I think could be cured if you excercise the brain to be mindful and analyzing correctly

Very nice of you to include one bullet point for psychosocial causal factors. Schizophrenia is the extreme end product of trauma. Of course, schizophrenia presents structural brain changes, but the brain is designed to respond to the environment (we'd be dead otherwise)! This video basically regurgitates the main falsehoods advanced by the psychiatric medical model which has been nothing short of a monumental failure. I would expect more from Khan Academy.

Ronald Pies, editor of the Psychiatric Times: "I am not one who easily loses his temper, but I confess to experiencing markedly increased limbic activity whenever I hear someone proclaim, "Psychiatrists think all mental disorders are due to a chemical imbalance!" In the past 30 years, I don't believe I have ever heard a knowledgeable, well-trained psychiatrist make such a preposterous claim, except perhaps to mock it. On the other hand, the "chemical imbalance" trope has been tossed around a great deal by opponents of psychiatry, who mendaciously attribute the phrase to psychiatrists themselves. And, yes, the "chemical imbalance" image has been vigorously promoted by some pharmaceutical companies, often to the detriment of our patients' understanding. In truth, the "chemical imbalance" notion was always a kind of urban legend—never a theory seriously propounded by well-informed psychiatrists."

The University of Maryland’s Ph.D. program in neuroscience concludes on its admissions webpage: “For many years, dopaminergic mechanisms were thought to play a pivotal role in schizophrenia, however, compelling evidence to support the integral participation of dopamine has been slow in coming.

Regarding the point mentioned at 12:52 about the psychosocial cause, it's no longer believed it's true. it is used to be called "schizophrenogenic mother" where family members (bw 1940-1970)  thought that their early relationship w/ their children may contribute to this disorder, but then after some research, this belief was proven invalid.  Source: crash course psychiatry 4th edition, pg 143

He kept calling them 'fluid-filled spaces', do they have an actual name?

they are called brain ventricles. the brain has two lateral ventricles, third ventricle, and fourth ventricle. https://en.wikipedia.org/wiki/Ventricular_system

Nicely explained. Do you think thin myelin sheath covering on the neurons could result in the smaller size of brain areas and contribute to the condition?

I'am a citizen who was arrested and tortured by psychiatrists. Psychiatrists have tried to kill me but I escaped at the last moment. Why did the psychiatrists arrest me ? well, that's because I discovered that : * Mental illness is caused by society * Psychosis is not a disease. * Paranoia is the first step in the right direction * Schizophrenia is a sign of good health Because I'm of arab origin and I discovered all these things they arrested me.

Good video; but nothing more annoying than actually having to wait for them to write the words. I like the new videos where they talk and write at the same time.

Just want to add that the very last thing he discussed is referred to as the downward drift hypothesis. Good luck everyone.

Most people are experiencing hallucinations these days. For instance, many peoples minds think that a car can change speeds, or that a car can stop moving all together. In actual fact, all objects, not just cars, are constantly moving, and they all move at one common speed. This constant ongoing motion takes place within a 4 dimensional environment known as Space-Time. However, that is not how the people whom are detached from the truth, and thus are detached from reality, actually see it. Today's physicists say that they admit that extreme embarrassment is still ongoing, and that this is the case since today's physicists still do not understand quantum mechanics, thus in turn they still have a multitude of possible explanations of what it is all about, instead of having the one and only correct explanation. So not even today's physicists can see the truth, and thus they too are still living in an imaginary reality.

Last night (3/9/17)  at 7:17 PM on 6th Ave and C Street near the 711 I screamed again.  I screamed to the public.  I hate feeling like I have to be going through something that is invisible to the eye.  I hate feeling I have to be manipulated by psychology because of how other people see it.  I hate feeling lost because of psychology.  I hate that I have to feel disabled because I hate female empowerment.  I hate feeling like a hospital dress because I hate the idea of having sex with a female. I hate feeling like a prescription because of the imagination. "It was called a 'worm' (although some thought 'virus' was a better description: the difference is based on the biological analogy that a virus works by infecting a host, whether a person or a computer programme, while a worm lives and replicates by itself.) (Cyber Spies: The Secret History of Surveillance, Hacking, and Digital Espionage by Gordon Corera Ch 7 Pg 135) This morning was my 10th time checking into St. Vincent de Paul Homeless Shelter.  I was offered a bed however due to not wanting to  miss my therapist appointment at 9 AM and I was told to come back this Monday at 8 AM to check back in.  However  after checking into the clinic to see the therapist  my appointment was rescheduled for today at 3:45 PM.    My last day at PATH is Thursday March 16 and I am hoping I can get back into St. Vincent de Paul for the second time. "A totalitarian government exercised power through computers, and so the resistance released a 'tapeworm' which replicated itself to destroy the network"(Cyber Spies: The Secret History of Surveillance, Hacking, and Digital Espionage by Gordon Corera Ch 7 Pg 139) I am still having masculinity issues as a openly gay man who was once a second generation trained dancer.  I don't know why as someone who performed the fairy tales as a submissive that has to mean I don't understand anything about manly order.  I don't understand why most men make me feel like I am a poor excuse to be a man because I am gay and practiced what I thought was an art form known as dance.   I don't know why I have to think it is empowering to have a sleazy point of view with men.  I hate feeling like a lost cause because of the imagination others have with dance and homosexuality.

Common? I guess you mean *relatively* common (i.e., relative to all mental disorders)?

Nicotine doesn't cause lung cancer; smoking does.
Gourab Bhattacharje (2 года назад)
+Jesse B. Sure. We can respectfully disagree. But, let me try one last time. Lung cancer: common side effects of nicotine. Google says: "Every year, approximately 200,000 people in the United States get lung cancer" .. now, US population is 310 million... 77% adult.. 17% adult smokes nicotine... approximately 41 million... 200,000 out of 40 million is 0.5% ... If we can say lung cancer is common among the smokers (0.5%), cannot we say 1% is a measure of 'common'? I understand if you say this is not affecting majority of the people. Well, luckily we dont deal with epidemics. Anyways, we may respectfully disagree. Have a great day.
Jesse B. (2 года назад)
+Gourab Bhattacharje OK, and I think you have a strange definition of "common" ... but I guess we'll have to agree to disagree here.

GHOST SIDE Please dont. Antidepressant drug escilatopram literally save my life. Anti psychotic risperidone literally made my world silence again from all negstive voices.

Large amount of distress and disability - mostly for the people related to the schizophrenic person by blood line. And doctors still overmedicate them. I don't have to be a doctor myself to notice the signs. I'm a paramedic anyway: drooling and muscle movements that are almost zombie-like in appearance are two signs of a person being overmedicated.
