Science and Service: Opening Pathways to Better Mental Health Complexities of Co-occurring Conditions Meeting Richard K. Nakamura, Ph.D. Deputy Director National Institute of Mental Health
NIMH Mission Reduce the burden of mental and behavioral disorders through research on mind, brain and behavior
How do we do this? NIMH budget is over $1.3 billion 7th Largest Institute of the NIH Most goes into 2000 research grants around the country based on expert review that funds less than 1/3 of applications.
The Burden of Mental Illness is Enormous
the World Health Organization Disability Adjusted Life Year World Bank and the World Health Organization Global Burden of Disease To measure both premature death and disability, a single measure was developed: Disability Adjusted Life Year DALY One DALY is one lost year of healthy life.

The Brain Changes We now understand that our genes specify a general plan with many options. Our brain changes its physical structure through behavior and interactions with the environment
A Revolution Our new understanding of the brain integrates: nature and nurture mind and brain genes and the environment
Neurogenesis in the Adult Human II Fig. I: Newly generated cells can be detected in the adult human brain in patients previously treated with BrdU. (a) The hippocampal region of the adult human brain immunoperoxidase-stained for the neuronal marker NeuN. (b) The hippocampal dentate gyrus granule cell layer (GCL) visualized with immunoperoxidase staining for NeuN. (c) Differential interference contrast photomicrograph showing BrdU-labeled nuclei (arrows) in the dentate granule cell layer (GCL). (d) Differential interference contrast photomicrograph showing a BrdU-labeled nucleus (arrow) in the human dentate GCL. BrdU-positive nuclei have a rounded appearance and resemble the chromatin structure of mature granule cells and are found within the granule cell layer. (e) Differential interference contrast photomicrograph showing BrdU-positive cells (arrows) adjacent to the ependymal lining in the subventricular zone of the human caudate nucleus. Cells with elongated nuclei resembling migrating cells are in the rat subventricular zone (SVZ). (f) Differential interference contrast photomicrograph showing BrdU-positive cells (arrows) with round to elongated nuclei in the subventricular zone of the human caudate nucleus. All scale bars represent 50 microns. Fig. II: Quantitation of newly generated cells in the adult human hippocampus. The density of BrdU immunoperoxidase-stained cells in the subgranular zone (SGC) (a) and the granule cell layer (GCL) (b) and the hilus (c) was determined in 5 to 7 sections per patient (mean number of BrdU-positive cells per mm3 sample volume s.e.m.) The corresponding patient's age at the time of death and interval as BrdU infusion are given for each BrdU-treated patient (n = 5). Methods: Postmortem tissue from the hippocampus and the subventricular zone of caudate nucleus was obtained from cancer patients (n = 5) who received one intravenous infusion (250 mg; 2.5 mg/ml, 100 ml) of bromodeoxyuridine (BrdU) for diagnostic purposes. One patient diagnosed with a similar type and location of cancer, but without BrdU treatment, was included as a control.

Physical Activity & Neurogenesis Running significantly increased cell proliferation/neurogenesis in the dentate gyrus of mice. (a) Total number of BrdU-positive cells per dentate gyrus one day after the last BrdU injection, to estimate ongoing proliferation. Significantly more cells were labeled in the runners as compared to the other groups. * p < 0.02. Enrichment and running significantly increased the survival of newborn cells. (b) Total number of BrdU-positive cells per dentate gyrus four weeks after the last BrdU injection, to estimate survival of labeled cells.
