In the early stage of cerebral ischemic foci, patients usually have no obvious symptoms. As the disease progresses, symptoms such as headache, dizziness, and in severe cases, slurred speech, mobility, blurred consciousness, hemiparesis, memory loss, etc. may occur. Cerebral ischemic foci refer to foci formed when blood vessels in the brain are blocked and blood flow cannot be normalized, resulting in necrosis of local brain cells due to lack of oxygen and ischemia. Due to individual differences, the actual symptoms of patients may vary. Generally speaking, most patients have no obvious symptoms at the beginning of the disease, and only a few will have headache and dizziness. As the disease progresses, the symptoms of headache and dizziness will become more and more obvious, and one side of the limbs may have impaired mobility, such as the lower limbs can not walk flexibly, the hands can not hold objects, and there will also be slurred speech, crooked corners of the mouth, urinary and fecal incontinence, hemiplegia, memory loss, and fuzzy consciousness and other symptoms. Patients with cerebral ischemic foci need to be actively treated under the guidance of professional doctors.
