has there ever been a condition that has had so many disparate 'causes' and 'cures' attributed to it? It makes me think that all of these stories aren't about the same disease at all.
Brain scans prove Freud right: Guilt plays key role in depression
June 4th, 2012 in Psychology & Psychiatry
http://medicalxpress.com/news/2012-06-b ... t-key.html
Scientists have shown that the brains of people with depression respond differently to feelings of guilt – even after their symptoms have subsided.
University of Manchester researchers found that the brain scans of people with a history of depression differed in the regions associated with guilt and knowledge of socially acceptable behaviour from individuals who never get depressed.
The study – published in the journal Archives of General Psychiatry – provides the first evidence of brain mechanisms to explain Freud's classical observation that exaggerated guilt and self-blame are key to understanding depression.
Lead researcher Dr Roland Zahn, from the University's School of Psychological Sciences, said: "Our research provides the first brain mechanism that could explain the classical observation by Freud that depression is distinguished from normal sadness by proneness to exaggerated feelings of guilt or self-blame.
"For the first time, we chart the regions of the brain that interact to link detailed knowledge about socially appropriate behaviour – the anterior temporal lobe – with feelings of guilt – the subgenual region of the brain – in people who are prone to depression."
The study used functional magnetic resonance imaging (fMRI) to scan the brains of a group of people after remission from major depression for more than a year, and a control group who have never had depression. Both groups were asked to imagine acting badly, for example being 'stingy' or 'bossy' towards their best friends. They then reported their feelings to the research team.
"The scans revealed that the people with a history of depression did not 'couple' the brain regions associated with guilt and knowledge of appropriate behaviour together as strongly as the never depressed control group do," said Dr Zahn, a MRC Clinician Scientist Fellow.
"Interestingly, this 'decoupling' only occurs when people prone to depression feel guilty or blame themselves, but not when they feel angry or blame others. This could reflect a lack of access to details about what exactly was inappropriate about their behaviour when feeling guilty, thereby extending guilt to things they are not responsible for and feeling guilty for everything."
The research, part-funded by the Medical Research Council (MRC), is important because it reveals brain mechanisms underlying specific symptoms of depression that may explain why some people react to stress with depression rather than aggression.
The team is now investigating whether the results from the study can be used to predict depression risk after remission of a previous episode. If successful, this could provide the first fMRI marker of risk of future depression.

How depressing is that? People who are already rich, famous, or successful don't need Honours. For the rest of us, Honours just remind us how poor, unknown, and unsuccesful we are!
.Ketamine 'exciting' depression therapy

Ketamine offers an avenue of research into a field that has struggled to find new treatments for depression
The illegal party drug ketamine is an "exciting" and "dramatic" new treatment for depression, say doctors who have conducted the first trial in the UK.
Some patients who have faced incurable depression for decades have had symptoms disappear within hours of taking low doses of the drug.
The small trial on 28 people, reported in the Journal of Psychopharmacology, shows the benefits can last months.
Experts said the findings opened up a whole new avenue of research.
Depression is common and affects one-in-10 people at some point in their lives.
Antidepressants, such as prozac, and behavioural therapies help some patients, but a significant proportion remain resistant to any form of treatment.
A team at Oxford Health NHS Foundation Trust gave patients doses of ketamine over 40 minutes on up to six occasions.
Eight showed improvements in reported levels of depression, with four of them improving so much they were no longer classed as depressed.
Some responded within six hours of the first infusion of ketamine.
Lead researcher Dr Rupert McShane said: "It really is dramatic for some people, it's the sort of thing really that makes it worth doing psychiatry, it's a really wonderful thing to see.
He added: "[The patients] say 'ah this is how I used to think' and the relatives say 'we've got x back'."
Dr McShane said this included patients who had lived with depression for 20 years.

The testing of ketamine has indentified some serious side-effects
The duration of the effect is still a problem.
Some relapse within days, while others have found they benefit for around three months and have since had additional doses of ketamine.
There are also some serious side-effects including one case of the supply of blood to the brain being interrupted.
Doctors say people should not try to self-medicate because of the serious risk to health outside of a hospital setting.
"It is exciting, but it's not about to be a routine treatment as where we need to be going is maintaining the response... it's not about to replace prozac."
However, it does offer a new avenue of research into a field that has struggled to find new treatments for depression.
'Something chemical'
David Taylor, professor of psychopharmacology at King's College London, told the BBC: "In these kinds of patients, spontaneous remission almost never happens, people going to these clinics are at the end of the road.
"It shows that depression is something chemical, that it can be reversed with chemicals, it dispenses for once and for all that you can just pull your socks up.
"What restricts it is the potential for disturbing psychological adverse effects and the route by which is given - intravenous - does restrict it to a small number of people."
He said in the future drug companies would develop a chemical that had the benefits, but without the side-effects, and that could be taken by something such as an inhaler.
The Home Office is reclassifying ketamine in the UK to be a class B drug, although it is already used in medicine for the treatment of back pain and as an anaesthetic
Indonesia: Clinics ready for depressed election losers

Baby accused of 'planning murder'
Hospitals and medical clinics around Indonesia have been told to get ready to receive depressed losing candidates after parliamentary elections on Wednesday, it's been reported.
"Most of the legislative candidates who will be prone [to depression] are beginners who are not ready to lose," says Fadhilah Masjaya, a hospital director in the city of Samarinda, the Jakarta Post reports. "Some of them probably have spent 1 billion rupiah ($88,000) alone - then it's wasted and they become distressed," she adds.
Last month, Social Services Minister Salim Segaf Al-Jufri called on hospitals to prepare special wards for losing candidates. "We predict that there will be a lot of distressed legislative candidates," he said. "Therefore we've coordinated with local administrations and hospitals to prepare special wards."
It's reported that across the country, more than 6,600 people are competing for 560 seats in the House of Representatives. But when all local elections are taken into account, there are apparently 19, 699 seats up for grabs with 200,000 people vying for them.
After the last elections in 2009, Indonesian media ran several stories about candidates suffering from depression, public breakdowns and even killing themselves. Most cases were attributed to debt people had taken on while campaigning.

New research finds that increasing fatty fish intake may be one way to improve the response rate among depressed patients who do not find antidepressants beneficial.
fish with garnish
The participants who ate the least fish tended to have the weakest response to antidepressants, whereas patients who had the most fish in their diet had the strongest response.
Up to half of patients with depression do not respond to selective serotonin reuptake inhibitor (SSRI) antidepressants.
Previous studies have suggested there may be an underlying genetic reason why up to 42% of cases do not respond to antidepressants. And in 2013, the journal Biological Psychiatry published an online risk calculator that estimated the likelihood of antidepressant response, based on the findings of the large STAR*D antidepressant trial.
The researchers behind the new study were investigating factors that influence antidepressant non-response when they hit upon an association between improved effectiveness and fish intake.
Lead researcher Roel Mocking explains the team's findings:
"We were looking for biological alterations that could explain depression and antidepressant non-response, so we combined two apparently unrelated measures: metabolism of fatty acids and stress hormone regulation. Interestingly, we saw that depressed patients had an altered metabolism of fatty acids, and that this changed metabolism was regulated in a different way by stress hormones." ...

Reminds me of what happened when I tried marijuana back in the day and discovered I have cannabis-induced psychosis. Can't go near the stuff.
