Phytochemical Tocopherols Reduce the Risk of Alzheimer's disease and Age-Related Cognitive Decline in Vitamin E Deficient Adults

By Kyle J. Norton

Cognition is the process of the brain including the attention of working memory, producing and comprehending language, learning, reasoning, problem-solving, and decision making.

Cognitive impairment is a condition, that affects a person's thinking, communication, understanding, or memory. Cognitive impairment can be acute or chronic.

Acute cognitive impairment is a short-term health problem caused by delirium, an acutely disturbed state of mind due to drugs (toxicity and withdrawal), electrolyte disturbance, lack of drugs, liver disease, infection, reduced sensory input, intracranial urinary retention/fecal impaction or m Myocardial/metabolic/pulmonary.

Chronic cognitive impairment is a permanent medical condition associated with problems with language, ideomotor and constructive praxis, visual gnosis, spatial attention, learning abilities, and executive functions.

People with mild cognitive impairment (MCI) are at greater risk for the development of dementia, including Alzheimer's Disease.

According to the statistic provided by the Center for Disease Control and Prevention, more than 16 million people in the United States are living with cognitive impairment and these numbers are increasing at an alarming rate.

Sadly, the CDC continued, "An estimated 5.1 million Americans aged 65 years or older may currently have Alzheimer’s disease, the most well-known form of cognitive impairment; this number may rise to 13.2 million by 2050".

The causes of cognitive impairment are unknown. However, researchers suggested that aging, genetically mutated gene inherited from parents, such as Down's Syndrome, Fetal Alcohol Syndrome (FAS), autism, persistent mental health problems, together with unhealthy diet and lifestyle are associated with the onset of cognitive impairment.

Furthermore, hormonal imbalances, physical damage to the portion of the brain that is responsible for controlling cognitive function, and substance abuse are also some major causes of the development of the condition.

Tocopherols are phytochemicals of which many have vitamin E activity, belonging to the group of Lipids, found abundantly in butter, egg yolk, milk fat, some vegetable, seed or nut oils, etc.

On finding a potential phytochemical for the improvement of cognitive functioning, researchers determine the difference in blood tocopherol levels between patients with Alzheimer's disease (AD) or age-related poor cognitive function and health.

According to the examination of the results of 31 articles that were selected for the meta-analysis, patients with AD or age-related cognitive deficits and mild cognitive impairment (MCI) had lower circulatory concentrations of α-tocopherol compared with healthy controls.

Moreover, levels of β-, γ- and δ-tocopherols did not significantly differ between groups of AD and age-related cognitive deficits compared to controls.

Based on the findings, researchers suggested, "lower α-tocopherol levels have a strong association with AD and MCI supporting evidence for the role of diet and vitamin E in AD risk and age-related cognitive decline".

Taken altogether, tocopherols may be considered a supplement for the prevention and treatment of AD or age-related cognitive deficits and mild cognitive impairment (MCI) caused by vitamin E deficiency, pending the confirmation of the larger sample size and multicenter human study.

Intake of tocopherols in the form of supplements should be taken with extreme care to prevent overdose and acute liver toxicity.
