"Occasionally, it may be difficult to differentiate a cortical stroke, due to either cortical infarct or intracranial haemorrhage, from a lacunar stroke syndrome. It is important to recall that unlike cortical strokes, patients with lacunar infarcts and associated lacunar stroke syndromes will not have cortical signs. Additionally, what may initially appear to be a lacunar stroke syndrome, may actually be a 'warning sign' of a larger deep territory infarction of MCA, PCA, or basilar artery territories."

"in the acute phase, patients with striatocapsular infarcts may exhibit both cortical (e.g. aphasia, sensory neglect or extinction, apraxia) and subcortical (eg. hemiparesis, dysarthria) signs, despite the cortex not being directly involved in the infarction"

"Each of the five classical lacunar syndromes has a relatively distinct symptom complex. Symptoms may occur suddenly, progressively, or in a fluctuating manner (e.g. the capsular warning syndrome, see transient ischaemic attack)."
"Unlike cortical strokes, patients with lacunar stroke syndromes do not exhibit any cortical signs such as aphasia, agnosia, sensory neglect or extinction, apraxia, visual field defects, or cortical sensory loss (e.g. agraphaesthesia, loss of two-point discrimination, loss of joint position sense, astereognosis)."

"This is the most common (33-50%) lacunar syndrome and usually occurs with infarction of the posterior limb of the internal capsule, which carries the descending corticospinal and corticobulbar tracts, or the basis pontis. It is characterised by contralateral hemiparesis that typically affects the face, arm and leg in approximately equal measure, usually in a pyramidal pattern."
"This syndrome is due to an infarct of the ventral posterolateral (VPL) nucleus of the thalamus. It is characterised by contralateral numbness of the face, arm and leg."
"The cheiro-oral-pedal syndrome is often a limited variant of this lacunar stroke syndrome, resulting in contralateral numbness of the corner of the mouth, hand and foot 7."
"This lacunar syndrome is typically due to infarction of the thalamus and adjacent posterior limb of the internal capsule. It is characterised by contralateral hemiparesis and sensory impairment of the face, arm and leg."
"This is the second most common lacunar syndrome and usually occurs with infarction of the posterior limb of the internal capsule, basis pontis, or corona radiata. It displays a combination of cerebellar and pyramidal hemiparesis on the contralateral side of the body. It usually affects the foot and leg more than it does the hand and arm; hence, it is known also as 'homolateral ataxia and crural paresis'."
