Determinación de intersecciones probabilísticas relacionadas con daño cerebral adquirido a partir de la determinación de probabilidades a priori y a posteriori.

Background: The acquired brain damage is a common neurological disorder.

Objective: Determine the probabilistic intersections of variables related to acquired brain damage from the determination of a priori and a posteriori probabilities.

Method: Analytical retrospective study. A descriptive analysis was carried out, confidence intervals were calculated to obtain the mean and the proportion with α = 0.05 considering the age of the patient and the diagnosis. An analysis of probabilistic intersection, a priori and a posteriori probability was performed considering diagnosis, sex and age decade; finally, chi squared was calculated.

Results: 736 patients were analyzed. The most frequent diagnosis was language disorder. The patients diagnosed with memory disorder were the youngest and those diagnosed with degenerative cognitive disorder the oldest. The probability that a patient with sequelae due to acquired brain damage arrives at the hospital, at the language pathology service, to be diagnosed with a language disorder and that this patient is also a man is 29.06%.

Conclusions: The high prevalence of short and long-term disability generated by acquired brain damage highlights the importance of an early and timely detection and diagnosis so that it favors prompt and efficient specialized care.
