ABSTRACT
Age is associated with substantial macrostructural brain changes. While some recent CT scan studies have reported larger age affects in men than women, others find no sex differences, as brain morphometry is a potentially important tool in diagnosis and monitoring of age-related neurological diseases. A study was conducted on 147 Arakian healthy aged participants in the Department of Radiology, Valie asr Hospital, Arak city. Gray matter (GM), white matter (WM) and CSF was evaluated based on cranial CT scan images. Both males and females subjects were divided into four age groups. In this study, the subjects were 51.7% (76) male and 48.3% (71) female. Frequency of groups showed that the common types were in the 4th group of ages (65.1­80 years) with 44%. Although, in 147cases, all parameters were greater in male than female but no significant differences were seen. The significant differences between the two sexes were in length of cranium and width of cranium. There was significant difference between age groups in male and female. In male groups no significant difference was shown between them, but these were considered statistically significant in female groups in width of cranium (p=0.017), width of gray matter (p=0.008), length of cranium (p=0.052), length of white matter (P=0.024), distance of bicorn anterior (p=0.013), width of white matter in bicoronal Anterior (p=0.046), but in male age groups showed no statistically significant difference. We found changing in brain volume relationship with ageing in population, but this change in female is greater than male.
RESUMEN
La edad se asocia con cambios cerebrales sustanciales. Mientras que algunos estudios recientes han reportado que la edad afecta a hombres más que a mujeres, otros no encuentran diferencias sexuales. La morfometría cerebral es una herramienta potencialmente importante en el diagnóstico y seguimiento de enfermedades neurológicas relacionadas con la edad. Se realizó un estudio en 147 participantes sanos de edad avanzada en el Departamento de Radiología, Hospital de Valie asr, ciudad de Arak. La sustancia gris (SG), sustancia blanca (SB) y líquido cerebro-espina (LCR) fueron evaluados en base a imágenes craneales de escáner CT. Los sujetos, hombres y mujeres fueron divididos en cuatro grupos etarios. De los sujetos incluidos en el estudio, 51,7% (76) fueron hombres y 48,3% (71) mujeres. La frecuencia de los grupos mostró que los tipos más comunes estaban en el cuarto grupo etario de (65,1 a 80 años) con un 44%. En 147 casos todos los parámetros fueron mayores en hombres que en mujeres, sin embargo, no se observaron diferencias significativas. Entre los dos sexos las diferencias significativas estaban en longitud de cráneo y ancho del cráneo. No hubo diferencias significativas entre los grupos etarios. En los grupos de hombres, no se demostró ninguna diferencia significativa, pero éstos fueron considerados estadísticamente significativos en ancho de cráneo (p=0,017), ancho de cráneo de las mujeres, la sustancia gris (p=0,008), longitud del cráneo (p=0,052), longitud de la sustancia blanca (P=0,024), distancia anterior del bicornio (p=0,013) y el ancho de la sustancia blanca bicoronal anterior (p=0,046). Sin embargo en los grupos de edad de sexo masculino no se observaron diferencias estadísticamente significativas. Encontramos cambios en relación al volumen cerebral con el envejecimiento de la población; este cambio en el sexo femenino es mayor que el masculino.
