A brief entry today and yet another blog post that starts with a quote (sorry)... "The offspring exposed to VPA [valproic acid] prenatally demonstrated a significant decrease in the number of play initiations/attacks and this was reversed with the KD [ketogenic diet]".Gloucester Old Spot @ Wikipedia That finding reported in the paper by Ahn and colleagues  continues my interest in all-things related to prenatal VPA exposure and the reported effects on some offspring (........

Attention deficit hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is a common childhood disorder. ADHD can often persist into adolescence and adulthood. The prevalence of ADHD is thought to be between 6-7% among children and adolescents and ~5% among adults (Willcutt, 2012).
Increasingly, evidence from multiple studies has pointed to comorbidity between ADHD and eating disorders (EDs). For example, one study found that young females with ADHD we........ Read more »

Acknowledging that some topics have the ability to furrow brows when it comes to autism research, mercury and autism is becoming something of a frequent talking point on this blog as a function of a whole slew of articles appearing in the peer-reviewed domain. If I were to [very tentatively] summarise the collected literature so far, it would be to say something like:Mosaic of mercury @ Wikipedia (i) there is quite a bit more research to be done on some sources of mercury being 'l........

No matter how careful we are, at some point in all of our lives we will develop sunburn. Despite all of the NHS campaigns and warnings that sun damage can cause skin cancer, many of us will know at least one person who forgoes using suncream and lets themselves bake in the sun in the quest for the perfect summer glow. But what is sunburn? And why is it so dangerous? First we need to take a look at our skin.... Read more »

New research suggests patients with both bipolar disorder and obsessive compulsive disorder should receive treatments for bipolar disorder alone.

In many countries around the world, codeine is available only on prescription. It’s a weak opioid, but can still cause addiction. Low dose codeine is also available in the UK, over-the-counter (OTC) in pharmacies.
