Association between epilepsy and psychiatric disorders in adults with intellectual disabilities: systematic review and meta-analysis.

ABSTRACT:

Background

Psychiatric disorders, such as depression and anxiety, are commonly associated with epilepsy in the general population, but the relationship between psychiatric disorders and epilepsy among adults with intellectual disabilities is unclear.

Aims

To conduct a systematic review and meta-analysis to assess whether epilepsy is associated with an increased rate of psychiatric disorders in adults with intellectual disabilities.

Method

We included literature published between 1985 and 2020 from four databases, and hand-searched six relevant journals. We assessed risk of bias by using SIGN 50 and the Cochrane risk of bias tool. Several meta-analyses were carried out.

Results

We included 29 papers involving data on 9594 adults with intellectual disabilities, 3180 of whom had epilepsy and 6414 did not. Of the 11 controlled studies that compared the overall rate of psychiatric disorders between the epilepsy and non-epilepsy groups, seven did not show any significant inter-group difference. Meta-analysis was possible on pooled data from seven controlled studies, which did not show any significant inter-group difference in the overall rate of psychiatric disorders. The rates of psychotic disorders, depressive disorders and anxiety disorders were significantly higher in the non-epilepsy control groups compared with the epilepsy group, with effect sizes of 0.29, 0.47 and 0.58, respectively. Epilepsy-related factors did not show any definite association with psychiatric disorders.

Conclusions

It is difficult to pool data from such heterogeneous studies and draw any definitive conclusion because most studies lacked an appropriately matched control group, which will be required for future studies.

Project description:AimWomen during the postpartum period are at risk for psychiatric disorders such as postpartum depression (PPD), post-traumatic stress disorder (PTSD), and anxiety. It is controversial whether labour epidural analgesia have a protective role on PPD, PTSD, and anxiety or not. This study is a meta-analysis of previously published observational studies to investigate the association between epidural analgesia and PPD, PTSD, and anxiety.MethodsWe searched Cochran Library, PubMed, ProQuest, EMBASE, Scopus, Web of Science, PsycINFO, and MEDLINE from inception until December 2022. The outcome measures were positive screen of PPD, PTSD, and anxiety among women who received labour epidural analgesia. The Newcastle-Ottawa Scale was used to assess the quality of the observational studies. Statistical analysis was performed using Stata 17.0 software. The mean differences or odds ratios were pooled based on random effect.ResultsWe included 31 studies (12,064 women) in the review. The meta-analysis of PPD studies reported mean (standard deviation) showed no significant association between epidural analgesia and PPD (Mean Difference = 0.01; 95% Confidence Interval = -0.14 to 0.16; p-value = 0.88). The meta-analysis of PPD studies reported percentage showed no statistically significant difference in terms of the chance of depression between the exposed and non-exposed groups (Log Odds Ratio = -0.61; 95% CI = -1.48 to 0.26; p-value = 0.17). The meta-analysis of PPD studies reported OR showed indicate a lower chance of depression in the epidural group compared to the non-epidural group (Effect size = 1.01; 95% CI = 0.64 to 1.38; P-value = 0.00). In the case of PTSD, due to the heterogeneity of the tools and the methodology of the studies, it was impossible to reach a definitive conclusion and measure the studies in a meta-analysis. The meta-analysis of anxiety studies showed that no significant association between epidural analgesia and anxiety (MD = -1.36; 95% CI = -3.38 to 1.14; p-value = 0.29).ConclusionBased on the meta-analysis of observational studies, epidural analgesia for labour pain relief has no protective effect on postpartum psychiatric disorders.

Project description:ost adults with intellectual disabilities (ID) do not undergo genetic diagnostic investigation as part of their clinical care and have 'missed the boat' with regard to the WES and WGS genetic testing that is now being provided for children with ID. There is a dramatically increased risk of psychistric disorders in adults with ID, e.g. the risk of psychoses is 10X higher than in the general population. It remains an open question as to how much of adult ID is genetic in origin and how similar the genetic forms of adult ID are to those being diagnosed in children, in part due to survivor bias. There is also the opportunity to identify adults with treatable forms of ID, of which over 80 have been described, thus improving their clinical management. Furthermore, analysis of medical records of adults with genetic forms of ID can help to characterise the 'natural history' of individual disorders, resulting in more accurate prognoses for diagnosed children and identifying opportunities for improved management and possibly therapeutic intervention (e.g. optimal anti-epileptic therapy). Here we propose to exome sequence (to ~50X coverage) 200 adults with ID and co-morbid psychiatric disorders. This cohort has previously been assayed with chromosomal microarrays (Wolfe et al 2017 EJHG, 25, 66â€“72) identifying a diagnostic yield of ~11% which is comparable to the CNV diagnostic yield in various child ID cohorts (10-15%). The authors observed no substantive biases in diagnostic yield between different psychiatric diagnostic classes. The WES data will be analysed using the diagnostic workflows developed in the DDD study to ensure comparability between child and adult ID datasets. This study is intended as a pilot study to demonstrate the value of WES in adults with ID. This data is part of a pre-publication release.

Project description:Background: Autism spectrum disorder (ASD) is an early-onset and lifelong neurodevelopmental condition frequently associated with intellectual disability (ID). Although emerging studies suggest that ASD is associated with premature ageing and various medical comorbidities, as described for ID, data are scarce. Objectives: To determine the comorbidity burden and its association with distinct clinical presentation in terms of ASD severity, adaptive skills, level of autonomy, and drug exposure in a well-phenotyped sample of individuals with ASD-ID-the EFAAR (Frailty Assessment in Ageing Adults with Autism Spectrum and Intellectual Disabilities) cohort. Methods: A total of 63 adults with ASD-ID, with a mean age of 42.9 ± 15.1 years, were recruited from 2015 to 2017 from nine specialized institutions. They underwent detailed clinical examinations, including screening for comorbidities, ASD severity [Childhood Autism Rating Scale (CARS)], adaptive functioning [Vineland Adaptive Behavior Scale II (VABS-II)], autonomy [activities of daily living (ADLs)], and drug use [polypharmacy and the Drug Burden Index (DBI)]. The comorbidity burden was evaluated using the Cumulative Illness Rating Scale (CIRS-G) and its sub-scores [the severity index (CIRS-SI) and severe comorbidity (CIRS-SC)]. Results: We found a large range of comorbidities, including gastrointestinal disorders and mental and neurological diseases. Overall, 25% of our ASD-ID sample had chronic kidney disease with the associated increased cardiovascular risk factors. The comorbidity burden was high (mean CIRS-G total score of 10.6 ± 4.8), comparable with that observed among patients older than those in our population hospitalized in geriatric departments. Furthermore, the comorbidity burden positively correlated with age, decreased autonomy, and polypharmacy. Conclusion: The severity of the comorbidity burden associated with premature ageing in adults with ASD and ID highlight their crucial need of personalized medical care.
