Objective We aimed to investigate the relationship between tortuosity of the extracranial internal carotid artery (ICA) or vertebral artery (VA) and vascular risk factors among residents of Asahikawa, northeast Japan. Methods We retrospectively surveyed participants of "brain dock" medical brain checkups, which involved magnetic resonance imaging and angiography. We measured the tortuosity of the ICA and VA, and evaluated vascular risk factors based on medical interviews, questionnaires, and medical records. ⋯ VA tortuosity (right and left) was significantly correlated with age (OR: 1.786, 95% CI: 1.250-2.550, p=0.001) and smoking history (OR: 2.140, 95% CI: 1.235-3.707, p=0.007), and was more pronounced in females than in males (OR: 1.864, 95% CI: 1.107-3.137, p=0.019). Conclusion ICA tortuosity was correlated with age, while VA tortuosity was correlated with age and smoking history. ICA and VA tortuosity were more pronounced in females than in males.

Objective In 2022, Wenning et al. proposed the Movement Disorder Society Criteria (MDS criteria) for the Diagnosis of Multiple System Atrophy (MSA). These criteria were expected to provide useful alternatives to the second consensus statement. We examined trends in these diagnostic criteria. ⋯ At the time of diagnosis, the classifications were as follows: clinically established (n=45; 66.2%); clinically probable (n=12; 17.6%); possible prodromal (n=4; 5.9%); and negative (n=7; 10.3%). At the final evaluation, the classifications were as follows: clinically established (n=52; 76.5%); clinically probable (n=9; 13.2%); possible prodromal (n=2; 2.9%); and negative (n=5; 7.4%). Conclusion We were able to clarify the changes in the criteria values and transition of patients due to the clarification of imaging and supportive findings in the MDS criteria.
