Diffusion tensor imaging (DTI) has become a popular tool for delineating the location and extent of white matter injury in temporal lobe epilepsy (TLE). However, DTI yields nonspecific measures that are confounded by changes occurring within both the intracellular and extracellular environments. This study investigated whether an advanced diffusion method, restriction spectrum imaging (RSI) could provide a more robust measure of white matter injury in TLE relative to DTI due to RSI's ability to separate intraaxonal diffusion (i.e., neurite density; ND) from diffusion associated with extraaxonal factors (e.g., inflammation; crossing fibers). ⋯ RSI may provide a more specific measure of white matter pathology in TLE, distinguishing regions primarily affected by axonal/myelin loss from those where CFs and increases in extracellular water also play a role. By providing a more specific measure of axonal/myelin loss, RSI-derived ND may better reflect overall white matter burden in epilepsy.

Anxiety and depression are highly prevalent in people with epilepsy (PWE) and contribute to increased disability. Unfortunately, there are numerous barriers (e.g., cost, distance, and stigma) and service gaps (e.g., lack of services and trained clinicians) that prevent many PWE from accessing traditional face-to-face psychological services. The aim of the present study was to examine the feasibility of a new transdiagnostic Internet-delivered cognitive behavioral therapy (iCBT) program, the Chronic Conditions Course, to simultaneously treat symptoms of anxiety, depression, and disability. ⋯ The findings of the current study support the feasibility and potential of transdiagnostic Internet-delivered treatments for adults with epilepsy. Further large-scale controlled trials are warranted.
