Abstract
:
Spices and herbs have been used for medicinal purposes for centuries. Also, in the last
decades, the use of different nutritional supplements has been implemented to treat all kinds of diseases,
including those that present an alteration in cognitive functioning. Dementia is a clinical syndrome
in which a person's mental and cognitive capacities gradually decline. As the disease progresses,
the person’s autonomy diminishes. As there is not an effective treatment to prevent progressive
deterioration in many of these pathologies, nutritional interventions have been, and still
are, one of the most widely explored therapeutic possibilities. In this review, we have discussed a
great number of potentially interesting plants, nutritional derivatives, and probiotics for the treatment
of dementia around the world. Their action mechanisms generally involve neuroprotective effects
via anti-inflammatory, antioxidant, anti-apoptotic, b-amyloid, and tau anti-aggregate actions;
brain blood flow improvement, and effects on synaptic cholinergic and dopaminergic neurotransmission,
which may optimize cognitive performance in patients with cognitive impairment. As for
their efficacy in patients with cognitive impairment and/or dementias, evidence is still scarce
andthe outcomes are controversial. We consider that many of these substances have promising therapeutic
properties. Therefore, the scientific community has to continue with a complete research focused
on both identifying possible action mechanisms and carrying out clinical trials, preferably
randomized, double-blind ones, with a greater number of patients, a long-term follow-up, dose standardization,
and the use of current diagnostic criteria.
