Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T-lymphocytes, and smooth muscle cells. The plaque that builds up can lead to further complications such as stroke, as the plaque disrupts blood flow within the intracranial arterioles. This causes the downstream sections of the brain that would normally be supplied by the blocked artery to suffer from ischemia. Diagnosis of the disease is normally done through imaging technology such as angiograms or magnetic resonance imaging. The risk of cerebral atherosclerosis and its associated diseases appears to increase with increasing age;  however there are numerous factors that can be controlled in attempt to lessen risk. Diagnosis
Diagnostic methods include:

AngiogramDue to positive remodeling the plaque build-up shown on angiogram may appear further downstream on the x-ray where the luminal diameter would look normal even though there is severe narrowing at the real site. Because angiograms require x-rays to be visualized the number of times an individual can have it done over a year is limited by the guidelines for the amount of radiation they can be exposed to in a one-year period. Magnetic resonance imaging (MRI)Magnetic resonance imaging has the ability to quantify the plaque anatomy and composition.
Infantilism may refer to:

In psychologyParaphilic infantilism, a paraphilia involving the desire to wear diapers and/or fantasies of a return to infancy
Psychosexual infantilism, a concept in psychosexual development introduced by Sigmund Freud
In a more general sense and in colloquial expressions – childlike behavior in adults, particularly lack of judgement and poor ability to make conclusions based on logical reasoning as well as actions driven more by immediate impressions and impulses rather than by rationale. Depending on degree of expression can range from mental disorder, to behavioral disorder or simply psychological makeup and personality trait of otherwise healthy person.In medicineInfantilism (physiological disorder) obsolete use of the term for some developmental disorders and disabilities
Infantilism, also known as infantile speech, a speech disorder in which early speech stages persist beyond the age they are normally expected to fade
Hypothalamic infantilism-obesity, or sexual infantilism, synonyms for adiposogenital dystrophy
