WHAT IS ISCHEMIC STROKE?

There are generally three types of stroke. There is a rupture in the vessels of the brain in hemorrhagic stroke. It results in bleeding. Bleeding causes damage to the brain. Another type is transient ischemic stroke. In this stroke, blood flow reduces or stops temporarily.  The third type is ischemic stroke. In this stroke, there is a blockage in the brain's blood vessels. As a result, there is a lack of oxygen and essential nutrients in the brain tissues. There is permanent damage to the brain in the absence of restoration of blood flow.

The blockage in the brain vessels may be due to clot formation at the site of the blockage. Another reason for blockage is debris travelling along with circulation and blocking the blood flow in the brain vessels.

WHAT ARE THE SYMPTOMS OF ISCHEMIC STROKE?

The patients with ischemic stroke experience the following symptoms:

  • Paralysis or weakness in the legs or hands that may be in one or both sides of the body

  • Vision disorders like double vision or blindness

  • Lack of coordination

  • Confusion

  • Headache

  • Problem in walking

  • Difficulty speaking and problem in understanding the other's speech

  • Dizziness and vertigo

Patients should immediately consult the doctor even if most of the above symptoms occur even when they are not permanent.

WHAT ARE THE CAUSES OF ISCHEMIC STROKE?

The formation of a clot is the primary cause of ischemic stroke. The clot formation is usually in the heart. In most cases, this clot dissolves and causes no harm. However, this clot travels to the brain vessels and blocks them in some cases. The plaque also develops in the brain vessels and blocks them. Another severe type of ischemic stroke is global stroke. The usual cause of global stroke is a heart attack. However, it may also cause due to carbon monoxide poisoning.

WHAT ARE THE RISK FACTORS OF ISCHEMIC STROKE?

Several factors increase the risk of ischemic stroke. Some of them are:

  • Congenital heart disease

  • Sickle cell anaemia

  • High blood pressure

  • Atherosclerosis

  • Atrial fibrillation

  • High Cholesterol

  • Clotting disorders

HOW DOES THE DOCTOR DIAGNOSE ISCHEMIC STROKE?

The doctor may use the following methods to diagnose ischemic stroke:

  • Physical examination and family history: The doctor evaluates the patients based on their symptoms. He may also seek information about the family history of stroke.

  • Cranial CT scan: The doctor may also advise the patient to undergo a cranial CT scan. This test assists the doctor to determine the presence of stroke and differentiating between ischemic and hemorrhagic stroke.

  • MRI: After the stroke diagnosis, the doctor may suggest the patient undergo MRI. It will determine the cause of stroke.

  • Other tests: The doctor may advise the patient include angiography, ECG, and echocardiography.

WHAT ARE THE TREATMENT OPTIONS FOR ISCHEMIC STROKE?

The primary aim of treating ischemic stroke is to restore the flow and prevent tissue damage. Following are the treatment options for ischemic stroke:

  • Medications: The doctor may prescribe specific medicines that break up the clot. The drug also includes those that reduce the risk of stroke recurrence. The doctor may also manage these conditions if the cause is underlying conditions like atherosclerosis or blood pressure.

  • Rehabilitation: Patients with stroke may have paralysis or weakness of limbs. They may opt for rehabilitation to accelerate recovery.

HOW IS THE RECOVERY OF THE PATIENT AFTER AN ISCHEMIC STROKE?

Ischemic stroke is a severe medical condition and requires immediate treatment. With appropriate and quick intervention, many patients can retain essential functions. It is necessary to learn the symptoms of a stroke. It will help in saving the lives of themselves and others.
