Right parietal cerebral infarction is also a more serious condition that usually results in clinical incontinence and loss of use. In the absence of limb paralysis and ataxia, patients may still have a reduced ability to perform delicate and skilled movements, for example, the patient’s left hand is unable to complete the action of buttoning, and the patient may have conceptual disuse, asking the patient to touch his right ear with his left hand, which he cannot understand or complete. For example, the patient may not be able to brush his teeth or comb his hair. In addition, right parietal cerebral ridge occlusion may also cause somatoform disorder, which means that the patient may deny the existence of his left limb or think that the left limb is not his own.
