    Cognitive deficits in patients with mild to moderate traumatic brain injury (vol 68, pg 862, 2010)
    (2011) MIOTTO, Eliane Correa; CINALLI, Fernanda Zanetti; SERRAO, Valeria Trunkl; BENUTE, Glaucia Guerra; LUCIA, Mara Cristina Souza; SCAFF, Milberto
    Traumatismo craniencefálico (TCE) é uma das causas mais freqüentes de lesão cerebral. São relatados na literatura déficits cognitivos após TCE moderado-grave relacionados à memória, linguagem, funções executivas, atenção e velocidade de processamento de informações. Estudos em pacientes com TCE leve são escassos embora alterações neuropsicológicas sejam encontradas nestes pacientes. OBJETIVO: Investigar o funcionamento cognitivo de pacientes com TCE leve e moderado através de um protocolo abrangente (PN01) de testes neuropsicológicos. MÉTODO: Foram avaliados 12 pacientes com TCE leve e moderado. RESULTADOS: Foram identificados déficits graves de memória episódica verbal para evocação imediata, tardia e de reconhecimento, de memória episódica visuo-espacial para evocação imediata e tardia, nomeação, fluência verbal nominal e velocidade de processamento de informações. CONCLUSÃO: Os resultados do estudo argumentam a favor da importância de avaliação neuropsicológica abrangente mesmo em casos de TCE leve a fim de se identificar funções comprometidas e preservadas, proporcionando condutas e programas de reabilitação adequados a cada caso.

    Perceptual organization deficits in traumatic brain injury patients
    (2015) COSTA, Thiago L.; ZANINOTTO, Ana Luiza C.; BENUTE, Glaucia G.; LUCIA, Mara C. S. De; PAIVA, Wellingson S.; WAGEMANS, Johan; BOGGIO, Paulo S.
    Traumatic brain injury (TBI) is a prevalent condition and there is limited visual perception research with this population. Here, we investigated perceptual organization changes in a rather homogeneous sample of closed head TBI outpatients with diffuse axonal injury only and no other known comorbidities. Patients had normal or corrected visual acuity. Perceptual organization was measured with the Leuven Perceptual Organization Screening Test (L-POST), a coherent motion task (CM) and the Leuven Embedded Figures Test (L-EFT). These tests were chosen to screen for deficits in different aspects of perceptual organization (L-POST), to evaluate local and global processing (L-EFT) and grouping in a dynamic set of stimuli (CM). TBI patients were significantly impaired compared to controls in all measures for both response time and accuracy, except for CM thresholds and object recognition subtests. The TBI group was similarly affected in all aspects of the L-EFT. TBI was also similarly affected in all perceptual factors of the L-POST. No significant correlations were found between scores and time post-injury, except for CM thresholds (r(s)=-0.74), which might explain the lack of group-level differences. The only score significantly correlated to IQ was L-EFT response time (r(s)=-0.67). These findings demonstrate that perceptual organization is diffusely affected in TBI and this effect has no substantial correlations with IQ. As many of the neuropsychological tests used to measure different cognitive functions involve some level of visual discrimination and perceptual organization demands, these results must be taken into account in the general neuropsychological evaluation of TBI patients.

    Transcranial Direct Current Stimulation for Post-Concussion Syndrome: Study Protocol for a Randomized Crossover Trial
    (2017) AMORIM, Robson Luis Oliveira de; BRUNONI, Andre Russowsky; OLIVEIRA, Mirian Akiko Furutani de; ZANINOTTO, Ana Luiza Costa; NAGUMO, Marcia Mitie; GUIRADO, Vinicius Monteiro de Paula; NEVILLE, Iuri Santana; BENUTE, Glaucia Rosana Guerra; LUCIA, Mara Cristina Souza de; PAIVA, Wellingson Silva; ANDRADE, Almir Ferreira de; TEIXEIRA, Manoel Jacobsen
    Background: Mild traumatic brain injury (MTBI) represents 70-80% of all treated brain injuries. A considerable proportion of MTBI patients experience post-concussion symptoms for a prolonged period after MTBI, and these symptoms are diagnosed as persistent post-concussion syndrome (PPCS). PPCS is defined as a range of physical, cognitive, and emotional symptoms. However, memory and executive dysfunction seems to be one of the most debilitating symptoms. Recently, non-invasive brain stimulation has been studied as a potential treatment method for traumatic brain injury (TBI) patients. Therefore, our primary goal is to verify the effects of transcranial direct current stimulation (tDCS) in patients with PPCS who demonstrate cognitive deficits in long-term episodic memory, working memory, and executive function following MTBI. Methods/design: This is a randomized crossover trial of patients with a history of MTBI with cognitive deficits in memory and executive function. Thirty adult patients will be randomized in a crossover manner to receive three weekly sessions of anodal tDCS (2mA) at left dorsolateral prefrontal cortex, left temporal cortex, and sham stimulation that will be performed at 7-day intervals (washout period). The clinical diagnosis of PPCS will be determined using the Rivermead Post-Concussion Symptoms Questionnaire. Patients who meet the inclusion criteria will be assessed with a neuropsychological evaluation. A new battery of computerized neuropsychological tests will be performed before and immediately after each stimulation. Statistical analysis will be performed to determine trends of cognitive improvement. Discussion: There is paucity of studies regarding the use of tDCS in TBI patients, and although recent results showed controversial data regarding the effects of tDCS in such patients, we will address specifically patients with PPCS and MTBI and no brain abnormalities on CT scan other than subarachnoid hemorrhage. Moreover, due to the missing information on literature regarding the best brain region to be studied, we will evaluate two different regions to find immediate effects of tDCS on memory and executive dysfunction.

    Cognitive impairments in patients with low grade gliomas and high grade gliomas
    (2011) MIOTTO, Eliane C.; SILVA JUNIOR, Aluizio; SILVA, Clemar Correa; CABRERA, Hector Navarro; MACHADO, Melissa A. R.; BENUTE, Glaucia R. G.; LUCIA, Mara C. S.; SCAFF, Milberto; TEIXEIRA, Manoel Jacobsen
    Objective: The relationship between brain tumors and cognitive deficits is well established in the literature. However, studies investigating the cognitive status in low and high-grade gliomas patients are scarce, particularly in patients with average or lower educational level. This study aimed at investigating the cognitive functioning in a sample of patients with low and high-grade gliomas before surgical intervention. Method: The low-grade (G1, n=19) and high-grade glioma (G2, n=8) patients underwent a detailed neuropsychological assessment of memory, executive functions, visuo-perceptive and visuo-spatial abilities, intellectual level and language. Results: There was a significant impairment on verbal and visual episodic memory, executive functions including mental flexibility, nominal and categorical verbal fluency and speed of information processing in G2. G1 showed only specific deficits on verbal and visual memory recall, mental flexibility and processing speed. Conclusion: These findings demonstrated different levels of impairments in the executive and memory domains in patients with low and high grade gliomas.

    The Influence of Depressive Symptoms on Quality of Life after Stroke: A Prospective Study
    (2015) GUAJARDO, Valeri Delgado; TERRONI, Luisa; SOBREIRO, Matildes de Freitas Menezes; ZERBINI, Maria Irene dos Santos; TINONE, Gisela; SCAFF, Milberto; IOSIFESCU, Dan V.; LUCIA, Mara Cristina Souza de; FRAGUAS, Renerio
    Background: Poststroke depressive symptoms have prospectively predicted impairment of health-related quality of life (HRQOL). However, it is not known whether such predictive effect is independent of HRQOL at 1 month after stroke. This study aimed to investigate the impact of depressive symptoms at 1 and 3 months after stroke on the 3-month poststroke HRQOL and to investigate the influence of the HRQOL measured at 1 month after stroke on these relationships. Methods: We prospectively evaluated 67 patients at 1 and 3 months after a first-ever ischemic stroke from 106 eligible patients who have been consecutively admitted to the neurology ward of a teaching hospital. A psychiatrist assessed the presence of depressive symptoms using the 31-item version of the Hamilton Rating Scale for Depression and the HRQOL was assessed with the 36-item Short-Form Health Survey from the Medical Outcomes Study. We used linear regression to measure the impact of depressive symptoms, HRQOL at 1 month, and potential confounders on HRQOL at 3 months. Results: We found an association between depressive symptoms at 1 month and HRQOL at 3 months after the stroke; however, this association was not significant when adjusting for the 1 month poststroke HRQOL. Depressive symptoms at 3 months were associated with HRQOL at 3 months after stroke, independently of the poststroke HRQOL at 1 month and potential confounders. Conclusions: Current depressive symptoms at 3 months are important for HRQOL at 3 months after stroke; however, regarding the prospective prediction, HRQOL at 1 month is the most relevant factor.

    Visuospatial memory improvement in patients with diffuse axonal injury (DAI): a 1-year follow-up study
    (2017) ZANINOTTO, Ana Luiza; VICENTINI, Jessica Elias; SOLLA, Davi Jorge Fontoura; SILVA, Tatiana Tateishi; GUIRADO, Vinicius Monteiro de Paula; FELTRIN, Fabricio; LUCIA, Mara Cristina Souza de; TEIXEIRA, Manoel Jacobsen; PAIVA, Wellingson Silva
    Objective Diffuse axonal injury (DAI) is prevalent in traumatic brain injury (TBI), and is often associated with poor outcomes and cognitive impairment, including memory deficits. Few studies have explored visual memory after TBI and its relationship to executive functioning. Executive functioning is crucial for remembering an object's location, operating devices, driving, and route finding. We compared visual memory performance via the Rey-Osterrieth Complex Figure (ROCF) test 6 and 12 months after DAI. Method In total, 40 patients (mean age 28.7 years; 87.5% male) with moderate-to-severe DAI following a road traffic accident completed the 1-year follow-up. There was a three-phase prospective assessment. In phase 1 (1-3 months after trauma), patients completed the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI). In phases 2 (6 months) and 3 (12 months), they completed the BDI, STAI, and a neuropsychological battery [ROCF copy and recall, digit span forward/backward, Grooved Pegboard test, intelligence quotient (IQ) by Wechsler Adult Intelligence Scale-III (WAIS-III)]. Results There was an improvement in ROCF recall over time (p=0.013), but not ROCF copy (p=0.657).There was no change in executive function (Savage scores) copy (p=0.230) or recall (p=0.155). Age, years of education, severity of the trauma, and IQ did not influence ROCF recall improvement. Conclusion There are time-dependent improvements in visual memory in patients with DAI. Neuroplasticity in the 1st months after trauma provides an opportunity for visuospatial memory learning. The present findings may be useful to formulate management plans for long-term TBI rehabilitation.
