“One way this occurs is through the activation of the glymphatic system which is a series of vessels that squirts cerebrospinal fluid throughout the brain and rinses away the toxic buildup of "stuff" that accumulates throughout the day.”

“Astrocytes, star-shaped cells found in the brain and spinal cord, use glucose to generate lactate, which is then utilized by neurons. In addition, exercise preferentially causes the brain to take up lactate.”

“The investigators injected the brains of mice with either lipopolysaccharide (LPS, an endotoxin that promotes acute inflammation) or 6-hydroxydopamine (a neurotoxin) and assessed the animals' brains for evidence of substantia nigra cell death.”

“Insulin-like growth factor-1, or IGF-1 for short, is a protein that plays critical roles in major growth pathways in the human body. It influences nearly every tissue in the body, especially developmental growth, skeletal muscle and neurons.”

“Lactate, which is produced during exercise, acts similarly to ketones, and under conditions of hypoxia (which can occur during exercise), it can be used as an alternate fuel source. In particular, lactate crosses the blood-brain barrier for use by neurons as an energy source.”

“Exercise can also help to manage the symptoms once the disease develops. Exercise activates pathways that are involved in maintaining connections between neurons, making them stronger and repairing damage.”

“Another study in which 22 year old men who engaged in four weeks of high-intensity interval training three days a week and supplemented with 150 milligrams of resveratrol per day, the lowest dose of the studies mentioned so far, did not promote increases in the men's aerobic or anaerobic capacity, exercise substrate utilization, or muscle fiber-specific adaptations compared to exercise alone.”

“But it also participates in the repair of muscles and neurons and promotes brain health. Directing IGF-1 toward its more beneficial processes through exercise may offer protection from its deleterious effects.”

“The pericyte cells, guardians of the barrier, have to physically get out of the way to respond to neuroinflammation, letting immune cells in and ultimately promoting leaks; this leads to a vicious cycle, culminating in the loss of capillaries and neurons.”

“Stress promotes neuronal cell death in the brain In the brain, corticotropin-releasing hormone increases the production of amyloid beta​, which aggregates and forms plaques in the brain, disrupting the synapses that form between neurons and promoting neuronal cell death.”
