Abstract
Cerebral circulation was investigated by the REG method in a group of thirty-four workers in whom lead poisoning had been proved by clinical and laboratory examinations. A control group consisted of twenty-four subjects of approximately the same age, with no previous occupational exposure to lead. The duration of the anacrotic phase was significantly longer in lead poisoned subjects. In addition, morphological alterations of REG waves in these subjects indicated a decreased distensibility and increased tonus of cerebral blood vessels, primarily arterioles. Seven subjects showed REG changes which reflected diffuse alterations of the cerebral artery. The authors consider that headache in subjects poisoned by lead is of vascular origin.
