Brief Summary:
This project involves creating a novel and personalised BCI training system that targets social and communication difficulties, and inattentive symptoms problems often found in ASD/ADHD children. 20 participants between the age of 8 and 12 will be recruited and they will undergo 24 training sessions over an 8-week period. During these sessions, the children will play a computer game interface specifically designed to train attention and facial and emotional recognition, while using our BCI device. To further reinforce the treatment, the training system has been enhanced with the inclusion of an eye-tracker to target the lack of preferential eye contact that children with ASD exhibit. The investigators hypothesize that participants will show improvements in social skills and attention post treatment.
Detailed Description:
This pilot trial aims to improve attention levels in children with comorbid ASD/ADHD. Twenty participants aged 8 to 12 years with comorbid ASD/ADHD will be recruited. Most therapy involves at least a total of 20 sessions (4); as such, the intervention protocol includes 24 sessions followed by a follow up one month after completion. The participants will attend 24 brain training sessions over an 8-week period, playing computer games designed for improving attention, facial recognition, and emotion recognition.
Participants will be randomized to either the Intervention or Waitlist-Control study arm group, where the latter proceeds with training only after a wait-time of 8 weeks. The investigators hypothesize that participants in the Intervention group will show improved symptoms compared to the Waitlist-Control group at week 8. This pilot study will provide preliminary data to support the efficacy of the investigators new BCI-based training programme and potentially pave the way for a larger randomized controlled trial.
Children with comorbid ASD/ADHD have greater impairments in attention, social skills and eye gaze. The investigators believe that focusing on these symptoms might lead to potentially better treatment outcomes. Also, current treatments for ASD/ADHD are limited in that they are taxing, time-consuming, and incur side effects. If the BCI-based training programme has a positive impact on children diagnosed with ASD and ADHD, it can potentially be an alternative long-term treatment. Unlike medications and behavioural interventions, neurofeedback therapy has no side effects and may be more engaging for children. It has the potential to be made available eventually for use at the patient's own home and can therefore be administered at one's own time and convenience.
In 2010, the PI and his team conducted a pilot study to investigate a novel intervention for treatment of ADHD. The study involved subjects 7 to 12 years of age diagnosed with either combined or inattentive ADHD subtypes. The subjects received 20 sessions of BCI training over a 10-week period. The BCI training is an innovative design integrating neurofeedback system using an algorithm to analyze EEG brain waves, using it to drive a computer interface by sustaining a certain threshold of attention. Teachers of children in the intervention group reported larger improvements in the ADHD inattentive score although this was not statistically significant. Parents also fed back that the intervention was relatively safe to use and free of adverse effects.
In 2012, the team completed another study that improved upon the technology and investigated the feasibility of the new training programme (with a simpler headset using two dry lead sensors instead of an EEG cap) on 20 unmedicated ADHD children participants. The treatment intervention was intensified to 24 sessions over 8 weeks followed by 3 monthly booster training sessions. An additional component was added to the training module where participants were required to complete a stroop task calibration process before the training. This is to personalise the intervention and improve accuracy of the EEG parameters. In this open-label trial, parents reported statistically significant improvements in both inattentive and hyperactive-impulsive symptoms on the ADHD Rating Scale at 8 weeks, which further suggests the potential efficaciousness of the novel BCI-based training programme as a potentially efficacious treatment for ADHD.
In 2013, a larger-scale randomised controlled trial began to further investigate the efficacy of the BCI training on treating inattentive symptoms of ADHD. The randomized study aims to enroll 160 children between the age of 6 to 12 who will undergo 24 sessions of BCI training sessions over 8 weeks followed by 3 booster sessions. ADHD symptoms will be assessed primarily by blinded clinicians and parents as well as based on feedback obtained from respective school teachers. The study is currently ongoing and is estimated to complete by July 2016. Therapy using non-invasive BCI system-based games may represent an alternative treatment for children with ADHD and ASD. If demonstrated to be efficacious, parents are likely to prefer this as compared to current treatment modalities of medications (with potentially serious side effects) and behavior management (parents generally find this difficult and challenging). Children themselves are also more likely to enjoy the treatment and hence, comply better.
In the longer term, this approach and system may have potential for attention and cognitive enhancement for patients with cognitive impairment or early dementia.
