I have watched most of the series "Broken Brain" but was cut off mid stream on the final part (number 8). I have found it on google. The whole series has been incredibly educational with the newest research talked about. The brain has been understood more in the last 20 years than the last 2,000 years.
Hashimoto's Thyroiditis (hypothyroid + antibody/ies = Hashimoto's). can cause the toxins & inflammation from the gut to permeate the brain.
Recommended to watch sometime over the weekend
