Abiant Selected to Present at 2009 ADNI Investigators Meeting

Deerfield, ILLINOIS - - April 26, 2009 - - Work co-authored by members of Abiant and the New York
University School of Medicine was presented on April 26 at the 2009 Alzheimer's Disease
Neuroimaging Initiative (ADNI) Investigators Meeting in Seattle, Washington.  The presentation, titled
"Regional Cerebral Glucose Metabolism at Baseline Predicts Symptom Onset in Normal ADNI
Subjects and Correlates to Disease Progression", focused on the results of analyses performed
using the neuroimaging scans in 250 patients in the ADNI database.

The results of this work showed that glucose metabolism levels declines in select regions of the
brain as subjects decline from Normal to Mild Cognitive Impairment stages and later Alzheimers
Disease.  Since glucose metabolism is a primary source of energy for the brain, measurement of
glucose utilization in various brain regions using positron emission tomography (PET) imaging
provides a powerful way to "see", or measure, where activity in the brain is declining. One of the
earliest regions of decline is the hippocampus, a structure involved in encoding new memories.   
Even in Normal subjects, decreased glucose metabolism activity can be seen well before the
subjects show symptoms.

ADNI Investigators Meeting 2009 Abstract.  

ADNI is a $60 million, 5-year public-private partnership to test whether serial magnetic resonance
imaging (MRI), positron emission tomography (PET), other biological markers, and clinical and
neuropsychological assessment can be combined to measure the progression of mild cognitive
impairment (MCI) and early Alzheimer’s disease (AD).  Additional information can be found at the
ADNI website.
