Neglect After Stroke: What It Can Affect and What Rehabilitation Can Address

What does “neglect” mean after stroke?

After some strokes, the brain gives less attention or priority to information from one side. This is often called spatial neglect, unilateral neglect, or hemispatial neglect.

The difficulty is usually most noticeable on the side opposite the injured hemisphere. Left-sided neglect after a right-hemisphere stroke is commonly discussed, but neglect can be more varied than a simple left-versus-right problem.

Neglect may involve space close to the body, farther-away space, or the person’s own body. It may affect visual, tactile, auditory, or movement-related behavior. A person may also have limited awareness that anything is being missed.

This does not mean the person is choosing to ignore one side. It reflects a change in how the brain attends to and represents information.

How is neglect different from visual-field loss?

Visual-field loss means part of the visual field is unavailable because of injury somewhere along the visual pathway. Neglect is primarily an attention-and-awareness disorder.

The two can look similar in daily life. Either can contribute to missed objects, difficulty reading, collisions, or trouble navigating. They can also occur together.

The distinction matters because assessment, insight, strategies, and rehabilitation planning may differ. Observing that someone misses objects on one side cannot establish which problem is present.

Is neglect the same as sensory loss or weakness?

No.

With sensory loss, the nervous system may not detect or accurately process touch, temperature, pain, or body-position information. With neglect, sensory information may be available but receive less attention or influence behavior less reliably.

Weakness reduces the ability to generate or control movement. Neglect may reduce spontaneous use or attention toward a limb even when some movement is possible. Weakness, sensory loss, and neglect can coexist, which is why a functional problem should not be assigned to one cause without assessment.

Is neglect a memory problem?

Neglect is not primarily a memory disorder. A person may remember instructions yet fail to notice part of a scene, body, or task.

It is also not interchangeable with “cognitive impairment.” Attention, awareness, executive function, language, perception, and memory are related but distinct. Stroke can affect several of them at once.

What can neglect affect in daily life?

Neglect may contribute to difficulty with:

• finding food or objects on one side;
• grooming or dressing part of the body;
• reading the beginning or end of a line;
• locating a wheelchair brake, armrest, or mobility aid;
• avoiding doorframes, furniture, curbs, or people;
• using an arm during a task;
• following activity across a busy environment;
• walking, wheelchair mobility, road crossing, work, or driving-related tasks; and
• recognizing the full extent of a safety problem.

How is neglect assessed?

Assessment may combine:

• the person’s and family’s description of everyday difficulties;
• observation during personal care, reaching, reading, mobility, and navigation;
• standardized paper-and-pencil or functional measures;
• examination of vision, sensation, movement, language, and cognition; and
• review of awareness, attention, fatigue, and environmental demands.

What can rehabilitation address?

Rehabilitation may aim to improve safety, increase attention to missed information, support task completion, adapt the environment, and help the person and family understand the problem.

Depending on the individual, a plan may include structured cues, changes to task layout, practice within meaningful activities, feedback, visual-search strategies, limb activation, or selected technology-based approaches. Some interventions are compensatory: they help the person complete an activity despite persistent neglect. Others attempt to change the underlying attention bias.

The evidence does not support one universal program. Neglect is heterogeneous, trials use different definitions and outcomes, and improvement on a test does not always translate into durable improvement in daily life. Treatment selection therefore requires professional assessment and monitoring.

Who may be involved?

Occupational therapists often assess how neglect affects dressing, eating, reading, object use, home activity, and community participation. Physical therapists may examine mobility, orientation, obstacle negotiation, and how attention affects movement. Neuropsychologists may characterize attention, perception, awareness, and related cognitive functions. Nurses, physicians, speech-language pathologists, vision professionals, and other team members may contribute according to the setting and the person’s needs.

Safety and urgent changes

Neglect can affect mobility, wheelchair use, cooking, medication routines, street crossing, work, and driving-related performance. Safety decisions should be based on individualized assessment rather than one home task.

Sudden new one-sided inattention, weakness, numbness, vision change, speech difficulty, severe imbalance, or other possible stroke symptoms requires emergency evaluation. This article cannot determine whether a current symptom is caused by stroke or whether an activity is safe.

Key Takeaways

What to carry forward.

• Neglect is a disorder of attention and awareness, not deliberate ignoring.
• It is distinct from visual-field loss, sensory loss, weakness, memory loss, and general cognitive impairment.
• More than one impairment can occur together.
• Effects may appear across the body, nearby space, distant space, and real-world activity.
• Assessment should combine standardized measures with functional observation.
• Rehabilitation is individualized, and effects of specific approaches remain variable.
