Sequelae of closed craniocerebral trauma and the efficacy of piracetam in its treatment in adolescents.
The efficacy of piracetam in treating the sequelae of moderate and severe closed craniocerebral trauma (CCT) in adolescents was evaluated in studies of 42 patients aged 12-18 years who had suffered CCT 1.5-5 years prior to the study. Adolescents of the experimental group (20 individuals) received piracetam (Nootropil) at doses of 40-50 mg/kg (daily daily 1600-2400 mg) for one month; patients of group 2 (22 individuals) served as controls. Piracetam was found to have positive therapeutic effects on impairments to higher mental (memory, attention, executive) and motor (coordination) functions and on measures of the speeds of cognitive and motor operations.

The state of cerebral hemodynamics in conditions of prolonged adaptation to hypercapnic hypoxia.
Intermittent hypercapnic hypoxia was accompanied by increases in cerebral vascular resistance, decreases in the reactivity of cerebral vessels to hypercapnia, and increases in the collateral reserve and rate of autoregulation of brain blood flow. These changes were an important component of the mechanism increasing the tolerance of the brain to ischemia in response to training with hypercapnic hypoxia.
