✓ The ability of a competitive N-methyl-D-aspartate (NMDA) receptor antagonist (D-CPP-ene) to reduce irreversible brain damage has been examined in a rodent model of acute subdural hematoma. Acute subdural hematoma was produced by the slow injection of 400 µl homologous blood into the subdural space overlying the parietal cortex in halothane-anesthetized rats. Brain damage was assessed histologically in sections at multiple coronal planes in animals sacrificed 4 hours after induction of the subdural hematoma. Pretreatment with D-CPP-ene (15 mg/kg) significantly reduced the volume of ischemic brain damage produced by the subdural hematoma from 62 ± 8 cu mm (mean ± standard error of the mean) in vehicle-treated control rats to 29 ± 7 cu mm in drug-treated animals. These data demonstrate the anti-ischemic efficacy of NMDA antagonists in an animal model of intracranial hemorrhage in which intracranial pressure is elevated, and suggest that excitotoxic mechanisms (which are susceptible to antagonism by D-CPP-ene) may play a role in the ischemic brain damage which is observed in patients who die after acute subdural hematoma.

Iodine is a micronutrient: the daily requirement is 100-200 mcg. The most obvious manifestation of iodine deficiency is endemic goiter. Iodine deficiency increases the frequency of congenital hypothyroidism and leads to irreversible brain damage in the fetus and newborn. In addition to pronounced forms of mental retardation, iodine deficiency causes a decrease in the intellectual potential of the entire population living in an area of iodine deficiency.

Variables which are of influence in establishing clear predictions of neuropsychological alterations from neuroradiological data (and vice versa) are documented and discussed. It is concluded that personality factors and the kind and locus of brain lesions are the most crucial determinants. The locus of the brain damage may have cumulative effects either when it is situated in a strategic place (usually within the white matter, affecting interneuronal communication) or when various types of lesions appear superimposed (combination of focal and diffuse lesions). Consequently, the consideration of the patient's personality background and of as many neuropsychological facts as possible may considerably increase the validity of outcome predictions. When static or dynamic neuroimaging fails to show abnormalities in spite of obvious psychological alterations, an intensive neuropsychological documentation may even replace neuroradiology.

We describe a simple, three-dimensional constructional test (the Box test), which reflects common daily-living activities, to be used for the assessment of constructional disability in elderly brain-lesioned patients. Subjects are required to put as many of 12 objects of varied shape and volume as they can into a box. To carry out the task successfully subjects have to arrange the items according to an efficient constructional strategy. We administered this test to 68 normal subjects and to 50 brain-damaged patients. Analysis indicated the Box test is easy and simple to administer and can be used without difficulty by elderly patients having focal brain damage. Performance correlated well with general intelligence and other bidimensional, conventional constructional tasks. Right or left brain lesions have a similar, significant detrimental effect on performance but probably through different mechanisms.
