Caregivers reported CBD improved seizures and non-seizure outcomes in severe epilepsy

Among 498 caregivers of patients with Lennox-Gastaut or Dravet syndrome, 85% reported seizure frequency improvements with CBD, plus significant non-seizure benefits in alertness (85%), emotional functioning (82%), and communication (74-79%), with 93% planning to continue.

What This Study Found

Caregivers reported improvements in seizure frequency (85%), seizure severity (76%), and seizure-free days (67%). Non-seizure improvements: alertness/cognition (85%), emotional functioning (82%), communication (74-79%), sleep (51%), ADLs (51%), physical functioning (46%). 18-56% of patients who had no seizure improvement still reported non-seizure benefits. 93% planned to continue CBD.

Key Numbers

498 caregivers (97% parents). Patients: mean age 16, median CBD dose 14 mg/kg/day, median 4 concomitant seizure medications. 16% achieved seizure freedom in past month. 93% planned to continue.

How They Did This

BECOME survey of 498 US caregivers of patients with LGS (80%) or DS (20%) treated with CBD (Epidiolex) for 3+ months. Cross-sectional online survey comparing current month to pre-CBD period using Likert scales.

Why This Research Matters

Clinical trials of CBD focused primarily on seizure reduction. This real-world survey reveals substantial non-seizure benefits that patients and families value, which may be an independent reason to continue treatment even when seizure control is incomplete.

The Bigger Picture

The finding that non-seizure improvements occurred even in patients without seizure reduction suggests CBD may have direct effects on cognition, alertness, and mood independent of its anticonvulsant properties. This could redefine how treatment success is measured in severe epilepsy.

What This Study Doesn't Tell Us

Retrospective caregiver report susceptible to recall and expectancy bias. No control group or blinding. Selection bias (caregivers who continue treatment are more positive). Likert scales provide subjective impressions, not objective measures.

Questions This Raises

  • ?Are the non-seizure benefits of CBD mediated through different mechanisms than its anticonvulsant effects?
  • ?Would objective cognitive testing confirm caregiver-reported improvements?

Frequently Asked Questions

Does CBD help with more than just seizures?

According to caregivers, yes. 85% reported improvements in alertness and cognition, 82% in emotional functioning, and 74-79% in communication, in addition to seizure benefits. Some improvements occurred even without seizure reduction.

How many patients become seizure-free on CBD?

In this survey, 16% achieved seizure freedom in the past month. However, 85% reported some improvement in seizure frequency, and 76% noted reduced seizure severity.
