Hemispatial Neglect After Right MCA Stroke: Causes and Treatment

59 minutes ago
2 min read

ntroduction: Hemispatial neglect is a neurological condition that can occur after a right middle cerebral artery (MCA) stroke. It causes a person to pay little or no attention to the left side of their body or surrounding environment, even when their eyes can see and their basic vision is intact.

What Is Hemispatial Neglect?

Hemispatial neglect, also called unilateral spatial neglect, is a disorder of attention and awareness. After a right MCA stroke, survivors may ignore people, objects, or activities on their left side. For example, they might eat food from only the right half of a plate, fail to notice their left arm, or bump into objects on their left while walking. This condition differs from visual field loss because the primary problem involves attention rather than vision alone.


Causes of Hemispatial Neglect After Right MCA Stroke:

The right MCA supplies blood to important brain regions involved in spatial awareness, attention, and processing information from both sides of the environment. When a stroke damages areas such as the right parietal lobe, frontal regions, or connected neural networks, the brain may struggle to recognize or respond to left-sided information.

The severity of neglect varies depending on the size and location of the injury. Some survivors experience mild inattention, while others have significant difficulty recognizing their left side. Neglect may also occur alongside left-sided weakness, sensory changes, impaired balance, or reduced awareness of their own limitations.


Common Signs and Symptoms:

Symptoms may include ignoring food on the left side of a plate, dressing only the right side of the body, overlooking objects on the left, reading only the right portion of a page, or turning the head predominantly to the right. These difficulties can increase the risk of falls, injuries, and problems with everyday activities.


Diagnosis and Assessment:

Healthcare professionals assess neglect through observation, neurological examinations, and structured tasks. These may include line-bisection tests, cancellation tasks, copying drawings, and assessments of daily activities. Clinicians also evaluate vision, sensation, movement, and cognition to identify other contributing problems.


Treatment and Rehabilitation:

Treatment focuses on improving attention, safety, and independence. Occupational therapists may teach visual scanning, encouraging survivors to turn their eyes and head toward the left. Anchoring a bright marker on the left side of a page or using verbal reminders can help direct attention.

Prism adaptation, repeated visual-search exercises, and other attention-training approaches may benefit selected patients. Physical and occupational therapy can incorporate safe movement and daily activities. Family members should approach from the affected side when appropriate, provide calm reminders, and follow the rehabilitation team's guidance. Treatment must be individualized because no single technique works for everyone.


Conclusion:

Hemispatial neglect after a right MCA stroke can significantly affect independence, mobility, and safety. Early assessment, consistent rehabilitation, and supportive caregiving can help survivors improve awareness and participate more confidently in daily life. Recovery varies, so progress should be monitored by qualified healthcare professionals. Sudden new or worsening neurological symptoms require emergency medical attention.

About Dr. Viveck Baluja and KneeTie Vascular Neurology

Dr. Viveck Baluja, MD, is a board-certified vascular neurologist (American Board of Psychiatry and Neurology — Vascular Neurology) practicing telemedicine across California, Michigan, and Colorado, with additional consultation services available to international families, particularly in India.

KneeTie offers three focused services: emergency stroke second opinions delivered within 24 hours, traumatic brain injury (TBI) consultations for survivors and caregivers, and same-day adult ADHD evaluations for residents of CA, MI, and CO.

Stroke Second Opinion

After a stroke, families often have minutes to make decisions. Dr. Baluja provides a second set of expert eyes from a board-certified vascular neurologist — reviewing imaging, hospital records, and current treatment — typically within 24 hours of request. Common questions include: Was tPA appropriate? Should we pursue thrombectomy? What is the recovery outlook? What rehabilitation makes sense?

TBI Consultation

Traumatic brain injury recovery is rarely linear. Dr. Baluja helps patients and families understand recovery timelines, treatment options, post-concussion syndrome, and red flags that warrant emergency evaluation. Consultations typically last 50 minutes and are scheduled within the same week.

Same-Day Adult ADHD Evaluation

A real evaluation by a board-certified neurologist — not a 7-minute screening. Dr. Baluja's ADHD evaluations include comprehensive history, sleep and lifestyle assessment, and behavioral strategy alongside any medication discussion. Available same-day for residents of California, Michigan, and Colorado.

Why a Vascular Neurologist?

Vascular neurology is a subspecialty focused on stroke, cerebrovascular disease, and brain blood flow — among the rarest neurology subspecialties in the U.S. Most online telehealth services use general practitioners or nurse practitioners. KneeTie is led by a board-certified vascular neurologist with full state licensure and HIPAA-compliant telehealth infrastructure.

Schedule a consultation: Use the booking calendar above to choose a service and reserve a time. For active stroke or post-tPA emergencies, email gorungo@kneetie.com directly with "URGENT" in the subject line.
