hemorrhagic stroke treatment and prevention Singapore

A hemorrhagic stroke is a life-threatening disorder that happens when a blood artery in the brain ruptures, causing bleeding and damage to surrounding brain tissue. Unlike ischemic stroke, which occurs when blood flow is blocked, hemorrhagic stroke is caused by bleeding, and the effects can be more serious if not treated immediately. This article will look at the causes, treatment choices, physical effects, and preventive measures for hemorrhagic stroke, with a particular emphasis on treatment and prevention in Singapore.

Global Prevalence of Hemorrhagic Stroke

Stroke is a major public health concern worldwide. While ischemic strokes account for around 87% of all strokes, the remaining 13% are hemorrhagic strokes. Despite being less prevalent, hemorrhagic strokes are associated with higher fatality rates and significant long-term impairments.

According to the World Health Organization (WHO), around 17 million individuals worldwide have a stroke each year, with 2.5 million of those instances being hemorrhagic strokes. Hemorrhagic stroke accounts for half of all stroke-related deaths, making it the deadliest type of stroke. Hemorrhagic stroke rates are rising in Southeast Asia, particularly Singapore, with an increased prevalence among older persons and those with uncontrolled hypertension.

Contributing Factors to Hemorrhagic Stroke

Hemorrhagic stroke can be caused by a variety of reasons, including chronic illnesses, lifestyle choices, and medical anomalies. These risk factors can be roughly divided into changeable and non-modifiable groups.

Non-Modifiable Risk Factors:

  1. Age: The risk of hemorrhagic stroke rises with age, especially after age 55. Blood arteries weaken over time, making them more likely to burst.
  2. Gender: Males are slightly more likely to have a hemorrhagic stroke than females, although women have worse results when they do.
  3. Genetics and Family History: A family history of stroke or brain aneurysms increases the risk of having a hemorrhagic stroke.
  4. Ethnicity: According to research, certain ethnic groups, such as Asians, Africans, and Hispanics, are more likely to experience hemorrhagic stroke. In Singapore, stroke incidence is significantly greater among Malays and Indians than among Chinese Singaporeans.

Modifiable Risk Factors:

  1. Hypertension (High Blood Pressure): This is the major cause of hemorrhagic stroke because it weakens blood vessel walls and raises the chance of rupture.
  2. Cerebral Aneurysms: Refers to weak places in blood vessels that can blow out and cause bleeding in the brain. These aneurysms can be congenital or develop over time as a result of hypertension or other causes.
  3. Arteriovenous Malformations (AVMs): These are aberrant tangles of blood vessels that connect arteries and veins in the brain. If they rupture, they can result in a hemorrhagic stroke.
  4. Blood Thinning Medications: Excessive usage of blood thinners, such as warfarin, can raise the risk of brain hemorrhage.
  5. Smoking: Doing this weakens blood arteries, increasing the risk of aneurysms and other vascular problems.
  6. Substance Abuse: Recreational drug use, particularly cocaine and amphetamines, is highly associated with hemorrhagic stroke due to their ability to raise blood pressure.

Available Treatment Options for Hemorrhagic Stroke in Singapore

When it comes to hemorrhagic stroke treatment and prevention, Singapore has a highly developed healthcare system that includes advanced medical technologies and highly-skilled healthcare experts. Immediate treatment is crucial for controlling bleeding, lowering intracranial pressure, and preventing additional brain damage.

1. Emergency Care and Diagnosis

The first step in treating hemorrhagic stroke is to diagnose it quickly, which is usually done with imaging tests like computed tomography (CT) or magnetic resonance imaging (MRI). These scans aid in determining the location and intensity of the bleeding, allowing for more targeted treatment.

2. Surgical interventions

Surgery may be required in the event of serious bleeding or the discovery of an aneurysm or AVM. The purpose of surgery is to stop the bleeding, reduce pressure on the brain, and repair any damaged blood vessels. Surgery possibilities include:

  • Craniotomy: A surgical technique that involves removing a part of the skull in order to gain access to the brain and halt bleeding. The surgeon could remove a blood clot, repair a broken vessel, or treat an aneurysm.
  • Aneurysm Clipping: For patients with ruptured cerebral aneurysms, surgical clipping may be used. This entails inserting a small metal clip into the base of the aneurysm to block blood flow to the damaged vessel and prevent further rupture.
  • Endovascular Coiling: A minimally invasive alternative to clipping that includes introducing a catheter into an artery and guiding it to the location of the aneurysm. A coil is then inserted into the aneurysm to stimulate blood clotting and seal the area.

3. Medication Management

Medication is essential for treating hemorrhagic stroke. Depending on the etiology of the stroke, doctors may give drugs to lower blood pressure, manage pain, or reverse the effects of blood thinners. When anticoagulants contribute to a stroke, reversal medications can be used to stop the bleeding.

4. Post-Stroke Rehabilitation

Following a hemorrhagic stroke, many people require rehabilitation to regain physical and cognitive function. In Singapore, facilities such as Tan Tock Seng Hospital, National University Hospital, and Singapore General Hospital provide multidisciplinary stroke rehabilitation programs. These programs include physiotherapy, occupational therapy, and speech therapy to assist patients in recovering and regaining independence.

5. Long-Term Monitoring

Patients who survive a hemorrhagic stroke frequently require long-term monitoring for high blood pressure and vascular malformations such as AVMs or aneurysms. Regular checkups and imaging tests are essential for preventing future strokes.

Physical Changes After Suffering from a Hemorrhagic Stroke

The physical and cognitive repercussions of a hemorrhagic stroke differ substantially depending on the location and severity of the bleeding. Survivors of hemorrhagic stroke may endure a variety of symptoms, some of which are long-term or even permanent.

1. Paralysis and Weakness

Hemorrhagic strokes can result in paralysis or muscle weakness on one side of the body. This can impair mobility, balance, and coordination, making it difficult for patients to walk or perform daily activities independently.

2. Speech and Language Impairments

Damage to the parts of the brain responsible for speech, such as Broca’s or Wernicke’s, can cause aphasia, a disorder in which patients struggle to talk, understand language, or make cohesive sentences.

3. Cognitive Decline

Many survivors suffer from cognitive deficits such as memory loss, difficulty concentrating, and difficulties solving problems. These issues can impair a patient’s capacity to work or sustain relationships.

4. Sensory Deficits

Sensory deficits such as vision issues, numbness, or altered sensation are typical following a hemorrhagic stroke. For example, some people may lose the capacity to feel pain or temperature on one side of their body.

5. Emotional and Behavioral Changes

Hemorrhagic strokes can produce significant changes in attitude and behavior. Depression, anxiety, anger, and even personality changes are frequent following a stroke, necessitating both medical and psychological intervention.

Natural Ways to Prevent Hemorrhagic Stroke

While medical intervention is required to treat hemorrhagic stroke, maintaining a healthy lifestyle can dramatically lower the risk of developing one. The natural preventive measures listed below focus on hemorrhagic stroke treatment and prevention in Singapore.

1. Maintain Healthy Blood Pressure

High blood pressure is the most important risk factor for hemorrhagic strokes. Regular blood pressure monitoring and dietary changes, such as limiting salt intake, boosting potassium, and eating a diet high in fruits, vegetables, and whole grains, can naturally lower blood pressure.

2. Exercise Regularly

Physical activity lowers blood pressure, promotes cardiovascular health, and reduces stress. To preserve vascular health, perform at least 150 minutes of moderate aerobic exercise per week, such as brisk walking or swimming.

3. Quit Smoking

Smoking weakens blood arteries, raising the chance of a stroke. Quitting smoking can help to enhance vascular integrity and minimize the risk of stroke by decreasing blood pressure and preventing aneurysm formation.

4. Limit Your Alcohol Intake

Excessive alcohol drinking can cause hypertension and raise the risk of hemorrhagic stroke. Limiting alcohol consumption to reasonable amounts (one drink per day for women and two for men) can help protect against stroke.

5. Manage Stress

Chronic stress is associated with hypertension and other cardiovascular disorders. Mindfulness activities like yoga, meditation, and deep breathing exercises can help reduce stress and avoid hemorrhagic stroke.

6. Eat a Heart-Healthy Diet

A diet high in omega-3 fatty acids (found in fish), whole grains, lean proteins, and plenty of fruits and vegetables can help lower cholesterol, regulate blood pressure, and prevent hemorrhagic strokes.

7. Avoid Substance Abuse

Avoiding recreational drugs like cocaine and amphetamines is crucial because they elevate blood pressure and can cause blood vessels in the brain to break.
