PIP for Brain Injury (Acquired & Traumatic) – Can You Claim? Guide 2026

An acquired brain injury (ABI) can qualify for PIP, but it is one of the hardest conditions to put across on the form. Much of the impact is hidden, the difficulties can change from day to day, and reduced insight after an injury means many people understate how much help they really need. The key is to describe the practical, daily consequences of your injury in detail, especially where you need prompting or supervision to do everyday things safely.

What Counts as an Acquired Brain Injury?

Acquired brain injury (ABI) means any damage to the brain that happens after birth. It includes traumatic brain injury (TBI), caused by an external force such as a fall, a road traffic accident, an assault or a sports injury. It also includes non-traumatic causes, where the brain is damaged from the inside: a haemorrhage or stroke, a period without enough oxygen (hypoxic or anoxic injury), an infection such as meningitis or encephalitis, or a brain tumour and its treatment (see PIP for a brain tumour).

The lasting effects of a brain injury are often described as a "hidden disability" because they may not be visible to other people and may not show clearly on a scan. They can include:

• Cognitive difficulties: problems with memory, concentration, slowed processing speed, and executive function (planning, organising, problem-solving, starting and finishing tasks).
• Severe fatigue: overwhelming mental and physical exhaustion that mental effort and busy environments make worse.
• Behavioural and emotional change: irritability, loss of temper, disinhibition, low mood, anxiety and reduced awareness of your own difficulties.
• Communication difficulties: word-finding problems, losing the thread of a conversation, and difficulty following what others say.
• Physical and sensory effects: headaches, dizziness, changes to vision, hearing, taste or smell, and an increased risk of epilepsy and seizures.
• Physical impairment: in some injuries, weakness down one side, problems with balance and coordination, and reduced mobility.

Crucially, scans can look "normal" while the person still has major functional difficulties, and a milder injury can leave lasting symptoms (post-concussion syndrome) that persist for months or longer.

Which Activities Does a Brain Injury Affect?

Because the brain controls so much, a brain injury can affect a very wide range of PIP activities. For cognitive impairment, the need for prompting and supervision is often the most important thing to describe.

Preparing Food (Activity 1) – difficulty planning and sequencing a meal, forgetting steps, and safety risks such as leaving the hob or oven on. You may be physically able to cook but need someone to prompt you to start, to keep you on track, or to supervise you near heat and sharp knives.

Managing Therapy (Activity 3) – remembering whether you have taken medication, managing repeat prescriptions, and keeping to a complex regimen. Memory problems can mean missed or doubled doses without prompting or a dosette box.

Washing and Bathing (Activity 4) – reduced motivation and initiation meaning you do not wash unless prompted, forgetting whether you have washed, or fatigue making bathing exhausting.

Dressing and Undressing (Activity 6) – problems with sequencing (clothes in the wrong order or inside out), forgetting to dress for the weather, and needing prompting to start and finish.

Communicating Verbally (Activity 7) – word-finding difficulties, slowed processing, and losing track mid-sentence, so conversations take longer and you may need information repeated.

Reading and Understanding (Activity 8) – difficulty concentrating on and comprehending written information, re-reading the same passage, and being unable to take in letters or forms without help.

Engaging with Other People (Activity 9) – behavioural change, disinhibition, irritability, social anxiety and being overwhelmed in groups, so you may need support or encouragement to engage with people safely.

Making Budgeting Decisions (Activity 10) – difficulty with executive function and processing numbers, so you cannot reliably manage money, pay bills or check change without help.

Planning and Following Journeys (Activity 11) – memory problems and disorientation meaning you get lost, anxiety and sensory overload in busy or unfamiliar places, and being unable to plan or follow a route without support.

Moving Around (Activity 12) – where the injury has caused physical impairment such as weakness, poor balance or coordination problems, your walking distance and safety may be limited.

Why "Normal Scans" Do Not Mean No Difficulties

One of the biggest obstacles for brain injury claimants is the belief that a normal scan means there is nothing wrong. That is not how brain injury works, and it is not how PIP is assessed. PIP looks at how your condition affects your ability to carry out everyday activities, not at your imaging.

Many of the most disabling effects of a brain injury, such as diffuse axonal injury, microscopic damage and altered brain chemistry, do not show on a routine CT or MRI scan. Someone can have a completely "clean" scan and still be unable to hold down a conversation, remember a shopping list, or be left alone safely. When you complete the form, lead with the practical difficulties you live with every day rather than the scan result, and ask people who know you well to confirm what they see.

Cognitive Difficulties: How to Describe Them

Cognitive difficulties are often the heart of a brain injury claim, but words like "memory problems" or "brain fog" are too vague to tell the assessor anything. Concrete, specific examples are far more convincing. Think about memory, concentration, processing speed and executive function (planning and organising), and give real incidents:

• "I have left the hob on twice and only realised when my partner smelled burning."
• "I forget appointments unless I set three alarms, and I still miss them."
• "I cannot follow a recipe past the second step without losing my place."
• "I re-read the same paragraph several times because I lose the thread."
• "My daughter has to write out each step of a task or I do not finish it."
• "I forget what someone has told me within a few minutes."

For each example, explain what it means in practice: that you need someone to prompt you, to supervise you for safety, or to do part of the task for you. That link between the difficulty and the help you need is what scores points.

Why Prompting and Supervision Are Key

For people with cognitive impairment, the most important concept in PIP is often prompting and supervision, and it is frequently the part claimants leave out. After a brain injury you may be physically capable of cooking, washing or dressing, yet still unable to do these things reliably on your own.

• Prompting means someone reminding, encouraging or verbally guiding you to start, continue or finish an activity, without physically doing it for you.
• Supervision means someone needing to be present to keep you safe while you do something, for example staying in the kitchen because of the risk of you leaving the hob on.

Needing prompting or supervision scores points across several activities, including preparing food, washing, dressing, managing therapy, engaging with people and journeys. If a relative reminds you to take your medication, talks you through getting dressed, or cannot leave you alone with the cooker, that is exactly the kind of support PIP is designed to recognise. Describe it plainly and often.

Fatigue After Brain Injury

Fatigue is one of the most common and most underestimated effects of a brain injury. Brain injury fatigue (sometimes called neuro-fatigue) is not ordinary tiredness, and it does not reliably improve with sleep or rest. Mental effort, noise, bright light and busy environments drain you quickly, and you may "hit a wall" with little warning.

Because fatigue is invisible, it is easy to understate. Be specific about its effect on each activity and across the day: "After concentrating for half an hour I have to lie down in a dark, quiet room." "If I shower in the morning I can do nothing else for the rest of the day." "By early afternoon my speech slurs and I cannot follow what people are saying." Fatigue is also central to the reliability test, because it means you often cannot complete an activity repeatedly throughout the day or in a reasonable time.

Behavioural and Emotional Changes

Damage to the brain commonly changes behaviour and emotion, and these changes can be just as disabling as physical ones. They may include irritability and a short temper, disinhibition (saying or doing things you would not have done before your injury), low mood, anxiety, emotional outbursts, and reduced awareness of your own difficulties.

These changes are especially relevant to Engaging with Other People (Activity 9). Social situations may become overwhelming, you may avoid contact, or interactions may end in conflict. Describe specific situations and what support or encouragement you need to manage them. This can be a sensitive and upsetting area to write about, so it often helps to have a family member describe what they have witnessed, and to approach it with honesty rather than minimising it.

The Reliability Test and Day-to-Day Fluctuation

Brain injury symptoms often vary from day to day and hour to hour. A "good" hour in the morning can be followed by being unable to function by the afternoon, and a reasonable day can be followed by a wipeout. PIP must take this into account through the reliability test and the rule that you are assessed on what you can do on the majority of days.

To score a descriptor, you must be able to complete the activity:

• safely – without risk to yourself or others;
• to an acceptable standard – properly, not half-done;
• repeatedly – as often as the activity needs doing through the day; and
• in a reasonable time – not vastly slower than someone without your condition.

If you cannot meet all four on more than half of days, you should score the descriptor that reflects your difficulty. Do not let an unusually good day on the form hide your typical day. Keeping a short diary over two to four weeks, recording good and bad periods, helps show the real pattern.

Safety and Risk

Safety is a recurring theme in brain injury claims, and it directly affects scoring because an activity that cannot be done safely is not counted as done. Memory lapses, poor concentration, disorientation and reduced judgement can create real risks in everyday life, for example:

• Leaving the hob, oven or grill on, or leaving taps running.
• Forgetting whether medication has been taken, and over or under-dosing.
• Getting lost or disoriented, even on familiar routes, when out alone.
• Reduced awareness of hazards because of impaired judgement or insight.

If these risks mean someone has to supervise you, prompt you or take over part of a task, say so clearly and give examples. The need for supervision to stay safe is a recognised reason to score points across several activities.

Evidence That Helps

Strong, specialist evidence is particularly valuable for an invisible condition, because it backs up difficulties an assessor cannot see in a short assessment. Helpful evidence may include:

• Neuropsychology assessments setting out your cognitive strengths and difficulties (memory, attention, processing speed, executive function) in objective terms.
• Neuro-rehabilitation reports from a brain injury or rehabilitation team describing your functional needs and progress.
• Occupational therapy assessments describing how you manage everyday tasks at home and the support you require.
• GP and consultant letters (neurology, neurosurgery, rehabilitation medicine) confirming your diagnosis and its ongoing impact.
• Imaging history and hospital records documenting the original injury, even where later scans look normal.
• Statements from family or carers who see the daily impact and can describe the prompting, supervision and support they provide.

You do not need every item on this list, but a neuropsychology or occupational therapy report combined with a family member's account is often a powerful combination.

Frequently Asked Questions

My brain scans look normal now - can I still claim?

Yes, you may still qualify. PIP is not assessed on scan results - it is assessed on how your condition affects your daily activities. Brain injury is often a hidden disability: a CT or MRI scan can look normal while you still have major difficulties with memory, concentration, fatigue, planning and mood. Diffuse axonal injury and microscopic damage frequently do not show on routine imaging. Describe your day-to-day difficulties in detail rather than relying on the scan.

How do I describe memory and concentration problems convincingly?

Use specific, concrete examples instead of general statements. Rather than "my memory is poor", write "I have left the hob on twice and only realised when my partner smelled burning. I forget appointments unless I set three phone alarms. I cannot follow a recipe past the second step. I re-read the same paragraph because I lose the thread. I forget what someone has just told me within minutes." Explain that these problems mean you need prompting or supervision to do things safely, to an acceptable standard, repeatedly and in a reasonable time.

What does "needs prompting" mean and why does it matter for PIP?

Prompting means someone reminding, encouraging or verbally guiding you to start, continue or complete an activity, without physically doing it for you. Supervision means someone needing to be present to keep you safe. After a brain injury you may be physically able to cook, wash or dress, but you do not start, you miss steps, or you do unsafe things unless someone prompts you. Prompting and supervision score points across several activities, so describing this need is often the difference between a low award and a higher one for people with cognitive impairment.

I have post-concussion syndrome after a milder injury - can I claim?

Possibly. A blow to the head that was labelled "mild" can still cause persistent symptoms - headaches, dizziness, fatigue, poor concentration, irritability and low mood - known as post-concussion syndrome. PIP looks at functional impact, not the original severity label. If symptoms have lasted or are likely to last (broadly the required period of nine months or more) and affect your daily activities on the majority of days, you may qualify. Keep a symptom diary and get supporting evidence.

How do I describe brain injury fatigue?

Brain injury fatigue (sometimes called neuro-fatigue) is not ordinary tiredness and it does not reliably improve with rest. Mental effort, noise and busy environments drain you quickly. Be specific: "After concentrating for thirty minutes I have to lie down in a dark room. If I shower in the morning I can do nothing else that day. By early afternoon my words slur and I cannot think." Explain how fatigue makes you unable to complete activities reliably and repeatedly through the day.

My behaviour and mood have changed since my injury - is that relevant?

Very relevant. Damage to the brain commonly changes behaviour and emotion: irritability, loss of temper, disinhibition (saying or doing things you would not have before), low mood, anxiety and reduced awareness of your own difficulties. These affect Engaging with Other People (Activity 9) and can make social situations overwhelming or lead to conflict. Describe specific incidents and explain whether you need support or encouragement to engage with people safely. It can be sensitive to write about, so a family member's account often helps.

Should family or carers help describe my difficulties?

Yes. After a brain injury, reduced insight is common - you may genuinely not notice problems that are obvious to others, which can lead to understating difficulties on the form. People who see you every day can describe the prompting, supervision and support they provide and give concrete examples of memory lapses, fatigue, safety incidents and mood changes. A short written statement from a partner, parent or carer is valuable supporting evidence.
