Filter by:Disentangling the vegetative state from the minimally conscious state is often difficult when relying only on behavioral observation. In this study, the investigators explored a new event-related potential paradigm as an alternative method for the detection of voluntary brain activity and cognitive abilities in the patients with disorders of consciousness.
The aim of the present study was to evaluated the neural effect of music on the cerebral activation in unresponsive wakefulness syndrome (UWS) and minimally conscious state (MCS) by using functional magnetic resonance imaging (fMRI).

In this study, high-resolution brain functional magnetic resonance imaging (MRI) was used to evaluate the differences in brain structure and brain function network between patients with different degrees of disturbance of cognition and healthy controls by means of cohort follow-up and control study. The changes of patients' The dynamic changes of learning, to explore its clinical value as an early diagnosis. Combined with neurobehavioral scales and high-resolution brain structure, functional magnetic resonance imaging data to assess the brain structure, functional characteristics and consciousness of patients with impaired consciousness, and initially establish awareness of patients with recovery of consciousness Predictable imaging signs. Twenty eligible controls, 20 VS patients, and 20 MCS patients will be considered for inclusion in the inclusion / exclusion criteria. Informed consent will be obtained as required before starting any registration process.
In recent years, promoting wakening attempts in patients with disorders of consciousness are increasing, but there are a lack of objective indicators to evaluate the efficacy and further researches on the brain mechanism during the wakening processing. So, the study first assessed the cerebral response during emotional acoustic stimuli with quantitative EEG and ERP(Event-related potential), and next, the investigators explored the relationship between brain activation and patients' recovery.
Transcranial magnetic stimulation involves the use of alternating magnetic fields to stimulate neurons in the brain.To date, several studies have focused on the use of TMS in patients with impaired consciousness.However,its therapeutic effects have been variously documented.So,in this study ,investigators explore the effects of rTMS with cross-over design.
The present observational study is aimed at reporting the short-, mid- and long-term outcomes of patients with Disorder of Consciousness (DOC), in Vegetative State (VS) or Minimally Conscious State (MCS), due to a severe Acquired Brain Injury (sABI), after repeated treatments with anodal Transcranial Direct Current Stimulation (tDCS) on Left Dorsolateral Prefrontal Cortex (L-DLPFC), to stimulate recovery of consciousness. The results obtained will also be compared with those of a historical control cohort, before the introduction of tDCS, matched for demographic and clinical characteristics.
There is practical evidence but no scientific investigations that persons with severe disorders of consciousness can profit from animal-assisted therapy regarding their level of awareness. The aim of this study is to investigate the effect of animal-assisted therapy on brain activity of inpatients at REHAB Basel with severe disorders of consciousness. To do so, the frontal brain activity of 20 the inpatients at REHAB Basel in a minimally conscious state is investigated via near-infrared spectroscopy (NIRS). Moreover, 20 healthy participants are included as control subjects.
This study aims to explore autonomic cardiovascular regulation, through measures of heart rate variability (HRV), during different passive and active activities in patients with severe acquired brain injury and a low conscious state. Data from active rehabilitation will be compared with passive periods of rest as well as nightly variance during a continuous 5-day period.
In this randomized, double-blind, placebo controlled project, the investigators would like to assess the effect of a specific light, as compared to placebo light, on wakefulness (circadian rhythms, homeostasy, sleep-wake cycle), awareness (perceptual and self consciousness), cognition (attention, memory) and underlying brain activity (electrophysiology and neuroimaging)
