Cerebral infarction (Stroke)
Can a cerebral infarction be cured?
Stroke is the most common cerebrovascular disease. It occurs when the arteries supplying blood to the brain become blocked, leading to ischemic necrosis of the brain tissue in that region. This results in a series of neurological deficits. Theoretically, once a stroke has occurred, it cannot be completely cured because brain cells are non-regenerative. Once they die, they cannot be revived, and the function of the neurons in that area is completely lost. However, the significance of acute phase treatment lies in the rescue of the ischemic penumbra. The function of these cells can be restored after treatment, and thereafter, they may compensate for the function of the central necrotic area. Thus, patients who receive treatment may regain some neurological functions. Another condition is that the patient must be brought to the hospital within 4.5 hours of the onset of symptoms. If there are no clear contraindications, RT-PA intravenous thrombolytic treatment can be administered. The success rate of this thrombolysis is relatively high, and about 30% of patients may be fully cured without any sequelae.
Precursors to cerebral infarction
For patients with cerebral infarction, before the onset of the illness, they often lack specific prodromal symptoms. Some patients may experience mild headaches, dizziness, nausea, and a clear feeling of discomfort. Additionally, some patients might experience numbness in the legs and involuntary twitching of facial muscles before the onset. Subsequently, some patients may also start to have drooping of the corner of the mouth to one side, drooling, slurred speech, and distinct articulation disorders. When these clinical presentations occur, it is necessary to be vigilant and seek timely medical attention at a local hospital. A cranial CT or MRI should be performed to confirm the diagnosis.
