Volumetric MRI Assessment of Brain and Spinal Cord in Finnish Twins Discordant for Multiple Sclerosis
Abstract
Material and Methods. A co-twin control method was used to evaluate whether the brain and spinal cord volumes differ between twins with multiple sclerosis and their co-twins. Nineteen twin pairs were studied neurologically, and the volumes of T1, T2, FLAIR, and gadolinium-enhanced lesions and those of the brain and the spinal cord were obtained by magnetic resonance imaging. Results. Significant differences in the brain (P=0.064) or spinal cord (P=0.648) volumes were not detected. Four of the 7 monozygotic and 5 of the 12 dizygotic co-twins had focal brain white matter lesions, but none fulfilled the magnetic resonance imaging criteria of Barkhof. Spinal cord lesions were not seen in any of the co-twins.
Conclusions. The absence of a significant difference in the brain or spinal cord volume between the twins with multiple sclerosis and their co-twins supports the recent observation of brain size and the development of brain atrophy being highly heritable.
