Neuroprotection is a process to preserve the neuronal structure and/or function against the death or gradual death of neurons, including the use of medicines and herbs.
In other words, neuroprotection protects the neuronal integrity against the reduction in the rate of neuronal loss over time inducing neurological disease, including neurodegenerative disease.
Neurodegenerative disease is the class of condition associated with the progressive loss of neuron occurred mostly in older adults, including dementia. The most common dementia in the US is Alzheimer`s disease (AD).
Alzheimer's disease is an irreversible, progressive brain disorder caused by the slowly lost of neuron in the brain that affects the memory and thinking skills and, eventually, the ability to carry out the simplest tasks as the disease progress into advanced stage.
According to the statistic, dementia affects over 47.5 million people worldwide, approximately 58 percent are living within low and middle-income countries.
Believe it or not, 5.8 million Americans of all ages are living with Alzheimer's dementia in 2019 and two-thirds of people with Alzheimer's disease are women.
Conventionally, as of today, there is no cure for dementia. Treatment of dementia is focusing to improve dementia symptoms and slow down the progression of the disease.
Some researchers suggested that the increased incidence of the onset of Alzheimer's disease over the past few decades may be correlated to the promotion of a high-fat diet in the US.
Dr. Rollins CPE, the lead scientist wrote, "HFD-induced obesity during adolescence exacerbated brain volume alterations by adult life in the 3xTg mouse model in comparison to control-fed mice and mediated volumetric alterations of select brain regions, such as the hippocampus".
And, "Further, HFD-induced obesity aggravated memory in all mice, lowering certain memory measures of B6129s control mice to the level of 3xTg mice maintained on a CD. Moreover, a decline in the volumetric trajectories of hippocampal regions for all mice was associated with the degree of spatial memory impairments on the MWM.".
Cranberry is an evergreen dwarf shrub, genus Vaccinium, belongings to the family Ericaceae, native to Northern America and Southern Asia.
Because of its health benefits, cranberry has been cultivated in some parts of the world for commercial profit and used in traditional and herbal medicine to treat wounds, urinary disorders, diarrhea, diabetes, stomach ailments, and liver problems.
On finding a potential compound for the treatment of the neurological disorder, researchers examined the efficacy of cranberry juice on the neuropsychologic functioning cognitively in older adults.
The 6-week, double-blind, placebo-controlled, randomized, parallel-group, clinical trial included 50 community-dwelling, cognitively intact volunteers, > or = 60 years old, with no history of dementia or significant neurocognitive impairments, randomly assigned to receive either 32 ounces/day of a beverage containing 27% cranberry juice per volume (n = 25) or placebo (n = 25).
According to the tested analysis at the end of 6 weeks experiment, there are no significant interactions between the cranberry and placebo groups compared to the baseline in standardized neuropsychologic assessments.
However, the subjective, self-report questionnaire where twice as many participants in the cranberry group showed a significant improvement of overall remembers abilities compared to placebo controls.
More precisely, 37.5% in the cranberry group rated their overall abilities to remember by treatment end as "improved" as compared to only 17.4% in the placebo controls.
Taken altogether, cranberry may be considered a remedy for the improvement of cognitive functioning, pending to the confirmation of the larger sample size and multicenter human study.
