Epilepsy and Alzheimer disease: New insights and perspectives.

Numerous epidemiological and pathophysiological arguments suggest a bidirectional link between late-onset epilepsy and Alzheimer's disease. However, the temporal and causal relationship between the pathophysiological processes underlying these two conditions remains unclear. It is likely that these connections are complex, requiring consideration of various scenarios of causality and reciprocity. In the absence of targeted therapies that effectively address the progression of both diseases, specific measures can be taken to improve patient care. These include screening for cognitive disorders in patients with late-onset epilepsy, detecting subclinical EEG activity in patients with Alzheimer's disease, and identifying and managing cardiovascular risk factors in both populations. Looking ahead, it is evident that global population aging and the potential demographic surge in these two patient groups will necessitate greater efforts to raise awareness and enhance the training of physicians and healthcare professionals in the emerging field of "epileptogeriatrics".
