GLP-1s, Semaglutide, Tirzepatide and Current Research on Alzheimers, Parkinson’s, Inflammation, Kidney Disease and Addiction

Semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has emerged as a multifunctional therapeutic agent with potential benefits across diverse medical conditions. Here’s a synthesis of its current research and clinical implications on Alzheimer’s disease, Parkinson’s disease, Sleep Apnea, Inflammation, Addiction, and Kidney Disease. Research on these medications extends far and wide. At The Natural Path, we have used it mainly for weight loss, but have seen so many positive side effects with addiction, inflammation, sleep apnea, depression, anxiety, and alcohol use disorder.

Alzheimer’s Disease Research with Semaglutide and the GLP-1 Meds

• Reduced Risk in Diabetes Patients: Observational studies show semaglutide users with type 2 diabetes (T2D) have a 40–70% lower risk of Alzheimer’s diagnosis compared to other anti-diabetic medications, likely due to anti-inflammatory and metabolic effects.

• Phase III Trials: The EVOKE and EVOKE Plus trials, which test semaglutide in early Alzheimer’s disease, are scheduled to conclude in late 2025. Preclinical data suggest that neuroprotective effects are achieved through reduced neuroinflammation and amyloid-beta accumulation.

Parkinson’s Disease with Semaglutide and the GLP-1 Meds

• Mixed Clinical Results: A 2025 trial of lixisenatide (another GLP-1 agonist) showed modest motor symptom improvement in early Parkinson’s but with frequent gastrointestinal side effects.

• Preclinical Promise: In mouse models, semaglutide has been shown to reduce α-synuclein aggregation, improve motor function, and protect dopaminergic neurons, suggesting its potential neuroprotective effects.

Inflammation with Semaglutide and the GLP-1 Meds

• Systemic Anti-Inflammatory Effects: Semaglutide reduces key inflammatory markers (e.g., CRP, IL-6, TNF-α) in conditions like T2D, obesity, and COVID-19. It inhibits the NF-κB pathway and modulates immune cell activity.

• Clinical Impact: Linked to lower cardiovascular and renal risks, with trials showing reduced cytokine storms in severe infections.

Sleep Apnea with Semaglutide and the GLP-1 Meds

• Weight Loss-Driven Benefits: In obese patients, semaglutide users had a 40% lower risk of obstructive sleep apnea (OSA). A meta-analysis found it reduces apnea-hypopnea index (AHI) by 9.48 events/hour, partly due to weight loss and direct effects on respiratory function810.

• Comparative Efficacy: Tirzepatide (a dual GLP-1/GIP agonist) showed greater AHI reduction than liraglutide in some studies10.

Kidney Disease with Semaglutide and the GLP-1 Meds

• FLOW Trial Breakthrough: Semaglutide reduced risk of kidney disease progression by 24% and cardiovascular death by 5% in T2D patients with chronic kidney disease (CKD). This led to FDA approval in 2025 for CKD management1112.

• Mechanisms: Improved glomerular filtration rate (eGFR), reduced oxidative stress, and anti-inflammatory effects1213.

Addiction (Alcohol Use Disorder) with Semaglutide and the GLP-1 Meds

• Early Clinical Evidence: A 2025 trial found that semaglutide users drank two fewer drinks/day and reported fewer cravings. Preclinical studies show reduced alcohol intake in rodents via GABA modulation in brain reward pathways1415.

• Limitations: Most studies are small or observational; larger trials are needed to confirm efficacy16.

Weight Loss with Semaglutide and the GLP-1 Meds

• Sustained Efficacy: The STEP trials demonstrated 15–20% body weight loss over two years in obese patients, with improvements in waist circumference, blood pressure, and lipid profiles1718.

• Mechanism: Appetite suppression via hypothalamic signaling and delayed gastric emptying19.

Semaglutide and the GLP-1 Meds

Semaglutide’s benefits extend beyond glucose control and weight loss, showing promise in neurodegenerative diseases, inflammation-driven conditions, and addiction. While robust evidence supports its role in CKD and obesity, ongoing trials in Alzheimer’s and Parkinson’s may expand its therapeutic applications. Challenges include managing gastrointestinal side effects and confirming long-term safety in non-metabolic conditions.
