[The final state of cerebral haemodynamics in elderly and senile age patients which died from various causes].
The state of cerebral haemodynamics in 62 elderly patients was analysed 2-4 days before death because of various causes: cardiovascular, cerebrovascular, malignant tumours and others. Cerebral haemodynamics was investigated with the help of dopplerographyc of pre-cerebral and cerebral arteries. Moreover, the medical data of all died patients and their blood vessels were investigated with the help of pathomorphological and morphometrical methods. It was discovered that the final state of cerebral haemodynamics depends on not only cerebrovascular pathology, but on some others backgrounding and accompanying diseases. The downfall of the cerebrovascular reserve is most dangerous. That downfall of the cerebrovascular reserve in combination with atherosclerotic stenosis, ischemia of brain and heart result in non-coordination of the activity in all three contours of auto-regulation of the cerebral haemodynamics: myogenic, metabolic, neurogenic. The given situation promotes a negative outcome of cerebrovascular pathology and other diseases. Investigation and correction of the cerebral haemodynamics in elderly patients are necessary irrespective of a clinical variant of the leading pathological process.
