Developing Neurobehavioral Biomarkers for Targeted Treatment in Fragile X from Human and Animal Studies

Lecturers: Robert F. Berman, Ph.D., Susan Rivera, Ph.D., & Tony J. Simon, Ph.D.

Affiliation: UC Davis MIND Institute

Date: January 29, 2010

Length: 1:29:32

Synopsis: An overview of integrated neuroscience research efforts to study Fragile X-associated tremor ataxia (FXTAS). Specifically, the presentation will describe how studies in human FXTAS patients and basic science findings in transgenic mouse models of FXTAS have been integrated so that each informs the other to accelerate the pace of scientific discovery.

A New Age of Treatment for Fragile X Syndrome

Date: August 7, 2009

Length: 58:05

Summary: Neurobiological abnormalities in Fragile X Syndrome, review of targeted treatments available and the mechanisms by which they work, with preliminary data regarding minocycline, fenobam, and R-baclofen.

New Targeted Treatments for Fragile-X Syndrome

Length: 1:20:21

Fragile X: A Family Affair

Presenters: Paul Hagerman, M.D.,Ph.D. & Randi Hagerman, M.D.

Affiliation: UC Davis MIND Institute

Date: January 17, 2008

Length: 1:41:28

Synopsis: It's hard to imagine, but defects in a single gene can cause mental impairment in children, premature ovarian failure in women and dementia in older adults. That gene -- the fragile X gene -- is the research focus of two MIND Institute investigators who are leading the way in discovering the molecular foundations of and new treatments for the broad spectrum of fragile X-related disorders. Hear more about what their work has revealed about the causes and outcomes of fragile X syndrome, their plans for new treatment trials and the benefits of their discoveries for understanding neurodevelopmental and neurodegenerative disorders.

Three Disorders, One Explanation? The Case of Cognitive Impairments in Fragile X Syndrome, Turner and Chromosome 22q11.2 Deletion Syndrome

Presenter: Tony Simon, Ph.D.

Affiliation: UC Davis MIND Institute

Date: Oct 16, 2008

Length: 1:07:28

Synopsis: Chromosome 22q11.2 deletion, Turner, and fragile X syndromes are different genetic disorders producing weakness in visuospatial, visuomotor and numerical cognition. 7 to 14 year old children with these disorders were studied to see if a common mechanism might be at work. Dr. Simon will present results from experimental cognitive and brain imaging studies that explain how children with these disorders think about space, time and number and suggest designs for therapeutic interventions.

What We Learn About Autism from Studying Fragile X Syndrome

Presenters: David Hessl, Ph.D., Lisa Cordeiro

Affiliation: UC Davis MIND Institute

Date: Jan 22, 2009

Length: 54:22

Synopsis: Individuals with autism and fragile X syndrome share many symptoms and there may be common neurobiological abnormalities underlying these symptoms. Dr. Hessl will share recent findings from his laboratory and others focusing on this topic and discuss implications that the overlapping features may have for the treatment of both conditions.
