We investigated the clinical predictors of the degree of recovery in patients with prolonged disorders of consciousness (PDC) caused by traumatic brain injury. Fourteen patients with PDC underwent two diffusion tensor imaging (DTI) studies; the first and second scans were performed at 345.6 ± 192.6 and 689.1 ± 272.2 days after the injury, respectively. In addition to the temporal changes in each of these diffusion parameters, fractional anisotropy (FA), mean diffusivity, axial diffusivity (AD), and radial diffusivity were assessed over a 1-year period...

Brain injuries substantially change the entire landscape of oscillatory dynamics and render detection of typical sleep patterns difficult. Yet, sleep is characterized not only by specific EEG waveforms, but also by its circadian organization. In the present study we investigated whether brain dynamics of patients with disorders of consciousness systematically change between day and night. We recorded ~24 h EEG at the bedside of 18 patients diagnosed to be vigilant but unaware (Unresponsive Wakefulness Syndrome) and 17 patients revealing signs of fluctuating consciousness (Minimally Conscious State)...

The paper discusses how the condition of crossed-eyes affects a baby's eye contact with mother and potentially results in the loss of a vital emotional connection with her during the earliest days of life. This loss may contribute to a rupture that arrests emotional development at a deep psychic level. It is suggested that, in the same way as premature separation, the rupture can precipitate a 'fusional complex', a defence that develops to protect the infant against psychotic anxieties. The paper proposes that psychological development atrophies in this place and creates a blind spot...

OBJECTIVE: To evaluate effects of 5 sessions of transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex in patients with prolonged disorders of consciousness (DOC). METHODS: Seven patients in vegetative state (VS) and 6 in minimally conscious state (MCS), at ≥3months after brain injury, were randomized into two groups: group 1 received one week of active tDCS and 1week of sham stimulation, separated by 1 resting week; group 2 received active and sham stimulation in reverse order...

OBJECTIVE: We aimed to elucidate whether 40Hz auditory steady-state response (ASSR) could be sensitive to the state of patients with disorders of consciousness (DOC) as estimated with Coma Recovery Scale-Revised (CRS-R) diagnostic tool. METHODS: Fifteen DOC patients and 24 healthy controls took part in the study. The 40Hz click trains were used to evoke ASSRs. Mean evoked amplitude (EA) and phase-locking index (PLI) within 38-42Hz window were calculated for 100ms bins, starting from -200 to 700ms relative to stimulus onset...

OBJECTIVE: Psychogenic nonepileptic seizures (PNES) are abrupt, paroxysmal changes in behavior or consciousness that may phenomenologically resemble epileptic seizures. Given the known association between anxiety and PNES, we hypothesized that in these subjects there may be evidence that the nervous system is hypersensitive to external stimuli. We aimed to test our hypothesis by means of the auditory startle reaction (ASR). By investigating ASR, we also had the opportunity to test presence of orienting reaction, which is generally defined as the second phase of response after the auditory stimulus, with longer latency...

Cognitive therapy for social anxiety disorder (SAD) based on the Clark and Wells model emphasizes negative beliefs about the social self and self-consciousness as central causal factors. However, Wells' metacognitive model proposes that metacognitive beliefs are central to pathology universally. The relative importance of cognitive and metacognitive beliefs in the treatment of SAD is therefore an important research question. This study examined change in negative cognitive and negative metacognitive beliefs as independent correlates of symptom improvement in 46 SAD patients undergoing evidence-based treatments...

Depersonalization disorder (DPD) is a debilitating dissociative condition with no proven treatments. Although the pathophysiology of DPD is poorly understood, there are reports of increased excitability of the prefrontal cortex in patients with this condition. The temporo-parietal junction may also play a major role in the conscious experience of the spatial unity of the normal self and body. Repetitive transcranial magnetic stimulation has been shown in some case studies to effectively treat this condition...

The description of coma and coma arousal therapy in Caraka Saṁhitā is described in sṁtra 24, verses 42-53. It describes the definition of coma, differential diagnosis of coma from other disorders of consciousness, signs of coma, etiology of coma, coma arousal therapy, and emergence from coma. The similarities and differences of these aspects of coma from the perspective of its interpretation in modern medicine are discussed in this article.

Self-conscious emotions, such as guilt, shame, or self-disgust, as well as self-related motives, such as self-enhancement or self-verification, influence how people perceive, evaluate, memorize, and respond to self-related information. They not only influence peoples' concepts of themselves but may also affect their behavior in social environments. In the current review, we describe alterations of self-related processing in borderline personality disorder (BPD). We chose BPD as an example of a mental disorder of which impairments in self-functioning and identity constitute a major feature...

PURPOSE: Sedation is becoming more commonplace for pediatric patients undergoing minor procedures. Fortunately, electronic monitors have contributed to a reduction in the associated respiratory adverse events (RAEs). To test the hypothesis that adding the pretracheal stethoscope (PTS) to standard monitoring methods (SMMs) may improve RAE detection in sedated pediatric dental patients, the frequency of RAEs detected by SMMs (i.e. visual observation, capnography, and pulse oximetry) was compared to that detected by SMMs alongside continuous PTS auscultation...

Optokinetic nystagmus (OKN), the reflexive eye movements evoked by a moving field, has recently gained interest among researchers as a useful tool to assess conscious perception. When conscious perception and stimulus are dissociated, such as in binocular rivalry-when dissimilar images are simultaneously presented to each eye and perception alternates between the two images over time-OKN correlates with perception rather than with the physical direction of the moving field. While this relationship is well established in healthy subjects, it is yet unclear whether it also generalizes to clinical populations, for example, patients with Parkinson's disease...

Awareness generation and modulation may depend on a balanced information integration and differentiation across default mode network (DMN) and external awareness networks (EAN). Neuromodulation approaches, capable of shaping information processing, may highlight residual network activities supporting awareness, which are not detectable through active paradigms, thus allowing to differentiate chronic disorders of consciousness (DoC). We studied aftereffects of repetitive transcranial magnetic stimulation (rTMS) by applying graph theory within canonical frequency bands to compare the markers of these networks in the electroencephalographic data from 20 patients with DoC...

REVIEW
Nicole K Y Tang
Cognitive Behavioural Therapy (CBT) is a form of evidence-based talking therapy that emphasises the importance of behaviour and conscious thoughts in shaping our emotional experiences. As pain becomes increasingly accepted as not only a sensory but also an emotional experience, success in using CBT to treat emotional disorders has resulted in the incorporation of cognitive-behavioural principles into the management of chronic pain. Outcomes of CBT-informed interdisciplinary pain management programmes are modest at best, despite rapid methodological improvements in trial design and implementation...

Pain assessment in patients with disorders of consciousness (DoC) is a controversial issue for clinicians, who require tools and standardised procedures for testing nociception in non-communicative patients. The aims of the present study were, first, to analyse the psychometric properties of the Italian version of the Nociception Coma Scale and, second, to evaluate pressure pain thresholds in a group of patients with DoC. The authors conducted a multi-centre study on 40 healthy participants and 60 DoC patients enrolled from six hospitals in Italy...

The JFK Coma Recovery Scale-Revised (JFK CRS-R), a behavioral scale, is often used for clinical assessments of patients with disorders of consciousness (DOC), such as patients in a vegetative state. However, there has been a high rate of clinical misdiagnosis with the JFK CRS-R because patients with severe brain injures cannot provide sufficient behavioral responses. It is particularly difficult to evaluate the communication function in DOC patients using the JFK CRS-R because a higher level of behavioral responses is needed for communication assessments than for many other assessments, such as an auditory startle assessment...

Psychedelic drugs have historically been used for ritualistic purposes and to help individuals gain insight. Ibogaine, a naturally occurring psychoactive substance, has been reported to have anti-addictive properties that aid in the treatment of substance use disorders. An online survey obtained retrospective data from individuals who used ibogaine in the past. Individuals who used ibogaine tended to describe thematically similar experiences post-treatment. This study adds to the literature by using the 5d-ASC, a psychometrically sound measure of altered states of consciousness (ASCs), to examine the ASCs induced by ibogaine and discusses the demographic characteristics of those who seek ibogaine treatment (N = 27)...

BACKGROUND: Although the recreational use of psychoactive substances is common there is only limited systematic collection of data on acute drug toxicity or hospital presentations. Currently, data from Switzerland are only available from the University Hospital of Basel. The present study aimed to describe the presentations due to recreational drug use at an emergency department in Bern, Switzerland during a 4 year period. METHODS: Retrospective analysis of cases presenting from May 2012 to April 2016 at the emergency department of the University Hospital of Bern, Switzerland, with symptoms/signs consistent with acute toxicity of recreational drug use...

It has been argued that disorders in body-ownership and aberrant experiences in self-consciousness are due to biases in multisensory integration. Here we examine whether such biases are also associated with spontaneous out-of-body experiences (OBEs) in a nonclinical population. One-hundred and 80 participants took part in a rubber hand illusion (RHI) experiment with synchronous and asynchronous visual and tactile stimulation. A realistic threat was delivered to the rubber hand after a fixed period of stimulation...
