Background: Traumatic brain injury is associated with greater risk and earlier onset of dementia.
Objective: This study investigated whether later-life changes in subjective cognition and behavior - potential markers of Alzheimer disease - could be observed in cognitively unimpaired older persons with a history of suspected mild traumatic brain injury (smTBI) earlier in life and whether changes in cognition and behavior mediated the link between smTBI and daily function.
Methods: Data for 1392 participants from the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function, and Caregiving in Aging were analyzed. A validated self-reported brain injury screening questionnaire was used to determine the history of smTBI. Outcomes were measured using the Everyday Cognition scale (for subjective cognitive decline [SCD]), Mild Behavioral Impairment (MBI) Checklist, and Standard Assessment of Global Everyday Activities (for function). Inverse probability of treatment weighted logistic and negative binomial regressions were used to model smTBI (exposure) associations with SCD and MBI statuses, and Everyday Cognition-II and MBI Checklist total scores, respectively. Mediation analyses were conducted using bootstrapping.
Results: History of smTBI was linked to higher odds of SCD (odds ratio = 1.45, 95% confidence interval: [1.14-1.84]) or MBI (odds ratio = 1.75, 95% confidence interval: [1.54-1.98]), as well as 24% (95% confidence interval: [18%-31%]) higher Everyday Cognition-II and 52% (95% confidence interval: [41%-63%]) higher MBI Checklist total scores. Finally, SCD and MBI mediated approximately 45% and 56%, respectively, of the association between smTBI history and poorer function, as indicated by higher Standard Assessment of Global Everyday Activities total scores.
Conclusions: smTBI at any point in the life course is linked to poorer cognition and behavior even in community-dwelling older persons without MCI or dementia. Older persons with smTBI may benefit from early dementia risk assessment using tools that measure changes in cognition and behavior. Interventions for declining cognition and behavior may also be beneficial in this population to address functional impairment.
Background: Palliative care (PC) is the standard of care for patients with serious medical illnesses, or those conditions associated with high risk of mortality and negative impact on quality of life (QOL). Electroconvulsive therapy (ECT) is the gold standard treatment for certain psychiatric conditions, which may co-occur with serious medical illnesses. However, the use of "palliative ECT" (PECT) in this context is understudied.
Methods: We conducted a descriptive retrospective cohort study reviewing the indications, outcomes, and regimens of PECT. We included patients who had an ECT consultation, in addition to either a PC consultation or a do-not-attempt-resuscitation code status between 2018 and 2023.
Results: Thirty-one patients met our inclusion criteria, and 21 received ECT. The cohort was predominantly female (70%) with a mean age of 67.6 (range 25-90). Catatonia (64.5%) and treatment-resistant depressive disorder (35.5%) were the most common indications for ECT. At the time of ECT consultation, 16 patients (51.6%) had a serious medical illness, including cancer (19.4%) or end-organ disease (22.6%). Fourteen patients had major neurocognitive disorder (MNCD) (45.2%). Surrogate decision-makers consented for ECT in 64.5% of cases. All 21 patients who received ECT experienced psychiatric symptom improvement. ECT was associated with reduced mortality risk in 5 (23.8%) cases. Five patients initially misdiagnosed with MNCD experienced recovery in cognitive function after ECT, and the diagnosis was revised to depression-related cognitive dysfunction. Eight patients retained a comorbid MNCD diagnosis but experienced a mean Montreal Cognitive Assessment (MoCA) improvement of 5 points (range 0 to 17) with ECT.
Discussion: This work highlights the use of ECT among patients with serious medical illnesses, identifying cases when ECT was beneficial or deemed unsuitable. Patients with serious medical illnesses who also had an indication for ECT experienced improved QOL with ECT. Misdiagnoses, such as confusing depression-related cognitive dysfunction and catatonia for MNCD, were effectively addressed through ECT. The findings underscore the importance of cross-specialty collaboration between C-L psychiatry and PC.
Conclusions: Patients who receive PECT experience reduced suffering and improved QOL. PECT may be helpful in scenarios of life-threatening psychiatric illnesses, terminal medical illnesses with comorbid treatment-refractory psychiatric illnesses, and diagnostic uncertainty with MNCD.
Background: The End of Life Option Act (EOLOA) legalized medical aid in dying (MAID) in California in 2015. University of California, San Francisco Health initially implemented a policy requiring a mandatory mental health assessment of all patients seeking MAID, though this was not required by the EOLOA. State-level statistics on EOLOA are available, but less is known about outcomes at individual institutions and how institutional policy affects outcomes for patients seeking MAID.
Objectives: Investigators examined the factors contributing to patients' decisions to request MAID and how the mandatory mental health assessment impacted determinations of decisional capacity and access to MAID.
Methods: Retrospective chart review was conducted on a sample of patients who had pursued MAID or been prescribed MAID medications between June 2016 and May 2020 obtained by a combination of purposive sampling (n = 78) and systematic electronic health record sampling (n = 22). Descriptive statistics were used to examine demographic factors, neuropsychiatric diagnoses and rating scales, factors contributing to patients' decision to request MAID, and outcomes of the psychiatric evaluation process.
Results: Of the 78 patients in the purposive sample who had initiated EOLOA requests, 67% had MAID medications prescribed. Zero patients were found to lack decisional capacity due to a current psychiatric condition. Many patient records were missing relevant data including neuropsychiatric rating scale scores and factors contributing to patients' decision to request MAID. The neuropsychiatric rating scale scores and diagnoses that were present did not suggest a high prevalence of severe psychiatric illness in the sample.
Conclusions: The findings from this study suggest that mandatory mental health assessments for all patients requesting MAID at a single academic medical center did not identify patients who lacked decisional capacity to pursue MAID, and potentially created access barriers to seriously ill patients seeking this intervention. Generalizability of findings may be limited by the fact that mental illness burden was low in the studied sample. Results from this study contributed to changes in EOLOA institutional policy at University of California, San Francisco, including elimination of the mandatory mental health assessment for EOLOA candidates in favor of a conditional mental health assessment based on certain clinical criteria.
