Гинго билоба не эффективен в профилактике болезни Альгеймера

Another large trial shows no benefit from ginkgo biloba extract in preventing Alzheimer disease, researchers report in the Lancet Neurology.

Nearly 2900 older adults without dementia who spontaneously reported memory complaints to their physicians were randomized to consume standardized ginkgo biloba extract or placebo for 5 years. Overall, the rate of diagnosis with probable Alzheimer's did not differ significantly between the ginkgo and placebo groups (1.2 and 1.4 cases per 100 person-years).

The authors note that a lower-than-expected Alzheimer's rate in both groups reduced the study's power, while a Lancet Neurology editorialist concludes: "For adults aged 70 years or older with a memory complaint who might be mildly cognitively impaired, use of [ginkgo biloba extract] does not decrease the risk of Alzheimer's disease over 5 years.

Researchers discovered a connection with stereotypic OCD behavior and vitamins and minerals. Dogs that received nutritional supplements, especially vitamins and minerals, with their food, chased their tails less.

“Our study does not prove an actual causal relationship between vitamins and lessened tail chasing, but interestingly similar preliminary results have been observed in human OCD,” said researcher Katriina Tiira, Ph.D.

However, there is no doubt that vitamin deficiencies can produce neurological and psychiatric disturbances. For instance, a lack of B12 can damage the central nervous system via changes in cytokine and growth factor production (Scalabrino, 2009). Thiamine deficiency is well-known for causing Wernicke's encephalopathy and Korsakoff's syndrome, disorders characterized by severe memory impairments. Previous studies have suggested that vitamins and minerals do have an effect on mood and perhaps even antisocial behavior Kaplan et al., 2007; Bohannon, 2009). The question here is whether broad-spectrum micronutrient treatments (i.e., nutritional supplements) can improve or "cure" bipolar disorder.

Truehope lists 17 published studies on the effectiveness of EMPowerplus™ in treating bipolar, ADHD, autism, and OCD. However, none of these studies is a randomized controlled trial that compares placebo to EMPowerplus™ in a double-blind fashion. Thus, it cannot be established that any improvements are due to the supplement, rather than to expectation or placebo effects.
