[Changes in cerebral hemodynamics in chronic users of "PACO" and cocaine: case-control study]. / Cambios en la hemodinamia cerebral en consumidores crónicos de paco y cocaína: estudio de casos y controles.

OBJECTIVE: To assess if there are changes in brain hemodynamics evaluated by means of transcranial doppler's flow velocity, pulsatile index and cerebral perfusion pressure, between cocaine chronic abusers and healthy volunteers. METHOD: Prospective, case and control, observational study. Sex, age, user history, vital signs and transcranial doppler findings.Statistical analysis was performed by means of normality test, Wilcoxon's test for non parametric samples and T Student test. RESULTS: Fifty-three abusers and 35 healthy volunteers were studied. Statistical differences were found for a diminish in age(p=0.008) and cerebral perfusion pressure in all cerebral arteries (p
