conferenceObject Inflammatory factors (cytokines and cortisol) across different brain regions in bipolar disorder and their associations with neuropsychiatric symptoms: A post-mortem study(2020) NASCIMENTO, Camila; NUNES, Paula V.; SUEMOTO, Claudia K.; RODRIGUEZ, Roberta D.; LEITE, Renata E. P.; GRINBERG, Lea T.; PASQUALUCCI, Carlos A.; NITRINI, Ricardo; JACOB-FILHO, Wilson; BRENTANI, Helena P.; LAFER, Beny- A review on shared clinical and molecular mechanisms between bipolar disorder and frontotemporal dementia(2019) NASCIMENTO, Camila; NUNES, Paula Villela; RODRIGUEZ, Roberta Diehl; TAKADA, Leonel; SUEMOTO, Claudia Kimie; GRINBERG, Lea Tenenholz; NITRINI, Ricardo; LAFER, BenyMental disorders are highly prevalent and important causes of medical burden worldwide. Co-occurrence of neurological and psychiatric symptoms are observed among mental disorders, representing a challenge for their differential diagnosis. Psychiatrists and neurologists have faced challenges in diagnosing old adults presenting behavioral changes. This is the case for early frontotemporal dementia (FTD) and bipolar disorder. In its initial stages, FTD is characterized by behavioral or language disturbances in the absence of cognitive symptoms. Consequently, patients with the behavioral subtype of FTD (bv-FTD) can be initially misdiagnosed as having a psychiatric disorder, typically major depression disorder (MDD) or bipolar disorder (BD). Bipolar disorder is associated with a higher risk of dementia in older adults and with cognitive impairment, with a subset of patients presents a neuroprogressive pattern during the disease course. No mendelian mutations were identified in BD, whereas three major genetic causes of FTD have been identified. Clinical similarities between BD and bv-FTD raise the question whether common molecular pathways might explain shared clinical symptoms. Here, we reviewed existing data on clinical and molecular similarities between BD and FTD to propose biological pathways that can be further investigated as common or specific markers of BD and FTD.
- Factors associated with brain volume in major depression in older adults without dementia: results from a large autopsy study(2018) NUNES, Paula Villela; SUEMOTO, Claudia Kimie; LEITE, Renata Elaine Paraizo; FERRETTI-REBUSTINI, Renata Eloah de Lucena; PASQUALUCCI, Carlos Augusto; NITRINI, Ricardo; FARFEL, Jose Marcelo; OLIVEIRA, Katia Cristina de; GRINBERG, Lea Tenenholz; COSTA, Nicole Rezende da; NASCIMENTO, Camila Fernandes; SALMASI, Faraz; KIM, Helena Kyunghee; YOUNG, Lionel Trevor; JACOB-FILHO, Wilson; LAFER, BenyObjectiveWe examined brain volume and atrophy in individuals with major depressive disorder (MDD) without dementia that were referred to a large autopsy service. We also examined potential risk factors for brain atrophy, including demographics and clinical variables. MethodsIn this study, 1373 participants (787 male) aged 50years or older who died from natural causes were included. Participants with no reliable informant, with cognitive impairment or dementia, with a medical history of severe chronic disease, or with prolonged agonal state were excluded. Presence of MDD at least once in their lifetime was defined according to the Structured Clinical Interview for DSM. Brain volume was measured immediately after removal from the skull. ResultsMean age at death was 68.611.6, and MDD was present in 185 (14%) individuals. Smaller brain volume was associated with older age (p<0.001), lower education (years; p<0.001), hypertension (p=0.001), diabetes (p=0.006), and female gender (p<0.001). In the multivariate analysis adjusted for sociodemographics and cardiovascular risk factors, smaller brain volume was not associated with major depression (=-0.86, 95% CI=-26.50 to 24.77, p=0.95). ConclusionsIn this large autopsy study of older adults, MDD was not associated with smaller brain volumes. Regardless of the presence of MDD, in this sample of older adults without dementia, we found that smaller brain volumes were associated with risk factors for brain neurodegeneration such as older age, diabetes, hypertension, and lower education.

Methods: We analyzed causes of death in a community-based cohort of participants aged 50 or older, submitted to full-body autopsy and a comprehensive neuropathologic examination of the brain. Individuals with Alzheimer disease (AD), vascular dementia (VaD), mixed dementia (AD+VaD), or dementia with Lewy bodies (DLBs) were compared with individuals with no dementia. Results: In a sample of 920 individuals, 456 had no dementia, 147 had AD, 120 had VaD, 53 had DLB, and 37 had AD+VaD. Pneumonia as the cause of death was more frequent in the AD (P= 0.023), AD+VaD (P= 0.046), and DLB (P= 0.043) groups. In addition, VaD (P= 0.041) and AD+VaD (P= 0.028) groups had a higher frequency of atherosclerosis as detected by full-body autopsy. Conclusion: Our findings highlight the importance of preventive measures regarding atherosclerosis and pneumonia in patients with dementia. Moreover, because of cognitive impairment, these patients may not fully account for symptoms to make early detection and diagnosis possible. These results confirm findings from previous studies that were based on clinical data, with added accuracy provided by neuropathologic diagnosis and full-body autopsy reports.conferenceObject Markers of inflammation and neurodegeneration in bipolar disorder older adults(2021) NASCIMENTO, Camila; NUNES, Paula; SUEMOTO, Claudia K.; RODRIGUEZ, Roberta D.; LEITE, Renata E.

METHODS: In autopsy studies, head circumference was measured with an inelastic tape placed around the skull. Total brain volume was also directly measured. A linear regression was used to determine the association of head circumference with brain volume and clinical variables. Microcephaly was defined as head circumference that were two standard deviations below the mean of significant clinical variables. We further applied an association rule mining to find rules associating microcephaly with several sociodemographic and clinical variables. RESULTS: In our sample of 2,508 adults, the mean head circumference was 55.3 +/- 2.7cm. Head circumference was related to height, cerebral volume, and sex (p < 0.001 for all). Microcephaly was present in 4.7% of the sample (n = 119). Out of 34,355 association rules, we found significant relationships between microcephaly and a clinical dementia rating (CDR) > 0.5 with an informant questionnaire on cognitive decline in the elderly (IQCODE) = 3.4 (confidence: 100% and lift: 5.6), between microcephaly and a CDR > 0.5 with age over 70 years (confidence: 42% and lift: 2.4), and microcephaly and males (confidence: 68.1% and lift: 1.3). CONCLUSION: Head circumference was related to cerebral volume. Due to its low cost and easy use, head circumference can be used as a screening test for microcephaly, adjusting it for gender and height. Microcephaly was associated with dementia at old age.
- Differential levels of inflammatory and neuroendocrine markers in the hippocampus and anterior cingulate cortex of bipolar disorder subjects: A post-mortem study(2020) NASCIMENTO, Camila; NUNES, Paula Villela; SUEMOTO, Claudia Kimie; RODRIGUEZ, Roberta Diehl; LEITE, Renata Elaine Paraizo; GRINBERG, Lea Tenenholz; PASQUALUCCI, Carlos Augusto; NITRINI, Ricardo; JACOB-FILHO, Wilson; BRENTANI, Helena Paula; LAFER, Beny
- beta-amyloid pathology is not associated with depression in a large community sample autopsy study(2021) SALDANHA, Nanci Moreira; SUEMOTO, Claudia Kimie; RODRIGUEZ, Roberta Diehl; LEITE, Renata Elaine Paraizo; NASCIMENTO, Camila; FERRETI-REBUSTINI, Renata; SILVA, Magnolia Moreira da; PASQUALUCCI, Carlos Augusto; NITRINI, Ricardo; JACOB-FILHO, Wilson; LAFER, Beny; GRINBERG, Lea T.; NUNES, Paula VillelaBackground: : Depression has been associated with dementia. This study aimed to verify if 13-amyloid Alzheimer's disease-type burden was associated with lifetime major depressive disorder (MDD) and with current depressive symptoms in a large population-based autopsy study. Methods: : We included 1013 deceased subjects submitted to autopsy (mean age=74.3 +/- 11.6 years, 49% men) in a community sample. 13-amyloid burden was measured in all cases based on the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) criteria for presence and density of neuritic plaques. Lifetime MDD was defined when at least one previous episode according to the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders - DSM (SCID). Depressive symptoms and cognitive impairment were determined using the depression item of the Neuropsychiatric Inventory (D-NPI>0) and the Clinical Dementia Rating scale (CDR>0.5) respectively. Results: : Lifetime MDD, late life depression (LLD) and current depressive symptoms were associated with cognitive impairment (p<0.001). Additionally, neuritic plaques were associated with cognitive impairment (p<0.001). Moderate or frequent neurite plaque density was not associated with MDD, LLD or current depressive symptoms in multiple logistic models adjusted for age, gender, and cognitive impairment. Limitations:: In this cross-sectional study, all neuropsychiatric and cognitive assessment were based on informant-report of deceased participants. Conclusions: : Different clinical depictions of depression were associated with dementia in this large community sample of elderly individuals with multiethnic backgrounds. Notwithstanding, they were unrelated to 13-amyloid pathology in the brain areas studied. The link between depression and dementia might be complex and determined by multiple factors.
