Introducción: el ataque transitorio de isquemia constituye una parte fundamental de la enfermedad cerebrovascular, en muchas ocasiones no bien diagnosticado por su corta duración, lo difícil de ver y sus variadas manifestaciones clínicas. Esta investigación se realizó con el propósito de caracterizar a los pacientes con ictus isquémico y previo ataque transitorio de isquemia, atendidos en el servicio de consulta externa no. 3 del Instituto de Neurología y Neurocirugía (INN) entre febrero de 2006 y noviembre de 2009. Métodos: se realizó un estudio observacional, descriptivo en 50 pacientes que, previo al ictus isquémico, habían presentado cuadros de ataques transitorios de isquemia. Se describieron las manifestaciones clínicas de presentación de estos, se analizaron los factores de riesgo, el territorio vascular afectado y el tiempo transcurrido entre el ataque transitorio de isquemia y el ictus isquémico. Resultados: en el 100 % de los pacientes, los ictus isquémicos dañaron el mismo territorio vascular afectado por los ataques transitorios de isquemia que le antecedieron. Conclusiones: quedó demostrada la importancia del ataque transitorio de isquemia como piedra angular fundamental en la enfermedad cerebrovascular. El infarto cerebral ocurrió con más frecuencia en los primeros meses secundarios al ataque transitorio de isquemia. La hipertensión arterial, los inadecuados hábitos de vida y la diabetes mellitus, constituyeron los principales factores de riesgo en la población estudiada.Introduction: transient ischemic attack constitutes a major part of cerebrovascular disease. In many cases it is not well diagnosed, due to its short duration, its many clinical manifestations and the difficulty to spot it. This study was conducted with the purpose of characterizing patients with ischemic stroke and a previous transient ischemic attack cared for at Outpatient Service No. 3 of the Institute of Neurology and Neurosurgery (INN) between February 2006 and November 2009. Methods: an observational descriptive study was conducted with 50 patients who had had a transient ischemic attack before they had their stroke. A description was made of the clinical manifestations at presentation, and an analysis was performed of the risk factors, the affected vascular territory, and the time elapsed between the transient ischemic attack and the ischemic stroke. Results: in 100 % of the patients the vascular territory affected by the ischemic stroke was the same as that affected by the preceding transient attacks. Conclusions: it was demonstrated that the transient ischemic attack is a fundamental component of cerebrovascular disease. Cerebral infarction was more frequent during the first months following the transient ischemic attack. Arterial hypertension, inadequate life styles and diabetes mellitus were the main risk factors in the population studied.

"The aim of this study is to determine differences in the performance of an attention-related task involving martial arts skills. 12 expertmartial arts athletes and 13 novices took part, performing the Test of Variables of Attention (Leark, Greenberg, Kindschi, Dupuy and Hughes, 2007).Using a non-parametric statistical permutation method, the test data for each variable, condition and segment of the test was analysed. Comparisons ofthe groups showed a trend toward a higher global Attention Deficit Hyperactivity Disorder (ADHD) score by the expert athletes as compared with thenovices. In order to find out each group’s performance during the test, a statistical intra-group analysis was performed. Generally, the results revealedmore consistent accuracy and response times by the experts than by the novice athletes. The results suggest that physical and mental training in themartial arts may increase the attention skills of sportsmen and women."
