Redlich used the term 'miliary sclerosis' to describe plaques because he thought they resembled millet seeds, and he was the first to refer to the lesions as 'plaques'. [ 4 ] In the early 20th century, Oskar Fischer noted their similarity to actinomyces 'Drusen' (geode-like lesions), leading him to call the degenerative process 'drusige Nekrose ...
The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates. It is considered part of the limbic system. [2]
[162] [163] [164] One study estimated that as many as 0.4% of cancers in the United States resulted from CT scans, and that this may have increased to as much as 1.5 to 2% based on the rate of CT use in 2007. [148] Others dispute this estimate, [165] as there is no consensus that the low levels of radiation used in CT scans cause damage. Lower ...
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
In the DCCT (Diabetes Control and Complications Trial, 1995) study, the annual incidence of neuropathy was 2% per year but dropped to 0.56% with intensive treatment of Type 1 diabetics. The progression of neuropathy is dependent on the degree of glycemic control in both Type 1 and Type 2 diabetes.
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
Lesions to V1, for example, can cause blindsight in different areas of the brain depending on the size of the lesion and location relative to the calcarine fissure. [12] Lesions to V4 can cause color-blindness, [13] and bilateral lesions to MT/V5 can cause the loss of the ability to perceive motion.
Unspecific cortical lesion on CT scan is confirmed cystic and benign with contrast-enhanced renal ultrasonography. Most renal cell carcinomas are now found incidentally. [19] Tumors less than 3 cm in diameter less frequently have aggressive histology. [20] A CT scan is the first choice
