You call your county's welfare dept at any time to get on the list. Also, the name of the service is now Home Care Waiver, a combination of the old Waiver 4 and Waiver 5 for people under the age of 60. I think it is important to note that, as with Passport, even with a doubled income cap, one has to have a fairly low income to qualify for this. When considering the current state of medical knowledge, and the incredible complexity of human physiology, it is readily apparent that we have a long way to go in understanding the interactions of factors involved with the multifactoral nature of disease. Positive scientific 'truth' is not really science.
Science is a dynamic evolving approximation of reality.
This article and the one that followed it about riluzole was talking about antiglutamatergic strategies. I assume that means reducing the levels of glutamate, which is involved in neuron transmission in the brain. I was reading something about an area of the brain I had never heard of the other day, called the Amygdala. It apparently has a role in the effects emotions, stress, fears, etc have on the body. It apparently releases quite a few different hormones, etc, including glutamate when we experience these things.
