"...stroke syndromes are collections of signs and symptoms resulting from Strokes in different regions of the brain or central nervous system in this video we will cover the stroke syndromes associated with Strokes in of the middle cerebral artery IT supplies in most of the temporal lobe the anterolateral frontal lobe and the parietal lobe the middle cerebral artery comes off the internal carotid and is divided into segments the segments are the M1 or the horizontal segment which is the most proximal part and gives off a lenticular striate a tree which are deeper penetrating arteries that Supply the basal ganglia and surrounding region the M2 segment known as the Sylvian segment is next which typically includes a bifurcation into the superior and inferior segments em three segments a cortical supplying the cortex our first syndrome results from a stroke affecting the middle cerebral artery Superior division which normally supplies the lateral frontal lobe I'm the superior parietal lobes in this syndrome findings include contralateral weakness of the upper Limbs and the lower Limbs and a weakness of the contralateral lower face with a greater effect seen on the face and the Upper Limb rather than the lower limb this is because of the motor homunculus where we see that the areas of the cortex responsible for the legs are supplied more so by the anterior and so a less affected in Middle cerebral artery Strokes also remember that it is the lower part of the face that is affected because this only receives unilateral from the facial nerve while the upper two-thirds receives bilateral Innovation there is also often a Hemi sensory loss on the contralateral side that may affect the face or leg if the stroke involves the dominant hemisphere which is usually the left side then an expressive Aphasia it may be seen as Broca's area is found on the dominant side and is responsible for the production of speech if the stroke is on the non-dominant side then we see a contralateral any neglect where the patient may be unaware or unresponsive to stimulate on one side which may include not being able to recognize their own limbs next we have the middle cerebral artery inferior division..."
