Minimally conscious state plus versus minus: Likelihood of emergence and long-term functional independence.

OBJECTIVE: Severe brain injuries can result in disorders of consciousness, such as the Minimally Conscious State (MCS), where individuals display intermittent yet discernible signs of conscious awareness. The varied levels of responsiveness and awareness observed in this state have spurred the progressive delineation of two subgroups within MCS, termed "plus" (MCS+) and "minus" (MCS-). However, the clinical validity of these classifications remains uncertain. This study aimed to investigate and compare the likelihood of emergence from MCS, as well as the functional independence after emergence, in individuals categorized as in MCS+ and MCS-. METHODS: Demographic and behavioral data of 80 participants, admitted as either in MCS+ (n = 30) or MCS- (n = 50) to a long-term neurorehabilitation unit, were retrospectively analyzed. The neurobehavioral condition of each participant was evaluated weekly until discharge, demise, or emergence from MCS. The functional independence of those participants who emerged from MCS was assessed 6 months after emergence. RESULTS: While only about half of the individuals classified as in MCS- (n = 24) emerged from the MCS, all those admitted as in MCS+ did, and in a shorter postinjury period. Despite these differences, all individuals who emerged from the MCS demonstrated similar high disability and low functional independence 6 months after emergence, regardless of their state at admission. INTERPRETATION: Individuals classified as MCS+ exhibited a higher likelihood of emergence and a shorter time to emergence compared to those in MCS-. However, the level of functional independence 6 months after emergence was found to be unrelated to the initial state at admission.

Neuro-orthopaedic assessment and management in patients with prolonged disorders of consciousness: A review.

BACKGROUND: Following a severe acquired brain injury, neuro-orthopaedic disorders are commonplace. While these disorders can impact patients' functional recovery and quality of life, little is known regarding the assessment, management and treatment of neuro-orthopaedic disorders in patients with disorders of consciousness (DoC). OBJECTIVE: To describe neuro-orthopaedic disorders in the context of DoC and provide insights on their management and treatment. METHODS: A review of the literature was conducted focusing on neuro-orthopaedic disorders in patients with prolonged DoC. RESULTS: Few studies have investigated the prevalence of spastic paresis in patients with prolonged DoC, which is extremely high, as well as its correlation with pain. Pilot studies exploring the effects of pharmacological treatments and physical therapy show encouraging results yet have limited efficacy. Other neuro-orthopaedic disorders, such as heterotopic ossification, are still poorly investigated. CONCLUSION: The literature of neuro-orthopaedic disorders in patients with prolonged DoC remains scarce, mainly focusing on spastic paresis. We recommend treating neuro-orthopaedic disorders in their early phases to prevent complications such as pain and improve patients' recovery. Additionally, this approach could enhance patients' ability to behaviourally demonstrate signs of consciousness, especially in the context of covert awareness.

Medical comorbidities in patients with prolonged disorder of consciousness: A narrative review.

BACKGROUND: A few studies specifically addressed medical comorbidities (MCs) in patients with severe acquired traumatic or non-traumatic brain injury and prolonged disorders of consciousness (pDoC; i.e., patients in vegetative state/unresponsive wakefulness syndrome, VS/UWS, or in minimally conscious state, MCS). OBJECTIVE: To provide an overview on incidence of MCs in patients with pDoC. METHODS: Narrative review on most impacting MCs in patients with pDoC, both those directly related to brain damage (epilepsy, neurosurgical complications, spasticity, paroxysmal sympathetic hyperactivity, PSH), and those related to severe disability and prolonged immobility (respiratory comorbidities, endocrine disorders, metabolic abnormalities, heterotopic ossifications). RESULTS: Patients with pDoC are at high risk to develop at least one MC. Moderate or severe respiratory and musculoskeletal comorbidities are the most common MCs. Epilepsy and PSH seem to be more frequent in patients in VS/UWS compared to patients in MCS, likely because of higher severity in the brain damage in VS. Endocrine metabolic, PSH and respiratory complications are less frequent in traumatic etiology, whereas neurogenic heterotopic ossifications are more frequent in traumatic etiology. Spasticity did not significantly differ between VS/UWS and MCS and in the three etiologies. MCs are associated with higher mortality rates, worse clinical improvement and can impact accuracy in the clinical diagnosis. CONCLUSIONS: The frequent occurrence of several MCs requires a specialized rehabilitative setting with high level of multidisciplinary medical expertise to prevent, appropriately recognize and treat them. Comprehensive rehabilitation could avoid possible progression to more serious complications that can negatively impact clinical outcomes.

Should Consistent Command-Following Be Added to the Criteria for Emergence From the Minimally Conscious State?

OBJECTIVE: To determine whether consistent command-following (CCF) should be added to the diagnostic criteria for emergence from the minimally conscious state (eMCS). DESIGN: Retrospective cohort study. SETTING: Inpatient rehabilitation hospital. PARTICIPANTS: Patients (N=214) with acquired brain injury resulting in disorders of consciousness (DoC) admitted to a specialized rehabilitation program. MAIN OUTCOME MEASURES: Difference between time to recovery of CCF and time to recovery of functional object use (FOU) or functional communication (FC), the 2 existing criteria for eMCS as measured by the Coma Recovery Scale-Revised (CRS-R). RESULTS: Of 214 patients (median age, 53 years [interquartile range {IQR}, 34-66 years], male: 134 [62.6%], traumatic etiology: 115 [53.7%], admission CRS-R total score: 10 [IQR, 7-13]) admitted to rehabilitation without CCF, FOU, or FC, 162 (75.7%) recovered CCF and FOU or FC during the 8-week observation period. On average, recovery of CCF, FOU, and FC was observed within 1 day of one another, approximately 46 days (IQR, 38.25-58 days) post injury. One hundred and sixteen patients (71.6%) recovered FOU or FC prior to or at the same time as CCF. CONCLUSIONS: In patients recovering from DoC, CCF reemerges around the same time as FOU and FC. This finding may reflect the shared dependency of these behaviors on cognitive processes (eg, language comprehension, attention, motor control) that are essential for effective interpersonal interaction and social participation. Our results support the addition of CCF to the existing diagnostic criteria for eMCS, but further validation in an independent sample should be conducted.

Improving motor and cognitive recovery following severe traumatic brain injury using advanced emotional audio-video stimulation: Lessons from a case report.

RATIONALE: It is estimated that about 6 million people suffer from severe traumatic brain injury (TBI) each year (73 cases per 100,000 people). TBI may affect emotional, sensory-motor, cognitive, and psychological functions with a consequent worsening of both patient and his/her caregiver's quality of life. In recent years, technological innovations allowed the development of new, advanced sensory stimulation systems, such as Neurowave, to further stimulate residual cognitive abilities and, at the same time, evaluate residual cognition. PATIENT CONCERN: An 69-year-old Italian man entered our neurorehabilitation unit with a diagnosis of minimally conscious state following severe TBI. He breathed spontaneously via tracheostomy and was fed via percutaneous gastrostomy. At the neurological examination, the patient showed severe tetraparesis as he showed fluctuating alertness and responsiveness to external stimuli and opened the eyes without stimulation. DIAGNOSIS: Patient was affected by subarachnoid hemorrhage and frontotemporal bilateral hematoma, which were surgically treated with decompressive craniotomy and subsequent cranioplasty about 6 months before. INTERVENTIONS: The patient underwent a neuropsychological and clinical evaluation before (T0) and after a conventional rehabilitation cycle (T1), and after a Neurowave emotional stimulation-supported rehabilitative cycle (T2). OUTCOMES: Following conventional rehabilitation (T1), the patient achieved a partial improvement in behavioral responsiveness; there was also a mild improvement in the caregiver's distress. Conversely, Neurowave emotional stimulation session determined (at T2) a significant improvement of the patient's behavioral responsiveness, cognition, and in the caregiver's distress. The P300 recording in response to the NES showed a significant change of P300 magnitude and latency. DISCUSSION: Our data suggest that emotional-integrated sensory stimulation using adequate visual stimuli represents a beneficial, complementary rehabilitative treatment for patients in minimally conscious state following a severe TBI. This may occur because stimuli with emotional salience can provide a reliable motivational resource to stimulate motor and cognitive recovery following severe TBI.

Baclofeno intratecal en daño cerebral y recuperación de estado vegetativo persistente. A propósito de un caso / Intrathecal baclofen therapy in brain injury and recovery of persistent vegetative state. Apropos of a case

Pacientes con daño cerebral y espasticidad son candidatos a terapia de baclofeno intratecal (ITB) cuando dosis máximas de antiespásticos orales no son efectivas. Algunos autores describen una mejora en el nivel de consciencia en pacientes con daño cerebral y alteraciones del nivel de consciencia. Presentamos el caso de una paciente de 43 años con daño cerebral, espasticidad y estado vegetativo persistente que presentó mejora del nivel de consciencia tras administrar ITB para el manejo de la espasticidad. Durante la prueba de infusión de baclofeno intratecal monitorizamos la espasticidad según la Escala modificada de Ashworth y el nivel de consciencia mediante Coma Recovery Scale-Revised. Tras observar mejoría en Escala modificada de Ashworth y en Coma Recovery Scale-Revised, decidimos implantar la bomba de ITB y la paciente emergió de estado vegetativo persistente a estado de mínima consciencia. Sugerimos el beneficio añadido de ITB sobre el nivel de consciencia en pacientes con daño cerebral, alteraciones del nivel de consciencia y espasticidad, no existiendo evidencia suficiente para prescribirlo en el tratamiento de alteraciones del nivel de consciencia

Patients with brain injury and spasticity are candidates for intrathecal baclofen therapy (ITB) when maximal doses of oral antispastic drugs fail. Some authors have described an improvement in the level of consciousness in patients with brain injury and disorder of consciousness treated with ITB for spasticity. We present the case of a 43-year-old patient with brain injury, spasticity, and permanent vegetative state (PVS) who showed an improvement in the level of consciousness after ITB for spasticity. We performed an ITB infusion test, assessing the spasticity with the Modified Ashworth Scale (MAS) and level of consciousness with the Coma Recovery Scale-Revised (CRS-R) and observed an improvement in the spasticity and the level of consciousness. Consequently, the ITB pump was implanted and the patient recovered from PVS to minimal conscious state (MCS). We conclude that ITB is indicated in patients with brain injury and spasticity. We suggest the improvement in the level of consciousness as a possible additional benefit. There is a lack of evidence to recommend ITB in patients with altered level of consciousness

[Midnight-noon ebb-flow acupuncture combined with rehabilitation therapy for severe craniocerebral trauma patients with vegetative state: a randomized controlled trial].

OBJECTIVE: To compare the clinical therapeutic effect of midnight-noon ebb-flow acupuncture combined with rehabilitation therapy and simple rehabilitation therapy in severe craniocerebral trauma patients with vegetative state. METHODS: A total of 100 patients were randomized into an observation group and a control group, 50 cases in each one. Basic treatment of medication, hyperbaric oxygen therapy and specialized nursing were given in both groups. In the control group, rehabilitation therapy was adopted for 30 min each time, once a day. On the basis of the control group, midnight-noon ebb-flow acupuncture was applied in the observation group, the needles were sustained for 30 min, once a day, 5 times a week. The treatment was for 30 days in both groups. Before treatment and after 10, 20, 30 days of treatment, scores of Glasgow coma scale (GCS) and coma recovery scale-revised (CRS-R) were observed, and the conscious rate after treatment was calculated in both groups. RESULTS: Compared before treatment, the GCS and CRS-R scores after 10, 20, 30 days of treatment were increased in both groups (P<0.01), and the scores in the observation group were superior to those in the control group (P<0.01). After treatment, the conscious rate was 20.0% (10/50) in the observation group, which was superior to 12.0% (6/50) in the control group (P<0.01). CONCLUSION: Midnight-noon ebb-flow acupuncture combined with rehabilitation therapy can effectively treat the severe craniocerebral trauma patients with vegetative state, improve the consciousness level, and have superior therapeutic effect compared with simple rehabilitation therapy.

Cognitive impairment, clinical symptoms and functional disability in patients emerging from the minimally conscious state.

BACKGROUND: Although emergence from the minimally conscious state (eMCS) is associated with symptoms including disorientation, memory and attention impairment, restlessness, and significant functional disability, the neurobehavioral profile of eMCS has not been empirically characterized. OBJECTIVE: Determine degree of cognitive impairment, presence of clinical symptoms and functional disability at time eMCS in patients with traumatic and non-traumatic brain injury (TBI, nTBI). METHODS: Retrospective observational study of 169 adults (median [interquartile range] age: 51 [29, 62] years; male: 116; TBI: 103) who emerged from MCS based on the Coma Recovery Scale-Revised while in an inpatient Disorders of Consciousness program. Outcome measures include the Confusion Assessment Protocol (CAP) and Disability Rating Scale (DRS). RESULTS: CAP administration was attempted in 54 subjects. Twenty-eight subjects had valid scores on all CAP items, with a median [interquartile range] of 4 [3-5] symptoms of confusion. Scores in 93% of this subsample were consistent with an acute confusional state. The most common symptoms were cognitive impairment (98% of subjects), disorientation (93%), and agitation (69%). The median DRS score upon emergence from MCS was 14.5 [13, 16], indicating severe disability (n = 140). CONCLUSIONS: eMCS is associated with an acute confusional state and severe disability. This finding may inform the lower boundary of confusion as well as approach to treatment and caregiver education.

When No One Notices: Disorders of Consciousness and the Chronic Vegetative State.

On January 5, 2019, the Associated Press reported that a woman thought to have been in the vegetative state for over a decade gave birth at a Hacienda HealthCare facility. Until she delivered, the staff at the Phoenix center had not noticed that their patient was pregnant. The patient was also misdiagnosed. Misdiagnosis of patients with disorders of consciousness in institutional settings is more the norm than the exception. Misdiagnosis is also connected to a broad and extremely significant change in the understanding of the vegetative state-a change that the field of bioethics has not yet fully taken into account. In September 2018, the American Academy of Neurology, the American College of Rehabilitation Medicine, and the National Institute on Disability, Independent Living, and Rehabilitation Research issued a comprehensive evidence-based review on disorders of consciousness and an associated practice guideline on the care of these patients. These landmark publications update the 1994 Multi-Society Task Force Report on the Vegetative State, which subcategorized the persistent vegetative state as either persistent (once the vegetative state lasted one month) or permanent (once the vegetative state lasted three months after anoxic injury or twelve months after traumatic injury). Noting that 20 percent of patients thought to be permanently unconscious might regain some level of consciousness, the new guideline has eliminated the permanent vegetative state as a diagnostic category, replacing it with the chronic vegetative state.

Looking toward predicting functional recovery in disorders of consciousness: can sensorimotor integration help us?

PRIMARY OBJECTIVE: Only a few objective prognostic markers are available for patients with disorders of consciousness (DoC). We assessed whether the magnitude of short-latency afferent inhibition (SAI) might be a useful predictor of responsiveness recovery and functional outcome in patients with DoC. RESEARCH DESIGN: We enrolled 40 patients with prolonged Minimally Conscious State (MCS) and Unresponsive Wakefulness Syndrome (UWS) in a longitudinal, observational study. METHODS AND PROCEDURES: Clinical features (including Coma Recovery Scale-Revised, CRS-R, and Glasgow Outcome Scale, GOS) and SAI were collected at the study entry and after 18 months from study inclusion, to assess a correlation between SAI and the clinical outcome. MAIN OUTCOMES AND RESULTS: At the follow-up, 19 patients remained in their baseline condition, whereas 7 UWS evolved into MCS or emerged-from-MCS (EMCS), eight MCS evolved into EMCS, and two MCS- evolved into MCS+. Two UWS and one MCS+ died for cardiopulmonary complications. The patients who showed the highest GOS, the highest CRS-R and the lowest SAI strength at study entry, improved at the follow-up. CONCLUSIONS: Our findings suggest that an objective and simple neurophysiologic measure as SAI strength could provide useful information to predict the outcome and the behavioral responsiveness of patients with DoC.

Ethical, Palliative, and Policy Considerations in Disorders of Consciousness.

This essay complements the scientific and practice scope of the American Academy of Neurology Guideline on Disorders of Consciousness by providing a discussion of the ethical, palliative, and policy aspects of the management of this group of patients. We endorse the renaming of "permanent" vegetative state to "chronic" vegetative state given the increased frequency of reports of late improvements but suggest that further refinement of this class of patients is necessary to distinguish late recoveries from patients who were misdiagnosed or in cognitive-motor dissociation. Additional nosologic clarity and prognostic refinement is necessary to preclude overestimation of low probability events. We argue that the new descriptor "unaware wakefulness syndrome" is no clearer than "vegetative state" in expressing the mismatch between apparent behavioral unawareness when patients have covert consciousness or cognitive motor dissociation. We advocate routine universal pain precautions as an important element of neuropalliative care for these patients given the risk of covert consciousness. In medical decision-making, we endorse the use of advance directives and the importance of clear and understandable communication with surrogates. We show the value of incorporating a learning health care system so as to promote therapeutic innovation. We support the Guideline's high standard for rehabilitation for these patients but note that those systems of care are neither widely available nor affordable. Finally, we applaud the Guideline authors for this outstanding exemplar of engaged scholarship in the service of a frequently neglected group of brain-injured patients.

Epidemiological and clinical characteristics of 492 patients in a vegetative state in 29 Italian rehabilitation units. What about outcome?

Recent studies on recovery of consciousness of subjects in a vegetative state (VS) admitted to rehabilitation units have focused mainly on the identification of prognostic factors, whereas few studies have focused on outcome. The aim of this study was to compare demographic and clinical data and report functional outcome of patients in a VS due to severe acquired brain injury (ABI) of different aetiologies. The study was a retrospective multicentre cohort study and involved 492 patients in a VS due to traumatic (TBI) or non-traumatic (NTBI) severe ABI admitted to 29 Italian rehabilitation units. Demographic and clinical data recorded included age, gender, aetiology, Glasgow Coma Scale score; onset-to-admission interval; length of stay in the rehabilitation unit; the department from which they were referred; and the presence of percutaneous endoscopic gastrostomy or tracheostomy. Recovery of consciousness and disability were evaluated using a discharge Disability Rating Scale. At discharge, 53.11% patients had emerged from VS, with TBI subjects significantly more likely to recover consciousness than NTBI ones. Subjects with NTBI had a significantly worse prognosis than those with TBI, and within the NTBI group, subjects with a cerebrovascular aetiology had a better outcome than those with an anoxic aetiology. Among the patients who emerged from VS, 71.30% of TBI and 83.06% of NTBI subjects presented extremely severe disability. Only 37.93% of subjects affected by TBI and 17.44% of those affected by NTBI who presented extremely severe disability returned home after their rehabilitation stay. Even though almost a half of the patients emerged from VS, a large number of these subjects showed severe disability, often making it impossible for them to return home. This situation has a major impact on the healthcare system.

Improvement on the Coma Recovery Scale-Revised During the First Four Weeks of Hospital Stay Predicts Outcome at Discharge in Intensive Rehabilitation After Severe Brain Injury.

OBJECTIVES: To evaluate the prognostic utility of serial assessment on the Coma Recovery Scale-Revised (CRS-R) during the first 4 weeks of intensive rehabilitation in patients surviving a severe brain injury. DESIGN: Prospective cohort study. SETTING: An intensive rehabilitation unit. PARTICIPANTS: Patients (N=110) consecutively admitted to the intensive rehabilitation unit. Inclusion criteria were (1) a diagnosis of unresponsive wakefulness syndrome (UWS) or minimally conscious state (MCS) caused by an acquired brain injury, and (2) aged >18 years. INTERVENTIONS: All patients underwent clinical evaluations using the Italian version of the CRS-R during the first month of hospital stay. MAIN OUTCOME MEASURES: Behavioral classification on the CRS-R and the score on the Glasgow Outcome Scale (GOS) at final discharge. Patients transitioning from UWS to MCS or emergence from MCS (E-MCS), and from MCS to E-MCS were classified as patients with improved responsiveness (IR). RESULTS: After a mean ± SD hospital stay of 5.3±2.7 months, 59 of 110 patients (53.6%) achieved IR. In the multivariable analysis, a higher CRS-R score change at week 4 (odds ratio =1.99; 95% confidence interval [CI], 1.49-2.66; P<.001) was the only significant predictor of IR at discharge. Fifty-three patients (48.2%) were classified as severely impaired at discharge (GOS=3). In the multivariable analysis, higher GOS scores were related to a higher CRS-R score at admission (B=.051; 95% CI, .027-.074; P<.001), a higher CRS-R score change at week 4 (B=.087; 95% CI, .064-.110; P<.001), and an absence of severe infections (B=-.477; 95% CI, -.778 to -.176; P=.002). CONCLUSIONS: An improvement on the total CRS-R score and on different subscales across the first 4 weeks of inpatient rehabilitation discriminates patients who will have a better outcome at discharge, providing information for rehabilitation planning and for communication with patients and their caregivers.

Techniques of cognitive rehabilitation in patients with disorders of consciousness: a systematic review.

Acquired brain injury can produce severe impairments of alertness, cognition, behavior, and, sometimes, an impairment of consciousness. Several studies defined the criteria to distinguish the different level of disorders of consciousness (DOC) and many tools to evaluate awareness, alertness, and response to stimuli were created. The aim of this review is to assess the advanced research of rehabilitative protocols and which rehabilitative techniques are used in the care of DOC patients.

Vegetative state outcomes improved over the last two decades.

OBJECTIVE: To describe late outcomes in patients with prolonged unawareness, and factors affecting them. DESIGN: A retrospective study of 154 patients with traumatic brain injury (TBI) and 52 with non-traumatic brain injury (NTBI), admitted for intensive care and consciousness rehabilitation (ICCR), in a vegetative state (VS) lasting over 1 month. RESULTS: Survival rate (67% total) was higher than in past studies carried out at the same facility (p < 0.01). Consciousness recovery rate (54% total) was higher in NTBI VS patients (p < 0.01) than in earlier cohorts, and similar in TBI VS patients, despite their older age than that of earlier cohorts. No meaningful differences were found in characteristics or in outcomes between the TBI and NTBI groups. Age, length of stay in ICCR, and hydrocephalus were found to affect survival (p < 0.001). Younger age, absence of hydrocephalus, and anti-Parkinsonian medication contributed to consciousness recovery after VS (p < 0.05). CONCLUSIONS: The present study demonstrated an improvement in survival and recovery of consciousness in VS patients over the last two decades, and similar outcomes for both TBI and NTBI VS. Outcomes suggest that acute medical care and ICCR have contributed to advances in VS care.

Late recovery of awareness in prolonged disorders of consciousness -a cross-sectional cohort study.

PURPOSE: To detect any improvement of awareness in prolonged disorders of consciousness in the long term. METHODS: A total of 34 patients with prolonged disorders of consciousness (27 vegetative state and seven minimally conscious state; 16 males; aged 21-73) were included in the study. All patients were initially diagnosed with vegetative/minimally conscious state on admission to our specialist neurological rehabilitation unit. Re-assessment was performed 2-16 years later using Coma Recovery Scale-Revised. RESULTS: Although remaining severely disabled, 32% of the patients showed late improvement of awareness evidenced with development of non-reflexive responses such as reproducible command following and localization behaviors. Most of the late recoveries occurred in patients with subarachnoid hemorrhage (5/11, 45.5%). The ages of patients within the late recovery group (Mean = 45, SD = 11.4) and non-recovery group (Mean = 43, SD = 15.5) were not statistically different (p = 0.76). CONCLUSIONS: This study shows that late improvements in awareness are not exceptional in non-traumatic prolonged disorders of consciousness cases. It highlights the importance of long-term follow up of patients with prolonged disorders of consciousness, regardless of the etiology, age, and time passed since the brain injury. Long-term follow up will help clinicians to identify patients who may benefit from further assessment and rehabilitation. Although only one patient achieved recovery of function, recovery of awareness may have important ethical implications especially where withdrawal of artificial nutrition and hydration is considered. Implications for rehabilitation Long-term regular follow-up of people with prolonged disorders of consciousness is important. Albeit with poor functional outcomes late recovery of awareness is possible in both traumatic and non-traumatic prolonged disorders of consciousness cases. Recovery of awareness has significant clinical and ethical implications especially where withdrawal of artificial nutrition and hydration is considered.

Late-recovery from "permanent" vegetative state in the context of severe traumatic brain injury: A case report exploring objective and subjective aspects of recovery and rehabilitation.

This article provides a detailed outline of the recovery of a young male patient during his emergence from a vegetative state (VS) 19 months after suffering a severe traumatic brain injury. Several similar cases have been documented, but these tend not to consider the subjective experience of the patient or family; our aim was therefore to provide a detailed account that emphasises our neuropsychological exploration of the impact of the injury on this person, and looks at the experience of his mother along the timeline from his accident to the end of a successful period in rehabilitation. Clinical details are presented including standardised and non-standard assessments, neuropsychological interventions, as well as reflections from the patient himself. Moreover, qualitative data from an interview with his mother is used to illustrate the emotional impact on family of such a vacillating diagnostic status and prognosis for the future. We conclude that late-emergence from VS is increasingly documented and further cases must be published to better understand this phenomenon. The present case illustrates the emotional impact this situation can have on a patient and his or her family, and gives an important insight into a patient's view of his or her life and identity following such an event.

Familiar auditory sensory training in chronic traumatic brain injury: a case study.

PURPOSE: The evaluation and treatment for patients with prolonged periods of seriously impaired consciousness following traumatic brain injury (TBI), such as a vegetative or minimally conscious state, poses considerable challenges, particularly in the chronic phases of recovery. METHOD: This blinded crossover study explored the effects of familiar auditory sensory training (FAST) compared with a sham stimulation in a patient seven years post severe TBI. Baseline data were collected over 4 weeks to account for variability in status with neurobehavioral measures, including the Disorders of Consciousness scale (DOCS), Coma Near Coma scale (CNC), and Consciousness Screening Algorithm. Pre-stimulation neurophysiological assessments were completed as well, namely Brainstem Auditory Evoked Potentials (BAEP) and Somatosensory Evoked Potentials (SSEP). RESULTS: Results revealed that a significant improvement in the DOCS neurobehavioral findings after FAST, which was not maintained during the sham. BAEP findings also improved with maintenance of these improvements following sham stimulation as evidenced by repeat testing. CONCLUSIONS: The results emphasize the importance for continued evaluation and treatment of individuals in chronic states of seriously impaired consciousness with a variety of tools. Further study of auditory stimulation as a passive treatment paradigm for this population is warranted. Implications for Rehabilitation Clinicians should be equipped with treatment options to enhance neurobehavioral improvements when traditional treatment methods fail to deliver or maintain functional behavioral changes. Routine assessment is crucial to detect subtle changes in neurobehavioral function even in chronic states of disordered consciousness and determine potential preserved cognitive abilities that may not be evident due to unreliable motor responses given motoric impairments. Familiar Auditory Stimulation Training (FAST) is an ideal passive stimulation that can be supplied by families, allied health clinicians and nursing staff of all levels.

Recovery from vegetative state of patients with a severe brain injury: a 4-year real-practice prospective cohort study.

Patients who have suffered severe traumatic or nontraumatic brain injuries can show a progressive recovery, transitioning through a range of clinical conditions. They may progress from coma to a vegetative state (VS) and/or a minimally conscious state (MCS). A longer duration of the VS is known to be related to a lower probability of emergence from it; furthermore, the literature seems to lack evidence of late improvements in these patients. This real-practice prospective cohort study was conducted in inpatients in a VS following a severe brain injury, consecutively admitted to a vegetative state unit (VSU). The aim of the study was to assess their recovery in order to identify variables that might increase the probability of a VS patient transitioning to MCS. Rehabilitation treatment included passive joint mobilisation and helping/placing patients into an upright sitting position on a tilt table. All the patients underwent a specific assessment protocol every month to identify any emergence, however late, from the VS. Over a 4-year period, 194 patients suffering sequelae of a severe brain injury, consecutively seen, had an initial Glasgow Coma Scale score ≤ 8. Of these, 63 (32.5%) were in a VS, 84 (43.3%) in a MCS, and 47 (24.2%) in a coma; of the 63 patients admitted in a VS, 49 (57.1% males and 42.9% females, mean age 25.34 ± 19.12 years) were transferred to a specialist VSU and put on a slow-to-recover brain injury programme. Ten of these 49 patients were still in a VS after 36 months; of these 10, 3 recovered consciousness, transitioning to a MCS, 2 died, and 5 remained in a VS during the last 12 months of the observation. Univariate analysis identified male sex, youth, a shorter time from onset of the VS, diffuse brain injury, and the presence of status epilepticus as variables increasing the likelihood of transition to a MCS. Long-term monitoring of patients with chronic disorders of consciousness should be adequately implemented in order to optimise their access to rehabilitation services.

Analysis of Italian regulations on pathways of care for patients in a vegetative or minimally conscious state.

Different rehabilitation models for persons diagnosed with disorders of consciousness have been proposed in Europe during the last decade. In Italy, the Ministry of Health has defined a national healthcare model, although, to date, there is a lack of information on how this has been implemented at regional level. The INCARICO project collected information on different regional regulations, analysing ethical aspects and mapping care facilities (numbers of beds and medical units) in eleven regional territories. The researchers found a total of 106 laws; differences emerged both between regions and versus the national model, showing that patients with the same diagnosis may follow different pathways of care. An ongoing cultural shift from a treatment-oriented medical approach towards a care-oriented integrated biopsychosocial approach was found in all the welfare and healthcare systems analysed. Future studies are needed to explore the relationship between healthcare systems and the quality of services provided.
