Clinical Cohort Study of DHA in Neurodevelopmental Disorders
Neurodevelopmental disorders are a group of developmental disorders, including autism spectrum disorders (ASDs), attention deficit hyperactivity disorder (ADHD) and others, that begin at a developmental stage and severely affect the growth and development of the brain. Autism spectrum disorder (ASD) encompasses a group of neurodevelopmental syndromes characterized by deficits in social interaction and communication as well as repetitive behaviors and restricted interests. There is strong evidence for the involvement of inherited genetic factors in ASD (accounting for at least 80% of the variation in disease risk). There is strong evidence for the involvement of inherited genetic factors in ASD (accounting for at least 80% of the variation in disease risk). According to a meta-analysis, monogenic mutations in SHANK3, which encodes the major postsynaptic density (PSD) scaffolding protein at excitatory glutamatergic synapses, are found in approximately 0.69% of ASD cases and up to 2.12% of all moderate to profound intellectual disability cases. De novo mutations, interstitial deletions, and terminal deletions have been identified in ASD.
Recent studies have shown that children with ASD have significantly lower levels of docosahexaenoic acid (DHA) than those without. Studies have shown that higher DHA intake reduces the risk of schizophrenia, bipolar disorder, depression, anxiety disorder, and conduct disorders. After DHA treatment, most children with ASD showed clinical and biochemical improvements, with increased DHA levels as measured by blood analysis and significant improvements in social scale scores in the supplement group. Moreover, increasing DHA levels in children with ADHD through dietary supplements can improve behavior, attention, literacy, cognitive problems, and working memory function. Therefore, for neurodevelopmental disorders, high DHA intake may be an important component of disease prevention.

Plasma level concentration of DHA (μg/ml)
Time Frame: 1, 3, 6 months
|
Detection and analysis of free fatty acid substances were performed using an Agilent 7890B gas chromatograph system coupled with a Agilent 5977B mass spectrometer.

Change in developmental assessment
Time Frame: 1, 3, 6 months
|
Griffiths Mental Development Scales (Griffiths) were conducted by licensed and certified clinicians to assess developmental and cognitive level which is applicable to the children with mental age (not physical age) from 0 to 8. The developmental quotient in each zone represents the developmental status of the child. The higher the developmental quotient, the better the child's development. |
1, 3, 6 months
|
Change in autism severity assessed by DSM-5
Time Frame: 1, 3, 6 months
|
ASD severity was based on the DSM-5 administrated by certified clinicians.
The higher the score, the more severe the symptoms
|
1, 3, 6 months
|
Change in autism severity
Time Frame: 1, 3, 6 months
|
ASD severity was based on the ADOS-2 administrated by certified clinicians.
The higher the score, the more severe the symptoms
|
1, 3, 6 months
|
Change in social adaptation ability
Time Frame: 1, 3, 6 months
|
The scales of the Vineland II are organized within a three-domain structure: Communication, Daily Living, and Socialization. This structure corresponds to the three broad domains of adaptive functioning by the American Association of Intellectual and Developmental Disabilities: Conceptual, Practical, and Social. In addition, Vineland II offers a Motor Skills Domain and an optional Maladaptive Behavior Index to provide more in-depth information. The higher the score, the better the child's development |
