Default Sounds awfully familiar

From http://www.sciencedaily.com/releases...0401145312.htm

Einstein researchers contend that scientific evidence directly points to the locus coeruleus–noradrenergic (LC-NA) system as being involved in autism. "The LC-NA system is the only brain system involved both in producing fever and controlling behavior," says co-author Dominick P. Purpura, M.D., dean emeritus and distinguished professor of neuroscience at Einstein.


The locus coeruleus has widespread connections to brain regions that process sensory information. It secretes most of the brain's noradrenaline, a neurotransmitter that plays a key role in arousal mechanisms, such as the "fight or flight" response. It is also involved in a variety of complex behaviors, such as attentional focusing (the ability to concentrate attention on environmental cues relevant to the task in hand, or to switch attention from one task to another). Poor attentional focusing is a defining characteristic of autism.

"What is unique about the locus coeruleus is that it activates almost all higher-order brain centers that are involved in complex cognitive tasks," says Dr. Mehler.

Drs. Purpura and Mehler hypothesize that in autism, the LC-NA system is dysregulated by the interplay of environment, genetic, and epigenetic factors (chemical substances both within as well as outside the genome that regulate the expression of genes). They believe that stress plays a central role in dysregulation of the LC-NA system, especially in the latter stages of prenatal development when the fetal brain is particularly vulnerable.

Currently (2011) taking 200/50 Sinemet CR 8 times a day + 10/100 Sinemet 3 times a day. Functional 90% of waking day but fragile. Failure at exercise but still trying. Constantly experimenting. Beta blocker and ACE inhibitor at present. Currently (01/2013) taking ldopa/carbadopa 200/50 CR six times a day + 10/100 form 3 times daily. Functional 90% of day. Update 04/2013: L/C 200/50 8x; Beta Blocker; ACE Inhib; Ginger; Turmeric; Creatine; Magnesium; Potassium. Doing well.
