I was misdiagnosed with dementia and while following suggestions to help myself I started taking coconut oil through out the day, total of 4 Tbsps. It not only stop the brain fog but my memory got better. A Neurologist later diagnosed me with anxiety and stress . If on low fat diets, brain is affected because it is Mosely made up of fat and you are negatively affecting the brain. Always get second opinion when diagnosed with dementia!!
