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.
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.

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.
