- Functioning in older adults with bipolar disorder: A report on recommendations by the International Society of bipolar disorder (ISBD) older adults with bipolar disorder (OABD) task force(2023) MONTEJO, Laura; ORHAN, Melis; CHEN, Peijun; EYLER, Lisa T.; GILDENGERS, Ariel; MARTINEZ-ARAN, Anabel; NUNES, Paula Villela; OLAGUNJU, Andrew T.; PATRICK, Regan; VIETA, Eduard; DOLS, Annemiek; JIMENEZ, EstherObjectivesDespite the importance of psychosocial functioning impairment in Bipolar Disorder (BD), its role among Older Adults with BD (OABD) is not well known. The development of guidelines for the assessment of psychosocial functioning helps to facilitate a better understanding of OABD and can lead to better tailored interventions to improve the clinical outcomes of this population. MethodsThrough a series of virtual meetings, experts from eight countries in the International Society of Bipolar Disorder (ISBD) on OABD task force developed recommendations for the assessment of psychosocial functioning. ResultsWe present (1) a conceptualization of functioning in OABD and differences compared with younger patients; (2) factors related to functioning in OABD; (3) current measures of functioning in OABD and their strengths and limitations; and, (4) other potential sources of information to assess functioning. ConclusionsThe task force created recommendations for assessing functioning in OABD. Current instruments are limited, so measures specifically designed for OABD, such as the validated FAST-O scale, should be more widely adopted. Following the proposed recommendations for assessment can improve research and clinical care in OABD and potentially lead to better treatment outcomes.
- Gene expression alterations in the postmortem hippocampus from older patients with bipolar disorder-A hypothesis generating study(2023) NASCIMENTO, Camila; KIM, Helena Kyunghee; NUNES, Paula Villela; LEITE, Renata Elaine Paraiso; CRISTINA, De Oliveira Katia; BARBOSA, Andre; BERTONHA, Fernanda Bernardi; MOREIRA-FILHO, Carlos Alberto; JACOB-FILHO, Wilson; NITRINI, Ricardo; PASQUALUCCI, Carlos A.; GRINBERG, Lea Tenenholz; SUEMOTO, Claudia Kimie; BRENTANI, Helena Paula; LAFER, BenyBipolar disorder (BD) presents with a progressive course in a subset of patients. However, our knowledge of molecular changes in older BD is limited. In this study, we examined gene expression changes in the hippocampus of BD from the Biobank of Aging Studies to identify genes of interest that warrant further exploration. RNA was extracted from the hippocampus from 11 subjects with BD and 11 age and sex-matched controls. Gene expression data was generated using the SurePrint G3 Human Gene Expression v3 microarray. Rank feature selection was performed to identify a subset of features that can optimally differentiate BD and controls. Genes ranked in the top 0.1% with log2 fold change >1.2 were identified as genes of interest. Average age of the subjects was 64 years old; duration of disease was 21 years and 82% were female. Twenty-five genes were identified, of which all but one was downregulated in BD. Of these, CNTNAP4, MAP4, SLC4A1, COBL, and NEURL4 had been associated with BD and other psychiatric conditions in previous studies. We believe our findings have identified promising targets to inform future studies aiming to understand the pathophysiology of BD in later life.
