Understanding Spatial Neglect for Student Nurses
Learn how spatial neglect can affect a patient's awareness of one side of their body or environment, how it may appear during everyday care and why sudden new neglect requires urgent neurological assessment.
What is spatial neglect?
Spatial neglect is a neurological problem in which a person has reduced awareness of one side of their body or surrounding space. It can occur following neurological injury, including stroke.
One side may be ignored
The patient may respond normally to information on one side while failing to notice similar information on the other.
Their own body may be affected
A patient may appear less aware of one arm, leg or side of their body.
Objects may be missed
Food, furniture, people or other objects on the affected side may repeatedly go unnoticed.
What might spatial neglect look like?
The first clue is often not a formal neurological test. It may be an unusual pattern you notice while helping the patient with ordinary activities.
Food left on one side
The patient may repeatedly eat food from only one side of their plate.
One side may be missed
Washing, shaving, applying make-up or brushing hair may be completed on only one side.
Colliding with objects
The patient may repeatedly bump into doorframes, furniture or other obstacles on one side.
People may be overlooked
The patient may fail to respond to someone approaching or speaking from the affected side.
Part of the page may be missed
Words or information on one side of written material may be overlooked.
A limb may be ignored
The patient may appear unaware of the position or presence of one limb.
Spatial neglect is not the same as visual field loss
Both can cause a patient to miss information on one side, but they are different neurological problems. Distinguishing between them requires appropriate assessment.
Visual information is missing
Part of the patient's visual field may not be seen because of a problem affecting the visual pathway.
Awareness is reduced
The patient may not attend or respond normally to one side of their body or surrounding space.
Recognise rather than diagnose
Notice the pattern, describe what you observe and escalate new neurological findings for appropriate assessment.
Observe, compare and connect
Establish baseline
Find out whether the patient's behaviour and awareness are different from their normal presentation.
Observe everyday activity
Notice how the patient eats, communicates, moves and interacts with both sides of their environment.
Compare both sides
Look for a repeated difference in attention or response between one side and the other.
Connect neurological findings
Consider speech, vision, facial movement, strength, sensation, coordination and consciousness.
Build the wider neurological picture
Any facial weakness?
New facial asymmetry may accompany other focal neurological abnormalities.
Any unilateral weakness?
Compare limb movement and strength and identify any new side-to-side difference.
Has communication changed?
Look for new dysarthria, aphasia or difficulty understanding instructions.
Any visual disturbance?
Visual symptoms or field abnormalities may coexist with other neurological changes.
Any altered feeling?
New numbness or sensory loss can form part of the wider focal neurological picture.
Has alertness changed?
Reduced consciousness or rapid neurological deterioration requires urgent assessment.
New neglect combined with facial weakness, limb weakness, speech change or other focal neurological findings requires urgent escalation.
Neglect can create significant safety risks
Obstacles may not be noticed
Reduced awareness of one side can increase the risk of collisions, trips and falls.
A limb may be vulnerable
Poor awareness of an affected arm or leg may increase the risk of accidental injury or unsafe positioning.
Meals may appear unfinished
Leaving food on one side may affect intake if the underlying problem is not recognised.
When reduced awareness needs urgent escalation
- Sudden new failure to notice one side of the environment.
- New apparent lack of awareness of one side of the body.
- Neglect associated with facial weakness.
- Neglect associated with unilateral arm or leg weakness.
- New neglect with dysarthria or aphasia.
- Neglect with sudden visual disturbance.
- New neurological changes following a head injury.
- Neglect associated with reduced consciousness or rapid deterioration.
Place neglect within structured assessment
Airway
Confirm airway patency and respond immediately to any airway compromise.
Breathing
Assess respiratory rate, oxygen saturation, respiratory pattern and work of breathing.
Circulation
Assess pulse, blood pressure and perfusion within the patient's wider clinical condition.
Disability
Assess consciousness, pupils, vision, speech, facial movement, strength, sensation and coordination according to local practice.
Exposure
Look for injury, illness or other relevant clinical findings while maintaining dignity.
Escalate
Communicate significant new neurological abnormalities promptly and follow the appropriate local emergency pathway.
Recognising neglect during everyday care
Example
A patient who was functioning normally earlier in the day is eating lunch.
You notice that they have eaten everything from the right half of the plate but have not touched food on the left.
When you approach from their left, they initially appear unaware that you are standing beside them. They also have new weakness in their left arm.
You recognise the pattern: new reduced awareness of the left side + new unilateral weakness.
You perform a structured assessment, establish when the patient was last known to be at their normal neurological baseline and escalate immediately according to the local emergency pathway.
Describe what the patient is doing
Example escalation
“I'm concerned about Mrs Patel. Earlier she was interacting normally with both sides of her environment. She is now repeatedly ignoring objects and people on her left side and has left all the food on the left half of her plate. She also has new left arm weakness.”
This communicates the change from baseline, side affected, observed behaviour and associated neurological finding.
Spatial neglect assessment errors to avoid
- Assuming neglect and visual field loss are the same thing.
- Failing to observe the patient during ordinary activities.
- Calling the patient distracted without considering neurological change.
- Failing to compare behaviour with the patient's baseline.
- Ignoring repeated collisions or missed objects on the same side.
- Assessing awareness without connecting it to strength, speech and vision.
- Documenting only “neglect” without describing what was observed.
- Failing to consider the immediate falls and injury risk.
Observe → compare → connect → escalate
Watch everyday behaviour
Notice whether the patient consistently misses people, objects or parts of their own body on one side.
Build the neurological picture
Compare with baseline and connect awareness with vision, speech, strength, sensation and consciousness.
Describe the pattern
State exactly what changed, which side is affected and what other neurological abnormalities are present.
Connect awareness with the wider neurological assessment
Spatial neglect becomes more meaningful when considered alongside visual fields, facial movement, speech, limb strength, sensation, coordination and the patient's normal neurological baseline.
