RESUMO

PURPOSE: To describe the perspective of caregivers about physical therapy (PT) during the COVID-19 pandemic and the effect of social distancing on the health of children with physical disabilities. METHODS: This survey research used a remote questionnaire to identify the perceptions of caregivers about the effect of the COVID-19 pandemic on the health of children and adolescents with physical disabilities and on PT services. Data were analyzed using the frequency of responses; open-ended questions were analyzed through a hybrid approach to thematic analysis. RESULTS: Caregivers of 47 children with cerebral palsy were included. Although most received regular PT services during the pandemic, worsened children's physical conditions and anxiety were prevalent. Caregivers believed that they lacked technical skills. CONCLUSIONS: Social distancing impacted the health of children with physical disabilities, especially their physical conditions. Identifying facilitators and barriers for PT services can be helpful in future similar scenarios.Video abstract Supplemental Digital Content available at:http://links.lww.com/PPT/A503.

RESUMO

BACKGROUND: Older people are the fastest-growing age group, with the highest risk of cognitive impairment. This study assessed the prevalence and associated factors with cognitive impairment in community-dwelling older people. METHODS: Older people were interviewed and accomplished through sociodemographic and health questionnaires. The quantitative variables were described by mean and standard deviation or median and interquartile range. The significance level adopted was 5 % (p < 0.05). The association between the quantitative variables was evaluated using the Pearson or Spearman correlation coefficients. RESULTS: The research population comprised 165 long-lived adults aged ≥80. The youngest one was 80, and the oldest one was 94 years old. The participants were 84.8 ± 3.6 years old, female (63 %) with a mean of education of 2.9 ± 1.8 years. A poor performance in the Mini-Mental State Examination (MMSE) was found in 58 (35.2 %) individuals when adjusted for educational level. After adjustment for confounding factors, body mass index (BMI) (p = 0.09), total older adults' income (up to 1 minimum wage [mw], p = 0.023; over 1 to 2 mw, p = 0.023), functional disability (Moderate dependence 75 %, p = 0.038; Moderate dependence 50 %, p = 0.081; Moderate dependence 25 %, p = 0.054), and the anxiety scale (p = 0.032), remained associated with cognitive impairment. CONCLUSIONS: This study showed that BMI, total older adults' income, functional disability, and anxiety are related to cognitive impairment in long-lived adults. This study has some limitations, such as the fact that it is a cross-sectional study, the reduced number of individuals, and the fact that there were no comparisons among different ages and populations.

RESUMO

AIM: To describe current home participation (frequency, involvement) and caregiver's desire for change in home participation of children and adolescents with Down syndrome, as well as home environmental factors, and to explore the associations of personal and environmental factors with current participation and caregiver's desire for change. METHOD: Eighty-two caregivers (mean age = 45 years 10 months) of children and adolescents with Down syndrome (mean age = 10 years 7 months) were surveyed about the child's home participation and environmental factors using the Participation and Environment Measure-Children and Youth. Furthermore, children's personal and environmental factors were collected. Results are reported using descriptive analysis and correlations (Spearman's rank correlation coefficients and Mann-Whitney U test) to describe the relationship between current participation and caregiver's desire for change, with personal and environmental factors as ordinal and nominal variables respectively (p < 0.05). RESULTS: Children's participation was highest with regard to personal care management and lowest with regard to school-related activities. Most caregivers desired change in homework and household chores. Greater frequency was associated with male sex, caregiver less rigorous social distancing due to the COVID-19 pandemic, and children receiving therapies. Greater involvement was associated with younger age in children and higher environmental support. Older age in children was associated with caregiver's greater desire for change. INTERPRETATION: Personal and environmental factors correlated with participation in specific ways. Creative strategies to promote participation that consider caregiver's wishes should be undertaken.

RESUMO

Gastric squamous cell carcinoma (SCC) is a rare and puzzling entity that challenges conventional paradigms of gastric malignancies, especially in young adults. This case report presents a 22-year-old male with invasive SCC of the stomach, emphasizing the rarity of such occurrences and their diagnostic challenges. The literature review underscores the scarcity of information on gastric SCC, necessitating a critical examination of its clinical implications, etiological factors, and optimal management. The patient's complex medical history, diagnostic journey, and treatment course are detailed, highlighting the importance of multidisciplinary collaboration and advanced diagnostic techniques. Immunohistochemistry is a crucial tool for precise tumor characterization, and the absence of established risk factors emphasizes the enigmatic nature of gastric SCC. This case report contributes to the understanding of gastric SCC, prompting further research into its unique features, etiology, and therapeutic strategies in the context of gastric cancer.

RESUMO

Deep brain stimulation (DBS) is an emerging therapy for treatment-resistant depression (TRD). Although adverse effects have been reported in early-phase and a few randomized clinical trials, little is known about its overall safety profile, which has been assumed to be similar to that of DBS for movement disorders. The objective of this study was to pool existing safety data on DBS for TRD. Following PRISMA guidelines, PubMed was searched for English articles describing adverse outcomes after DBS for TRD. Studies were included if they reported at least 5 patients with a minimal follow-up of 6 months. After abstract (n = 607) and full-article review (n = 127), 28 articles reporting on 353 patients met criteria for final inclusion. Follow-up of the studies retrieved ranged from 12 to 96 months. Hemorrhages occurred in 0.8% of patients and infections in 10.2%. The rate of completed suicide was 2.5%. Development or worsening of depressive symptoms, anxiety, and mania occurred in 18.4%, 9.1%, and 5.1%, respectively. There were some differences between targets, but between-study heterogeneity precluded statistical comparisons. In conclusion, DBS for TRD is associated with surgical and psychiatric adverse events. Hemorrhage and infection occur at rates within an accepted range for other DBS applications. The risk of suicide after DBS for TRD is 2.5% but may not represent a significant deviation from the natural history of TRD. Finally, risks of worsening depression, anxiety, and the incidence of mania should be acknowledged when considering DBS for TRD.

RESUMO

Pain control after deep brain stimulation (DBS) in Parkinson's disease (PD) remains unclear. Following six months, subthalamic (STN)-DBS reduced sensory complaints related to parkinsonism and bodily discomfort, increasing central beta-endorphin level. Pallidal GPi-DBS decreased bodily discomfort and beta-endorphin levels. Unexplained pain by other conditions and bodily discomfort were negatively correlated with beta-endorphin levels. Thus, DBS regulates central opioids, and prioritizing STN is important for PD patients with significant sensory complications.

RESUMO

OBJECTIVE: To characterize the environmental factors of children and adolescents with Cerebral Palsy (CP) in the state of Minas Gerais (MG), Brazil. METHODS: This is a cross-sectional study involving 164 caregivers of children/adolescents with CP, aged 1-14 years. The Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS) were used to classify the participants' functioning, and environmental factors were evaluated by an on-line questionnaire that examined products and technologies, physical environment, services, and systems. A descriptive analysis was performed using percentage and frequency. RESULTS: Most participants had bilateral CP (66.9%) and 45% of them were spastic. Levels II and V of the GMFCS and MACS were the most frequent. About half (49.4%) used anticonvulsants, 27.4% underwent botulinum toxin application, and 29% went through orthopedic surgery in the lower limbs. Among the participants, 71.3% used orthoses in the lower limbs, and 51.8% used the public health care system. Most had access to physiotherapy (91.5%), but found difficulties to access interventions with other professionals, such as psychologists (28%) and nutritionists (37.8%). The school was the most frequently adapted environment (78%), and had the highest level of structural adaptation (42.7%). CONCLUSIONS: The results of this study suggest that the barriers to access health services and barriers to the physical environment may impact participation and social inclusion.

RESUMO

PURPOSE: To explore the feasibility of an intervention using modified ride-on cars in terms of acceptability and potential changes in goal attainment, mobility, social function, and participation of children with Congenital Zika Syndrome (CZS). MATERIALS AND METHODS: A pre- and post-intervention feasibility study was conducted with children with CZS, levels IV and V of the Gross Motor Function Classification System (GMFCS). The intervention consisted of 12 weeks of training (3 times a week for 40 min per session) and 4 weeks of follow-up. The primary outcomes included adherence, satisfaction, and learning in mobility. Secondary outcomes encompassed goal attainment, mobility, social/cognitive function, and participation. Descriptive statistics were performed. To explore potential individual changes with the intervention, Wilcoxon test was used to analyze Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) data and Young Children's Participation and Environment Measure (YC-PEM)/Participation and Environment Measure for Children and Youth (PEM-CY), along with standard error measurements of the PEDI-CAT domains. RESULTS: Four children participated (median age 4.75 years; two females: three at level V on the GMFCS). Adherence was 75% of the total intervention time, and family members reported being satisfied or very satisfied. Children showed gains in learning the use of the modified ride-on cars and an increase in goal attainment after the intervention. Individual changes were observed in the PEDI-CAT domains (mobility and social/cognitive), but there were no significant changes in participation outcomes. CONCLUSIONS: Children with CZS at GMFCS levels IV and V can learn to use motorized ride-on cars, attainment goals, and experience satisfaction.


Motorized mobility for children with Congenital Zika Syndrome and severe physical and cognitive disabilities is feasible and can encourage future interventions focused on activities and participation.This research contributes to the understanding of the potential changes that motorized mobility can have on goal attainment, satisfaction, and learning.Motorized mobility can be a means to enable children with Congenital Zika Syndrome to have opportunities for participation and guarantee their rights.

RESUMO

OBJECTIVE: To evaluate effects of lidocaine 2% administration into the ovarian pedicle on intraoperative nociception and early postoperative pain in dogs undergoing ovariohysterectomy. STUDY DESIGN: Prospective, randomized, blinded clinical study. ANIMALS: A total of 20 healthy adult female dogs of different breeds. METHODS: Dogs were premedicated with acepromazine (0.02 mg kg-1) and morphine (0.5 mg kg-1) intramuscularly, anesthesia induced with propofol and maintained with isoflurane. Dogs were randomly assigned to be administered 2 mL of saline (group S) or lidocaine 2% (group L) into the mesovarium (1 mL each side). Heart rate (HR) and noninvasive systemic arterial pressure were recorded before surgery (T0), before (T1) and during ligation of the right ovarian pedicle (T2), before (T3) and during ligation of the left ovarian pedicle (T4). Rescue treatment (propofol) was administered if HR or systolic arterial pressure (SAP) increased by 20% compared with the previous time point. Pain, assessed with the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) was recorded before premedication (baseline) and after extubation. Administration of postoperative rescue analgesia was recorded. RESULTS: In group S, HR was higher at T2 than T1 (112 ± 18 versus 89 ± 21 beats minute-1, p = 0.001) There were no significant differences between treatments at any time. SAP was higher at T2 than T1 in group S (110 ± 12 versus 100 ± 10 mmHg, p = 0.031). SAP was higher in group S than group L at T3 (113 ± 12 and 91 ± 10 mmHg, respectively, p = 0.001). No dogs required propofol intraoperatively. All dogs required postoperative rescue analgesia. Compared with baseline, CMPS-SF increased 60 minutes after extubation (group S; p = 0.019, group L; p = 0.043). CONCLUSIONS AND CLINICAL RELEVANCE: Administration of lidocaine 2% into the mesovarium did not reduce intraoperative nociception and did not improve postoperative analgesia.

RESUMO

INTRODUCTION: Congenital Zika syndrome (CZS) is a health condition that has affected the development of thousands of children in Brazil. Because it is a new condition, its understanding is an ongoing process. Therefore, it is important to know the rehabilitation interventions being delivered to improve the functioning of these children. We aimed to describe the practices of physical therapists (PTs) and occupational therapists (OTs) who provide follow-up care for children with CZS in Brazil. METHODS: This cross-sectional study included PTs and OTs who assist children with CZS in Brazil. An online questionnaire was used to verify the participants' personal characteristics and professional work environment, as well as the rehabilitation programs they implemented in Brazil for children with CZS. Data were analyzed using descriptive statistics. RESULTS: A total of 116 professionals (79 PT and 37 OT) who work mainly in public health services (81.9%) participated in the study. Of these, 24.1% plan interventions based on reading scientific articles, 66.4% did not report using the biopsychosocial model, 52.6% do not perform any assessments before starting an intervention, 31.9% use neurodevelopmental treatment, and 22.4% use sensorimotor stimulation interventions. The majority of the interventions are delivered 1 to 2 times a week, lasting up to 1 hour. CONCLUSIONS: Professional training and knowledge translation strategies are needed to implement evidence-based practices and improve the quality of rehabilitation programs for Brazilian children with CZS.

RESUMO

Background: Conventional thoracotomy (CT) often leads to systemic inflammatory response syndrome (SIRS), which induces several clinical complications. CT remains widely used in low-income institutions. Although minimally invasive surgical procedures, such as robotic surgery (RS), have been used to prevent many of the complications inherit from the surgical procedure. Here, we investigated the protective effect of vagus nerve stimulation (VNS) in a pre-clinical model during CT or RS and postoperative period (POP) relative to clinical complications and inflammatory control. The objective was to compare hemodynamic features and cytokine levels in the blood, lung, and bronchoalveolar lavage (BAL) fluids of animals subjected to CT or RS with or without VNS. Methods: Twenty-four minipigs were subjected to 12 animals CT and 12 animals RS, with or without VNS, and accompanied 24 h later by pulmonary lobectomy. Blood samples for evaluating the hemodynamic parameters were collected before the surgical preparation, immediately after the beginning of VNS, and every 4 h until 24 h after the lobectomy. BAL fluid and lung tissue were collected at the end of the experiment. Cytokine levels were evaluated in the blood, BAL fluid, and lung tissues. Results: VNS maintained a more stable heart rate during POP and decreased the incidence of overall cardiac complications while preventing increase in IL-6 levels 12 h after lobectomy, compared to sham animals. No differences were found in cytokine expression in the BAL fluid and lung tissue in any of the studied groups. Conclusions: Taken together, our data suggested that VNS should be considered a non-pharmacological tool in the prevention of the exacerbated inflammatory response responsible for severe clinical complications, especially in more aggressive surgical procedures.

RESUMO

AIMS: To describe the implementation of paediatric rehabilitation telehealth at a physical therapy (PT) unit in Brazil during the COVID-19 pandemic and to describe the perception about this modality by two groups: (1) undergraduate PT students using telehealth during their clinical rotations in this unit and (2) the caregivers of children with disabilities receiving the services. METHODS: Twenty-one PT interns (19 females; 25 ± 2 years of age) and seven caregivers (seven females; 40 ± 6 years of age) of seven children with disabilities (five females; 10 ± 4 years of age; five children diagnosed with cerebral palsy) responded to an online questionnaire about their experience with the telehealth programme. Participant attendance and frequency of objective responses were reported descriptively; open-ended responses were analysed qualitatively and grouped according to broad themes. RESULTS: 71.4% of interns rated telehealth as an excellent or good experience, and 28.6% did not appreciate it. In addition, 28.6% of them thought that telehealth should be part of the mandatory internship. Regarding caregivers, 85.8% judged the telehealth programme as excellent or good. Both interns and caregivers cited pros and cons related to technology, professional resources, communication skills and caregiver-related aspects, among others. CONCLUSIONS: Specific teaching strategies had to be utilised for implementation of telehealth. Despite being a novel modality for interns and caregivers, telehealth was well accepted.

RESUMO

Treatment-resistant depression (TRD) is a debilitating condition that affects millions of individuals worldwide. Deep brain stimulation (DBS) has been widely used with excellent outcomes in neurological disorders such as Parkinson's disease, tremor, and dystonia. More recently, DBS has been proposed as an adjuvant therapy for TRD. To date, the antidepressant efficacy of DBS is still controversial, and its mechanisms of action remain poorly understood. Astrocytes are the most abundant cells in the nervous system. Once believed to be a "supporting" element for neuronal function, astrocytes are now recognized to play a major role in brain homeostasis, neuroinflammation and neuroplasticity. Because of its many roles in complex multi-factorial disorders, including TRD, understanding the effect of DBS on astrocytes is pivotal to improve our knowledge about the antidepressant effects of this therapy. In depression, the number of astrocytes and the expression of astrocytic markers are decreased. One of the potential consequences of this reduced astrocytic function is the development of aberrant glutamatergic neurotransmission, which has been documented in several models of depression-like behavior. Evidence from preclinical work suggests that DBS may directly influence astrocytic activity, modulating the release of gliotransmitters, reducing neuroinflammation, and altering structural tissue organization. Compelling evidence for an involvement of astrocytes in potential mechanisms of DBS derive from studies suggesting that pharmacological lesions or the inhibition of these cells abolishes the antidepressant-like effect of DBS. In this review, we summarize preclinical data suggesting that the modulation of astrocytes may be an important mechanism for the antidepressant-like effects of DBS.

RESUMO

Norepinephrine plays an important role in modulating memory through its beta-adrenergic receptors (Adrß: ß1, ß2 and ß3). Here, we hypothesized that multisensory stimulation would reverse memory impairment caused by the inactivation of Adrß3 (Adrß3KO) with consequent inhibition of sustained glial-mediated inflammation. To test this, 21- and 86-day-old Adrß3KO mice were exposed to an 8-week multisensory stimulation (MS) protocol that comprised gustatory and olfactory stimuli of positive and negative valence; intellectual challenges to reach food; the use of hidden objects; and the presentation of food in ways that prompted foraging, which was followed by analysis of GFAP, Iba-1 and EAAT2 protein expression in the hippocampus (HC) and amygdala (AMY). The MS protocol reduced GFAP and Iba-1 expression in the HC of young mice but not in older mice. While this protocol restored memory impairment when applied to Adrß3KO animals immediately after weaning, it had no effect when applied to adult animals. In fact, we observed that aging worsened the memory of Adrß3KO mice. In the AMY of Adrß3KO older mice, we observed an increase in GFAP and EAAT2 expression when compared to wild-type (WT) mice that MS was unable to reduce. These results suggest that a richer and more diverse environment helps to correct memory impairment when applied immediately after weaning in Adrß3KO animals and indicates that the control of neuroinflammation mediates this response.

RESUMO

Understanding the mechanisms responsible for anxiety disorders is a major challenge. Avoidance behavior is an essential feature of anxiety disorders. The two-way avoidance test is a preclinical model with two distinct subpopulations-the good and poor performers-based on the number of avoidance responses presented during testing. It is believed that the habenula subnuclei could be important for the elaboration of avoidance response with a distinct pattern of activation and neuroinflammation. The present study aimed to shed light on the habenula subnuclei signature in avoidance behavior, evaluating the pattern of neuronal activation using FOS expression and astrocyte density using GFAP immunoreactivity, and comparing control, good and poor performers. Our results showed that good performers had a decrease in FOS immunoreactivity (IR) in the superior part of the medial division of habenula (MHbS) and an increase in the marginal part of the lateral subdivision of lateral habenula (LHbLMg). Poor performers showed an increase in FOS in the basal part of the lateral subdivision of lateral habenula (LHbLB). Considering the astroglial immunoreactivity, the poor performers showed an increase in GFAP-IR in the inferior portion of the medial complex (MHbl), while the good performers showed a decrease in the oval part of the lateral part of the lateral complex (LHbLO) in comparison with the other groups. Taken together, our data suggest that specific subdivisions of the MHb and LHb have different activation patterns and astroglial immunoreactivity in good and poor performers. This study could contribute to understanding the neurobiological mechanisms responsible for anxiety disorders.

RESUMO

Epidural motor cortex stimulation (MCS) is an effective treatment for refractory neuropathic pain; however, some individuals are unresponsive. In this study, we correlated the effectiveness of MCS and refractoriness with the expression of cytokines, neurotrophins, and nociceptive mediators in the dorsal root ganglion (DRG), sciatic nerve, and plasma of rats with sciatic neuropathy. MCS inhibited hyperalgesia and allodynia in two-thirds of the animals (responsive group), and one-third did not respond (refractory group). Chronic constriction injury (CCI) increased IL-1ß in the nerve and DRG, inhibited IL-4, IL-10, and IL-17A in the nerve, decreased ß-endorphin, and enhanced substance P in the plasma, compared to the control. Responsive animals showed decreased NGF and increased IL-6 in the nerve, accompanied by restoration of local IL-10 and IL-17A and systemic ß-endorphin. Refractory animals showed increased TNF-α and decreased IFNγ in the nerve, along with decreased TNF-α and IL-17A in the DRG, maintaining low levels of systemic ß-endorphin. Our findings suggest that the effectiveness of MCS depends on local control of inflammatory and neurotrophic changes, accompanied by recovery of the opioidergic system observed in neuropathic conditions. So, understanding the refractoriness to MCS may guide an improvement in the efficacy of the technique, thus benefiting patients with persistent neuropathic pain.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the cognitive-motor dual-task costs (DTCs) on postural sway of children with typical development (TD) and children with cerebral palsy (CP) during the sit-to-stand movement. METHODS: Twenty children with TD (mean age = 9.35 years) and 17 children with CP (mean age = 8.29 years) randomly performed 3 test conditions: simple motor task, low-complexity cognitive-motor dual-task, and high-complexity cognitive-motor dual-task. The sit-to-stand movement was divided into 3 phases for data analysis: preparation (P1), rising (P2), and stabilization (P3). For each of these phases, the DTCs were calculated by the percentage change in the center of pressure area of sway, velocity of sway, and duration variables between the simple and dual-task conditions. Analysis of variance was applied to test the group, task conditions, and interaction effects. RESULTS: Children with CP had lower DTC than children with TD in area of sway in P1 and P2 variables; anteroposterior velocity of sway in P1, P2, and P3; and duration in P3. Children with TD had higher DTC in the high-complexity cognitive-motor dual-task than in the low complexity one. Children with CP did not show adaptations between the dual-task conditions, showing no differences in DTCs. CONCLUSION: The simultaneous performance of a motor task and a cognitive task seems to affect children with CP and children with TD differently, but the effects depend on the specific demands of each task. These results demonstrate the importance of rehabilitation actions to place demands involving a variety of postural sway strategies. IMPACT: DTCs are different for children with TD and children with CP. Assessment and rehabilitation strategies must take into account the postural sway behavior of these children.

RESUMO

Breast cancer is the second most common diagnosed type of cancer in women. Chronic neuropathic pain after mastectomy occurs frequently and is a serious health problem. In our previous single-center, prospective, randomized controlled clinical study, we demonstrated that the combination of serratus anterior plane block (SAM) and pectoral nerve block type I (PECS I) with general anesthesia reduced acute postoperative pain. The present report describes a prospective follow-up study of this published study to investigate the development of chronic neuropathic pain 12 months after mastectomy by comparing the use of general anesthesia alone and general anesthesia with SAM + PECS I. Additionally, the use of analgesic medication, quality of life, depressive symptoms, and possible correlations between plasma levels of interleukin (IL)-1 beta, IL-6, and IL-10 collected before and 24 h after surgery as predictors of pain and depression were evaluated. The results showed that the use of SAM + PECS I with general anesthesia reduced numbness, hypoesthesia to touch, the incidence of patients with chronic pain in other body regions and depressive symptoms, however, did not significantly reduce the incidence of chronic neuropathic pain after mastectomy. Additionally, there was no difference in the consumption of analgesic medication and quality of life. Furthermore, no correlation was observed between IL-1 beta, IL-6, and IL-10 levels and pain and depression. The combination of general anesthesia with SAM + PECS I reduced the occurrence of specific neuropathic pain descriptors and depressive symptoms. These results could promote the use of SAM + PECS I blocks for the prevention of specific neuropathic pain symptoms after mastectomy.Registration of clinical trial: The Research Ethics Board of the Hospital Sirio-Libanes/Brazil approved the study (CAAE 48721715.0.0000.5461). This study is registered at Registro Brasileiro de Ensaios Clinicos (ReBEC), and ClinicalTrials.gov, Identifier: NCT02647385.

RESUMO

BACKGROUND: Parkinson's disease (PD) is characterized by a progressive loss of nigrostriatal dopaminergic neurons with impaired motor and non-motor symptoms. It has been suggested that motor asymmetry could be caused due to an imbalance in dopamine levels, as visualized by dopamine transporter single emission computed tomography test (DAT-SPECT), which might be related to indirect measures of neurodegeneration, evaluated by the Montreal Cognitive Assessment (MOCA) and α-synuclein levels in the cerebrospinal fluid (CSF). Therefore, this study aimed to understand the correlation between disease laterality, DAT-SPECT, cognition, and α-synuclein levels in PD. METHODS: A total of 28 patients in the moderate-advanced stage of PD were subjected to neurological evaluation, TRODAT-1-SPECT/CT imaging, MOCA, and quantification of the levels of α-synuclein. RESULTS: We found that α-synuclein in the CSF was correlated with global cognition (positive correlation, r2 = 0.3, p = 0.05) and DAT-SPECT concentration in the putamen (positive correlation, r2 = 0.4, p = 0.005), and striatum (positive correlation, r2 = 0.2, p = 0.03), thus working as a neurodegenerative biomarker. No other correlations were found between DAT-SPECT, CSF α-synuclein, and cognition, thus suggesting that they may be lost with disease progression. CONCLUSIONS: Our data highlight the importance of understanding the dysfunction of the dopaminergic system in the basal ganglia and its complex interactions in modulating cognition.
