NIH-funded Study Defines Treatment Window for HIV-positive Children Infected at Birth

Press Release • March 07, 2012

HIV-positive children older than 1 year who were treated after showing moderate HIV-related symptoms did not experience greater cognitive or behavior problems compared to peers treated when signs of their infection were still mild, according to a study funded by the National Institutes of Health.

Gene Regulator in Brain’s Executive Hub Tracked Across Lifespan – NIH study

Press Release • February 02, 2012

For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain’s executive hub. Among key findings of the study by National Institutes of Health scientists: genes implicated in schizophrenia and autism turn out to be members of a select club of genes in which regulatory activity peaks during an environmentally-sensitive critical period in development.

Ethnic Disparities Persist in Depression Diagnosis and Treatment Among Older Americans

Science Update • January 26, 2012

Older racial and ethnic minorities living in the community are less likely to be diagnosed with depression than their white counterparts, but are also less likely to get treated, according to a recent NIMH-funded analysis published online ahead of print December 15, 2011, in the American Journal of Public Health.

The antipsychotic medication risperidone is more effective for initial treatment of mania in children diagnosed with bipolar disorder compared to other mood stabilizing medications, but it carries the potential for serious metabolic side effects, according to an NIMH-funded study published online ahead of print January 2, 2012, in the Archives of General Psychiatry.

Turning on Dormant Gene May Hold Key for Correcting a Neurodevelopmental Defect

Science Update • January 05, 2012

Scientists working in cell culture and in mice have been able to correct the loss of gene activity underlying a rare but severe developmental disorder by turning on a gene that is normally silenced in brain cells.
