Research Interests
Dr Anderson's neurochemistry research laboratory performs a range of monoamine-related and neuroendocrine analyses of plasma, platelet, urine, cerebrospinal fluid and brain samples using high performance liquid chromatographic (HPLC) methods and radiometric procedures. The methods are applied to studies of the neurobiology of autism, ADHD, Tourette's syndrome and adult neuropsychiatric conditions, and to investigations of the basic neurochemistry and psychopharmacology of serotonin. Recent studies in these areas are briefly described below.

In a large Dutch collaborative study, we have demonstrated bimodality distribution of platelet serotonin in autism. Follow-up proteomic studies are attempting to identify disorder- and subgroup-specific alterations of potential etiological significance. Postmortem brain studies of monoamine and amino acid neurotransmitter-related analytes and receptors in autism are ongoing. Possible neurochemical (catecholamines) and neuroendocrine (prolactin, leptin, cortisol) predictors and correlates of treatment of autism with the atypical neuroleptic risperidone, the selective serotonin reuptake inhibitor (SSRI) citalopram, and the stimulant and noradrenergic agents methylphenidate and guanfacine are being examined in collaborative studies multi-center studies coordinated by Dr. Lawrence Scahill of the Yale Child Study Center. In collaboration with Dr. Sylvie Tordjman of the University of Rennes, we are examining pineal function and sleep problems in autism, as well as investigating the relationship of b -endorphin, pain reactivity and self-injurious behavior in autism.

Collaborative studies (with Dr. J. D. Higley, NIAAA Primate Center Poolesville, Maryland) have examined the effects of the SSRI sertraline on central and peripheral serotonin. Additional studies examining the genetic, environmental, and pharmacological effects on serotonin levels in cisternal cerebrospinal fluid are planned, as are studies examining the neurobiological basis of anxiety-related behaviors. Ongoing studies with Dr. J. Winslow of the Poolesville facility are examining long-term behavioral and neurobiological effects of chronic SSRI exposure in young rhesus. Collaborative studies of self-injurious behavior in rhesus monkeys, as well as studies of social development in chimpanzees, are ongoing with Dr. B. Fontenot of the University of Louisiana New Iberia Research Center ( Lafayette, LA).

A series of collaborative human studies examine hypothalamic-pituitary-adrenal (HPA) axis functioning in ADHD, Tourette's PTSD, smoking behavior, depression and trauma.
