Альтернативные методы коррекции СДВГ

Bacopa monnieri is an Ayurvedic medicinal herbal widely used as a tonic and memory enhancer. In a small 12-week double-blind RCT, 36 children with ADHD randomized to receive Bacopa, 50 mg BID, showed significant improvement over placebo in tests of sentence repetition, logical memory, and pair-associative learning.

A standardized extract of the bark from the French maritime pine (Pinus pinaster) may also help reduce symptoms of ADHD. A total of 61 children and adolescents randomized to a standardized extract of French maritime pine bark (Pycnogenol™), 1 mg/kg/d, for 1 month, experienced significant improvements in hyperactivity, inattention, and visual-motor coordination compared with placebo recipients; symptoms returned to pre-treatment baseline levels after a 1-month washout.

There is also promising evidence that zinc supplementation may mitigate ADHD symptoms. In a large 12-week double-blind placebo controlled trial (N = 400), children and adolescents randomized to a high dose of zinc, 150 mg/d, experienced significant improvement in hyperactivity and impulsivity but not inattention over placebo. In an augmentation study, the addition of zinc to methylphenidate resulted in greater improvement than methylphenidate alone.

Роль минеральных веществ в патогенезе психических расстройств

Early studies showed that women affected by chronic depression sometimes have copper, zinc, and cesium deficiencies [37,38]. Later studies suggest that the presence of depression and other neuropsychiatric symptoms is due to the deposit of copper in the central nervous system [39]. Eggers et al. [40] used SPECT to demonstrate a reduction in thalamichypothalamic presynaptic dopamine and serotonin transporters due to the accumulation of copper. There was a negative correlation between the density of presynaptic dopamine transporters and the severity of depression as assessed using the Hamilton Rating Scale for Depression.

It was recently hypothesized that trace elements play an important role in the pathogenesis of

bipolar disorders by causing neurodegeneration [41]. Moreover, essential elements like vanadium have been implicated as a causative factor for bipolar mood disorder, while elevated vanadium and molybdenum levels have been reported in serum samples from bipolar mood disorder patients [41]. This latter study showed, using DSM-IV standard diagnostic criteria and classification into types I, II, and V according to the concept of Young and Klerman, that Na, K, P, Cu, Al, and Mn were elevated significantly in Bipolar I (Mania) (P < 0.001). In Bipolar II hypomania, Na, S, Al, and Mn were increased significantly (P < 0.02), while in Bipolar II depression, Na, K, Cu, and Al were increased significantly (P < 0.001). Finally, in Bipolar V, Na, Mg, P, Cu, and Al were increased significantly (P < 0.002) compared to a control group [41]. A recent study by Gonzales-Estecha and colleagues [21] found higher serum copper and zinc, blood lead and cadmium, and urine lead, cadmium, and thallium concentrations in patients diagnosed with bipolar disorders compared to a control group.

Increased neuronal oxidative stress (OxS) induces deleterious effects on signal transduction, structural plasticity and cellular resilience, mostly by inducing lipid peroxidation in membranes, proteins and genes [42]. It has been hypothesized that these pathological processes occur in critical brain circuits that regulate affective functioning, emotions, motoric behavior and pleasure involved in bipolar disorder (BD) [43,44].

The brain is particularly vulnerable to oxidative damage since it contains large amounts of polysaturated fatty acids and possesses low antioxidant capacity [45]. Several studies have demonstrated altered OxS parameters in the pathophysiology and therapeutics of BD, including changes in the levels of enzymes superoxide dismutase (SOD), catalase (CAT) and thiobarbituric acid reactive substances (TBARS) [46]. The well-known stabilizing agent Lithium was found to limit the enzyme activity, potentially lowering hydrogen peroxide and hydroxyl radical formation. Similarly, lithium was also shown to reverse increased OxS parameters in BD [43,47]. For instance, a decline in lipid peroxidation and an increase in CAT levels were observed in valproate and lithium-treated rats [42,48]. Accumulation of copper was shown to increase oxidative stress in bivalve species [49]. In skeletal muscle of Broilers Under Heat Stress, copper decreases because of dietary Selenium, Vitamin E, and their combination with an increase in antioxidant defense [50]. In humans accumulation of copper was associated with oxidative stress in allergic asthma patients, and introduction of nutritional supplement therapy accompanies improved oxidative stress, immune response, pulmonary function, and decrease in copper plasma levels [51]. On the other hands copper levels were elevated in several brain areas in a degenerative disease such as Niemann-Pick C [52]. Interestingly, Nieman-Pick C disease was specifically indicated to be associated with Bipolar Disorders [53]. If the results of our study are further confirmed, it will lend significant support to the hypothesis that minerals such as copper play an etiological role in psychiatric disorders, and WD may serve as a pathogenic model for the bipolar disorder.
