Scientists have found that those suffering from Alzheimer's disease (AD) can enhance their mood with apple juice.
In the study, after institutionalized AD patients consumed two 4-oz glasses of apple juice a day for a month, their caregivers reported no change in the patients' Dementia Rating Scale or their day-to-day abilities.
What did change, however, was the behavioral and psychotic symptoms associated with their dementia (as quantified by the Neuropsychiatric Inventory), with approximately 27 percent improvement, mostly in the areas related to anxiety, agitation, and delusion.
While pharmacological treatments can provide temporary reduction in AD symptoms, they're costly and cannot prevent the ultimate decline in cognitive and behavioral function. That's why the authors considered it important to discover any possible nutritional interventions.
"The modest, but statistically significant, impact of apple juice on the behavioral and psychological symptoms of dementia in this study adds to the body of evidence supporting the usefulness of nutritional approaches, including fruit and vegetable juices, in delaying the onset and progression of Alzheimer's Disease, even in the face of known genetic risk factors," said the authors.
The study appears in American Journal of Alzheimer's Disease and Other Dementias (AJADD).
