AbstractAlthough considerable research has been devoted to cognitive functions deteriorating due to diseases of cardiovascular system, rather less attention has been paid to their theoretical background. Progressive vascular disorders as hypertension, atherosclerosis and carotid artery stenosis generate most of all pathological changes in the white matter, that cause specific cognitive disorder: disconnection syndromes, and disturbances in the dynamic aspect of information processing. These features made neuropsychological disorders secondary to cardiovascular diseases different than the effects of cerebral cortex damage, which may be interpreted modularly.

Several magnetic resonance (MR) techniques have proved to be sensitive enough to detect the subtle pathological changes that post-mortem studies showed to occur in the normal-appearing white matter (NAWM) from patients with multiple sclerosis (MS). Although these abnormalities can be detected in other neurological conditions, they seem to be more frequent and diffuse in MS. However, the contribution of NAWM changes to the diagnosis is still unclear. Their nature is also unknown and perhaps differs in different phases and clinical manifestations of the disease. Nevertheless, the extent and severity of NAWM damage seems to be relevant in causing disability and influencing the clinical evolution in MS patients. This review will summarize the present knowledge about MR-detected NAWM changes in MS and their relevance to the diagnosis and the understanding of disease evolution.

Background: Early pathological changes in white matter microstructure can be studied using the diffusion tensor imaging (DTI). It is not only important to study these subtle pathological changes leading to cognitive decline, but also to ascertain how an intervention would impact the white matter microstructure and cognition in persons at-risk of dementia. Objectives: To study the impact of a multidomain lifestyle intervention on white matter and cognitive changes during the 2-year Finnish Geriatric Intervention Study to prevent Cognitive Impairment and Disability (FINGER), a randomized controlled trial in at-risk older individuals (age 60–77 years) from the general population. Methods: This exploratory study consisted of a subsample of 60 FINGER participants. Participants were randomized to either a multidomain intervention (diet, exercise, cognitive training, and vascular risk management, n = 34) or control group (general health advice, n = 26). All underwent baseline and 2-year brain DTI. Changes in fractional anisotropy (FA), diffusivity along domain (F1) and non-domain (F2) diffusion orientations, mean diffusivity (MD), axial diffusivity (AxD), radial diffusivity (RD), and their correlations with cognitive changes during the 2-year multidomain intervention were analyzed. Results: FA decreased, and cognition improved more in the intervention group compared to the control group (p < 0.05), with no significant intergroup differences for changes in F1, F2, MD, AxD, or RD. The cognitive changes were significantly positively related to FA change, and negatively related to RD change in the control group, but not in the intervention group. Conclusion: The 2-year multidomain FINGER intervention may modulate white matter microstructural alterations.

✓ This study shows that spinal cord pathology secondary to acute trauma in monkeys evolves with stepwise sequential changes. The acute damage is more central than peripheral. Depending on the amount of trauma, the subacute damage may be limited to central gray necrosis or may progress or evolve to include the neighboring white matter. These pathological changes may be taking place even in the presence of clinical improvement.

ABSTRACT:Four patients presented with hemiballism-hemichorea as a clinical manifestation of white matter ischemia. These patients illustrate “positive” motor phenomena rather than limb weakness as a consequence of cerebral ischemia. In each patient, the involuntary movements disappeared following worsening of paresis. Subcortical white matter infarction in three patients and hemodynamic hypo-perfusion in the cerebral hemisphere contralateral to dyskinetic movements were possible causes. Neuroradiologically, none had pathological changes in the vicinity of the subthalamic nucleus. We presume from these observations that ischemia of the subcortical white matter, without involvement of the basal ganglia or the subthalamic nucleus, may cause hemiballism-hemichorea
