Parkinson’s Disease: Dopamine Receptor Agonists and Monoamine Oxidase B Inhibitors



Parkinson’s disease is the second most common neurodegenerative disease behind Alzheimer’s disease. What is its pathophysiology? What are the pharmacological strategies towards treatment? Let’s find out!

  1. Dopamine also diffuses by volume transmission, and by reuptake, can resupply the damaged neuron.
    When you cover amphetamine, read the Wikipedia article. Normally a risky idea, this article is exceptional.

  2. it's tragic how stigmatized alzheimer's is to a point where people aren't even remotely aware of other neurodegenerative diseases. thank you for making this.

  3. Small correction at 8:28: L-DOPA crosses the blood–brain barrier because it's a substrate for an amino acid transporter called LAT1, not because it is more lipophilic than dopamine. If you compare their LogP, L-DOPA (-2.4) is much more polar/less lipophilic than dopamine (-1). Also L-DOPA can better survive peripheral metabolism to achieve therapeutically useful plasma concentrations, particularly with carbidopa, whereas dopamine undergoes extensive first-pass inactivation.

  4. Somthing to look forward to for me likely. To take it with a laugh. Best laughs, making ones sufering bearable treating it like a tragycomedy. Tears are for others. Like my persecuters with their sad sick laughs. Also funny like some rl evil gnomes.

  5. Thank you, we hope to understand idiopathic Parkinson’s better to prevent it in the future. It appears to involve environmental agents and peripheral immune system infiltration of the brain. I dedicated my life to neuroscience research when my mother was diagnosed with early onset Parkinson’s.

  6. Please please please do a video on Epilepsy if you plan on going after more neurological disorders. It’s really something that isn’t talked about enough and is heavily stigmatized in society…

  7. Parkinsons is notable for being one of the first neurological disorders for the FDA approved a non-pharmacological, technological treatment for reducing the symptoms of parkinsons: Deep Brain Stimulation.
    Looking forward to you returning to this if / when you do a neurology series.

  8. 4:28 I have a question. If the result of both the direct and indirect pathway is the same (stimulation of the thalamus), then why is there 2 pathways instead of just 1?

  9. The most famous person I know of who had Parkinson's disease is Micheal J. Fox, I was so sad that it basically ended his career as an actor. Back to the Future wouldn't be the same without him, IMO

  10. I just read The Brain In Search of Itself about the scientist who discovered the neuron.
    Its really a miniature electrical field, it really makes me wonder if there's more to electric stimulation the hamfisted gov tried years ago. With better tech,I think the cure uktimateky lies w electromagnectic therapy.

  11. With the amount of drugs i have used in the past 10 years i am 100% either going to get alzheimer or parkinson maybe even both together. I hope elon musks neurolink will improve in time for me to not make it a problem in my life. I think i have at least 20 or 25 years till the first symptoms to show. I am now still active in the weekends with 24/48 hours bender🥦🧪🧟‍♂️

  12. Neurodegenerative diseases scare the bejeezuz out of me. The body is gonna wear out regardless, but as long as I am still okay upstairs I can figure out ways to cope. There is a point where you could be so far gone, you don't know you would rather be dead.

  13. I was wondering if you could look at Dystonia. It's something I've struggled with my entire life so far, and I would love to learn more about how it affects the brain.

  14. my mom was diagnosed with parkinsons about 2 years ago. She's doing well and its progressing slowly but it's still hard to see. We think her first symptoms were over 10 years ago but it was easy to ignore or miss at first.
