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.

Common Questions About Left-Sided Stroke Symptoms, Treatment and Recovery
What does a left-sided stroke mean?
A left-sided stroke occurs when there is damage to the left side of the brain, usually due to a blockage of blood flow (ischaemic stroke) or bleeding in the brain (haemorrhagic stroke).
Because the left side of the brain controls the right side of the body, a left-sided stroke commonly affects:
- Right-sided weakness or paralysis
- Speech and language abilities
- Reading and writing skills
- Movement coordination
- Ability to perform daily activities
The effects of a left-sided stroke vary depending on which areas of the brain are affected and the severity of the stroke.
What are the symptoms of a left-sided stroke?
Common symptoms of a left-sided stroke may include:
- Weakness or numbness on the right side of the body
- Difficulty speaking or understanding language
- Problems with reading or writing
- Facial weakness, especially on one side
- Difficulty performing familiar tasks
- Changes in movement and coordination
Other common stroke warning signs include:
- Sudden facial drooping
- Sudden difficulty speaking
- Sudden vision changes
- Severe dizziness or loss of balance
- Sudden severe headache
Stroke symptoms can appear suddenly and require urgent medical attention.
Why does a left-sided stroke affect the right side of the body?
The brain controls the opposite side of the body because many nerve pathways cross between the brain and spinal cord.
This means:
- Left side of the brain → controls the right side of the body
- Right side of the brain → controls the left side of the body
A left-sided stroke may therefore affect movement on the right side, while also impacting language because areas responsible for speech and communication are commonly located in the left side of the brain.
Can someone recover from a left-sided stroke?
Yes, recovery is possible after a left-sided stroke, although outcomes vary between individuals.
Recovery depends on factors such as:
- The size and location of the stroke
- How quickly treatment was provided
- The severity of neurological changes
- Age and overall health
- Rehabilitation progress
Recovery may include:
- Physiotherapy to improve strength and movement
- Occupational therapy to regain independence
- Speech and language therapy
- Cognitive rehabilitation
- Medical treatment to reduce future stroke risk
Early assessment and a personalised rehabilitation plan can support recovery.
What treatments are available after a left-sided stroke?
Stroke treatment depends on:
- Whether the stroke is caused by a blood clot or bleeding
- How quickly treatment begins
- The underlying cause of the stroke
- The patient’s overall health
Treatment may include:
Emergency stroke treatment
For eligible patients with an acute ischaemic stroke, treatments may be used to restore blood flow to the brain.
Identifying and treating the cause
Stroke prevention depends on understanding why the stroke occurred, which may involve assessing:
- Carotid artery narrowing
- Heart rhythm problems such as atrial fibrillation
- Blood pressure and cholesterol levels
- Other vascular risk factors
Rehabilitation and recovery support
Rehabilitation helps patients regain function and adapt to changes after stroke.
Understanding Left Brain Stroke
Left-side strokes are the most commonly diagnosed type of 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.
When to Consider a Stroke Specialist Assessment
A stroke can affect movement, communication and independence. A specialist assessment helps identify the cause of the stroke, evaluate future risks and develop an appropriate treatment and prevention plan.
Consider arranging a specialist assessment if you:
- Have experienced weakness or numbness affecting one side of your body.
- Have been diagnosed with a left-sided stroke.
- Have difficulty with speech, movement or daily activities after stroke.
- Have experienced a transient ischaemic attack (TIA or mini stroke).
- Want to understand why the stroke occurred.
- Have concerns about preventing another stroke.
- Need guidance on recovery expectations and rehabilitation.
- Want a second opinion regarding stroke treatment options.
At the Supreme Vascular and Interventional Clinic, stroke assessment focuses on understanding the underlying cause of your stroke, reviewing brain and vascular imaging, and developing a personalised approach to treatment and prevention.

Stroke Prevention Tips: How to Avoid High Cholesterol
Controllable risk factors are lifestyle choices that can be changed to reduce the risk of having a stroke including managing your cholesterol.
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”, affecting a blood vessel and surrounding brain function. When blood supply does not reach a certain part, brain cells begin to die. Different types of stroke include ischemic strokes or a mini stroke, a TIA (transient ischemic attack). Common risk factors include high blood pressure, which increases strain on the blood vessel and raises the likelihood of a stroke. Symptoms can vary, but may include difficulty in speaking and other changes depending on how blood flow is affected. Understanding risk factors and acting early can make a difference. It’s important to work closely with a specialist to monitor your health and reduce stroke risk.
