RESUMEN
OBJECTIVES: Fibromyalgia (FM) is a chronic condition characterised by widespread pain, and cognitive difficulties represent one of the most common symptoms of FM. However, subjective cognitive complaints (SCC) may not necessarily indicate significant abnormalities in objective cognitive performances, and there is limited research investigating the relationship between these two aspects. This study thus aims to analyse the differences between SCC and objective cognitive performance in FM patients and to explore their associations. METHODS: A total of 32 FM female patients (age: 50.91±7.06; years since diagnosis: 4.34±4.53) recruited in this study underwent a comprehensive assessment covering four domains: pain, depression, trait anxiety, SCC, and objective cognitive functions (memory, executive function, and information processing speed). RESULTS: Eighty-seven percent of patients experienced significant negative impacts from pain; meanwhile, 91% and 62% showed marked tendencies towards trait anxiety and depression, respectively. Additionally, 56% of patients reported significantly higher levels of SCC. However, less than one-third of patients demonstrated impairments in various cognitive functions. SCC significantly correlated with pain intensity, depression, information processing speed, and trait anxiety, with pain intensity being a significant predictor (R2=.30). Furthermore, patients with significant SCC exhibited more abnormalities in pain, information processing speed, and trait anxiety compared to those without significant SCC. CONCLUSIONS: SCC may not necessarily correlate with objective cognitive impairments and might be specifically linked to defective information processing speed. It thus merits that clinical assessments for FM patients should incorporate measurements of information processing speed to gain a comprehensive understanding of SCC in FM patients.

To determine whether heart rate variability biofeedback (HRV-BF) training, compared to a psychoeducation control condition can strengthen the integration of the central and autonomic nervous systems as measured by neuropsychological measures in patients with mild traumatic brain injury (mTBI). Participants were recruited from two university hospitals in Taipei, Taiwan. A total of 49 participants with mTBI were recruited for this study. Forty-one participants completed the study, 21 in the psychoeducation group and 20 in the HRV-BF group. Randomized controlled study. The Taiwanese Frontal Assessment Battery, the Semantic Association of Verbal Fluency Test, the Taiwanese version of the Word Sequence Learning Test, the Paced Auditory Serial Addition Test-Revised, and the Trail Making Test were used as performance-based neuropsychological functioning measures. The Checklist of Post-concussion Symptoms, the Taiwanese version of the Dysexecutive Questionnaire, the Beck Anxiety Inventory, the Beck Depression Inventory, and the National Taiwan University Irritability Scale were used as self-report neuropsychological functioning measures. Furthermore, heart rate variability pre- vs. post-training was used to measure autonomic nervous system functioning. Executive, information processing, verbal memory, emotional neuropsychological functioning, and heart rate variability (HRV) were improved significantly in the HRV-BF group at the posttest whereas the psychoeducation group showed no change. HRV biofeedback is a feasible technique following mild TBI that can improve neuropsychological and autonomic nervous system functioning. HRV-BF may be clinically feasible for the rehabilitation of patients with mTBI.

PRIMARY OBJECTIVE: Headache, both before and after injury, has been associated with worse outcome following mild traumatic brain injury (MTBI). This study examined whether three MTBI patient groups - no headache (reported no pre-/post-injury headache), pre-injury headache (reported pre-injury headache, nearly all of whom also reported post-injury headache), and post-traumatic headache only (denied pre-injury headache and reported post-injury headache) - differed in acute-to-subacute outcomes. RESEARCH DESIGN: Cross-sectional observational study. METHODS AND PROCEDURES: Patients within 21 days of a MTBI (n = 291) completed neuropsychological tests and questionnaires evaluating depression, anxiety, and post-concussion symptoms. MAIN OUTCOMES AND RESULTS: Neuropsychological test performances did not differ between headache groups. Participants with pre-injury headache and participants with post-traumatic headache only reported greater change in self-reported physical and cognitive symptoms than participants with no headache. Participants with pre-injury headache reported worse post-injury anxiety symptoms than participants with post-traumatic headache only. CONCLUSIONS: The pre-injury headache and post-traumatic headache only groups did not meaningfully differ in outcome within 21 days of MTBI, but they had worse physical and cognitive symptoms than participants with no headache. Future research should assess whether differences in outcome emerge further from injury and whether specific headache subtypes are differentially associated with outcome.

PURPOSE: The relationships between postoperative functional improvement in various cognitive domains and regional hemodynamic change have not been sufficiently studied in childhood moyamoya disease (MMD). The present study aimed to examine the cognitive benefit of indirect revascularization, the underlying biological mechanism, and factors affecting surgical outcome in childhood MMD. METHODS: Twenty-three patients with MMD aged under 20 years received neuropsychological examinations before and after indirect revascularization surgery, evaluating intellectual function, verbal and visual memory, and executive function. Among them, 13 patients had magnetic resonance perfusion (MRP) studies, in which regional cerebral perfusion was rated. RESULTS: Postoperative improvement was observed in verbal memory performances (p = 0.02-0.03) and in cerebral perfusion at all 26 cerebral hemispheres (p = 0.003-0.005), especially in the middle cerebral artery (MCA) territories (p = 0.001-0.003). Hemodynamic improvement in the left MCA territories was significantly correlated with improvement of both verbal new learning (p = 0.01) and intellectual function (p = 0.004). Postoperative cognitive improvement of immediate recall and verbal intellectual function was associated with female sex (r = - 0.42) and symptom duration (p = - 0.03), respectively. Hemodynamic improvement in the MCA territories was related to longer follow-up intervals (p = 0.02). CONCLUSION: The findings revealed that the selective postoperative cognitive improvement was associated with increased regional perfusion in the MCA territories, and indicate the importance of early intervention and the potential of indirect revascularization regarding long-term outcome.

PRIMARY OBJECTIVE: Although 'return to work' (RTW) has been always emphasized for patients with mild traumatic brain injury (MTBI), methodological drawbacks weakened its representativeness. This study thus aims to evaluate the 'work quality' (WQ) which originated from 'working status' and 'working stability' simultaneously, and to further explore the associations among post-concussion symptoms (PCS), neuropsychological functions and WQ. METHODS AND PROCEDURES: A total of 179 participants, which included 132 patients with MTBI and 47 healthy participants, were prospectively recruited. The work quality index (WQI) was developed to evaluate WQ. All patients were evaluated for their PCS, neuropsychological functions and WQ at two weeks post-injury (T1), while PCS and WQ were recorded by one month post-injury (T2). RESULTS: More than half of the patients were not able to retain their pre-injury jobs at T1, while 26% of the patients still failed to regain previous works at T2. Interestingly, WQ was significantly associated with educational levels and physical PCS, such as headache and dizziness. CONCLUSIONS: Simultaneously considering working status and stability to reveal the quality of RTW is merited. A higher educational level might be a protective factor for successful RTW, and ameliorating physical symptoms is also necessary to get favourable WQ by one month after MTBI.

BACKGROUND: Prominent executive dysfunction can differentiate vascular dementia from Alzheimer disease (AD). However, it is unclear whether the Frontal Assessment Battery (FAB) screening tool can differentiate subcortical ischemic vascular disease (SIVD) from AD at the pre-dementia stage. In addition, the neural correlates of FAB performance have yet to be clarified. METHODS: Patients with mild cognitive impairment (MCI) due to SIVD (MCI-V), MCI due to AD (MCI-A), and demographically matched controls completed the Mini-Mental State Examination, Taiwanese FAB (TFAB), Category Fluency, and Chinese Version of the Verbal Learning Test, and underwent magnetic resonance imaging. White matter hyperintensities were rated according to the Scheltens scale. RESULTS: TFAB total scale and its Orthographical Fluency subtest were the only measures that could differentiate MCI-V from MCI-A. Discriminative analysis showed that Orthographical Fluency scores successfully identified 73.2% of the cases with MCI-V, with 85.0% sensitivity. Orthographical Fluency scores were specifically associated with lesion load within frontal periventricular, frontal deep white matter, and basal ganglia regions. CONCLUSION: The TFAB, and especially its 1-min Orthographical Fluency subtest, is a useful screening procedure to differentiate MCI due to SIVD from MCI due to AD. The discriminative ability is probably due to frontosubcortical white matter pathologies disproportionately involved in the two disease entities.

BACKGROUND/PURPOSE: Midazolam is a widely used sedative agent during colonoscopy, with cognitive toxicity. However, the potential cognitive hazard of midazolam-based light sedation has not been sufficiently examined. We aimed to examine the cognitive safety and vulnerability profile under midazolam light sedation, with a particular focus on individual variations. METHODS: We conducted a prospective case-controlled study in an academic hospital. In total, 30 patients undergoing sedative colonoscopy as part of a health check-up were recruited. Neuropsychological testing on the full cognitive spectrum was evaluated at 15 minutes and 120 minutes after low-dose midazolam administration. The modified reliable change index (RCI) was used for intrapersonal comparisons and controlling for practice effects. RESULTS: Midazolam affected psychomotor speed (48%), memory (40%), learning (32%), working memory (17%), and sustained attention (11%), while sparing orientation and the fluency aspect of executive function at the acute stage. Residual memory (10%) and learning (10%) impairments at 2 hours after administration were evidenced in some patients. The three object recall and digit symbol coding tests can serve as useful screening tools. CONCLUSION: Midazolam-based light sedation induced selective cognitive impairments and prolonged cognitive impairments occurred in patients with advanced age. A longer observation time and further screening were recommended for patients due to their at risk state.

PURPOSE: Moyamoya disease is characterized by progressive narrowing of bilateral internal carotid arteries. Neuropsychological impairments are suspected due to frequent involvement of the frontotemporal areas. The present study thus aimed to investigate the pattern of neuropsychological function in children diagnosed with moyamoya disease. METHODS: Thirteen children with moyamoya disease of the transient ischemic attack type received standardized neuropsychological tests that evaluate general intellectual function, verbal comprehension, perceptual organization, working memory, processing speed, episodic memory, category fluency and visuospatial function. Related clinical factors were also analyzed. RESULTS: The results showed single-domain cognitive impairment in around 15 % of patients and multiple-domain cognitive impairments in 23 % of patients. Selective impairments of episodic memory and processing speed were especially noted in those with younger age of onset and prolonged symptom duration. CONCLUSIONS: Neuropsychological impairments are not infrequent in children with moyamoya disease despite normal general intellectual functioning. The pattern of cognitive dysfunction is often associated with lesions in frontotemporal areas. Early detection and intervention shall be considered regarding cognitive outcome in pediatric group.

PRIMARY OBJECTIVES: To evaluate irritability in patients with mild traumatic brain injury (mTBI) and moderate-to-severe traumatic brain injury (msTBI), respectively. RESEARCH DESIGN: A prospective study was conducted at a level I trauma centre. METHODS AND PROCEDURES: A total of 160 participants, which included 80 healthy subjects and 80 patients with TBI, were recruited. Irritability was assessed by the National Taiwan University Irritability Scale and other cognitive functions, which included memory, executive function and information processing, were also evaluated. MAIN OUTCOMES AND RESULTS: The results showed post-injury self-reported irritability in patients with mTBI and family-reported irritability in patients with msTBI were significantly higher than irritability reported by healthy participants. Irritability was significantly associated with information processing ability in patients with mTBI, but it was not associated with any cognitive functions in patients with msTBI. CONCLUSIONS: Irritability was found to be prominent after TBI. Divergent causes of irritability seemed apparent in patients with mTBI and msTBI. Irritability after mTBI appeared might be related to the cognitive functions disrupted after the injury, whereas irritability after msTBI appeared to result directly from the brain lesions involved.

Amorphous-Ge (α-Ge) or free-standing nanoparticles (NPs) synthesized via hydrogen-free plasma-enhanced chemical vapor deposition (PECVD) were applied as transmissive or reflective saturable absorbers, respectively, for starting up passively mode-locked erbium-doped fiber lasers (EDFLs). Under a threshold pumping power of 41 mW for mode-locking the EDFL, the transmissive α-Ge film could serve as a saturable absorber with a modulation depth of 52-58%, self-starting EDFL pulsation with a pulsewidth of approximately 700 fs. Under a high power of 155 mW, the pulsewidth of the EDFL mode-locked by the 15 s-grown α-Ge was suppressed to 290 fs, with a corresponding spectral linewidth of 8.95 nm due to the soliton compression induced by intra-cavity self-phase modulation. The Ge-NP-on-Au (Ge-NP/Au) films could also serve as a reflective-type saturable absorber to passively mode-lock the EDFL with a broadened pulsewidth of 3.7-3.9 ps under a high-gain operation with 250 mW pumping power. The reflection-type Ge-NP/Au film was an imperfect mode-locker, owing to their strong surface-scattered deflection in the near-infrared wavelength region. From the abovementioned results, both ultra-thin α-Ge film and free-standing Ge NP exhibit potential as transmissive and reflective saturable absorbers, respectively, for ultrafast fiber lasers.
RESUMEN
BACKGROUND: Optimized conservative treatment of rib fractures has long been practiced, but surgical fixation has not been promising until recently. We aimed to examine and analyze immediate postoperative outcomes and 6-month quality of life after injury in patients with moderately severe traumatic rib fractures. METHODS: We conducted a prospective cohort study between July 2017 and June 2019 at the National Taiwan University Hospital. Seventy-two patients with moderately severe thoracic trauma were enrolled; 38 received conservative treatment and 34 underwent surgical fixation. Quality of life was measured using the 36-item Short Form Survey at; the first 3 days of hospitalization; before discharge; and at 1-, 2-, and 6-month follow-ups (visits 1-5). Baseline characteristics and clinical outcomes were recorded, and linear regression analysis was conducted using the generalized estimating equation. RESULTS: Among patients with moderately severe thoracic injury (chest Abbreviated Injury Scale score≥ 2), the operative group had more severe injuries and longer intensive care unit and in-hospital stays. However, they had a comparable quality of life 6 months after injury and higher physical component scores in the early postoperative period. Linear regression analysis obtained an equation with several factors positively affecting prediction of the mean physical component score, such as body mass index ≤25, age ≤36 years, fewer ribs requiring fixation, and diabetes mellitus. Mental component score did not show an upward trend, but the Work Quality Index largely determined the predicted mean value of the mental component score. CONCLUSION: Surgical rib fixations hasten recovery in patients with severe thoracic injury (chest Abbreviated Injury Scale ≥3) to achieve 6-month quality of life comparable to patients injured less severely (chest Abbreviated Injury Scale ≥2). The ability to resume previous work positively influenced the mental component score; thus, surgical intervention should also aim to help patients regain their social function.

Return to work (RTW) has always been a determinant functional outcome in patients with mild traumatic brain injury (MTBI). However, the quality of long-term RTW was still unclear. This study thus aims to examine long-term work quality and to reveal its associating factors. A total of 110 patients with MTBI was prospectively recruited. Post-concussion symptoms (PCS) and RTW were evaluated by the Checklist of Post-Concussion Symptoms (CPCS) and Work Quality Index (WQI) respectively at one-week and long-term evaluation (M = 2.90 years, SD = 1.29) post-injury. Only 16% of patients can successfully RTW at one-week post-injury, while 69% of patients have retained their jobs at long-term evaluations. Importantly, 12% of patients had to work under the adverse impacts of PCS at one-week after MTBI, and long-term WQI was significantly associated with PCS at one-week post-injury. Almost 1/3 of patients still had unfavorable long-term work quality even though they could return to work. Thus, a careful evaluation of the early PCS endorsement and work quality for patients with MTBI is merited.
RESUMEN
Purpose: People with pain problems are highly vulnerable to cultural disparities, and it is imperative to reduce these inequalities. This cross-sectional study aimed to develop a culturally sensitive Chronic Pain Cognition Scale (CPCS) for Chinese-/Chinese dialect-speaking populations and investigate its psychometric properties. Patients and Methods: Adult patients with chronic low back pain or chronic neck pain who visited pain clinics at a medical center in northern Taiwan were enrolled. Participants completed the demographic, intensity of pain, and two other related sensations, "Sng ()" and "Ma ()", often reported in Chinese-speaking populations, CPCS, Chronic Pain Acceptance Questionnaire-8, and Pain Self-Efficacy Questionnaire. Results: 200 patients were included. Patients' mean age was 64.84 ± 14.33, 126 (63.0%) were female, and 83 (41.5%) had 13+ years of education. The average duration of pain was 77.25 ± 97.46 months, the intensity of pain was 6.04 ± 2.50, Ma was 3.43 ± 3.24, and Sng was 4.54 ± 3.14. The CPCS comprised four factors: pain impact (how pain impact one's life), losing face (how one being disrespected due to pain), helplessness, and avoidance, with good structural validity and adequate reliability (Cronbach α, 0.60-0.81) and satisfactory criterion-related validity. Moreover, losing face, an essential concept in Chinese relationalism, was significantly related to pain, Sng, and Ma (r = 0.19, 0.15 and 0.16), but not to pain acceptance or self-efficacy, indicating a culturally specific element in pain measurement. Conclusion: The CPCS has good psychometric properties and is suitable for evaluating chronic pain in the clinical setting, and might be generalizable to other Chinese-/Chinese dialect-speaking populations.
RESUMEN
PRIMARY OBJECTIVES: To evaluate irritability following traumatic brain injury. RESEARCH DESIGN: A prospective study was conducted at a level I trauma centre. METHODS AND PROCEDURES: One hundred and forty-four participants, which included 80 healthy subjects and 64 patients suffering from TBI, were recruited. Irritability was assessed by the National Taiwan University Irritability Scale (NTUIS) from patients themselves and their families. MAIN OUTCOMES AND RESULTS: the results showed 14.8% of patients and 29.4% of their families reported patients' problems of irritability. Meanwhile, both self-reported and family-reported irritability post-injury were significantly higher than those reported by the healthy subjects. When evaluating two sub-components of irritability, respectively, both family- and self-reported post-injury annoyance were significantly higher than the pre-injury one, while the self-reported post-injury verbal aggression was not. CONCLUSIONS: TBI patients have remarkable problems of irritability after injuries. Specifically, the results showed that annoyance might be the main characteristic of irritability in TBI patients and patients themselves might be unaware of their verbal aggression post-injury. Hence, it is merited to pay more attention to the annoyance of the patients with TBI and to the reports from significant caregivers when evaluating TBI patients' irritability in clinical settings.

Researchers have examined differences on ImPACT® in baseline symptom reporting and neurocognitive performances based on the language of administration and racial/ethnic identity. This is the first study to examine differences between student-athletes tested in Mandarin versus English on ImPACT® during preseason baseline assessments conducted in high schools in the United States. Participants included 252 adolescent student-athletes who completed ImPACT® testing in the state of Maine in Mandarin and 252 participants who completed testing in English, matched on age, gender, and health and academic history. Participants were compared on neurocognitive composite scores and symptom ratings. Boys tested in Mandarin, but not girls, had modestly better neurocognitive performance on one of four composite scores (i.e., Visual Motor Speed, p < .001, d = .45). Although language groups did not differ in total symptom severity, boys tested in Mandarin endorsed multiple physical symptoms at higher rates than boys tested in English. These results suggest that the current ImPACT® neurocognitive normative data are reasonably appropriate for use with adolescents evaluated in Mandarin. There were some differences in the reporting of physical symptoms, with greater rates of symptom endorsement by boys tested in Mandarin than boys tested in English; but overall symptom severity ratings were comparable between the language groups.

Infiltrative non-GBM gliomas are common primary intracranial malignancies, and postoperative adjuvant radiotherapy is recommended for most adult patients diagnosed with this disease to enhance local control and prolong intracranial progression-free survival (PFS). However, RT-related neurocognitive function (NCF) consequences should not be ignored. Early neurocognitive decline principally includes episodic memory, associated significantly with functions of the hippocampus. This prospective study aims to investigate the impact of adjuvant brain irradiation on neurocognitive performances and relevant oncological outcomes.Twenty-five patients with intracranial infiltrative non-GBM gliomas were enrolled when postoperative adjuvant RT was recommended. All recruited patients should receive baseline brain magnetic resonance imaging, and neuropsychological assessments before and 4 months after the RT course. A battery of neuropsychological measures, mainly including executive functions, memory, psychomotor speed and visuoconstructive ability, was used to evaluate NCFs of interest.Analyzing the delta values between post-irradiation and baseline NCF scores, we observed a robust trend reflecting cognitive stabilization rather than deterioration in almost all NCF. Both verbal and visual memory functions exhibited significant differences in the corresponding scaled scores (Z = -2.722, p = .006, regarding verbal memory; Z = -2.246, p = .025, concerning non-verbal memory). Moreover, patients' neuropsychological performances associated with psychomotor speed and executive functions also disclosed a tendency toward stabilization/improvement.This prospective study demonstrated that patients with infiltrative non-GBM exhibited a marked tendency toward neurocognitive stabilization after receiving postoperative adjuvant RT.

RESUMEN
Conventional treatment for treating primary central nervous system lymphoma (PCNSL) has consisted of either whole-brain radiotherapy (WBRT) or methotrexate (MTX)-based combined modality therapy. However, delayed cognitive sequelae have emerged as a significant debilitating complication in PCNSL patients. A prospective observational case-series study with prospective assessments of neurocognitive functions (NCFs), neuroimaging, and activities of daily living in newly-diagnosed PCNSL patients was undertaken. A battery of neuropsychological measures, used to evaluate NCFs, is composed of ten standardized NCF tests, representing four domains sensitive to disease and treatment effects (executive function, attention, verbal memory, psychomotor speed), and activities of daily living. A total of 15 patients with newly-diagnosed PCNSL were consecutively enrolled in this study. Comparing the NCF scores between the baseline (before WBRT) and post-treatment (after combined chemoradiation therapy) intervals (Mean = 122.33 days, SD = 34.49, range = 77-196), neurobehavioral outcomes consistently remained improving or stable in almost each domain of NCF. Specifically, the scores on Paced Auditory Serial Addition Test-Revised (PASAT-R) were significantly improved between the baseline and post-chemoradiation assessment. Under the multidisciplinary treatment guidelines for treating patients with newly-diagnosed PCNSL, multi-domain NCF become stabilized and even improved after the course of conformal WBRT combined with or without MTX-based chemotherapy.

BACKGROUND: This study aimed to identify early radiologic signs that are predictive of hemorrhage progression and clinical deterioration in patients with traumatic cerebral contusion. We hypothesized that contrast extravasation (CE) and blood-brain barrier disruption might be associated with hemorrhage progression, brain edema, and clinical deterioration in these patients. METHODS: Twenty-two patients with traumatic cerebral contusion (diagnosed on initial noncontrast head computed tomography [CT]) who initially did not require surgical intervention were enrolled in this study. Contrast-enhanced and perfusion CT scans were performed within 6 hours of injury, and follow-up noncontrast CT scans were performed at 24 hours and 72 hours. RESULTS: In each noncontrast CT scan, the volumes of the contusion hemorrhage and edema were calculated using computerized planimetric techniques. The initial Glasgow Coma Scale, hemorrhage progression, clinical deterioration, and the need for subsequent surgery were recorded. The early radiologic findings were compared with these parameters and functional outcome at 6 months to identify predictive radiologic signs. CE was present in 9 of 22 patients (41%) and was highly associated with hemorrhage progression (p < 0.05), clinical deterioration (p < 0.01), and need for subsequent surgery (p < 0.01). In addition, patients with CE had a greater volume of edema at 24 hours (p < 0.01) and 72 hours (p < 0.01) than those who did not have CE. However, CE was not found to be associated with poor outcome. CONCLUSIONS: Early parenchymal CE is associated with hemorrhage progression, cerebral edema, clinical deterioration, and need for subsequent surgery. These patients should be monitored closely, and early surgery may be needed if deterioration occurs. Further elucidation of the pathophysiology is needed to formulate effective treatment for these high-risk patients.

BACKGROUND: Promisingly, the technique of hippocampus sparing during WBRT (HS-WBRT) might preserve NCFs. In this research, we examined oncological outcomes, with emphasis on neurologic/non-neurologic causes of death, CNS progression, and leptomeningeal disease (LMD) recurrence in cancer patients who underwent HS-WBRT. METHODS: One hundred and fourteen cancer patients with newly diagnosed brain oligometastases underwent HS-WBRT were consecutively enrolled. The cumulative incidence of cancer-specific deaths (neurologic or non-neurologic), LMD recurrence, and the composite endpoint of CNS progression (CNS-CE) as the first event were computed with a competing-risks approach to characterize the oncological outcomes after HS-WBRT. RESULTS: Patients with intact brain metastases had a significantly increased likelihood of dying from non-neurologic causes of death associated with early manifestation of progressive systemic disease (hazard ratio for non-neurologic death, 1.78; 95% CI, 1.08-2.95; p = 0.025; competing-risks Fine-Gray regression), which reciprocally rendered them unlikely to encounter LMD recurrence or any pattern of CNS progression (HR for CNS-CE as the first event, 0.13; 95% CI, 0.02-0.97; p = 0.047; competing-risks Fine-Gray regression). By contrast, patients with resection cavities post-craniotomy had reciprocally increased likelihood of CNS progression which might be associated with neurologic death eventually. CONCLUSIONS: Patterns of oncological endpoints including neurologic/non-neurologic death and cumulative incidence of CNS progression manifesting as LMD recurrence are clearly clarified and contrasted between patients with intact BMs and those with resection cavities, indicating they are clinically distinct subgroups.

RESUMEN
OBJECTIVE: Postconcussion symptoms (PCS) are commonly reported by patients with mild traumatic brain injury (MTBI). Although PCS significantly recovered by 3-month postinjury, a number of patients still experienced persistent PCS for >1 year. As few researchers investigated long-term PCS endorsement, the present study thus aims to show the latent structure of long-term PCS and further uncover its associating factors. METHODS: In total, 110 patients with MTBI and 32 healthy participants were prospectively enrolled. PCS was evaluated at 2 weeks and long-term evaluations (mean = 2.90 years) after MTBI. In addition, cognitive functions, which include memory, executive function, and information processing, and emotional disturbances, which include depression, anxiety, and irritability, were also examined at 2-week postinjury. RESULTS: Patients reported significantly more PCS at 2-week postinjury than healthy participants did, but PCS significantly improved at long-term evaluations when comparing with PCS at acute stage after MTBI. Both of PCS at 2 weeks and long-term evaluations can be further subdivided into subgroups based on the severity of PCS, in which specific PCS (e.g., fatigue, loss of energy, insomnia, slowness of information processing, irritability, and blurred vision) can be well differentiated among subgroups at long-term evaluations. CONCLUSIONS: This study directly showed the characteristics of long-term PCS and associating factors. It further evidenced that specific physical, cognitive, and emotional symptoms might be determinant to identify the subgroups of patients with long-term PCS endorsement.
