Andres Lozano: Parkinson's, depression and the switch that might turn them off

Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down — like a radio dial or thermostat — to correct dysfunction. A dramatic look at emerging techniques, in which a woman with Parkinson’s instantly stops shaking and brain areas eroded by Alzheimer’s are brought back to life. (Filmed at TEDxCaltech.)

  1. U have to provide the environment where by the body heals it's self , to do that you have to remove out all the blockages that hinder the Job of the fresh blood , Parkinson's is caused by smocking all types of smocking cigarettes weed Shishah and from medicines all chemical medicines have it's share in causing Parkinson's even the medicines that are subscribed for treating it have serious side effects , other by inhaling chemicals for a long time all types of chemicals cleaning chemicals industrial chemicals extra …. The human body is not designed to digest or even detox this chemicals from the body that's why it stays in the body and ends up in all areas and points that is not active physically in the human body …To remove this Toxins we use Hijjama treatment . U have to find a professional Hijjama Doctor and get it done from the first treatment the person will feel better ,,,it depends on the Doctor how many sessions a person need according to the condition … Hijjama mostly used for prevention and maintaining a healthy toxic free body …. Hijama treats many disease anything concerning the head from headache/ Alzahimar /Parkinson's , pains generally and more .

  2. excellent neurosurgeon around the world and his department is the best too. All the success for them.

  3. Go here https://www.madinamerica.com/2018/01/brain-implants-spinning-trial-results-protect-product/ and read on.
    Scary. The reporting on the results of experimental trial has been manipulated, conflict of interest not disclosed to patients, their adverse experiences misrepresented as "improved". Bad science. Chilling brave new world of lobotomy 2.0 may be upon us.
    Even lobotomy 1.0 was once hailed with Nobel prize – before the reality of the personality destroying brain surgery became obvious. I wonder why Dr. Lozano did not start his history intro with some cool lobotomy story.

  4. all in all, besides being obvious treatment, it's also a frontier for creating brain interfaces, some of them invasive, nonetheless they could lead to revolution in how people interact with technology. https://www.youtube.com/watch?v=LAtgp-_sNtg drum and bass made by me with fragments of that brilliant and warm speech, just an exercise, TEDs like these get me more addicted to TEDs

  5. Cannabis works for all of that too. The worst part is they are experimenting with methods that only treat symptoms in order to "normalize" people. The greatest artists and inventors in the history of humankind have most often been depressed, sometimes severely so. Maybe, just maybe, we should stop using the barbaric methods of trepanning and lobotomy and start looking for causes. Medicine isn't about the symptoms. This is a form of nerve stapling and is an abomination, even if it does help some people.

  6. May 2018. A lot has happened since 2013. Radio waves are being used to treat essential tremor. The treatment is non-invasive. No chance of infection.

  7. Check out the research approaching FDA approval to begin clinical trials for Parkinson's disease that transforms a patient's skin cells into dopamine producing neurons to replenish those lost in patients. www.SummitforStemCell.org

  8. TТhis simрlееее ‘triсссk’ rеvеeеrsеееs Alzheimеr’s in 14 dауууs https://twitter.com/9b7e19512eee5d182/status/822776974745550848

  9. I don't know any details of this other than the video I'm watching. To relief pain and horrible symptoms is looks great. My problem: Do we want humanity on switches. Do we want to turn on and off happiness and sadness, bravery or cowardice, good behaviour or bad behaviour. Could we have a president of USA who could be switched on to love or hate. I don't want humanity on switches but it's good for rare situations. But not for the direction of humanity itself. The boy who twists himself it made him walk again and that's good, but we need to know more of what it did, like change his thought pattern etc.

  10. I don't agree with these studies.  The results might show improvement in
    these individual's function, mood and/or cognitive function but how would this be regulated?  Laws and regulations can be put into place to discourage unlawful activity, not prevent it.  The one thing that Lozano says in his presentation that scares me about this technology is no neuron is safe from a neurosurgeon.  This is terrifying because if this surgery were to be used for the wrong reasons, doctors/scientists could potentially create a superhuman.  Also, there is no mention of failure rates.  I understand the video is promoting these procedures but to fully understand what these procedures entail there needs to be discussion of success rates vs. failure rates.  Brain surgery is a very delicate procedure and I would have to believe that mistakes are made and patients are the ones that suffer.  Is the risk of surgery equal to the benefits?  These studies would also have to prove that there is no chance that this technology would not be misused once installed. Overall I would say the risks outweigh the benefits and there needs to be more research posted or a better representation of the research as a
    whole.

  11. Dr Andres Lozano tenho minha vó que apresentou A doença de Alzheimer poderia se possivel agendar uma consulta com vc ?

  12. It's not all that simple, is it Doctor? All of your glittering generalities lead to false hope. What is the success rate? Nothing to brag about right? I also dispute your definition of Dystonia as a childhood genetic disorder in that it is just as likely not a childhood nor genetic disorder and you know it. And DBS is successful in a small number of cases at any age, isn't it? I'd prefer Truth to Showmanship please.

  13. I really came for that switch on depression, thinking it is a motivational switch, but it is a medical precise yew switch.

  14. Great explanation, prayers for the parents who can't afford such surgery/procedure for their children facing those problems.

  15. I'm concerned with some thoughts about this. Would you think that directly controlling pathological behavior, such as depression, would ultimately leave the patient better off. Well, of course, but are we equipping ourselves with the right tools to fight our neuroses and fits? Shall we take on an attitude where everything can be measured and determined? What are the consequences?

  16. I have just had DBS after living with PARKINSON'S DISEASE for 17 years. I was just 38 when first diagnòsed and over time it robbed me of my musicaĺ and teaching career, stole my hobbies and invaded my marriage. It ĺeft me wheelchair bound and a prisoner in my own home. Despite having remained positive fòr much òf that time towards the end Í was reaďý tò end my life as the quality was so poor and most òf the time ì was in tremendous pain from dystonia and dyskenesia. DBS has been my saviòur anď I çànñòt express iñ wòrds alonè mý gratitude to the piòneers of thìs proçedùrè and my own neurosurgeons whò used theìŕ skills to operate on me.

  17. My mom has Parkinson disease. How many on Parkinson disease have tried on? For surgery is the age is important? How much does it cost?

  18. Thank you for share this vídeo. I just link this to a paper with the title "How the brain changes in Parkinson’s Disease? Recent research from the University of Modena and Reggio Emilia answer this question about Parkinson's Disease". http://juanmoisesdelaserna.es/en/psicologia/brain-changes-parkinsons-disease

  19. One day, when all of this technology is cracked. Someone will realise that if children have this treatment that they will develop super human abilities. 

  20. Don't let them convince you this is fool proof. People still die from the operation and complications afterwards. Sometimes it doesn't work even when successful or very limited benefit. They tinker with my aunt's settings all the time trying to find that Goldilocks zone and she is never quite right. That being said a lot of people do see improvement so way the risk against the possible reward.

  21. How does one get on the list for the implantation of the electrodes to get help with the early onset of Alzheimer?

  22. @FreeFromWar Or the people who argue that misery or even general malaise are just part of the human condition, as if that is a fixed thing.  I also find there are a lot of people who are uncomfortable with the idea that most (if not all) of the suffering we deal with really is as 'simple' as less than optimally functioning circuitry in our brains instead of some ethereal thing like the mind.  Even agnostics or atheists.

  23. The next step will be non-invasive methods of achieving the same results, which there is good evidence that we can do via focussed electrical or ultrasonic stimulation, and then of course regenerating brain tissue or permanently rerouting brain circuitry to remove the need for continual stimulation altogether.
