If you suffer from chronic insomnia, you're three times more likely than someone without insomnia to have a sibling or parent with the same condition.
This suggests a potential biological predisposition to insomnia, so why are we regularly told that insomnia is a symptom of another underlying condition?
Furthermore, it is now understood that in about 10% of chronic insomnia cases, the cause is a deficiency of GABA (a neurotransmitter in the brain).
A 2010 study found that levels of GABA were 30% less in patients suffering from insomnia. This suggests that your biological makeup could be the cause of your insomnia.
This is interesting as it adds further weight to the argument that we need to stop assuming insomnia is a secondary condition. Sure, for some people it is - but we need to stop assuming this is the case for everyone.
All insomniacs are different and suffer with insomnia for different reasons. Let's hope we see more research undertaken on the link between GABA and insomnia, along with some new treatment options.
