The precursor of cerebral thrombosis in neurology is called transient ischemic attack (TIA). As the name suggests, this is a transient disease, mainly characterized by symptomatic speech impairment, facial droop, drooling, episodic dizziness, blurred vision, and episodic numbness and weakness of limbs. These symptoms are generally transient, usually lasting from several minutes to a few hours and can be completely relieved. The precursor of cerebral thrombosis is regarded as an emergency in neurology and must be treated promptly. Delayed treatment can possibly progress to cerebral infarction, severely affecting the patient's quality of life and physical health. In considering this disease, one must immediately rush to the hospital for appropriate treatment with antiplatelet drugs, lipid-regulating drugs to stabilize plaques, and treatments such as volume expansion and fluid supplementation.
