Cavernous cerebral infarction usually has mild symptoms, single sign and better prognosis. Clinically, there is usually no headache, increased intracranial pressure and impaired consciousness. There are 5 common subtypes as follows: 1. Pure motor mild hemiparesis: the main surface is mild hemiparesis of the contralateral side and upper and lower limbs of roughly the same degree, without sensory impairment, visual impairment and cortical dysfunction (e.g., aphasia, etc.). Vertigo, tinnitus, nystagmus, diplopia and cerebellar ataxia are usually absent. 2. Pure sensory stroke: manifested as absence of eccentric sensation, which may be accompanied by sensory abnormalities, such as numbness, burning or heavy sensation, tingling, stiffness and so on. 3. Ataxic light hemiparesis: light hemiparesis on the contralateral side of the lesion with cerebellar ataxia, hemiparesis of the lower limbs is more obvious than that of the upper limbs (ankles), and the face is the lightest, which may be accompanied by vertebral fasciculus sign. 4. Dysarthria-hand clumsiness syndrome: the onset of the disease is sudden, with symptoms reaching a rapid peak, manifesting as dysarthria, dysphagia, central facial paralysis on the side opposite to the lesion, weakness of the hand on the side of the facial paralysis and clumsiness of the hand in fine motor movements, inaccurate finger-nose test, and mild balance disorders. 5. Sensory-motor stroke: the disease starts with hemiplegia, followed by mild hemiparesis. Clinical symptoms of lacunar cerebral infarction vary, so it is recommended to consult the hospital in time after the attack, so as to avoid the delay of the condition.
