Choose two answers

Correct Answer : C,D
A. Oral anticoagulation is a treatment to prevent clots and reduce the risk of ischemic stroke, not a mechanism that causes a clot to form.
B. Anoxic encephalopathy is brain damage due to a lack of oxygen, which can be a result of stroke but is not a cause of thrombus formation.
C. Carotid stenosis or the narrowing of the carotid arteries, can lead to the formation of clots that may travel to the brain and cause an ischemic stroke.
D. Atrial fibrillation is a heart rhythm disorder that can lead to the formation of blood clots in the heart. These clots can then travel to the brain and cause an ischemic stroke.
E. Glutamate toxicity refers to neuronal damage caused by excessive glutamate but is not a mechanism that leads to clot formation or ischemic stroke.

B. Osteomalacia involves bone softening due to vitamin D deficiency and does not present with joint nodes or the type of stiffness described.
