What is the most common characteristic of anterior cerebral artery syndrome?
ACA infarct can present as contralateral hemiparesis with loss of sensibility in the foot and lower extremity, sometimes with urinary incontinence. This is due to the involvement of the medial paracentral gyrus.
Which symptom is most consistent with a thrombosis of the anterior cerebral artery?
Occlusions distal to this segment will result in more severe presentation of ACA syndrome. Contralateral hemiparesis and hemisensory loss of the lower extremity is the most common symptom associated with ACA syndrome.
What are the classic signs and symptoms of a stroke caused by blockage of the right middle cerebral artery?

What is frontal Encephalomalacia?
Encephalomalacia is the softening or loss of brain tissue after cerebral infarction, cerebral ischemia, infection, craniocerebral trauma, or other injury. The term is usually used during gross pathologic inspection to describe blurred cortical margins and decreased consistency of brain tissue after infarction.
What causes TLE?

What is the anterior cerebral artery?What is the anterior cerebral artery?
Being located in the anterior and medial aspects of the interhemispheric fissure, the anterior cerebral artery supplies a large portion of the medial cerebral hemispheric surfaces namely the corpus callosum, frontal, parietal, and cingulate cortex. Through the anterior communicating artery, it anastomoses with its contralateral counterpart.
What part of the brain does the anterior fossa accommodate?What part of the brain does the anterior fossa accommodate?
Each fossa accommodates a different part of the brain. The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain.
