Spatial neglect, also known as hemispatial neglect or unilateral neglect, is a neurological condition that affects a person’s ability to perceive and attend to one side of their body or their environment. This condition often results from brain damage, most commonly occurring after a stroke. In this article, we will explore spatial neglect in simple terms, including its types, causes, symptoms, diagnostic tests, treatment options, drugs, and surgery, providing an accessible overview of this condition.
Types of Spatial Neglect:
Spatial neglect can manifest in different ways, and there are several types of neglect, including:
- Personal Neglect: People with personal neglect may ignore or forget to care for one side of their own body, such as neglecting to dress one arm or eat food from one side of the plate.
- Peripersonal Neglect: Peripersonal neglect involves ignoring objects and events that occur on one side of the body within arm’s reach. This can lead to difficulties in daily tasks like reaching for objects or writing.
- Extrapersonal Neglect: Extrapersonal neglect extends beyond the individual and affects their awareness of one side of their surrounding environment. For example, a person may only eat food from one side of their plate or neglect objects on one side of the room.
Common Causes of Spatial Neglect:
Spatial neglect is primarily associated with brain injuries or damage to specific areas of the brain. Common causes include:
- Stroke: The most frequent cause of spatial neglect, usually occurring when a stroke affects the right hemisphere of the brain.
- Traumatic Brain Injury (TBI): Head injuries that damage specific brain regions can lead to neglect.
- Brain Tumor: Tumors in certain brain areas can disrupt spatial awareness.
- Hemorrhage: Bleeding in the brain can damage brain structures involved in spatial perception.
- Infections: Certain brain infections can result in spatial neglect symptoms.
- Multiple Sclerosis (MS): MS lesions in the brain can cause neglect-like symptoms.
- Alzheimer’s Disease: In advanced stages, Alzheimer’s can lead to spatial neglect.
- Parkinson’s Disease: Some Parkinson’s patients may experience neglect due to cognitive impairments.
- Brain Surgery: Surgical procedures involving the brain can sometimes result in neglect.
- Aneurysm: Ruptured or treated aneurysms can impact brain areas responsible for spatial awareness.
- Encephalitis: Brain inflammation can disrupt spatial perception.
- Migraines: Severe migraines may cause transient neglect symptoms.
- Carbon Monoxide Poisoning: Brain damage from carbon monoxide exposure can lead to neglect.
- Brain Lesions: Non-cancerous lesions in the brain may affect spatial awareness.
- Epilepsy: Seizures originating from specific brain areas can result in neglect.
- Vascular Disease: Reduced blood flow to the brain can cause neglect symptoms.
- Hydrocephalus: Accumulation of cerebrospinal fluid can impact brain function.
- Drug or Alcohol Abuse: Substance abuse can lead to brain damage and neglect.
- Inflammation: Autoimmune diseases that affect the brain can cause spatial neglect.
- Aging: Some elderly individuals may experience mild neglect as a result of natural brain changes.

Common Diagnostic Tests for Spatial Neglect:
Diagnosing spatial neglect often involves a combination of clinical assessments and specialized tests, including:
- Clinical Evaluation: A neurologist or neuropsychologist assesses the patient’s symptoms and medical history.
- Line Bisection Test: The patient is asked to mark the center of a line, revealing any bias toward one side.
- Clock Drawing Test: Drawing a clock face helps detect neglect in spatial organization.
- Cancellation Tests: Patients identify and mark specific targets within grids, highlighting neglect patterns.
- Line Cancellation Test: Marking specific lines on a page to assess neglect.

- Drawing and Copying Tasks: Patients are asked to draw or copy geometric figures, revealing neglect in their representations.
- Reading Tasks: Assessing reading comprehension and identifying skipped words or lines.
- Functional Tasks: Observing the patient performing daily activities to evaluate neglect in action.
- Magnetic Resonance Imaging (MRI): Brain imaging to identify structural brain abnormalities.
- Computerized Tomography (CT) Scan: Detects brain lesions or damage.
- Positron Emission Tomography (PET): Measures brain activity and function.
- Electroencephalogram (EEG): Records electrical activity in the brain.
- Functional MRI (fMRI): Shows brain activity during tasks related to neglect.
- Neuropsychological Assessments: Cognitive tests to evaluate specific deficits.
- Visual Field Testing: Measures peripheral vision and identifies neglect patterns.
- Eye Movement Assessments: Tracking eye movements during visual tasks.
- Sensory Testing: Evaluating sensory perception on both sides of the body.
- Occupational Therapy Assessments: Identifying specific difficulties in daily living.
- Anatomy Assessment: Mapping the brain areas affected by damage using advanced techniques.
Common Treatment Approaches for Spatial Neglect:
The treatment of spatial neglect aims to improve the patient’s awareness and functional abilities. Treatment options include:
- Occupational Therapy: A key component of treatment, focusing on daily tasks and activities.
- Visual Scanning Training: Teaching patients to systematically scan their environment.
- Compensatory Strategies: Using aids like mirrors or reminders to address neglect.

Surgery for Spatial Neglect:
Surgical interventions for spatial neglect are uncommon and typically focus on addressing underlying conditions, such as brain tumors, aneurysms, or vascular malformations. The goal is to reduce the source of damage to the brain, potentially alleviating neglect symptoms. Specific surgical procedures depend on the individual’s diagnosis and the location of the problem within the brain. Surgeons work to remove or repair the affected tissue, ultimately aiming to improve the patient’s overall neurological function.
Conclusion:
Spatial neglect is a complex neurological condition that can significantly impact an individual’s daily life. Understanding its types, causes, symptoms, diagnostic tests, treatment options, drugs, and potential surgical interventions is crucial for both patients and caregivers. Early diagnosis and a multidisciplinary approach to treatment, including therapies, medications, and supportive care, can help individuals with spatial neglect regain their independence and improve their quality of life. If you or someone you know experiences symptoms of spatial neglect, seeking medical attention and rehabilitation support is essential for the best possible outcomes.
