Evolution of psychological condition in caregivers of patients with disorders of consciousness: a longitudinal study

Mood assessments of family caregivers of patients with severe brain injury in China

OBJECTIVES

Long-term care of severe brain injury patients places a significant mental burden on family caregivers, yet few studies have reported the situation in China. We aimed to describe the mood states of family caregivers of patients with severe brain injury and examine the influencing factors that affect caregivers' moods.

METHODS

Cross-sectional survey was used to assess the mood profiles of Chinese family caregivers between February 2019 and February 2020. Demographic data of caregivers and patients, the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder scale (GAD-7) were used to assess the level of depressive and anxiety symptoms. The quality of life score was also assessed by a visual analog scale, and the Coma Recovery Scale-Revised was used to assess the patient's consciousness.

RESULT

One hundred and one patients with severe brain injury (57 unresponsive wakefulness syndrome, UWS) between the age of 14 and 70 and their main family caregivers were enrolled in the study. Most caregivers displayed depressive (n = 62) and anxiety symptoms (n = 65), with 17 and 20 of these family caregivers reporting (moderately) severe depressive symptom and severe anxiety symptom, respectively. The caregiver's depressive symptom level significantly decreased as the patient's injury lasted longer (r =  - 0.208, P = 0.037). Moreover, the age of the patient negatively related to the levels of depressive (r =  - 0.310, P = 0.002) and anxiety symptoms (r =  - 0.289, P = 0.003) in caregivers. There was a significant positive correlation between anxiety and depressive symptoms scores in family caregivers (r = 0.838, P < 0.001). The higher the level of anxiety (r =  - 0.273, P = 0.006) and depressive symptoms (r =  - 0.265, P = 0.007), the worse the quality of life.

CONCLUSION

Many family caregivers of patients with severe brain injury experience various levels of anxiety and depressive symptoms in China. Tailor-made psychological help seems imperative. Researchers and doctors can provide information about patient's conditions to assist family members in discussing rehabilitation options for patients in different states of consciousness will help to ease anxiety of family caregivers.

Research considerations for prospective studies of patients with coma and disorders of consciousness

Disorders of consciousness are neurological conditions characterized by impaired arousal and awareness of self and environment. Behavioural responses are absent or are present but fluctuate. Disorders of consciousness are commonly encountered as a consequence of both acute and chronic brain injuries, yet reliable epidemiological estimates would require inclusive, operational definitions of the concept, as well as wider knowledge dissemination among involved professionals. Whereas several manifestations have been described, including coma, vegetative state/unresponsive wakefulness syndrome and minimally conscious state, a comprehensive neurobiological definition for disorders of consciousness is still lacking. The scientific literature is primarily observational, and studies-specific aetiologies lead to disorders of consciousness. Despite advances in these disease-related forms, there remains uncertainty about whether disorders of consciousness are a disease-agnostic unitary entity with a common mechanism, prognosis or treatment response paradigm. Our knowledge of disorders of consciousness has also been hampered by heterogeneity of study designs, variables, and outcomes, leading to results that are not comparable for evidence synthesis. The different backgrounds of professionals caring for patients with disorders of consciousness and the different goals at different stages of care could partly explain this variability. The Prospective Studies working group of the Neurocritical Care Society Curing Coma Campaign was established to create a platform for observational studies and future clinical trials on disorders of consciousness and coma across the continuum of care. In this narrative review, the author panel presents limitations of prior observational clinical research and outlines practical considerations for future investigations. A narrative review format was selected to ensure that the full breadth of study design considerations could be addressed and to facilitate a future consensus-based statement (e.g. via a modified Delphi) and series of recommendations. The panel convened weekly online meetings from October 2021 to December 2022. Research considerations addressed the nosographic status of disorders of consciousness, case ascertainment and verification, selection of dependent variables, choice of covariates and measurement and analysis of outcomes and covariates, aiming to promote more homogeneous designs and practices in future observational studies. The goal of this review is to inform a broad community of professionals with different backgrounds and clinical interests to address the methodological challenges imposed by the transition of care from acute to chronic stages and to streamline data gathering for patients with disorders of consciousness. A coordinated effort will be a key to allow reliable observational data synthesis and epidemiological estimates and ultimately inform condition-modifying clinical trials.

COVID-19 and hospital restrictions: physical disconnection and digital re-connection in disorders of consciousness

Purpose: The coronavirus disease 2019 (COVID-19) pandemic forced hospitals to adopt tighter restrictions, the most impacting is no access to visitors. Disorder of consciousness (DOC) due to severe acquired brain injury is a condition needing neurorehabilitation and the role of relatives is essential, hence besides physical "disconnection" digital "re-connection" is crucial. We aimed to assess whether digital communication benefits in patients with DOC, considering the sensorial and emotional deprivation due to the COVID-19 emergency lock-down.Methods: For eleven consecutive patients with DOC admitted to our Intensive Neurorehabilitation Care (mean age: 45; females: 9), two observers registered neurobehavioral changes during a video-calls with their relatives. Heart-rate variability was measured before and during the calls. The video-call was performed by using two displays of different sizes: tablet (T-video-call) and large screen (LS-Video-call).Results: The video-calls impacted on the patients' vigilance and in the relationship with relatives. Moreover, positively impacted on their relatives. The current results showed significant greater impact on patients during the LS-video-call than when they are exposed to T-video-call.Conclusions: During the COVID-19 pandemic, besides the physical disconnection to stop the contagion spread, a "digital re-connection" is needed for all and especially for fragile population groups as patients with DOC.

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.

'Online therapy' to reduce caregiver's distress and to stimulate post-severe acquired brain injury motor and cognitive recovery: A Sicilian hospital experience in the COVID era

INTRODUCTION

Severe acquired brain injury(SABI) often results in the deterioration of physical, cognitive and emotional functions in the patient and a significant caregiver's distress syndrome, which is now amplified by the social isolation, depression and financial difficulties related to the COVID-19 pandemic. The use of web-based online-therapy has been shown to be useful to overcome caregiver's distress syndrome and further stimulate cognitive-motor recovery of SABI-patients. Our study aimed to investigate whether a systematic online Skype-therapy(OLST) may be of support in favoring global cognitive and sensory-motor recovery in SABI-patients and reducing caregiver distress.

METHODS

Twenty-five SABI-subjects in inpatient regimen were provided with intensive OLST with the caregiver for 12 weeks in addition to standard neurorehabilitation. Each subject and caregiver was evaluated before and after the treatment by administering an ad hoc battery. Furthermore, 18 of 27 patients were provided with EEG recording in resting state.

RESULTS

We found a significant reduction in caregiver's anxiety (p<0.0001) and burden(p<0.0001). Patients showed significant improvement in trunk control (p<0.0001), functional independence (p = 0.005), functional (p = 0.01) and global communication (p = 0.004), cognitive functioning (p = 0.001), and behavioral responsiveness (p = 0.0004). The training yielded a significant connectivity change within the fronto-centro-parietal areas in the delta frequency band (p<0.0001) and the centro-parieto-occipital areas in the alpha range (p = 0.004).

DISCUSSION

OLST may be a useful and complementary treatment to optimize global cognitive and functional recovery in SABI-subjects and reduce caregivers' concerns in the Covid-era. OLST can foster cognitive-motor recovery potentially by favoring the plasticity-dependent functional recovery. Therefore, OLST could be proposed as a tool allowing social conversations also in the hospital setting.

Psychological status and role of caregivers in the neuro-rehabilitation of patients with severe Acquired Brain Injury (ABI)

OBJECTIVE

To investigate the relationships between (a) the psychological status of the caregiver, (b) the specific features of caregiving as perceived by the cognitive therapist in neuro-rehabilitation, (c) the caregivers' subjective approach to neuro-rehabilitation, and (d) the functional outcome of the patient.

METHODS

Twenty-four patients with severe acquired brain injury and their 24 caregivers participated in this observational study. Caregivers underwent a psychological assessment examining emotional distress, burden and family strain; their subjective approach to neuro-rehabilitation has been evaluated by two specific answers. The patients' cognitive therapists responded to an ad-hoc questionnaire, namely the "Caregiving Impact on Neuro-Rehabilitation Scale" (CINRS), evaluating the features (i.e., amount and quality) of caregiving. Finally, the functional outcome of the patient was assessed through standardized scales of disability and cognitive functioning.

RESULTS

The caregivers' psychological well-being was associated to the features of caregiving, to the subjective approach to neuro-rehabilitation, and to the functional recovery of their loved ones. A better caregivers' approach to neuro-rehabilitation was also associated to an overall positive impact of caregiving in neuro-rehabilitation and to a better functional outcome of the patients.

CONCLUSIONS

We posited a virtuous circle involving caregivers within the neuro-rehabilitation process, according to which the caregivers' psychological well-being could be strictly associated to a better level of caregiving and to a better functional outcome of the patients that, in turn, could positively influence the caregivers' psychological well-being. Although preliminary, these results suggest a specific psycho-educational intervention, aimed at improving the caregivers' psychological well-being and at facilitating their caring of the loved one.

Factors related to cognitive reserve among caregivers of severe acquired brain injury

Stroke is one of the severe cause of motor and cognitive disabilities. These type of disabilities occurred a strong impact on whole family system. Caregiver burden may determine in relatives of patients with brain injury a decreasement of mental and physical health. The present study aims to better clarify the mechanism through which chronic stress influence caregivers' cognitive functioning and how the psychological and cognitive resources may represent as a predictive factor. Caregivers were submitted to neuropsychological tests that evaluated level of mental health ad level of burden. Our results showed a significant correlation between cognitive reserve and self-efficacy skills in health care of patients. Findings suggested that the caregiver burden and the level of general distress influenced the cognitive performance. An improvement of cognitive functions is associated with a reduction of self-efficacy skills, causing a caregiver burden improvement.

Caregivers of people with disorders of consciousness: which burden predictors?

OBJECTIVES

Caregivers of patients diagnosed with disorders of consciousness (DoCs) play a pivotal role in the care pathway of these patients. Due to the high costs of care, among other symptoms and disorders previously described in the literature, they can manifest also mood and stress-related disorders which greatly impact their life and increase their burden. It is noteworthy to identify which factors are better related to the manifestation of mood and stress-related disorders to care for the caregivers in time. However, no studies have explored which factors are related to the manifestation of these disorders within this population yet.

MATERIALS AND METHODS

We explored with different questionnaires whether patient-, caregiver-, and caregiving environment-related factors are associated with mood and stress-related disorders on 114 caregivers of patients with DoCs.

RESULTS

Our results showed that female caregivers manifested higher levels of both depression and prolonged grief disorder; furthermore, the presence of economic problems increased the levels of depression. Moreover, different levels of caregivers' depression, anxiety, anger expression, and prolonged grief disorder were closely linked to the degree of behavioural responsiveness of the patients.

CONCLUSIONS

Our results highlighted the need to consider also caregivers' mood and stress-related disorders when defining the care pathway of patients with DoCs; indeed, caregivers constitute the main environment of DoC patients and they need tailored interventions aimed at reducing their burden due to caregiving.

A new tool to assess responsiveness in disorders of consciousness (DoC): a preliminary study on the Brief Post-Coma Scale (BPCS)

INTRODUCTION

The Brief Post-Coma Scale (BPCS) is an easy diagnostic tool for individuals with disorders of consciousness (DoC), in a reduced version from a previously Post-Coma Scale, that could distinguish patients in the minimally conscious state (MCS) from those in unresponsive wakefulness syndrome (UWS), formerly defined as vegetative state (VS).

OBJECTIVE

Aim of the study was to assess the diagnostic validity of the BPCS in comparison with the Coma Recovery Scale-Revised (CRS-R), in its Italian validated version, the Disability Rating Scale (DRS), the Level of Cognitive Functioning (LCF), and the Glasgow Outcome Scale (GOS).

METHODS

In an Italian multicenter study on 545 patients with DoC, 36 post-acute rehabilitation wards, 32 long-term care centers, and 2 family associations participated to data collection.

RESULTS

Statistically significant correlations were found between the BPCS and the other clinical scales: R = 0.586 (p < 0.001) with LCF, R = - 0.566 (p < 0.001) with DRS, R = 0.622 (p < 0.001) with CRS-R. The BPCS scores resulted significantly correlated with the time from acute event (R = 0.117, p = 0.006). Patients with GOS score 2 had mean BPCS of 1.84 ± 1.19, whereas those with GOS 3 had significantly higher scores 3.88 ± 1.71 (p < 0.001). Similarly, in patients with vegetative state/UWS (VS/UWS), the mean BPSC score was 1.71 ± 1.09, significantly lower (p < 0.001) than that of patients with minimally conscious state (BPCS = 3.83 ± 1.29). Finally, the agreement of the BPCS and clinical diagnosis was of 84.4%, with an odds ratio OR = 3.781 (95% CI = 3.026-4.725, p < 0.001).

CONCLUSIONS

The BPCS has demonstrated statistically significant correlations with the most commonly used scales in persons with DoC.

Assessment of the mental health of carers according to the stage of patients with diagnosis of Alzheimer-type dementia

In this study, the aims were to assess the mental health state of carers for patients with Alzheimer-type dementia (AD) according to stage of disease and to collect data with the aim of determining precautions to reduce the load of the patient and disease on the carer. The study included 120 patients with stages determined, according to the clinical dementia rating scale (CDR), and 120 patient relatives above the age of 18 who cared for these patients every day, for the whole day or part of the day, and who accepted participation in the research. This prospective and cross-sectional study performed a detailed neurological examination of patients, and after completing the "personal information form" with the interviewer, each patient had CDR and mini-mental test (MMSE) applied to determine stage of dementia and physical state. Carers first completed the "personal information form" and then had the short symptom inventory (SSI) applied. According to the stage of patients, there were significant differences determined in the points for all sub-scales belonging to the SSI of carers. As the disease stage increased, all sub-scale points for the SSI increased. With the transition of disease stages from 0.5-1 to stage 2, from stage 2 to 3, and with the inverse reduction in MMT scores, the points obtained by carers on the SSI sub-scales increased. This data shows that with progressing disease stage, the load on the carer increases and mental health begins to dysfunction.
