Epilepsy in the older patient

Epilepsy and mortality: a retrospective cohort analysis with a nested case-control study identifying causes and risk factors from primary care and linkage-derived data

OBJECTIVES

People with epilepsy (PWE) have a higher mortality rate than the general population. Epilepsy-related deaths have increased despite all-cause mortality decreasing in the general population pre-COVID-19. We hypothesised that clinical and lifestyle factors may identify people more at risk.

DESIGN

We used a retrospective cohort study to explore cause of death and a nested case-control study to identify risk factors.

SETTING

We explored factors associated with mortality using primary care population data from 1 April 2004 to 31 March 2014. Data were obtained from the Clinical Practice Research Datalink which compiles anonymised patient data from primary care in the UK. Cause of death data was supplemented from the Office of National Statistics when available.

PARTICIPANTS

The analysis included 70 431 PWE, with 11 241 registered deaths.

RESULTS

The number of deaths within the database increased by 69% between the first and last year of the study. Epilepsy was considered as a contributing cause in approximately 45% of deaths of PWE under 35. Factors associated with increased risk of death included attendance at emergency departments and/or emergency admissions (OR 3.48, 95% CI 3.19 to 3.80), antiepileptic drug (AED) polytherapy (2 AEDs: OR 1.60, 95% CI 1.51 to 1.71; 3 AEDs: OR 2.06, 95% CI 1.86 to 2.29; 4+AEDs: OR 2.62, 95% CI 2.23 to 3.08), status epilepticus (OR 2.78, 95% CI 1.64 to 4.71), depression (OR 1.67, 95% CI 1.57 to 1.76) and injuries (OR 1.54, 95% CI 1.43 to 1.67). No seizures in the prior year (OR 0.52, 95% CI 0.41 to 0.65).

CONCLUSION

Our results add to existing evidence that deaths in epilepsy are increasing. Future studies could focus on identifying PWE at high risk and addressing them with clinical interventions or better self-management. Identifying specific risk factors for younger people should be a priority as epilepsy may be a factor in close to half of deaths of PWE under 35 years of age.

Best care for older people with epilepsy: A scoping review

There are two peaks of diagnosis of epilepsy: in childhood and in people over 65. Older people may have complex needs like co-morbidity, polypharmacy, frailty, and social isolation. This scoping review focusses on the care of older people with epilepsy beyond diagnosis and medical treatment. We sought to identify areas within the UK health service needing development either in clinical practice or through further research. The search returned 4864 papers with 33 papers included in the review. The papers were grouped into psychosocial, self-management and services themes. Only one randomised controlled trial was found. Research was mainly based on cohort and case-control studies. Older people require more information to self-manage epilepsy and more psychological support to help with symptoms of anxiety and depression. People reported experiencing stigma and a reluctance to disclose their condition. This may increase the risk of isolation and difficulties in managing epilepsy. Studies reported that older people are referred less to neurologists, suggesting there may be a gap in care provision compared to younger people. Generalist health professionals may be better placed to provide holistic care, but they may need additional training to alleviate uncertainties in managing epilepsy. Care plans could help provide information, particularly for co-morbidity, but few had one. Our findings highlight psychological and self-management needs for managing epilepsy in older people. Health service staff may require upskilling to shift epilepsy management from neurologists to generalists. More research is needed regarding psychological and self-management interventions, particularly in the form of randomised controlled trials.
