OBJECTIVES: To evaluate dietary intake among individuals with and without attention-deficit hyperactivity disorder (ADHD), to evaluate the likelihood that those with ADHD have inadequate intakes.

METHODS:
Children, 7-12 years old, with (n = 23) and without (n = 22) ADHD, and college students, 18-25 years old, with (n = 21) and without (n = 30) ADHD comprised the samples. Children's dietary intake was assessed by a registered dietitian using 24-hour recalls over 3 days. College students kept a detailed food record over three days. Dietary information for both groups was entered into the Nutrition Data Systems for Research database, and output was analyzed using SAS 9.4. Nutrient analyses included the Healthy Eating Index-2010, Micronutrient Index (as a measure of overall micronutrient intake), and individual amino acids necessary for neurotransmission. Logistic regression was used to model the association of nutrient intake with ADHD. Models were adjusted for age, sex, IQ (or GPA), and energy intake (or total protein intake) as appropriate. Significance was evaluated at P = 0.05, and using the Benjamini-Hochberg corrected P-value for multiple comparisons.

RESULTS:
No evidence existed for reduced nutrient intake among those with ADHD compared to controls in either age group. Across both groups, inadequate intakes of vitamin D and potassium were reported in 95% of participants. Children largely met nutrient intake guidelines, while college students failed to meet these guidelines for nine nutrients. In regards to amino acid intake in children, an increased likelihood of having ADHD was associated with higher consumption of aspartate, OR = 12.61 (P = 0.01) and glycine OR = 11.60 (P = 0.05); and a reduced likelihood of ADHD with higher intakes of glutamate, OR = 0.34 (P = 0.03). Among young adults, none of the amino acids were significantly associated with ADHD, though glycine and tryptophan approached significance.

DISCUSSION:
Results fail to support the hypothesis that ADHD is driven solely by dietary micronutrient inadequacy. However, amino acids associated with neurotransmission, specifically those affecting glutamatergic neurotransmission, differed by ADHD status in children. Amino acids did not reliably vary among college students. Future larger scale studies are needed to further examine whether or not dietary intake of amino acids may be a modulating factor in ADHD.

BACKGROUND: Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common psychiatric disorders of the childhood is an early onset, affecting 2-18 % of the children worldwide. Etiopathogenesis of ADHD is obscure. In recent studies, low levels of vitamin D are found in association with many disorders as well as in neuropsychiatric diseases. In this study, we aimed to investigate serum vitamin D levels in pediatric ADHD patients.

METHODS: A total of 60 ADHD patients and 30 healthy controls were included in the study. Ages of the both groups were in 7 and 18 years old range. Serum levels of 25-OH-Vitamin D, calcium (Ca), phosphorus (P) and alkaline phosphatase (ALP) were investigated.

RESULTS: Serum levels of 25-OH-vitamin D were found to be significantly lower in children and adolescents with ADHD compared to healthy controls and no significant differences were found between the groups in terms of other variables. 25-OH-vitamin D level in ADHD group and control group was respectively; 20.9±19.4 ng/mL and 34.9±15.4 ng/mL (p=0.001).

CONCLUSION: Our results suggest that there is an association between lower 25-OH-vitamin D concentrations and ADHD in childhood and adolescence. Up to our knowledge this is the first study that investigate the relationship between vitamin D and ADHD in children.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. The classical treatment of ADHD where stimulant medication is used has revealed severe side effects and intolerance. Consequently, the demand to search for alternative treatment has increased rapidly. When comparing levels of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) in ADHD patients with those in age-matching controls, lower levels are found in ADHD patients' blood. ω-3 PUFAs are essential nutrients and necessary for a proper brain function and development. Additionally, there are strong indications that ω-3 PUFA supplements could have beneficial effects on ADHD. However, the results of ω-3 PUFA supplementation studies show a high variability. Therefore, we reviewed recent studies published between 2000 and 2015 to identify effective treatment combinations, the quality of design, and safety and tolerability of ω-3-containing food supplements. We searched the databases MEDLINE, PubMed, and Web of Science with keywords such as "ADHD" and "ω-3/6 PUFA" and identified 25 studies that met the inclusion and exclusion criteria.

The results of these ω-3 PUFA studies are contradictory but, overall, show evidence for a successful treatment of ADHD symptoms. Tolerability of the given supplements was high, and only mild side effects were reported.

In conclusion, there is evidence that a ω-3 PUFA treatment has a positive effect on ADHD. It should be added that treatment could be more effective in patients with mild forms of ADHD. Moreover, the dosage of stimulant medication could be reduced when used in combination with ω-3 PUFA supplements. Further studies are necessary to investigate underlying mechanisms that can lead to a reduction of ADHD symptoms due to ω-3 PUFA treatments and also to determine the optimal concentrations of ω-3 PUFAs, whether used as single treatment or in combination with other medication.

Half of ADHD children treated by Omega-3 RCT 2009

Omega-3/Omega-6 Fatty Acids for Attention Deficit Hyperactivity Disorder, A Randomized Placebo-Controlled Trial in Children and Adolescents
Journal of Attention Disorders March 2009 vol. 12 no. 5 394-401

Objective: The aim of the study was to assess omega 3/6 fatty acids (eye q) in attention deficit hyperactivity disorder (ADHD). Method: The study included a randomized, 3-month, omega 3/6 placebo-controlled, one-way crossover trial with 75 children and adolescents (8—18 years), followed by 3 months with omega 3/6 for all. Investigator-rated ADHD Rating Scale—IV and Clinical Global Impression (CGI) scale were outcome measures. Results: A majority did not respond to omega 3/6 treatment.
However, a subgroup of 26% responded with more than 25% reduction of ADHD symptoms and a drop of CGI scores to the near-normal range.
After 6 months, 47% of all showed such improvement. Responders tended to have ADHD inattentive subtype and comorbid neurodevelopmental disorders.
Conclusion: A subgroup of children and adolescents with ADHD, characterized by inattention and associated neurodevelopmental disorders, treated with omega 3/6 fatty acids for 6 months responded with meaningful reduction of ADHD symptoms. (J. of Att. Dis. 2009; 12(5) 394-401)

Less sun ==> more ADHD (March 2013)

Geographic Variation in the Prevalence of Attention-Deficit/Hyperactivity Disorder: The Sunny Perspective
Biological Psychiatry, doi:10.1016/j.biopsych.2013.02.010
Martijn Arns email address; Kristiaan B. van der Heijden, L. Eugene Arnold. J. Leon Kenemans
Received 6 December 2012; received in revised form 19 February 2013; accepted 19 February 2013. published online 25 March 2013.

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most common psychiatric disorder of childhood, with average worldwide prevalence of 5.3%, varying by region.

Methods: We assessed the relationship between the prevalence of ADHD and solar intensity (SI) (kilowatt hours/square meters/day) on the basis of multinational and cross-state studies. Prevalence data for the U.S. were based on self-report of professional diagnoses; prevalence data for the other countries were based on diagnostic assessment. The SI data were obtained from national institutes.

Results: In three datasets (across 49 U.S. states for 2003 and 2007, and across 9 non-U.S. countries) a relationship between SI and the prevalence of ADHD was found, explaining 34%–57% of the variance in ADHD prevalence, with high SI having an apparent preventative effect. Controlling for low birth weight, infant mortality, average income (socioeconomic status), latitude, and other relevant factors did not change these findings. Furthermore, these findings were specific to ADHD, not found for the prevalence of autism spectrum disorders or major depressive disorder.

Conclusions: In this study we found a lower prevalence of ADHD in areas with high SI for both U.S. and non-U.S. data. This association has not been reported before in the literature.
The preventative effect of high SI might be related to an improvement of circadian clock disturbances, which have recently been associated with ADHD. These findings likely apply to a substantial subgroup of ADHD patients and have major implications in our understanding of the etiology and possibly prevention of ADHD by medical professionals, schools, parents, and manufacturers of mobile devices.


ADHD children have low vitamin D levels (19 vs 29 ng) 2015

The Relationship between Serum Vitamin D Level and Attention Deficit Hyperactivity Disorder.
Iran J Child Neurol. 2015 Fall;9(4):48-53.
Sharif MR1, Madani M2, Tabatabaei F3, Tabatabaee Z4.

OBJECTIVE:
Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent mental health disorders. In recent years, the impacts of various micronutrients on ADHD have been studied. However, vitamin D has received much less attention. This study was aimed at evaluating the association and level of serum vitamin D in children with ADHD.

MATERIALS & METHODS: This case-control study was carried out, in 2012, on 6 to 12 yr-old children. Thirty-seven were children with ADHD in the cases group and another 37 healthy children were in the control group. Venous blood sample was drawn from each child to measure the serum level of vitamin D. Other variables were compared as well.

RESULTS: The mean serum vitamin D level of children with ADHD (19.11±10.10 ng/ml) was significantly lower than that of the control group (28.67±13.76 ng/ml) (P<0.001).
CONCLUSION:
Deficiency of vitamin D has been proved in various psychiatric diseases.
This study evidenced a significantly low level of serum vitamin D in children with ADHD.
This suggests the need for regularly monitoring of serum vitamin D levels and treatment of patients with vitamin D deficiencies.

BACKGROUND:Vitamin D status during prenatal brain development may influence risk of attention deficit and hyperactivity disorder (ADHD) symptoms in childhood. However, there are no prospective studies addressing this hypothesis. We aimed to examine whether maternal vitamin D status in pregnancy is associated with risk of ADHD-like symptoms in offspring.

METHODS: We conducted a prospective study analyzing data from 1,650 mother-child pairs from five birth cohorts embedded in the INMA Project (Spain, 1997-2008). Maternal vitamin D status in pregnancy was estimated by measuring plasma concentration of 25-hydroxyvitamin D3 [25(OH)D3] at 13 weeks of gestation. Children were assessed by teachers for ADHD-like symptoms at ages 4-5 years using the Diagnostic and Statistical Manual of Mental Disorders ADHD form list.

RESULTS: After adjustment, the number of total ADHD-like symptoms in children decreased by 11% per 10 ng/ml increment of maternal 25(OH)D3 concentration (incidence rate ratio [IRR] = 0.89; 95% confidence interval [CI] = 0.80, 0.98). Similarly, the number of symptoms in the ADHD subscales decreased in relation to higher maternal 25(OH)D3 concentration (IRR per 10 ng/ml increment = 0.89; 95% CI = 0.79, 0.99 for the inattention scale; and IRR = 0.88; 95% CI = 0.78, 0.99 for the hyperactivity-impulsivity scale). Using diagnostic criteria, we found an association of increasing maternal 25(OH)D3 with a lower risk of ADHD DSM-IV (relative risk ratio per 10 ng/ml increment = 0.87; 95% CI = 0.72, 1.06) and ICD-10 hyperkinetic disorder (relative risk ratio = 0.72; 95% CI = 0.49, 1.04) in children.

CONCLUSION: Higher maternal circulating levels of 25(OH)D3 in pregnancy are associated with lower risk of developing ADHD-like symptoms in childhood.

Objective: To examine the association between cord 25-hydroxyvitamin D2+3 (25(OH)D) and attention deficit hyperactivity disorder symptoms in toddlers, using Child Behaviour Checklist for ages 1.5–5.

Method: In a population-based birth cohort, a Child Behaviour Checklist for ages 1.5–5 questionnaire was returned from parents of 1233 infants with mean age 2.7 (standard deviation 0.6) years. Adjusted associations between cord 25(OH)D and Child Behaviour Checklist–based attention deficit hyperactivity disorder problems were analysed by multiple regression.

Results The median cord 25(OH)D was 44.1 (range: 1.5–127.1) nmol/L. Mean attention deficit hyperactivity disorder problem score was 2.7 (standard deviation 2.1). In adjusted analyses, cord 25(OH)D levels >25 nmol/L and >30 nmol/L were associated with lower attention deficit hyperactivity disorder scores compared to levels ⩽25 nmol/L (p = 0.035) and ⩽30 nmol/L (p = 0.043), respectively. The adjusted odds of scoring above the 90th percentile on the Child Behaviour Checklist–based attention deficit hyperactivity disorder problem scale decreased by 11% per 10 nmol/L increase in cord 25(OH)D.

Conclusion: An inverse association between cord 25(OH)D and attention deficit hyperactivity disorder symptoms in toddlers was found, suggesting a protective effect of prenatal vitamin D.

Autism treated by Vitamin D: Dr. Cannell - video June 2013

includes many reasons why he believes Autism is related to Vitamin D

  1. Both have strong inheritance features – Vitamin D about 60%
  2. Both have gotten substantially worse in last 30 years
  3. Vitamin D is known to be involved in brain development
  4. All autistic children are VitD deficient, but not all children who are deficient are autistic: genes are involved
  5. When giving vitamin D to cure children of rickets “mental dullness” decreases as well
  6. Children with genes which give them too much (Williams Syndrome) have to reverse of autism – too sociable
  7. Mothers having lots of fish (and thus more vitamin D) give birth to kids with less autistic symptoms
  8. Both associated with weak bones
  9. Both worse around the age of weaning
  10. Autism is more common in rich families – more likely to apply sun screen and stay indoors
  11. Autism increases with drugs which lower levels of vitamin D
  12. Seizures are common with Autism - Vitamin D has been shown to reduce seizures
  13. Fewer autistic symptoms (such as sleep problems) during summer: when child gets more vitamin D from the sun
  14. Both worse with latitude
  15. Both vary with Ultraviolet light
  16. Both vary with time of year (more birth of autistics in March in Northern hemisphere)
  17. 2X more urban autism – less UVB in urban environments
  18. Both worse with pollution
  19. Both worse with increased clouds and rain
  20. Both worse with closely spaced pregnancies
  21. Autistics have abnormal immune response – similar to that of vitamin D deficiency
  22. Low levels of vitamin D in mother animals reduces brain function in offspring
  23. Vitamin deficient rat pups have similar brain abnormalities to that of human autistic children
  24. Autistic children get less vitamin D in their blood for the same amount of sun exposure
  25. The 4 males/1 female ratio - Note estrogen increases vitamin D in the brain (testosterone does not)
  26. Both worse in African Americans (A-A 2-3 increased autism rate)
  27. Both worse in Dark-skinned immigrants in Europe

Elisabeth Toverud Landaas, Tore Ivar Malmei Aarsland, Arve Ulvik, Anne Halmøy, Per Magne Ueland, and Jan Haavik

Background: Micronutrients containing vitamins are reported to reduce symptom levels in persons with attention-deficit hyperactivity disorder (ADHD), but data on vitamin levels in ADHD are sparse.

Aims: To examine the relationship between vitamin concentrations, ADHD diagnosis and psychiatric symptoms in young adult ADHD patients and controls.

Method: Eight vitamins and the nicotine metabolite cotinine were analysed in serum samples from 133 ADHD patients and 131 controls aged between 18 and 40, who also reported ADHD symptoms and comorbid conditions.

Results: Lower concentrations of vitamins B2, B6 and B9 were associated with the ADHD diagnosis, and B2 and B6 also with symptom severity. Smokers had lower levels of vitamins B2 and B9.

Conclusions: ADHD patients were overrepresented in the group with low levels of some vitamins, possibly indicative of inadequate dietary intake of these micronutrients in a subgroup of patients. It is important to identify these patients in dietary intervention trials of ADHD.

Molecular resons that Vitamin D treats ADHD - Aug 2018

The molecular mechanism of vitamin D action in attention-deficit/hyperactivity disorder: a review of current evidences.

Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous disorder characterized by hyperactivity, impulsivity and inattention. Children with ADHD have challenges with learning, behavior and psychosocial adjustments retaining into adulthood. The exact etiology of ADHD is unknown and the pathophysiology of this disease is complex. Multifactorial hypotheses such as catecholaminergic and serotonergic systems disorders, neurotropic factors, some biological impairment with inflammatory and oxidative stress pathways are considered for ADHD. Some studies have shown that vitamin D level in children with ADHD is lower than healthy children; therefore, it may be involved in the pathogenesis of ADHD. Moreover, vitamin D has important effect on the inflammation, oxidative stress and some of neurotrophic factors and neurotransmitters; therefore, vitamin D supplementation may be effective in these children by facilitating dopaminergic and serotonergic function and some neurotrophic factors, as well as decreasing inflammation and oxidative stress.
