How Chewing Enhances Cognitive Function, Memory & Focus

In this video, I will be explaining how performing an activity as simple as chewing can enhance the function of the brain. Chewing Gum: https://amzn.to/2DRvTY9 or Frankincense: https://youtu.be/9O-WXLVoPQM both are able to improve the function of the brain by improving CNS blood flow and by stimulating the somatosensory cortices of the brain.

Patients with cognitive deficit have poor oral health and fewer teeth than cognitive normal elderly. The aim of the study was to investigate potential differences in masticatory (chewing) function between elderly with dementia and those with normal cognitive function... The results of the study shows a clear correlation between tooth loss and cognitive function in elderly of L’Aquila.

Mastication has been shown to promote and preserve general health, especially (and it seems involved in maintenance of) the cognitive function of the brain, beyond its primary functions of food intake and digestion. Research on aging and mastication have shown that the decrease of number of teeth and the impairment jaw muscle activity due to aging cause a reduction in sensory input activity to the central nervous system. Functional magnetic resonance imaging and positron emission topography revealed that mastication increases cortical blood flow and widely activates various cortical areas of the somatosensory, supplementary motor, and insular cortices, as well as the striatum, thalamus and cerebellum. Evidences suggest a possible relationship between mastication and brain function.

Elderly people are at risk factors for cognitive impairment and for developing Alzheimer’s disease (AD), which is one of the most common subtypes of dementia. Among the risk factors including ageing, illiteracy, lower level of education, lower socioeconomic status, head trauma, genetic factors, cardiovascular risk factors, overweight, smoking, hypertension and diabetes mellitus, an inactive lifestyle, surprisingly, loss of teeth showed significant importance. Mini-Mental State examination (MMSE) and the revised Hasegawa Dementia Rating Scale (HDS-R) has been used to evaluate higher brain function in standardized screening test. Recent data showed that masticatory ability and the number of natural teeth are related to cognitive function among the elderly without dementia.

The purpose of the present study was to investigate potential differences in masticatory function between elderly with dementia and those with normal cognitive function. In particular, we matched age and basic activities of daily living (B-ADL), masticatory function assessed in terms of the presence/absence of teeth, educational background, health general conditions (Blood pressure, diabetes, and renal diseases) and cognitive function (MMSE).

Research in animals and humans has shown that mastication maintains cognitive function in the hippocampus, a brain area important for learning and memory. Reduced mastication, an epidemiological risk factor for the development of dementia in humans, attenuates spatial memory and causes hippocampal neurons to deteriorate morphologically and functionally, especially in aged animals. Active mastication rescues the stress-attenuated hippocampal memory process in animals and attenuates the perception of stress in humans by suppressing endocrinological and autonomic stress responses. Active mastication further improves the performance of sustained cognitive tasks by increasing the activation of the hippocampus and the prefrontal cortex, the brain regions that are essential for cognitive processing. Abnormal mastication caused by experimental occlusal disharmony in animals produces chronic stress, which in turn suppresses spatial learning ability. The negative correlation between mastication and corticosteroids has raised the hypothesis that the suppression of the hypothalamic-pituitary-adrenal (HPA) axis by masticatory stimulation contributes, in part, to preserving cognitive functions associated with mastication. In the present review, we examine research pertaining to the mastication-induced amelioration of deficits in cognitive function, its possible relationship with the HPA axis, and the neuronal mechanisms that may be involved in this process in the hippocampus.
