[Article of Interest] Schizophrenia: When Hallucinatory Voices Suppress Real Ones, New Electronic Application May Help
By Elin Fugelsnes/Else Lie; translation by Glenn Wells/Carol B. Eckmann.
Excerpt from the article: "Every one of us hears inner voices or melodies from time to time. The difference between non-afflicted individuals and schizophrenia patients is that the former manage to tune these out better," the professor points out.
If patients could learn to stifle inner noise it could have a huge impact on our ability to treat schizophrenia, he states. To this end, Professor Hugdahl’s research group has developed an application that can be used on mobile phones and other simple electronic devices, to help patients improve their filters.
Wearing headphones, the patient is exposed to simple speech sounds with different sounds played in each ear. The task is to practice hearing the sound in one ear while blocking out sound in the other. The application has only been tested on two patients with schizophrenia so far. The response from these patients is promising, Dr Hugdahl relates.
"The voices are still there, but the test subjects feel that they have control over the voices instead of the other way around. The patient feels it is a breakthrough since it means he can actively shift his focus from the inner voices over to the sounds coming from the outside," the professor explains.
[Article of Interest] Psychiatry Manual Drafters Back Down on Diagnoses
By Benedict Carey
The New York Times
Excerpt: The [doctors on a panel revising psychiatry’s diagnostic manual] dropped two diagnoses that they ultimately concluded were not supported by the evidence: “attenuated psychosis syndrome,” proposed to identify people at risk of developing psychosis, and “mixed anxiety depressive disorder,” a hybrid of the two mood problems. They also tweaked their proposed definition of depression to allay fears that the normal sadness people experience after the loss of a loved one, a job or a marriage would not be mistaken for a mental disorder.
“At long last, DSM 5 is correcting itself and has rejected its worst proposals,” said Dr. Allen Frances, a former task force chairman and professor emeritus at Duke University who has been one of the most prominent critics. “But a great deal more certainly needs to be accomplished. Most important are the elimination of other dangerous new diagnoses and the rewriting of all the many unreliable criteria sets.”
[Article of Interest] Death with Honors: Suicide among Gifted Adolescents
By James R. Delisle, Ph.D.
Department of Teacher Development and Curriculum Studies, Kent State University, Kent, Ohio.
Abstract: The incidence of suicide and suicide attempts among adolescents has increased markedly during the past two decades. Gifted adolescents, often perceived by others as being immune from problems of depression and emotional upheaval because of their high intelligence, have also shown increases in suicidal behaviors. On the basis of current research, the author contends that gifted young people are especially susceptible to suicide attempts.
Being an ex-drug-addict turned neuroscientist brings a unique insight into the physiological and phenomenological realities of addiction.
Excerpt: For 10 years I spun in and out of an addiction to opiates (and other drugs) that led to despair, crime, and the loss of everything I valued most—including my place in graduate school. After many failed attempts, I finally quit taking addictive drugs 30 years ago. I reentered grad school, got my PhD in developmental psychology, and became a professor at the University of Toronto, focusing on emotional and personality development. I studied these topics for 13 years, but I never quite understood my own personality development. I came to believe that my theories needed help from neuroscience, and that’s why I switched to research on the emotional brain—my focus for the past decade.
When I was in the throes of intense psychological addiction, my thoughts were continuously (and unpleasantly) drawn to drug imagery. It would be so great to have some now! How can I get some tonight?! But attraction to something you are just about to get feels marvelous. Dopamine-induced engagement turns into a headlong rush of triumph when the goal is finally accessible.
This perspective on the dual nature of attraction helps make sense of addiction. Unsated attraction can be a kind of torture, and addicts may seek drugs to put an end to that torture, more than for the modicum of pleasure drugs actually bestow.
Excerpt: Creativity of some artists is fuelled by the unique world view mental illness can provide, but without the completely debilitating aspects of the condition. Instead, the artists are able to direct their creativity into artistic projects.
