      Depression, Mental Health and Crisis Support   06/04/2017

      Depression, Mental Health and Crisis Support   Depression and other mental health difficulties are common amongst people on the autistic spectrum and their carers.   People who are affected by general mental health difficulties are encouraged to receive and share information, support and advice with other forum members, though it is important to point out that this exchange of information is generally based on personal experience and opinions, and is not a substitute for professional medical help.   There is a list of sources of mental health support here: <a href="http://www.asd-forum.org.uk/forum/index.php?showtopic=18801" target="_blank">Mental Health Resources link</a>   People may experience a more serious crisis with their mental health and need urgent medical assistance and advice. However well intentioned, this is not an area of support that the forum can or should be attempting to offer and we would urge members who are feeling at risk of self-harm or suicide to contact either their own GP/health centre, or if out of hours contact NHS Direct on 0845 4647 or to call emergency services 999.   We want to reassure members that they have our full support in offering and seeking advice and information on general mental health issues. Members asking for information in order to help a person in their care are seeking to empower both themselves and those they represent, and we would naturally welcome any such dialogue on the forum.   However, any posts which are deemed to contain inference of personal intent to self-harm and/or suicide will be removed from the forum and that person will be contacted via the pm system with advice on where to seek appropriate help.   In addition to the post being removed, if a forum member is deemed to indicate an immediate risk to themselves, and are unable to be contacted via the pm system, the moderating team will take steps to ensure that person's safety. This may involve breaking previous confidentiality agreements and/or contacting the emergency services on that person's behalf.   Sometimes posts referring to self-harm do not indicate an immediate risk, but they may contain material which others find inappropriate or distressing. This type of post will also be removed from the public forum at the moderator's/administrator's discretion, considering the forum user base as a whole.   If any member receives a PM indicating an immediate risk and is not in a position (or does not want) to intervene, they should forward the PM to the moderating team, who will deal with the disclosure in accordance with the above guidelines.   We trust all members will appreciate the reasoning behind these guidelines, and our intention to urge any member struggling with suicidal feelings to seek and receive approproiate support from trained and experienced professional resources.   The forum guidelines have been updated to reflect the above.   Regards,   The mod/admin team

Electrical Stimulation of the Brain

Check out this link. I wonder if the same technique can be applied to improve social skills, especially given this recent research? ;) Hopefully some uni's will get sufficient funding to research if there are any benefits to people on the spectrum.

I am likely to be modded if I say exactly what I think about this research... ;) It is flawed and quite ridiculous in sooooooo many ways. :wacko:

Why? (Not trying to lure you into being modded, just curious.)

Mumble you're welcome to say what you think as long as it's phrased reasonably politely!

Apart from the fact that we are playing with our brains in the same way as the 18th & 19th century quacks played with their patients bodies (ie: they have very little idea o9f wat they are doing and are just poking and prodding to see what happens, without any real understanding of what they are doing to the person as a whole :unsure: ), the problem I see with this particular study is the temporary nature of the improvement

I thought I would just say.I do not have a strong opinion on the issue.However unlike in the 18th and 19th century when some experiments were barbaric there are certain standards for research now. :)

I think in this case, we have a fairly good idea of what's happening. The parietal lobes are heavily involved in the processing of spatial information, and spatial information appears to underpin numeracy. Neurons transmit information via tiny electrical currents, so stimulating them is quite likely to enhance or diminish performance. This technique might be useful, not so much in improving the mathematical skill of people who aren't good at maths, but stimulating activity in neurons damaged by a stroke, for example.

 

It's important not to confuse the research with whacky reports about it in the media.

Yes, but did the assessment of numeracy/mathematics (I won't go into a debate about definitions of the two here... :whistle:) really assess attainment and gains in mathematics i.e. was this a valid test? The test, as far as I can make out from the reports (I haven't read the original research so I may be missing something), involved people learning abstract symbols which represented different numbers and then answering questions about which of two presented symbols was bigger (i.e. which represented a bigger number). Is this not more about either memory or about symbolic processing (and so more related to language acquisition)? Surely the mathematics involved, comparing two numbers (once you've translated the symbols) isn't being improved because this is already at a very basic level? :unsure: Why not use a standardised mathematics test of which several exist? Why not use the number system that the participants would be using in their everyday lives?

To those who want to investigate this further check out the science paper here.

 

Mumble, I also wondered about the testing method, however the linked report does justify the method very well. The science is sound and very promising imo.

I think your point about definitions is key here. Although the findings have implications for mathematics, numerical ability, spatial ability, memory and symbolic associations, those are secondary issues. The point of the paper (thanks to Fluffy for the link btw) was that a non-invasive technique could improve a specific cognitive process. Whether that process is involved in mathematics, numerical ability or symbolic associations would depend on how you define those things. The problem with using an extant number system or a standard mathematical test is that the operations involved are complex and it would be difficult to isolate the variables. Using a simple, novel abstract task gets round those problems.

Hi.I do wonder how easy it would be to replicate these results with people with ASD or children.Although with the'' students'' the process was none invasive as a parent of a child with AS I cannot imagine it being an easy process.Ben does not like the hairdressers,dentist or optician.I would have to see excellent results to justify the stress of having electrodes attached to his head and a mild electric current passed through.On top of which people with ASD are known to be upsett by sensory experiences that are not noticed by many individuals, who is to say they will not find the experience really unpleasant.

 

This study involved 15 people which is hardly a large sample.
