About

In general ketogenic diet is a recognized as an efficient non pharmacological treatment for children with refractory epilepsy. However, in the last decade, it has been tried for many neurological disorders in children including ASD, neurodegenerative disorders.

Studies have shown that KD also helps in improvement of cognition, social skills, language function, and stereotypies. There is a limited number of reports of improvements after KD treatment, was insufficient evidence to attest the practicability of the KD as a treatment for ASD, but it is still a good indicator that this diet is a promising therapeutic option for this disorder. There are no major RCT's, hence raises concerns about the reliability and generalizability of findings. Majority of studies have used combined ketogenic diet therapy rather than single diet therapy and not many studies have compared add-on dietary intervention with standard of care. When compared to classic KD diet Modified Atkin's Diet is less restrictive, more palatable, more feasible and early response can be achieved. In summary, the rationale for conducting this study lies in the importance of add on dietary therapy in form of Modified Atkin's Diet along with standard of care for improvement of behavioral symptoms in children with ASD aged 3-8 years.

This study aims to provide valuable insights that it can improve behavioral symptoms in ASD, early and ultimately improve the developmental outcomes in these children.

Full description

• All the children presenting to Paediatrics OPD and Autism clinic in the Child Neurology division will be screened and those fulfilling the inclusion and exclusion criteria will be enrolled into the study

• Informed consent will be taken from parents for the study

• Baseline demographic details and following evaluation will be done -

  1. Autism severity assessment using CARS -2, ABC
  2. Neurocognitive assessment using (DQ/IQ/SQ) -VSMS
  3. Behavioral assessment using CBCL
  4. Sleep related issues using CSHQ After initial assessment children are randomized into Group I and Group II using computer generated random numbers.

Group I-Modified Atkin's Diet with standard of care arm

• Group I will receive Modified Atkin's Diet with standard of care whereas Group II will receive standard of care alone.

• Children randomized into Group I, initial workup for Modified Atkin's Diet will be done in the form of Electrocardiogram, Renal Function Tests, Liver Function Tests, Complete Blood Counts, Lipid profile, Urine calcium creatinine ratio and Ultrasound Pelvis for nephrocalcinosis. If pre KD work up is normal, then Modified Atkin's Diet will be initiated in the ratio of 1:1.

• Urine ketones will be checked daily using ketone dipsticks

• Telephonic contacts will be made in regular intervals every week to further ensure compliance at home, and to ensure proper understanding and confidence of parents

• Those children who are unable to tolerate taking adequate ketogenic diet therapy requiring discontinuation of therapy, will be considered as deviates

• First follow-up will be at 4 weeks of treatment initiation, followed by at 8, 12, 16, 20 and 24 weeks

• Compliance rate and adverse events will also be calculated from patient diary/log

• Those children who are unable to tolerate taking adequate ketogenic diet therapy requiring discontinuation of therapy, will be considered as deviates

• First follow-up will be at 4 weeks of treatment initiation, followed by at 8, 12, 16, 20 and 24 weeks

• Compliance rate and adverse events will also be calculated from patient diary/log

• Every alternate subject from each category, pre - intervention f MRI and 3 months post intervention f MRI is done (total 10 subjects) Group II -Standard of care arm

• Standard of care intervention plan will be devised for each subject based on the principles of -

• Behavioral therapy

  1. Behavioral modification techniques
  2. Psycho education
  3. Cognitive behavioral therapy
  4. Activity based interventions like eye contact exercises, attention enhancement exercises, self-help skills
  5. Speech therapy
  6. Parental training

• Occupational therapy

• Sensory integration therapy

• Pharmacotherapy - Anti-psychotic medications

• The parents of the children will be called telephonically every weekly to check for any issues and reinforcement to ensure appropriate regular behavioural intervention to be provided to the child.

• Physical follow up - 4, 8, 12, 16, 20, 24 weeks

• Follow up assessments - 12 weeks (3 months) & 24 weeks (6 months)

Functional MRI acquisition Every 4th subject from each group who provide consent for doing a f-MRI, will undergo a pre-intervention f-MRI and post-intervention f-MRI at 3 months follow-up (10 subjects in each arm, i.e. 20 subjects) These investigations would be done free of cost for the patients. The data will be compared with fMRI data of controls (retrospective data of children with dyslexia who received AI enabled-remedial intervention alone (for 6 weeks) as a part of a previous study by Dr Sayoni Roy Chowdhary, under the guidance of Prof Sheffali Gulati as Chief guide, after ethical clearance). The data will also be compared with the historical data of typical readers, acquired using the same f-MRI protocol at our center
