3H]2-(2-Benzofuranyl)-2-imidazoline, a highly selective radioligand for I2-imidazoline receptor binding sites. Studies in rabbit kidney membranes

The purpose of this study was to delineate significant differences among mild traumatic brain-injured and early onset mild dementia patients examined using the Wechsler Memory Scale-Revised subtests. In comparison to 12 mild traumatic brain-injured patients, 11 mild dementia patients scored significantly lower on Verbal Paired Associates I and II, Visual Reproduction I and II, and Visual Paired Associates I. Raw score summaries for the Wechsler Memory Scale-Revised indicated significantly lower scores on Verbal Memory, Visual Memory, and the over-all composite. General Memory for mild dementia patients in comparison to individuals who sustained a mild traumatic brain injury. Despite equivalent scores on Attention/Concentration, the dementia group did not show significantly lowered delay in memory recall by comparison with mild closed-head injured patients. The study recommends replication with much larger sample sizes to validate the results.
