Each of the five classical<unk>  syndromes has a relatively distinct symptom complex. Symptoms may occur suddenly, progressively, or in a fluctuating (e.g., the capsular warning syndrome) manner. Occasionally, cortical infarcts and intracranial hemorrhages can mimic<unk>  infarcts, but true cortical signs (aphasia, visuospatial neglect, gaze deviation, and visual field defects) are always absent in<unk> s. The classic syndromes are as follows: Name Location of infarct Presentation Pure motor<unk> /hemiparesis (most common<unk>  syndrome: 33–50%) posterior limb of the internal capsule, basilar part of pons, corona radiata It is marked by hemiparesis or hemiplegia that typically affects the face, arm, or leg of the side of the body opposite the location of the infarct. Dysarthria, dysphagia, and transient sensory symptoms may also be present. Ataxic hemiparesis (second most frequent<unk>  syndrome) posterior limb of the internal capsule, basilar part of pons, and corona radiata, red nucleus, lentiform nucleus, SCA infarcts, ACA infarcts It displays a combination of cerebellar and motor symptoms, including weakness and clumsiness, on the ipsilateral side of the body. It usually affects the leg more than it does the arm; hence, it is known also as homolateral ataxia and crural paresis. The onset of symptoms is often over hours or days. Dysarthria/clumsy hand (sometimes considered a variant of ataxic hemiparesis, but usually still is classified as a separate<unk>  syndrome) basilar part of pons, anterior limb or genu of internal capsule, corona radiata, basal ganglia, thalamus, cerebral peduncle The main symptoms are dysarthria and clumsiness (i.e., weakness) of the hand, which often are most prominent when the patient is writing; but dysarthia or involuntary movement can also be seen in legs. Pure sensory<unk>  contralateral thalamus (VPL), internal capsule, corona radiata, midbrain Marked by numbness (loss of sensation) on one side of the body; can later develop tingling, pain, burning, or another unpleasant sensation on one side of the body. Mixed sensorimotor<unk>  thalamus and adjacent posterior internal capsule, lateral pons This<unk>  syndrome involves hemiparesis or hemiplegia (weakness) with sensory impairment in the contralateral side.
