PIP for Myasthenia Gravis 2026: Fatigable Weakness and How to Claim

Updated June 2026 · 10 min read

Can you get PIP for myasthenia gravis? Yes. MG is assessed on how it affects your day to day life, not on the diagnosis. Its defining feature - muscle weakness that worsens with use and through the day, then partly recovers with rest - maps directly onto the one word in PIP law that most claimants never use: "repeatedly". You only count as able to do an activity if you can do it again and again, as often as the day requires. MG claims commonly score on Activity 12 (moving around), Activity 4 (washing and bathing), Activity 1 (preparing food) and Activity 2 (eating and drinking), with reading and speech affected when eyes and bulbar muscles are involved.

This guide shows how to turn fatigability into descriptor language, which activities each muscle group hits, and how to stop a 9am assessment from erasing your 4pm reality.

What Myasthenia Gravis Does

Myasthenia gravis is an autoimmune condition in which antibodies disrupt the signal between nerve and muscle. The result is weakness that is fatigable: muscles work at first, then fail with repetition, and are usually worse later in the day, in heat, during infection or under stress. Ocular MG causes drooping eyelids (ptosis) and double vision; generalised MG adds weakness of the arms, legs and neck and, in many people, the bulbar muscles used for chewing, swallowing and speech. At its most serious, a myasthenic crisis affects breathing and is a medical emergency. Treatment - pyridostigmine, steroids, immunosuppressants, sometimes thymectomy or IVIG - helps most people but often leaves real limits, and the medication itself can carry heavy side effects. The DWP scores none of this by name: it scores the functional limits, so your job is translation.

"Repeatedly": the Word That Decides MG Claims

Under regulation 4(2A) of the Social Security (Personal Independence Payment) Regulations 2013, you only count as able to do an activity if you can do it:

Key phrase for your form: "My weakness is fatigable: I can begin most tasks but cannot complete or repeat them, and by afternoon I cannot do them at all. Per regulation 4(2A) I cannot carry out these activities safely, to an acceptable standard, repeatedly or in a reasonable time on the majority of days."

Which PIP Activities Does Myasthenia Gravis Affect?

Activity 12: Moving Around

Activity 12: Moving Around (mobility)

  1. Can stand and then move more than 200 metres 0
  2. Can stand and then move more than 50 but no more than 200 metres 4
  3. Can stand and then move unaided more than 20 but no more than 50 metres 8
  4. Can stand and then move using an aid more than 20 but no more than 50 metres 10
  5. Can stand and then move more than 1 but no more than 20 metres 12
  6. Cannot, either aided or unaided, stand or move more than 1 metre 12

The distance you can manage reliably and repeatedly is what counts - not your best single effort. If you can walk 100 metres once but your legs then fail, or your walking collapses to a few metres by late afternoon, the descriptor that reflects the majority of your day applies. Name any aid (stick, rollator, wheelchair for distance) and describe what happens after the first effort: the second attempt is the honest measure of MG. See Activity 12 in detail.

Activity 4: Washing and Bathing

Activity 4: Washing and Bathing (daily living)

  1. Can wash and bathe unaided 0
  2. Needs to use an aid or appliance to wash or bathe 2
  3. Needs supervision or prompting to wash or bathe 2
  4. Needs assistance to wash either their hair or body below the waist 2
  5. Needs assistance to get in or out of a bath or shower 3
  6. Needs assistance to wash their body between the shoulders and waist 4
  7. Cannot wash and bathe at all and needs another person to do it 8

Washing your hair means holding your arms above shoulder height - exactly the proximal, fatigable movement MG attacks first. If your arms fail mid-wash, you need a shower seat (an aid, 2 points), someone within reach in case your legs give way (supervision, 2 points), or help with your hair (assistance, 2 points), map it to the ladder honestly. Hot water makes MG weakness worse for many people, which is worth saying because assessors rarely know it.

Activity 2: Taking Nutrition (Eating and Drinking)

Bulbar MG turns the safest-looking activity dangerous: chewing fatigues mid-meal, swallowing becomes unreliable, and choking or aspiration is a real risk. Needing food cut up, needing meals adapted (soft food), eating with supervision because of choking risk, or taking far longer than normal to finish a meal all score under Activity 2 - and the "safely" limb of regulation 4(2A) does the heavy lifting. If you have ever had an aspiration event or crisis admission, include the hospital records.

Activities 1, 6, 8 and Speech

How much is YOUR PIP worth?

Describe the Whole Day, Not the First Hour

MG claims fail when the form, or the assessment, captures the rested morning version of you. The honest unit of measurement for MG is a full day.

Weak (0 points)
I have myasthenia gravis. I get weak and tired easily and have double vision sometimes. My tablets help.
Strong (8–12 points)
My weakness builds through every day. In the morning I can walk about 100 metres; by mid-afternoon I cannot manage 20 and use a rollator indoors. I can start washing my hair but my arms fail after about 30 seconds, so my husband finishes it, and I use a shower seat in case my legs give way. Chewing fatigues halfway through a meal: my food is cut small and softened after I choked twice last year, once needing A&E. By evening my speech slurs and my eyelids droop so I cannot read. Pyridostigmine helps for about three hours per dose, and I am on azathioprine, but this is my pattern on a normal treated day.

The strong version measures fatigability hour by hour, names the aids and the helper, evidences the choking risk, and states it is the treated baseline. That points to Activities 12, 4, 2, 1 and 8.

The Assessment: Do Not Let 9am Speak for 4pm

The biggest MG trap is assessment timing. If you are seen in the morning, fresh from rest, the report may record "no significant weakness observed". Counter it explicitly: tell the assessor "you are seeing my best hour - by this afternoon I will not be able to lift my arms", ask them to record the diurnal pattern, and consider requesting an afternoon slot, or a phone or home assessment as a reasonable adjustment under the Equality Act 2010. Informal observations count, so do not perform.

Related Conditions

If You Are Refused

Fluctuating, fatigable conditions are refused more often than they should be, usually off the back of a rested-morning assessment. Do not give up.

  1. Mandatory Reconsideration (within one month of the decision letter). Ask for the assessment report, then dispute each activity using the "repeatedly" limb of regulation 4(2A) and your diary's morning-vs-afternoon evidence. See our full Mandatory Reconsideration guide.
  2. First-tier Tribunal (within one month of the MR result). Around two in three appeals succeed, and tribunals understand fatigability far better than initial assessments.

Frequently Asked Questions

Can you get PIP for myasthenia gravis?

Yes. Myasthenia gravis is assessed on how it affects you day to day, not on the diagnosis. Its defining feature, muscle weakness that worsens with use and through the day, maps directly onto PIP's reliability test: you only count as able to do an activity if you can do it repeatedly. MG claims commonly score on moving around (Activity 12), washing and bathing (Activity 4), preparing food (Activity 1), eating and drinking (Activity 2) and reading (Activity 8) where double vision or drooping eyelids interfere.

How much PIP can you get for myasthenia gravis?

It depends on your scores. PIP has a daily living part (standard £76.70/week, enhanced £114.60) and a mobility part (standard £30.30, enhanced £80.00) for 2026/27. Generalised MG that limits walking, self-care and eating can reach both components. The maximum, with both enhanced rates, is around £10,119 a year.

How does PIP deal with weakness that gets worse through the day?

Through the reliability test in regulation 4(2A): you only count as able to do an activity if you can do it safely, to an acceptable standard, repeatedly, and in a reasonable time. Being able to walk 100 metres once in the morning does not mean you can do it reliably if you cannot repeat it, or cannot do it at all by the afternoon. Describe your worst part of the day and how quickly each muscle group fatigues, not your best morning performance.

Which PIP activities does myasthenia gravis affect most?

Moving around (Activity 12), where walking distance collapses with repetition. Washing and bathing (Activity 4), because raising your arms to wash your hair is classic proximal weakness. Preparing food (Activity 1), where lifting pans and chopping fatigue the arms. Eating and drinking (Activity 2), where bulbar weakness affects chewing and swallowing. Dressing (Activity 6) for overhead garments, communicating where speech becomes slurred with use, and reading (Activity 8) where double vision or drooping eyelids interfere.

Does choking risk or a past myasthenic crisis matter for PIP?

Yes. The "safely" limb of regulation 4(2A) means an activity you can only do with a risk of harm does not count. Bulbar weakness that brings choking risk when eating, or fatigue that makes stairs and baths dangerous, engages it directly. A past myasthenic crisis or aspiration event is strong evidence that the risk is real, so include hospital records of it.

What evidence helps a PIP claim for myasthenia gravis?

A neurologist's letter confirming the diagnosis (antibody results, single-fibre EMG if done) and current severity; your medication list (pyridostigmine, steroids, immunosuppressants, IVIG or plasma exchange); hospital records of any myasthenic crisis; a diary recording how each day's strength declines and what you cannot repeat; and a statement from someone who sees the evening version of you. Evidence of fatigability and daily variation is the heart of an MG claim.

My myasthenia is well controlled on medication. Can I still claim?

PIP is scored on how you function now, with treatment. If pyridostigmine and immunosuppression have genuinely restored normal, repeatable function on most days, you are unlikely to score points. But many people remain limited between doses, fatigue by afternoon, or cannot sustain activity despite treatment, and steroid or immunosuppressant side effects count too. Describe your function across a whole day on your usual medication, honestly.
