In general, a stroke on one side of the brain can cause weakness on the opposite side of the body. With left side stroke, the right side of the body can develope weakness. With left brain stroke, a patient can lose the ability to speak, understand speech, or even both. Each patient is different so I take an individualized approach in stroke diagnosis, treatment, management, and rehabilitation.

Introduction to Stroke

When it comes to strokes, understanding the nuances is crucial for timely intervention and effective treatment. Strokes are divided into two main types: ischemic strokes, caused by a blockage in a blood vessel supplying the brain, and hemorrhagic strokes, resulting from a rupture of a blood vessel within the brain. Both types can have devastating effects, making it vital to recognize the signs and seek immediate medical attention. Learn more on our blog post about the different types of stroke.

Left-side strokes are the most commonly diagnosed type of stroke.


Understanding Left Brain Stroke


What Does It Control?

The left side of the brain controls the right side of the body. It plays a significant role in language processing, comprehension, speech, and logical reasoning. Additionally, it governs aspects of personality and emotions. Often the language ability may be affected and it is possible to develop aphasia when you lose the ability to speak or understand speech, in some cases both.

What is Damaged by Left Brain Stroke?

When a stroke occurs on the left side of the brain, it can lead to impairment in various functions, including:

  • Speech and language abilities
  • Weakness or paralysis on the right side of the body
  • Cognitive functions such as problem-solving and decision-making

Signs of Left Brain Stroke

  • Sudden weakness or numbness on the right side of the body
  • Difficulty speaking or understanding speech
  • Confusion or disorientation
  • Vision problems, particularly on the right side
  • Severe headache without any known cause

Side Effects of Left Brain Stroke

The side effects of a left-side stroke can vary depending on the severity and location of the damage. Some common side effects include:

  • Hemiplegia/hemiparesis: Numbness or weakness in the right side of the body
  • Impaired strength and coordination
  • Aphasia: Difficulty with speech and language
  • Apraxia of speech: Difficulty engaging muscles in and around one’s mouth that help forming speech
  • Cognitive deficits, such as memory problems or difficulty with problem-solving
  • Visual loss

Left Side Stroke Personality and Emotional Changes 

In addition to physical left-side stroke symptoms, strokes can also lead to emotional and personality changes. Patients may experience:

  • Depression or mood swings,
  • Impulsivity or disinhibition, 
  • Anxiety or emotional issues, such as exaggerated or overly emotional reactions. (Around 25% of stroke survivors experience emotional challenges after a stroke, according to the UK Stroke Association.)

Some patients may stay on antiplatelet drugs permanently to reduce the risk of another stroke. Antiplatelet are the first kind of blood thinner drugs and the second one is called anticoagulants.

Diagnosis of Left Side Stroke

A stroke specialist in Singapore like Dr. Manish Taneja will assess your health history and ask about your symptoms. They will also look for signs of brain problems. Diagnosing a left-side stroke typically involves:

  • a combination of medical history
  • physical examination
  • CT Scan
  • MRI
  • doppler ultrasound
  • electrocardiogram and echocardiogram (to test heart function)

Left Side Stroke Treatment Options and Management

A stroke can feel overwhelming at first, but there is always the Supreme Vascular and Intervetional Clinic team on your side to help you with post-stroke options. 

Treatment often encompasses acute interventions like clot-busting drugs and thrombectomy. These interventions are followed by rehabilitation for left-side stroke recovery exercises. A person may need physical, speech, and occupational therapy. Long-term management focuses on medication, lifestyle changes, and regular monitoring. Some stroke survivors may face fear, depression, frustration, and social isolation. These feelings are often most notable for people who experience left-side stroke paralysis and who will need new ways to be mobile.

A compassionate medical professional is pivotal for timely intervention, comprehensive care, emotional support, and patient education. These can all enhance left-side stroke recovery and improve a person’s quality of life.

Ischemic Stroke Treatment Options

For ischemic strokes, treatment may involve administering clot-busting medications such as tissue plasminogen activator (tPA) or performing a mechanical thrombectomy to remove the clot. Rehabilitation and lifestyle modifications are also essential for recovery and preventing future strokes.

  • Medications: Meds may include antiplatelet drugs, clot-busting medication (Thrombolytics), blood thinners (anticoagulants), and blood pressure medications. 
  • Mechanical thrombectomy: In some cases, doctors may use a device to remove the clot from the blood vessel manually. A trained specialist performs this procedure, usually done within a few hours of the stroke.
  • Blood pressure management: Keeping blood pressure under control is vital in preventing further damage to the brain. 
  • Cholesterol-lowering drugs: High cholesterol levels can contribute to the formation of blood clots. Medications like statins help lower cholesterol levels and reduce the risk of future strokes.

Hemorrhagic Stroke Treatment Options

In the case of hemorrhagic strokes, treatment focuses on controlling bleeding as well as reducing pressure within the skull. Treatment may also involve surgery to repair damaged blood vessels or relieve the pressure it causes in the brain. It is all dependent on left-side stroke causes. Rehabilitation and lifestyle changes are similarly vital to recovery and prevention.

  • Surgery: Some people have surgery to remove the blood clot or repair damaged blood vessels in the brain. 
  • Coil Embolization: This is a minimally invasive procedure where a catheter is guided through blood vessels to the bleeding site. 
  • Blood pressure management: Controlling high blood pressure is crucial to prevent rebleeding and reducing the risk of another stroke. 
  • Medications: Seizures can occur after a hemorrhagic stroke, so doctors may prescribe medications to prevent or control them. Patients also may need blood pressure or cholesterol medications. 
  • Intracranial pressure monitoring: In some cases, a device may be placed inside the skull to monitor pressure on the brain. This device helps doctors manage and prevent complications from increased pressure.
  • Medications: Depending on the underlying cause of the hemorrhagic stroke, doctors may prescribe medications to manage conditions like diabetes or high cholesterol to reduce the risk of future strokes.

Similar to ischemic stroke, your doctor may recommend rehabilitation therapy such as physical, speech, and occupational therapy to help regain lost functions and improve quality of life.

Left Side Stroke Rehabilitation and Recovery

After a stroke, physical therapy can help restore strength, coordination, and balance. This therapy may include exercises to improve mobility and range of motion.

Some stroke survivors may have difficulty speaking or understanding language. Speech therapy can help improve communication skills and cognitive abilities. They may also need occupational therapy. This therapy focuses on helping stroke survivors relearn tasks of daily living, including eating, dressing, and bathing. It may also involve modifying the home environment to improve safety and independence.

Adopting a healthy lifestyle, including exercise, balanced eating, smoking cessation, and limiting alcohol intake, can significantly reduce the risk of another stroke.

We’ve Got You Covered for Specialized Stroke Screening, Prevention, and Management

Imagine heart attacks where the blood flow to your heart is blocked. Similarly, a stroke occurs when the blood flow to your brain is interrupted becoming a “brain attack”. When blood supply does not reach a certain part, brain cells begin to die. Different types of stroke include ischemic strokes (blockage of blood vessel due to blood clot) or a mini stroke, a TIA (transient ischemic attack), with no permanent damage yet serious. Stroke also occurs when a blood vessel in the brain pops causing bleeding in the brain.

Certain areas of the brain can be affected by stroke and some symptoms of a stroke including cardiovascular disease, diabetes, and high blood sugar levels increase the risk of stroke whereas an active lifestyle or controlling high cholesterol reduces the risk. How well do you know stroke? Find tips to prevent and manage stroke, the differences in stroke screening tests, and the newer technology and treatments available.
