    Not a recommendation at all.

    Only patient-reported scales were used and social network size information was not collected for healthy subjects.

    This sounds like something that would broadly reflect disease severity, wealth, living circumstances etc. Comparison with a control group adequate for this purpose hasn't been done so who knows whether this tells us anything about FND in particular as the authors seem to think.

    If I have a few thousand Twitter followers, does that mean my quality of life should be really good, then? Can I get better by getting more follows? (Sorry, I couldn't resist!)

    I would expect health to be a more significant determiner of social network size, regardless of the underlying aetiology, rather than the other way round as this article seems to be suggesting.

    Where are the normal controls, where are the comparators with identified biomedical neurological conditions?

    What is the relationship between social network size and these brain structures in normals?

    Where is the evaluation of social network size in the target patient population pre onset, and how is it impacted by their condition?

    Where is the evidence that the links between social network size and life success observed in a normal population are the same in specific patient groups?

    Also I can not be repeated too often that correlation is not causation.

    Even if there is a correlation between brain structure and social network size, the relationship between the two and of both of them to health is likely to be profoundly complex, and any link to the disabling impact of FND to be even more complex.

    Either people on here like @Peter Trewhitt are geniuses or these researchers are really really thick why can they not pick up these issues themselves?

    Still, at least they have a good sample size, right? Oh wait.
