Low-dose CBD showed improvements in behavioral problems for some children with autism in a Turkish clinic

What This Study Found

Among 33 children treated with CBD-enriched cannabis (average 0.7 mg/kg/day), 32.2% showed decreased behavioral problems, 22.5% improved in expressive language, 12.9% improved in cognition, and 9.6% increased social interaction. No change was reported in 19.35% of patients.

Key Numbers

33 children; mean age 7.7 years; average CBD dose 0.7 mg/kg/day; median treatment 6.5 months; 32.2% improved behavior; 22.5% improved language; 12.9% improved cognition; 19.35% no change

How They Did This

Retrospective clinical report of 33 children (27 male, 6 female) with autism spectrum disorder treated with full-spectrum CBD (less than 3% THC) at a single center in Turkey from January 2018 to August 2020, with a median treatment duration of 6.5 months.

Why This Research Matters

With no approved drugs for core autism symptoms, families are increasingly turning to CBD. This real-world clinical data, while limited, adds to the emerging evidence base that low-dose CBD may help some children with behavioral aspects of autism.

The Bigger Picture

Multiple small studies from different countries are now reporting similar patterns of improvement in autism-related behavioral problems with CBD, building a case for larger controlled trials.

What This Study Doesn't Tell Us

No control group, very small sample, unblinded parent-reported outcomes, single center, variable treatment durations, no standardized outcome measures used.

Questions This Raises

  • ?Would these improvements hold up in a controlled trial with standardized measures?
  • ?Is the low dose (0.7 mg/kg) more effective or just safer than higher doses used in other studies?
  • ?What predicts which children will respond?

Frequently Asked Questions

Can CBD help children with autism?

In this small study, about a third of 33 children showed improved behavioral problems with low-dose CBD. However, without a control group, these results should be interpreted cautiously.

What dose of CBD was used for autism?

The average dose was 0.7 mg/kg/day, which is considerably lower than doses used in some other studies (average 3.8 mg/kg/day in the literature). The researchers noted no significant side effects at this lower dose.
