Research Abstract |
We measured the central benzodiazepine receptors (cBZRs) using positron emission tomography in patients with major cerebral artery disease and cerebral infarction. Neuronal damage manifested as a decrease in the cBZRs was found not only in the non-infarcted cerebral cortex, possibly through primary ischemia, but also in the thalamus, possibly through transneuronal degeneration. A decrease in the cBZRs in the cerebral cortex showed a statistically significant correlation with cognitive dysfunction but that in the thalamus did not.
