Background
Parkinson’s Disease (PD) is a chronic, neurodegenerative disease, caused by the progressive loss of midbrain dopamine neurons in the substantia nigra, which sends axons to the striatum. Approximately 1% of Americans are afflicted with PD, which give rise to more than $14 billion in medical-related costs each year. Symptoms include irreversible and impaired motor function, bradykinesia, lack of initiation of movement, and loss of balance. A significant loss of cortical mass, decrease in utilization of nutrients, and increase in Lewy bodies and dementia are non-motor symptoms that are commonly observed in advanced stages of PD. With the increasing number of cases per year, and the lack of therapies which delay or reverse neurodegeneration in PD, it is essential to develop disease-modifying therapies.
Description
Our researchers at the University of Nevada, Reno have developed a novel treatment method for alleviating symptoms and neurodegeneration associated with PD. Our method involves the combined use of different formulations of nootropic drugs Forskolin and Noopept to promote neuronal and cognitive repair. Using these compounds in mouse and in vitro PD models, we observed a therapeutic effect in alleviating symptoms and neurodegeneration associated with the disease. Forskolin is conventionally used as a weight loss supplement, and has also been shown to enhance protein kinase A (PKA) signaling. Due to its poor solubility in water, Forskolin is unable to pass the blood brain barrier (BBB). Therefore, our method involves the intranasal delivery of several isoforms of Forskolin, allowing for effective BBB penetration, followed by an oral dose of Noopept, which has cognitive enhancing activity for memory and learning facilitation. The combined use of these compounds enhances both PKA and brain-derived neurotrophic factor (BDNF), which are associated with stimulating cognition, dopamine synthesis, increases neuronal metabolism (glycolysis) and neuronal and synergize mitochondrial function/survival. Current therapies for Parkinson’s disease, including the use of L-DOPA, monoamine oxidase B inhibitors, and dopamine receptor 2 agonists. Unfortunately these methods are often associated with negative side effects and drug resistance. Additionally, these treatments only provide modest therapeutic effects in alleviating clinical symptoms, and unlike our treatment method, are not disease-modifying in targeting neurodegeneration.
