Can ω-3 fatty acids and tocotrienol-rich vitamin E reduce symptoms of neurodevelopmental disorders?

The incidence of childhood neurodevelopmental disorders, which include autism, attention-deficit hyperactivity disorders, and apraxia, are increasing worldwide and have a profound effect on the behaviors, cognitive skills, mood, and self-esteem of these children. Although the etiologies of these disorders are unclear, they often accompany genetic and biochemical abnormalities resulting in cognitive and communication difficulties. Because cognitive and neural development require essential fatty acids (particularly long-chain ω-3 fatty acids often lacking in mother's and children's diets) during critical growth periods, the potential behavior-modifying effects of these fatty acids as "brain nutrients" has attracted considerable attention. Additionally, there is compelling evidence for increased oxidative stress, altered antioxidant defenses, and neuroinflammation in these children. The purpose of this review is to provide a scientific rationale based on cellular, experimental animal model, observational, and clinical intervention studies for incorporating the combination of ω-3 fatty acids and tocotrienol-rich vitamin E as complementary nutritional therapies in children with neurodevelopmental disorders. Should this nutritional combination correct key clinical or biochemical outcomes and/or improve behavioral patterns, it would provide a safe, complementary option for these children.

Syndrome of allergy, apraxia, and malabsorption: characterization of a neurodevelopmental phenotype that responds to omega 3 and vitamin E supplementation.

OBJECTIVE: Verbal apraxia is a neurologically based motor planning speech disorder of unknown etiology common in autism spectrum disorders. Vitamin E deficiency causes symptoms that overlap those of verbal apraxia. Polyunsaturated fatty acids in the cell membrane are vulnerable to lipid peroxidation and early destruction if vitamin E is not readily available, potentially leading to neurological sequelae. Inflammation of the gastrointestinal (GI) tract and malabsorption of nutrients such as vitamin E and carnitine may contribute to neurological abnormalities. The goal of this investigation was to characterize symptoms and metabolic anomalies of a subset of children with verbal apraxia who may respond to nutritional interventions. DESIGN AND PATIENTS: A total of 187 children with verbal apraxia received vitamin E + polyunsaturated fatty acid supplementation. A celiac panel, fat-soluble vitamin test, and carnitine level were obtained in patients having blood analyzed. RESULTS: A common clinical phenotype of male predominance, autism, sensory issues, low muscle tone, coordination difficulties, food allergy, and GI symptoms emerged. In all, 181 families (97%) reported dramatic improvements in a number of areas including speech, imitation, coordination, eye contact, behavior, sensory issues, and development of pain sensation. Plasma vitamin E levels varied in children tested; however, pretreatment levels did not reflect clinical response. Low carnitine (20/26), high antigliadin antibodies (15/21), gluten-sensitivity HLA alleles (10/10), and zinc (2/2) and vitamin D deficiencies (4/7) were common abnormalities. Fat malabsorption was identified in 8 of 11 boys screened. CONCLUSION: We characterize a novel apraxia phenotype that responds to polyunsaturated fatty acids and vitamin E. The association of carnitine deficiency, gluten sensitivity/food allergy, and fat malabsorption with the apraxia phenotype suggests that a comprehensive metabolic workup is warranted. Appropriate screening may identify a subgroup of children with a previously unrecognized syndrome of allergy, apraxia, and malabsorption who are responsive to nutritional interventions in addition to traditional speech and occupational therapy. Controlled trials in apraxia and autism spectrum disorders are warranted.

Long chain polyunsaturated fatty acid levels in chronic illness.

Abnormal long chain polyunsaturated fatty acid (LCP) levels are found in children and adults who have several chronic diseases, due to restricted diets or possible abnormalities in metabolic pathways. In some cases, LCP supplementation is effective. Judy More looked at studies assessing LCP levels and supplementation in children with chronic diseases.

Apraxia of eyelid opening after bilateral stereotaxic subthalamotomy.

The case of a patient with apraxia of eyelid opening and blepharospasm occurring during the course of idiopathic torsion dystonia and previously treated with stereotaxic subthalamotomy is presented. The anatomic basis of this lid movement disorder is suggested to be located in the rostral brain stem. There was a considerable amelioration after treatment with trihexyphenidyl.
