Low Blood Pressure and Cerebral Infarction Symptoms

Low blood pressure cerebral infarction, clinically referred to as hypoperfusion cerebral infarction, often appears as bead-like lesions on CT or MRI scans. This type of infarction can affect both the anterior and posterior circulation systems of the brain. It typically occurs in the border zone between two major arterial supply areas, especially in the regions supplied by the middle and anterior cerebral arteries.

Common Symptoms of Hypoperfusion Cerebral Infarction

Patients may experience mild limb weakness, slight cognitive impairment, and dizziness. These symptoms often indicate reduced blood flow to critical areas of the brain. In some cases, confusion or difficulty concentrating may also be present, particularly in older adults.

Posterior Circulation Involvement

If the infarction affects the watershed area between the middle and posterior cerebral arteries, patients may develop symptoms such as vertigo, visual field defects, and hemianopia (loss of half the visual field). These individuals may also exhibit gait instability, walking with a tendency to lean to one side. Additionally, they may feel heaviness or weakness in their limbs, which can interfere with daily activities.

Treatment and Management Strategies

For hypoperfusion cerebral infarction caused by low blood pressure, it is recommended that patients increase their blood volume. In more severe cases, intravenous fluids or other forms of volume expansion therapy may be necessary. These interventions aim to restore adequate cerebral perfusion and prevent further neurological damage.

Alongside supportive care, medications such as antiplatelet agents and drugs that improve blood circulation should be administered. These treatments help prevent the formation of new blood clots and promote better blood flow to affected brain regions. Early intervention is crucial for minimizing long-term complications and improving patient outcomes.
