    Cyberbullying and adolescent mental health: systematic review
    (2015) BOTTINO, Sara Mota Borges; BOTTINO, Cássio M. C.; REGINA, Caroline Gomez; CORREIA, Aline Villa Lobo; RIBEIRO, Wagner Silva
    Cyberbullying is a new form of violence that is expressed through electronic media and has given rise to concern for parents, educators and researchers. In this paper, an association between cyberbullying and adolescent mental health will be assessed through a systematic review of two databases: PubMed and Virtual Health Library (BVS). The prevalence of cyberbullying ranged from 6.5% to 35.4%. Previous or current experiences of traditional bullying were associated with victims and perpetrators of cyberbullying. Daily use of three or more hours of Internet, web camera, text messages, posting personal information and harassing others online were associated with cyberbullying. Cybervictims and cyberbullies had more emotional and psychosomatic problems, social difficulties and did not feel safe and cared for in school. Cyberbullying was associated with moderate to severe depressive symptoms, substance use, ideation and suicide attempts. Health professionals should be aware of the violent nature of interactions occurring in the virtual environment and its harm to the mental health of adolescents.

    Validation of a treatment algorithm for major depression in an older Brazilian sample
    (2013) RIBEIZ, Salma R. I.; AVILA, Renata; MARTINS, Camila B.; MOSCOSO, Marco A. A.; STEFFENS, David C.; BOTTINO, Cassio M. C.
    Objective The aim of this study was to investigate the effectiveness of a modified version of the Duke Somatic Algorithm Treatment for Geriatric Depression (STAGED) in a Brazilian sample of older patients with major depression. Besides, we aimed to investigate possible baseline predictive factors for remission in this sample. Methods Sixty-seven depressed individuals were treated according to STAGED over 24 weeks in a prospective cohort design with follow-up. All patients had criteria for major depression and were at least 60 years of age at baseline enrollment. Results During this follow-up, 56 patients could be classified in remitted or not remitted group, 42.85% reached remission, and 57.14% did not reach remission. These results are even better than those found in the original study, probably due to the lower baseline depression severity of our sample. When baseline characteristics were compared between remitted and not remitted groups, scores of Mini Mental State Examination and Cambridge Cognitive Examination (CAMCOG) were the only variables with statistical significant difference (p<0.05) between groups. Logistic regression analysis was carried out to try to predict remission and statistical significance (p<0.05) was found only for baseline MMSE scores. It may mean that patients with mixed cognitive disorders and mood disorders have a worse course of depression. Conclusions This version of STAGED seems to be a useful strategy for treatment of depression in late life. Baseline general cognitive performance might be useful to predict remission of depression in older patients with mild to moderate depression. Further research with different population characteristics should be conducted in order to evaluate its usefulness and feasibility in different settings.

    Amnestic and non-amnestic symptoms of dementia: An international study of Alzheimer's disease in people with Down's syndrome
    (2020) FONSECA, Luciana M.; PADILLA, Concepcion; JONES, Elizabeth; NEALE, Natalie; HADDAD, Glenda G.; MATTAR, Guilherme P.; BARROS, Eriton; CLARE, Isabel C. H.; BUSATTO, Geraldo F.; BOTTINO, Cassio M. C.; HOEXTER, Marcelo Q.; HOLLAND, Anthony J.; ZAMAN, Shahid
    The presence of age-related neuropathology characteristic of Alzheimer's disease (AD) in people with Down syndrome (DS) is well-established. However, the early symptoms of dementia may be atypical and appear related to dysfunction of prefrontal circuitry. Objective To characterize the initial informant reported age-related neuropsychiatric symptoms of dementia in people with DS, and their relationship to AD and frontal lobe function. Methods Non-amnestic informant reported symptoms (disinhibition, apathy, and executive dysfunction) and amnestic symptoms from the CAMDEX-DS informant interview were analyzed in a cross-sectional cohort of 162 participants with DS over 30 years of age, divided into three groups: stable cognition, prodromal dementia, and AD. To investigate age-related symptoms prior to evidence of prodromal dementia we stratified the stable cognition group by age. Results Amnestic and non-amnestic symptoms were present before evidence of informant-reported cognitive decline. In those who received the diagnosis of AD, symptoms tended to be more marked. Memory impairments were more marked in the prodromal dementia than the stable cognition group (OR = 35.07; P < .001), as was executive dysfunction (OR = 7.16; P < .001). Disinhibition was greater in the AD than in the prodromal dementia group (OR = 3.54; P = .04). Apathy was more pronounced in the AD than in the stable cognition group (OR = 34.18; P < .001). Conclusion Premorbid amnestic and non-amnestic symptoms as reported by informants increase with the progression to AD. For the formal diagnosis of AD in DS this progression of symptoms needs to be taken into account. An understanding of the unique clinical presentation of DS in AD should inform treatment options.

    Metamemory and aging: Psychometric properties of the Brazilian version of the Multifactorial Memory Questionnaire for elderly
    (2016) SIMON, Sharon Sanz; ÁVILA, Renata Thomas; VIEIRA, Gilson; BOTTINO, Cássio Machado de Campos
    ABSTRACT Metamemory measures provide subjective memory information and are relevant to investigate memory ability in aging. However, there is a lack of metamemory instruments available in Brazil. Objective: The aim of this study was to examine the psychometric properties of the Brazilian version of the Multifactorial Memory Questionnaire (MMQ), which evaluates different dimensions of subjective memory functioning, such as Feelings, Abilities and Strategies used in everyday life. Methods: The MMQ was translated into Portuguese and administered to 30 Brazilian elderly subjects. The participants underwent cognitive tests, mood scales and metamemory instruments. Results: Analyses revealed good internal consistency (Cronbach's a coefficient ranged from 0.75 to 0.89) and test-retest validity for each MMQ dimensions (positive correlations between two applications ranged from 0.75 to 0.8). Convergent validity evidence for the MMQ was confirmed by significant positive correlations (0.47 to 0.68) with dimensions of the Metamemory in Adulthood scale (MIA) (i.e., the Ability, Control, Self-efficacy and Strategy dimensions). Discriminant validity revealed no associations between the MMQ and cognitive performance, suggesting a weak metamemory-objective memory correspondence. Moreover, there was a negative correlation between MMQ-Ability subscale scores and mood symptoms (-0.63 for anxious symptoms, and -0.54 for depressive symptoms); and the Brazilian MMQ was comparable with MMQ translations to other languages. Conclusion: The Brazilian MMQ exhibits good psychometric properties and appears promising for clinical and research purposes. Additional studies are needed to further examine the psychometric properties of the Brazilian MMQ in a larger sample.

    Neuropsychiatric Symptoms, Caregiver Burden and Distress in Behavioral-Variant Frontotemporal Dementia and Alzheimer's Disease
    (2015) LIMA-SILVA, Thais Bento; BAHIA, Valeria Santoro; CARVALHO, Viviane Amaral; GUIMARAES, Henrique Cerqueira; CARAMELLI, Paulo; BALTHAZAR, Marcio Luiz; DAMASCENO, Benito; BOTTINO, Cassio Machado; BRUCKI, Sonia Maria; NITRINI, Ricardo; YASSUDA, Monica Sanches
    Background/Aims: We aimed to compare caregiver burden and distress in behavioral-variant frontotemporal dementia (bvFTD) and Alzheimer's disease (AD) and to investigate which factors contribute to caregivers' burden and distress. Methods: Fifty patients and their care-givers were invited to participate. Among the patients, 20 had a diagnosis of bvFTD and 30 had AD. Caregivers and patients were statistically equivalent for age, sex, education and dementia severity according to Clinical Dementia Rating. The protocol included the Short Zarit Burden Inventory, the Neuropsychiatric Inventory (NPI), Disability Assessment for Dementia (DAD), the Cornell Scale for Depression in Dementia (CSDD), Addenbrooke's Cognitive Examination-Revised, the Executive Interview with 25 Items, Direct Assessment of Functional Status and the Geriatric Anxiety Inventory (GAI). Results: In the NPI, caregivers of bvFTD patients reported a higher presence and severity of neuropsychiatric symptoms and caregiver distress compared to caregivers of AD patients. There was no significant difference in the perceived burden. In bvFTD, DAD and GAI scores were significantly correlated with burden, whereas in AD, burden was correlated with CSDD and NPI scores. Psychiatric symptoms were associated with distress in both groups. Conclusions: Caregivers of bvFTD patients experienced higher levels of distress than caregivers of AD patients. Patients' functional limitations were associated with burden of caregivers of bvFTD patients, whereas neuropsychiatric symptoms were associated with caregiver strain in both groups. (C) 2015 S.

    Analysis of the posterior cingulate cortex with [ 18 F]FDG-PET and Naa/mI in mild cognitive impairment and Alzheimer's disease: Correlations and differences between the two methods
    (2015) COUTINHO, Artur M.N.; PORTO, Fábio H.G.; ZAMPIERI, Poliana F.; OTADUY, Maria C.; PERROCO, Tíbor R.; OLIVEIRA, Maira O.; NUNES, Rafael F.; PINHEIRO, Toulouse Leusin; BOTTINO, Cassio M.C.; LEITE, Claudia C.; BUCHPIGUEL, Carlos A.
    ABSTRACT Reduction of regional brain glucose metabolism (rBGM) measured by [18F]FDG-PET in the posterior cingulate cortex (PCC) has been associated with a higher conversion rate from mild cognitive impairment (MCI) to Alzheimer's disease (AD). Magnetic Resonance Spectroscopy (MRS) is a potential biomarker that has disclosed Naa/mI reductions within the PCC in both MCI and AD. Studies investigating the relationships between the two modalities are scarce. OBJECTIVE To evaluate differences and possible correlations between the findings of rBGM and NAA/mI in the PCC of individuals with AD, MCI and of cognitively normal volunteers. METHODS Patients diagnosed with AD (N=32) or MCI (N=27) and cognitively normal older adults (CG, N=28), were submitted to [18F]FDG-PET and MRS to analyze the PCC. The two methods were compared and possible correlations between the modalities were investigated. RESULTS The AD group exhibited rBGM reduction in the PCC when compared to the CG but not in the MCI group. MRS revealed lower NAA/mI values in the AD group compared to the CG but not in the MCI group. A positive correlation between rBGM and NAA/mI in the PCC was found. NAA/mI reduction in the PCC differentiated AD patients from control subjects with an area under the ROC curve of 0.70, while [18F]FDG-PET yielded a value of 0.93. CONCLUSION rBGM and Naa/mI in the PCC were positively correlated in patients with MCI and AD. [18F]FDG-PET had greater accuracy than MRS for discriminating AD patients from controls.

    Clinical and sociodemographic factors in a sample of older subjects experiencing depressive symptoms
    (2012) BARCELOS-FERREIRA, Ricardo; LOPES, Marcos A.; NAKANO, Eduardo Yoshio; STEFFENS, David C.; BOTTINO, Cassio M. C.
    Objectives This study aims to determine the frequency of clinically significant depressive symptoms (CSDS) in a community sample of older Brazilians and to examine their relationship with sociodemographic factors, cognitive and functional impairment (CFI), and medical illness. Methods A total of 1145 subjects aged 60?years or older living in the City of Ribeirao Preto, State of Sao Paulo, Brazil, were interviewed. The following instruments were used: a 10-item scale for screening of depressive symptoms in older people, the mini mental state examination, the Fuld Object Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, the Bayer Activities of Daily Living Scale, and a sociodemographic and clinical questionnaire. Results The frequency of CSDS was 15.7%. Logistic regression analysis indicated that being previously depressed, having CFI, having lower level of education, using psychotropics, and not engaging in physical exercise were related to CSDS. On the other hand, being a woman, older, medically ill, employed, or married was not associated with CSDS. Conclusions Consistent with previous reports, lower education, lack of physical activity, and CFI were significantly associated with higher frequencies of CSDS. Further investigations are necessary to clarify the occurrence of depression and possible modifiable factors in developing countries such as Brazil.
