaviors that disrupt sleep continuity and dream enactment during rapid eye movement sleep. In RBD patients, the polysomnogram during rapid eye movement sleep demonstrates excessive augmentation of chin electromyogram or excessive chin or limb phasic electromyogram twitching. RBD may be associated with various neurodegenerative disorders, such as multiple system atrophy, Parkinson's disease, and dementia with Lewy bodies...

Fatal familial insomnia, Morvan's chorea and delirium tremens share the same clinical features: severe insomnia and mental confusion with dream enactment, associated with motor and autonomic activation. Polygraphically, they share an inability to generate slow wave sleep. Agrypnia excitata is the term which aptly defines this peculiar medical condition. In fatal familial insomnia, the syndrome is due to a functional imbalance between activating and deactivating structures within the limbic system provoked by the atrophy of the mediodorsal and anteroventral thalamic nuclei...
