What role did altered states of consciousness play in the life of ancient Greek society?  With consummate skill and scholarship, Yulia Ustinova answers this question in her book, Divine Mania: Alteration of Consciousness in Ancient Greece. It appears that the secret of the extraordinary creativity of the ancient Greeks was their receptivity to, and approval of, a particular altered state of consciousness they cultivated.  Mania is the name for this but it must be qualified as “god-given.” Mania is a word that touches on a cluster of concepts: madness, ecstasy, and enthusiasm, engoddedness, to use Ustinova’s more vivid coinage. It seems a paradox that this special, strange and often quite frightening state of dissociation should be so closely linked to one of the most creative civilizations.  Unlike the Roman and Egyptian, the Greek approved and recognized the value of god-inspired mania. Plato makes Socrates say in the Phaedrus that through mania we may obtain the “greatest blessings.” Whereas resistance to divine ecstasy can end in disaster, as Euripides illustrates in The Bacchants when Pentheus, a repressive authoritarian, tries to inhibit a posse of women from their ecstatic mountain dances. He is torn to shreds by his mother and her maniacal cohorts.   This mindset of the ancient Greeks may have long ago petered out, but similar tendencies are constants, expressed in one form or another, throughout history.

Abstract Background For a century, psychedelics have been investigated as models of psychosis for demonstrating phenomenological similarities with psychotic experiences and as therapeutic models for treating depression, anxiety, and substance use disorders. This study sought to explore this paradoxical relationship connecting key parameters of the psychotic experience, psychotherapy, and psychedelic experience. Methods In a randomized, double-blind, placebo-controlled, crossover design, 24 healthy volunteers received 50 μg d-lysergic acid diethylamide (LSD) or inactive placebo. Psychotic experience was assessed by aberrant salience (Aberrant Salience Inventory, ASI), therapeutic potential by suggestibility (Creative Imagination Scale, CIS) and mindfulness (Five Facet Mindfulness Questionnaire, FFMQ; Mindful Attention Awareness Scale, MAAS; Experiences Questionnaire, EQ), and psychedelic experience by four questionnaires (Altered State of Consciousness Questionnaire, ASC; Mystical Experiences Questionnaire, MEQ; Challenging Experiences Questionnaire, CEQ; Ego-Dissolution Inventory, EDI). Relationships between LSD-induced effects were examined. Results LSD induced psychedelic experiences, including alteration of consciousness, mystical experiences, ego-dissolution, and mildly challenging experiences, increased aberrant salience and suggestibility, but not mindfulness. LSD-induced aberrant salience correlated highly with complex imagery, mystical experiences, and ego-dissolution. LSD-induced suggestibility correlated with no other effects. Individual mindfulness changes correlated with aspects of aberrant salience and psychedelic experience. Conclusions The LSD state resembles a psychotic experience and offers a tool for healing. The link between psychosis model and therapeutic model seems to lie in mystical experiences. The results point to the importance of meaning attribution for the LSD psychosis model and indicate that psychedelic-assisted therapy might benefit from therapeutic suggestions fostering mystical experiences.

Abstract Background Perampanel (PER) is a novel antiepileptic drug (AED) which employs a completely different mechanism of action compared to existing medications. Overall, PER is considered to be safe up to a dose of 12 mg per day. When used to treat refractory and super-refractory status epilepticus, PER seems to be extremely well tolerated; this is true even when used at doses of up to 32 mg. There are currently only three case reports on the effects of acute PER overdose in epilepsy patients. Case presentation We report a 16-year-old Thai woman with a low body weight, who took PER at a dose of 40 times that of the prescribed daily dose. She experienced only an alteration of consciousness, without any systemic medical effects, and made a full recovery within 3 days without gastric lavage or specific treatment. Conclusion Our report demonstrates that an acute PER overdose may not produce serious adverse systemic effects. Individuals with adverse central nervous system (CNS) effects, such as altered consciousness, can experience a rapid recovery.

Abstract Objectives Serious hyperinsulinemic hypoglycemia (HH) is generally the main initial symptom of hyperinsulinism. Epilepsy, without any overt feature of hypoglycemia, might be a very rare initial presentation of late-onset isolated hyperinsulinism. Case presentation We describe a case of late-onset HH in a 15-year-old boy with a history of idiopathic generalized epilepsy, now named genetic generalized epilepsy (IGE/GGE), beginning with a tonic–clonic seizure at the age of 11 years. Subsequently, absences with rare eyelid myoclonia were recorded on electroencephalogram (EEG), followed by episodes of impaired consciousness with facial myoclonia. Neurological status was normal except attention-deficit hyperactivity disorder (ADHD). At the age of 15 years, an episode of slight alteration of consciousness with neurovegetative signs could be recorded, which did not correspond to an absence status. Hypoglycemia due to hyperinsulinism was documented (clinically, biologically, and genetically). Diazoxide treatment resolved the glycopenic symptoms, the non-hypoglycemic seizures and normalized brain electrical activity allowing complete withdrawal of antiepileptic medication. Conclusions Epilepsy can be a very rare initial feature of HH starting in childhood. The occurrence of atypical features in the context of GGE as “absence statuses” with unusual vegetative symptoms and facial myoclonia might be suggestive for HH. Careful assessment and specific treatment are necessary to prevent hyperinsulinism related brain damage. Our case showed that diazoxide might also resolve seizures and normalize EEG.

Introduction. Although the posterior reversible encephalopathy syndrome (PRES) is often associated with headache and visual changes, central-variant PRES can be difficult to clinically diagnose in a patient with alteration of consciousness. Central-variant PRES has been previously described in the literature affecting subcortical white matter and the brainstem. Case Presentation. We describe a case presenting with hypertension (192/98) and altered level of consciousness requiring intubation. She was ultimately found to have extensive symmetric cortical and subcortical edema, with extensive involvement of bilateral thalami, consistent with central-variant PRES. Her mentation rapidly improved with blood pressure management. Confirmation of the diagnosis of central-variant PRES was made on repeat brain imaging. Our case is unique in demonstrating dramatic central white matter changes and their reversibility on repeat imaging six days later. Finally, persistent cognitive deficits at follow-up four months later are described. Conclusion. Atypical presentations of PRES, involving alterations in levels of consciousness, can be difficult to clinically diagnose. A thorough differential diagnosis is even more important in cases of PRES with atypical imaging. Recognition of the diagnostic patterns of PRES on brain imaging, with prompt reversal of the causative factors, is crucial for the appropriate care of these patients. The long-term sequelae, which could include cognitive deficits, are poorly studied and understood.

Abstract As a commonly used anesthetic agent, midazolam has the properties of water-soluble, rapid onset, and short duration of action. With the rapid development in the field of neuroimaging, numerous studies have investigated how midazolam acts on the human brain to induce the alteration of consciousness. However, the neural bases of midazolam-induced sedation or anesthesia remain beginning to be understood in detail. In this review, we summarize findings from neuroimaging studies that have used midazolam to study altered consciousness at different levels and content. We also compare the results to those of neuroimaging studies using diverse anesthetic agents and describe the common neural correlates of anesthetic-induced alteration of consciousness.

Abstract Casestudy: Testicular tumors account for 1–2% of all tumors in men, with 95% of these being germ cell tumors. The main risk factor for the development of testicular cancer is cryptorchidism. Paraneoplastic limbic encephalitis is a rare sequela of testicular tumor associated with anti-Ma2 and KLH11 antibodies. The most effective treatment for paraneoplastic limbic encephalitis is treatment of the primary malignancy. We present a 41-year-old male that presented to the emergency department with two weeks of episodic alteration of consciousness and memory disturbances. Negative neurologic evaluation and imaging led to concern for a paraneoplastic process from a distant malignancy. CT imaging revealed an enlarged, necrotic para-aortic lymph node and subsequent ultrasound demonstrated a right sided testicular mass. Right radical orchiectomy was performed. Microscopically, the mass consisted of mixed respiratory epithelium, gastrointestinal glands and squamous epithelium with keratinization consistent with a post-pubertal testicular teratoma with associated in-situ germ cell neoplasia. Resection of the para-aortic mass revealed large anaplastic cells with epithelioid features, nuclear pleomorphism and frequent mitoses. Immunostaining was positive for Pan-Keratin and OCT4, consistent with poorly differentiated embryonal carcinoma. Resection of the primary and metastatic disease, as well as treatment with corticosteroids resulted in resolution of the encephalitis. This presentation of severe neurological disturbances in the setting of a metastatic mixed nonseminomatous germ cell tumor represents a rare presentation of paraneoplastic limbic encephalitis.

Background: Stroke is a leading cause of mortality and disability worldwide. To prevent complications and permanent defects, early diagnosis, distinguishing the type and risk factor of stroke is crucial. Methodology: It was a hospital based cross sectional study, purposive sampling method was used, and a total of 469 stroke patients admitted into Department of Medicine, Rangpur medical college hospital, Bangladesh were included in this study. Results: In this study we have studied of 469 acute stroke patients. Among them 81% (380) were ischemic stroke patients and 19% (89) were hemorrhagic stroke. Overall male were more than female 308 (65.7%) vs 161(34.4%). The mean age for the ischemic stroke group was 64.1 ± 10.9 years, which was significantly higher than that of the hemorrhagic group (59.8 ± 9.60years) (P<0.05). Acute hemorrhagic stroke patients presented with acute onset of focal neurological deficit 61.8%, headache 64%, vomiting 59.6%, alteration of consciousness 48.3% and convulsion 27%. On the other hand, acute ischemic stroke patient presented with alteration of consciousness 65.5%, acute onset of focal neurological deficit 39.5%, paralysis 41%, deficit after awakening 32.4% and aphasia 34.7%. Among the risk factors of stroke in acute ischemic stroke patients hypertension was 59.2%, diabetes mellitus 20%, history of previous stroke 16.1%, ischemic heart disease 14.5% and atrial fibrillation 10.3% were present, on the other hand in acute hemorrhagic stroke patients hypertension 76.4%, smoking 70.8% and diabetes mellitus 6.7% were present. 26.97% of the acute hemorrhagic stroke and 13.9% of the acute ischemic stroke patients died in hospital. Conclusion: Common presentation of stroke was acute onset of focal neurological deficit; headache and vomiting were more in hemorrhagic stroke patient; alteration of consciousness, paralysis was predominant in ischemic stroke patient.

Ancient Greece was unique in its attitude to alteration of consciousness. Various altered states of consciousness were commonly known: initiates experienced them during mystery rites; sacred officials and enquirers attained them in the major oracular centres; possession by various deities was recognized; and some sages and philosophers practised manipulation of consciousness. From the perspective of individual and public freedom, the prominent position of mania in Greek society reflects its openness and acceptance of the inborn human proclivity to experience alterations of consciousness, which were interpreted in positive terms as god-sent. These mental states were treated with cautious respect, but never suppressed or pushed to the cultural and social periphery, in contrast to many other complex societies, ancient and modern.
