Early childhood atopy and autism risk

De profundis clamo ad te, domine
Regular readers will probably have heard something like this before so I'm sorry if I'm repeating myself: "The presence of any atopic disease in early childhood increased the risk of developing ADHD [attention deficit hyperactivity disorder]... and ASD [autism spectrum disorder]... in later life".

So said Mu-Hong Chen and colleagues [1] with yet another 'big data' paper coming out of Taiwan.

There is little point in me turning this research into some sort of mega-post given that this topic has featured so heavily on this blog. In case you missed them, here are some of the relevant posts:

  • Allergic and autoimmune diseases and autism (2012) (see here)
  • Asthma increases risk of ADHD? (2013) (see here)
  • Asthma as a risk factor for autism? (2014) (see here)
  • Autism, ADHD and allergy: Taiwan and big data (again) (2014) (see here)

Lazy? Yes, I am being a bit lazy in this post by just supplying older links but what more can I say apart from that there seems to be a complicated relationship between immune function and behaviour. Oh, and other research from this group might also be worthwhile looking at as per studies linking epilepsy and atopic dermatitis [2] and major depression and/or bipolar disorder and asthma [3] knowing about the various comorbidity relationships with autism (see here and see here).

And here is some lazy music to accompany my lazy post...
