The right basal ganglia region lacunar foci are generally referred to as lacunar cerebral infarcts, which may present with a variety of symptoms, such as purely motor mild hemiparesis, dysarthria, purely sensory stroke, and ataxic mild hemiparesis. 1. Pure motor hemiparesis: If the lesion is in the pons, internal capsule or radial crown, hemiparesis or ipsilateral limb and facial illustration may occur, but there is no sensory, speech or visual impairment. 2. Dysarthria: If the lesion is in the basal ganglia or the internal capsule, aphasia, dysphagia, contralateral facial paralysis, mild weakness of the hands, or inability to perform fine motor skills. 3. Purely sensory strokes: If the lesion is in the ventral posterior lateral nucleus of the thalamus, sensory deficits in one limb may occur. 4. Ataxic mild hemiparesis: If the lesion is in the subcortex, basal ganglia of the white matter or internal capsule, there will be mild ataxia of one limb. The above symptoms should be treated promptly and actively, and rehabilitation training should be carried out to alleviate the symptoms and avoid the after-effects.
