Probiotics in Early Life May Prevent ADHD

Research over the last decade has confirmed that the health of our gut can have a significant effect on both our physical and mental wellbeing.

It is acknowledged that the gut and brain communicate and when there are disturbances in either, the other will be adversely affected.

Our digestive system helps with the absorption of essential nutrients which are important for the production of all our hormones. Our digestive system also plays a crucial role in our immune system. In fact, 90% of our immune system is located in our gut.

The bacteria in our gut (also known as gut flora or probiotics) has a major role in the regulation of our immune system and imbalances in our gut flora is associated with several health conditions. These include mental health disorders such as depression, anxiety, schizophrenia, autism and attention deficit hyperactivity disorder (ADHD).

A very interesting study published in the journal, Pediatric Research, investigated the effects of probiotic supplementation for the prevention of ADHD and Asperger syndrome (a type of autism) in children [1].

Seventy-five infants received either a placebo or a probiotic supplement (Lactobacillus rhamnosus GG) for the first 6 months of life. They were then followed up until the age of 13 years.

At the age of 13 years, 17% of infants given the placebo were diagnosed with ADHD or Asperger syndrome. However, in children receiving the probiotic supplement none were diagnosed with these conditions.

The researchers concluded that probiotic supplementation early in life may reduce the risk of neuropsychiatric disorders in childhood.

While further research into the benefits of probiotic supplementation for these neuropsychiatric disorders is required, it seems that probiotic supplementation may be beneficial (along with a healthy diet).
