- Diffusion Measures Indicate Fight Exposure–Related Damage to Cerebral White Matter in Boxers and Mixed Martial Arts Fighters
Boxers and mixed martial arts athletes underwent brain DTI and the results were correlated with number of fights, knockouts, age, weight, and years of education. Total knockouts in boxers increased diffusivity in the corpus callosum, cingulate, pericalcarine, precuneus, and amygdala, while in martial arts athletes only the posterior cingulate was abnormal. Thus, fight exposure but not the number of fights can be used to predict microstructural brain damage.
- Utility of Proton MR Spectroscopy for Differentiating Typical and Atypical Primary Central Nervous System Lymphomas from Tumefactive Demyelinating Lesions
The utility of MRS in differentiating lymphoma from tumefactive demyelination was assessed in 44 patients with the former and 21 with the latter. A Cho/Cr over 2.58 and a high lipid/lactate peak were more common in lymphoma, therefore MRS may help in differentiating these 2 entities.
- Prevalence of Radiologically Isolated Syndrome and White Matter Signal Abnormalities in Healthy Relatives of Patients with Multiple Sclerosis
Healthy individuals who either had no relatives with multiple sclerosis or had a family history of it were studied and evaluated according the Okuda and Swanton criteria for radiologically isolated syndrome. These investigators found that the frequency of white matter signal abnormalities and radiologically isolated syndrome were higher in the healthy relatives of patients with multiple sclerosis compared with nonfamilial healthy control subjects. In healthy relatives of patients with MS, smoking and obesity also contributed to the presence of white matter lesions.
