Ipsilateral atrophy of the mammillary body and fornix after thalamic stroke: evaluation by MRI.

CONCLUSION: Damage to the anterior thalamic nucleus and/or MTT caused TND in the ipsilateral MB and/or Fx resulted in atrophy and asymmetry in less than half of patients studied, mostly within three years. PMID: 30909707 [PubMed - as supplied by publisher]

GravesAbstractAutomatic identification of brain lesions from magnetic resonance imaging (MRI) scans of stroke survivors would be a useful aid in patient diagnosis and treatment planning. It would also greatly facilitate the study of brain-behavior relationships by eliminating the laborious step of having a human expert manually segment the lesion on each brain scan. We propose a multi-modal multi-path convolutional neural network sys...

CONCLUSION: Symptomatic patients with ipsilateral carotid stenosis and silent brain ischaemia on pre-operative MR-DWI, more often showed pathological evidence of IPH compared with those without ischaemic lesions. This identifies carotid IPH as a marker for patients at risk of silent brain ischaemia and possibly for future stroke and other arterial disease complications. Such patients may be more likely to benefit from CEA than those without evidence of ipsilateral carotid IPH. PMID: 31631008 [PubMed - as supplied by publisher]

Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Conclusion: These findings indicate that TBI differentially affects the levels of sex-steroid hormones in men and women patients. Plasma levels of testosterone could be a good candidate blood marker to predict recovery from unconsciousness after sTBI for male patients. Introduction Traumatic brain injury (TBI) is a major cause of death and disability worldwide and is increasing in incidence (1). Patients with acute severe TBI (sTBI) often develop severe disorders of consciousness, i.e., coma, minimally conscious state or vegetative state. Although many patients may regain consciousness during the 1-month post-TBI p...

Conclusions: Our results demonstrate that the presence and extent of cSS are associated with reduced CSF ß-amyloid 42 levels. Further studies are needed to investigate the underlying mechanisms of this association. Introduction Cerebral amyloid angiopathy (CAA)—characterized by the deposition of ß-amyloid in the walls of leptomeningeal vessels—is a common cerebral small vessel disease and a major cause of intracerebral hemorrhage in the elderly (1–3). Furthermore, it has become evident that CAA is associated with cognitive impairment (4). Specifically, it has been shown that CAA patien...

Conclusion: We identified a novel non-sense mutation in MTHFR gene in a single Egyptian family with severe MTHFR deficiency. The present investigation is clinically important, as it adds to the growing list of MTHFR mutations, which might help in genetic counseling of families of affected children and proper genotype-phenotype correlation. Background Severe 5,10-Methylenetetrahydrofolate reductase (MTHFR; OMIM 236250) deficiency is a rare inborn error of metabolism and inherited in an autosomal recessive fashion. It is a very common disorder of folate metabolism and is clinically characterized with low plasma methion...

Conclusions: The present study showed that CST integrity (at 6 months after onset) in patients with chronic stroke was related to functional hand status. In addition, the mid-pons FA value was more predictive of functional restoration of the hand than the FN or FA value at the pontomedullary junction. These results may be useful in predicting the functional restoration of the hand and understanding the functional prognosis of stroke. Introduction Restoration of hand function is one of the most important goals for patients with stroke (1). Thus, techniques that aid in predicting restoration of hand function are also i...
