“…SAE's cognitive impairment often manifests early, although it is sneaky. When clinical discovery and diagnosis occur, the patient's cognitive impairment is often already severe [ 3 ]. The mechanism of the occurrence and development of cognitive impairment in subcortical arteriosclerotic encephalopathy is still unclear.…”

This paper discusses the imaging diagnostic features of arteriosclerotic encephalopathy and combines the spatial context information of local features to study the clinical imaging image copy detection algorithm. Moreover, this paper proposes a clinical imaging copy detection algorithm that combines the BOW model and spatial context embedding and a clinical imaging copy detection algorithm that combines the BOW model and global context verification. In addition, this paper applies the algorithm to the imaging diagnostic features of arteriosclerotic encephalopathy and sets up a controlled experiment to start research. The experimental research shows that the application of imaging diagnosis to the detection of subcortical arteriosclerotic encephalopathy has good clinical effects and rapid remission of patients’ symptoms. The effectiveness of this method can be verified by a large number of clinical practices in follow-up studies.

“…19 Arteriosclerosis is poorly documented in reptiles with only 2 cases reported in bearded dragons. 22,23 In those reports, arteriosclerosis was observed at the efferent cardiac vessels, but also in many other vessels and cerebral arterioles. In those cases, plaques composed of well-vascularized fibrous connective tissue were frequently overlain by a thick layer of fibrin and few erythrocytes.…”

This study describes the clinical, gross, and histologic findings in 17 cases of aneurysms in bearded dragons ( Pogona vitticeps). The clinical presentation ranged from incidental to sudden and unexpected death. The affected vasculature was predominantly arterial; however, based on the topographical locations of the lesions, gross structure, and drainage, some veins were likely involved. Magnetic resonance imaging and computerized tomography scans of 1 animal showed a large aneurysm of the internal carotid artery extending from near its aortic origin into the caudal head. Aneurysms were organized in 5 groups based on their anatomical locations: cephalic, cranial coelom (for all near the heart), caudal coelom (for the mesenteric vessels and descending aorta), limbs, and tail. The cranial coelomic region was the most prevalent location. Gross findings were large hematomas or red serosanguineous fluid filling the adjacent area, as most of the aneurysms (94%) were ruptured at the time of the study. The main histological findings were degenerative changes of the vessel walls characterized by moderate to severe disruption of the collagen and elastic fibers of the tunica media and adventitia (100%), followed by thickening of the intima with thrombi formation (54%) and dissecting hematoma of the vessel wall (47%). Vasculitis (29%), mineralization (6%), and lipid deposits (6%) in the vessel wall were observed occasionally. Based on these findings, the vascular dilations and ruptures observed in bearded dragons likely are associated with weakness of the vessel walls caused by degenerative changes in the intimal and medial tunics.
