Hemispatial Neglect After Stroke: What It Is and How to Help

Some stroke survivors have more than weakness in an arm or leg. They seem to "forget" one side of the world around them, most often the left side after damage to the right side of the brain. This is called hemispatial neglect (or unilateral spatial neglect). It is not blindness and it is not laziness; it is a disorder of how the brain directs attention.

A person may eat only half of the plate, bump into door frames on one side, or shave half of the face, while sincerely believing nothing is wrong. This guide describes what families can notice, how the care team approaches it, and what is generally safe to try at home. It is educational and does not replace an assessment by the treating doctor.

Neglect is often confused with a visual field defect. In a field defect the visual pathway is damaged, and the person usually knows something is missing and compensates by turning the head. In neglect the eyes may work well, but attention does not reach the affected side, and the person often lacks awareness of the problem.

Both can occur together, which is why a stroke survivor may need an eye examination and a neurological one. Telling them apart is a job for clinicians using simple structured tests, not for guesswork at home.

The signs are often small, so writing them down helps:

• Eating food from one side of the plate and then complaining that the meal was too small.
• Keeping the head and eyes turned toward the unaffected side, or not looking at someone who speaks from the affected side.
• Colliding with doors, furniture or people on the affected side while walking or using a wheelchair.
• Ignoring the weak arm or leg, which may hang off the chair without being noticed.
• Drawing or writing on only one half of a page, or starting to read in the middle of a line.
• Forgetting to comb the hair or wash one side of the face.

The brain balances attention between the two sides of space through wide networks, including areas in the parietal lobe. When a stroke disturbs these networks, the balance tips and the side opposite the damage receives less attention. That is why neglect is more common and more severe after right-hemisphere strokes, although it can occur after left-sided strokes in a milder form.

Many people improve during the first weeks and months, but the degree of recovery varies and nobody can promise a timeline or an outcome.

The danger of neglect is that it does not look like an illness, so it may be noticed late. It can raise the risk of falls and collisions, slow gait training because the person does not attend to the edges of the path, expose the neglected arm to injury or pressure, and lead to refusal of exercises on a limb that does not feel like a part of the body.

Food intake can also fall, so families should watch mealtimes. Finding neglect early is therefore part of a good rehabilitation plan. Our guide to fall prevention strategies offers general ideas for a safer home.

Assessment combines observation with short standardised tests carried out by the doctor or therapist, such as crossing out lines or shapes on a page, marking the middle of a line, or copying a drawing. The therapist also watches how the person performs real tasks like eating and moving between rooms.

Most importantly, tell the clinician what you see at home. People with neglect often underestimate or deny their difficulty, so family observations are valuable.

Plans differ according to the assessment, and may include:

• Visual scanning training: practising turning the head and eyes toward the neglected side in a systematic way, for example finding a coloured marker at the page edge.
• Cueing: a bright colour or light on the affected side to draw attention, reduced step by step.
• Activating the affected side: including the weak arm in two-handed tasks under supervision.
• Task-specific training: eating, dressing and passing through doorways with the right level of help.
• Environmental set-up: arranging the room so important items are easy to notice, then gradually shifting them.

The therapist decides the intensity and progression for each person.

These general tips are safe for most people, but check them with the treating team.

• Approach and speak calmly, standing in front of the person or on the affected side.
• Place food and tools where they can be seen, then gently remind the person to scan the plate from edge to edge.
• Add a coloured strip to the left rim of the plate or table.
• Keep walkways clear, especially on the affected side, and light corridors well.
• Support the weak arm on a cushion or tray so it does not dangle or get pressed.
• Use short, clear instructions and repeat them without blame.

Arguing to make the person admit the problem rarely works. Calm repeated guidance is usually more effective.

Make meals a calm training opportunity. Serve the plate where the person can see it, then rotate it gradually once the first part is finished, or remind the person to touch the plate rim with the affected hand before starting. Plates with a coloured rim can help. If coughing or choking happens during meals, tell the doctor promptly, because swallowing problems need a separate assessment.

In the bathroom, place the mirror so the affected side is visible, remind the person to check both sides when shaving or combing, and look at the skin on the neglected side for redness or sores that may not be felt.

Most hazards are collisions and falls. At first it is usually better for a family member to walk on the affected side, not the unaffected one, because this draws attention to that side and lowers the chance of bumping. Ask the person to look toward the affected side before turning or going through a door, remove loose rugs and install grab rails where appropriate.

For wheelchair users, check the position of the affected arm and leg before moving, and avoid squeezing through narrow gaps on the neglected side. The therapist will choose the right level of assistance for each person.

Good intentions can sometimes make things harder.

• Treating it as stubbornness: the person is not ignoring you on purpose; attention itself is disturbed.
• Always keeping everything on the unaffected side: this is comfortable today but does not train attention toward the neglected side.
• Pulling the weak arm hard: this can injure the shoulder. Support it gently as the therapist shows you.
• Leaving the person alone at meals or when walking in the early days.
• Waiting to tell the doctor because it seems normal after a stroke.

Most families do not need special equipment. After checking with the care team, you might use coloured tape on the edge of a table or plate, a plate with a raised rim, good lighting in corridors and bathrooms, a gentle reminder alarm to scan the room, and a small card saying "look to the left" in a visible place. Cues are temporary supports and should be reduced as attention improves.

Constant correction can be frustrating for the survivor, and repeating instructions can wear out the family. It helps to see neglect as a neurological symptom, not a lack of effort. Use encouraging words, break tasks into small steps and notice small gains. If you see persistent sadness, anxiety or poor sleep, tell the doctor: depression is common after stroke and can be treated.

Many people improve, particularly in the first weeks and months after the stroke, while others keep some degree of difficulty. Recovery depends on the size and location of the injury, age, other medical conditions and how regular the rehabilitation is. We do not promise a cure or a timeline, but regular practice and a safe environment can reduce the effect on daily life. For a wider view of rehabilitation, see stroke rehabilitation.

Specific notes help the clinician more than general impressions. Record when the problem shows (during meals, turning, when tired), on which side the person collides, whether reminders help, and how drawing or writing looks. A photo of the plate after a meal can show clearly that one half was ignored. Bring the medicine list and earlier scans or tests, and ask when to follow up and which signs mean you should return earlier.

Call emergency services at once for a sudden change in alertness or speech, new weakness on one side, facial drooping, a sudden severe headache or a seizure, as these may signal a new stroke or complication. See the doctor early if the person is falling repeatedly, eating noticeably less, has sores or redness on the neglected side, or seems increasingly low in mood.

Neglect shows itself clearly in the home, with the real food, furniture and routes. The Bedaya home physiotherapy team can watch how the person interacts with the environment, adjust how a room is arranged and train the carer in safe assistance. You can read about the comprehensive home neuro assessment or brain injury rehabilitation.
