At baseline, PD patients showed lower CSF α-syn, Aβ, t-tau and p-tau levels than those of the controls. In all PD patients, CSF α-syn and Aβ decreased in a negative exponential pattern before the onset of motor symptoms, whereas CSF t-tau and p-tau, and serum NfL increased. Patients with cognitive impairment exhibited faster decline of […]

The results indicated that L. plantarum DP189 improved behavioral ability and increased the levels of 5-hydroxytryptamine and dopamine of PD mice. L. plantarum DP189 significantly increased the positive rate of tyrosine hydroxylase cells. L. plantarum DP189 activated the ERK2 and AKT/mTOR pathways, promoted the expression of Bcl-2, and inhibited the activities of Bax and Caspase 3. The results indicated that L. plantarum DP189
Microbiota-targeted interventions such as personalized diet, probiotics, or fecal microbiota transplantation (FMT) might represent a potential therapeutic option for AD. This review article discusses the procedure of FMT and its possible side effects on the recipient’s body. In addition, we review the role of FMT in the context of its application in various nervous system-related
Studies show that short – chain fatty acids have differenteffects by increasing or decreasing the quantity of certain molecules such as GLP-1,peptide YY, insulin, glucagon, ghrelin, leptin and serotonin while they also have animpact on the nervous system. Also is needed to emphasize its role in certainneurological diseases such as Parkinson, autism spectrum disorder and

Probiotic supplementation mediates these pharmacological effects by targeting a variety of cellular and molecular processes, i.e., oxidative stress, inflammatory and anti-inflammatory pathways, as well as apoptosis. Herein, we summarize the effects of probiotics on motor and non-motor symptoms as well as various cellular and molecular pathways in PD. CLICK TO REVIEW
Probiotics and the Treatment of Parkinson’s Disease: An Update Read More »
However, there is limited success in restoring healthy microbial biodiversity in AD and PD patients with general probiotics interventions and fecal microbial therapies. Fortunately, the gut microflora is susceptible to long-term extrinsic influences such as lifestyle and dietary choices, providing opportunities for treatment through comparatively individual-specific control of human behavior. In this review, weexamine the
CAP-related depression was accompanied by increased levels of NOx, LOOH, AOPP, and TRAP. In CAP participants, there was a strong correlation (r = 0.734, p < 0.001) between root canal LPS and the HDRS score. There were significant and positive associations between CAP or root canal endotoxin with the vegetative and physiosomatic symptoms of the
While commonly attributed to neuronal death in SNpc, postmortem studies have shown α-syn immunoreactivity and LB pathology inthe peripheral, central, and enteric nervous system (ENS).While the etiology of misfolded α-syn is unknown, variousgut microbiota and substrates are associated with α-syndysfunction. Gastrointestinal (GI) dysfunction, a commonfeature in the prodromal phase of PD patients, and histological evidence
Recently, particular attention has been paid to the possible function of three dietary patterns in AD prevention: the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH) diet, and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet. These dietary patterns have well-known anti-inflammatory and antioxidant properties, and their neuroprotective properties have been shown to be
One fundamental component of systemic homeostasis is the gut microbiota, which communicates withthe CNS via microbial metabolite production, the peripheral nervous system, and regulation oftryptophan metabolism. Over the past 10–15 years, research focused on the microbiota–gut–brainaxis has culminated in the discovery that dysbiosis, or an imbalance between commensal andpathogenic gut bacteria, can promote CNS pathologies.
