Document Summary
Limbic system: primitive brain, involved in emotions, motivations, survival . Anterior cerebral: aphasia, memory and behavioral issues, lower extremity weakness. Middle cerebral: homonymous hemianopsia part of the visual eld is obscured in each eye. Posterior cerebral: loss of muscle tone in face and upper extremities, not able to recognize common object, pain syndrome. Arteriovenous malformation (avm) people sometimes they don"t even know they have them so they can cause a lot of damage if not caught early enough. Manifestations similar to stroke but they resolve within 24-48hours. It is a sign that they need to be seen because they are at risk of major strokes. Left side motor and sensory issues (you may not have both, it depends on where in the brain the issues are) Disinhibition emotions don"t match the situation (they might laugh at something that is really sad). Language issues (aphasia) most likely the stroke is in the temporal lobe. Inability to grasp meaning of spoken words.
