The Maple Hospital Roblox seizure update (v4.7.3) shipped on May 28 with a new Tonic-Clonic Seizure case, a relocated Neurology bay, and a four-step stabilisation that catches a lot of players out. Below is the dated timeline of what changed, the XP I logged across eleven test runs, and what the update actually means for each role.
I am Jim Liu, an independent games writer based in Sydney. I tracked the seizure update from the May 27 teaser through to the May 29 micro-hotfix, playing across three servers (14, 11, and 18 active players) as both a Level 13 Doctor and a Level 12 Nurse in the assist slot.
Every XP figure below is stopwatch-and-screenshot verified - I ran the new seizure case eleven times to confirm the solo and assisted payouts, and I timed the stabilisation steps frame by frame because the benzodiazepine window is the single most common failure point. Where I am inferring rather than observing (spawn rate on small servers, for example), I say so.

From the May 27 teaser to the May 29 hotfix, here is the seizure update as it actually rolled out - in order, with what I saw at each point.
Marizma Games posted a single screenshot to the Maple Hospital group wall on the evening of May 27 - a patient on a gurney with a new EEG monitor overlay and the caption "neuro is getting serious." No patch notes, no version number, just the image. The Discord lit up within minutes guessing it was either a stroke case or a seizure case.
I screenshotted the wall post and noted the monitor UI, because the EEG waveform in the teaser did not match any existing station. That was the first concrete sign this was a genuinely new illness and not a reskin of Mild Concussion, which was added back in the May 9 v4.7.0 drop.
The seizure update shipped quietly as v4.7.3. There was no in-game popup - I only knew it was live because the Neurology bay had visibly moved when I loaded into a 14-player server. The patient queue started spawning a new case type labelled "Tonic-Clonic Seizure" with a Severity 4 marker.
First thing I confirmed: the case is Doctor-treat, unlocking at the standard Level 10 Doctor gate. There is an optional Nurse assist slot, which is the first time the maple hospital roblox seizure update lets a Nurse meaningfully co-treat a Severity 4 emergency. The previous joint-treat case, Compound Fracture, split work between Doctor and Nurse too, but the seizure case assist is faster and cleaner.
My first seizure case took 2 minutes 40 seconds because I did the stabilisation steps out of order. The correct sequence is: airway check first, then lateral (recovery) positioning, then start the timed observation, and only administer the benzodiazepine if the seizure crosses the 90-second mark. If you give the benzo too early the case flags as over-medication and you lose the XP bonus.
The EEG station is the new piece. After stabilisation you walk the patient to the EEG station inside the reworked Neurology bay, run a 20-second reading, and the case resolves. The reading is mostly a timer - there is no diagnostic puzzle like the Allergy Relief Diagnostic Tablet. It is more of a procedural gate than a decision point.
The old neurology observation alcove behind Radiology is gone. The seizure update consolidated all neurological cases - Mild Concussion and the new Seizure case - into one dedicated Neurology bay directly opposite the Triage desk on the main floor. This is a real quality-of-life change: the old alcove was a long walk and you frequently lost the patient escort timer crossing the map.
There is a side effect worth flagging. Because the bay is now on the main floor, seizure cases draw a crowd. On busy servers I had two or three other players spectating, which is harmless but can make the EEG station hard to click if someone is standing on the interaction hotspot.
I ran the seizure case eleven times across two evenings to nail down the XP. Solo Doctor: a clean 26 XP per case, every time, no variance. With a Nurse in the assist slot the payout split 16 Doctor / 10 Nurse - so the Doctor earns less per case when assisted, but the case clears about 35 seconds faster because the Nurse handles lateral positioning in parallel.
Per-hour, the assisted route is only marginally better for the Doctor and clearly better for the Nurse, who otherwise has no access to Severity 4 XP. The seizure case at 26 XP sits just under Acute Appendicitis (28 XP) as the second-highest single-case payout in the game. But - and this matters - the spawn rate is low. I averaged two seizure cases per 40-minute session on a 14-player server.
Late on May 29 a small server-side hotfix went out (no version bump that I could see). It widened the benzodiazepine administration window slightly - before the hotfix, the over-medication flag was triggering even when players administered the benzo at exactly 90 seconds because of a one-frame rounding issue. After the hotfix I could administer at the 90-second mark without the penalty.
This is the kind of fix that does not appear in any patch notes. I only caught it because I had been failing the over-medication check on two earlier runs and then suddenly stopped failing it with identical timing. If you tried the seizure case on May 28 and lost the bonus to over-medication, retry it - the window is more forgiving now.
The seizure case is not just a new illness - the assist slot quietly changes the Nurse-Doctor relationship for Severity 4 emergencies. Here is the honest read for each role, based on the XP I logged rather than the patch teaser hype.
26 XP per case is strong, second only to Appendicitis. But the low spawn rate means you cannot grind it. Treat it as a welcome XP spike when it appears during a standard rotation, not a route you queue for.
The assist slot is the headline change for Nurses. It is the first time a Nurse earns meaningful XP (10 per case) from a Severity 4 emergency. Take the slot whenever a Doctor starts a seizure case - it is free XP you previously could not touch.
Surgeon can treat the seizure case via Doctor lineage but gains nothing over a base Doctor. If you main Surgeon, the OR is still your better XP source - the seizure case does not use the OR at all.
You cannot treat the seizure case until you unlock Doctor at Level 10. Focus on the Nurse XP buff path first - then you can both treat seizures as a Doctor and fill the assist slot as a Nurse depending on what the server needs.
If you want to know exactly how many sessions the new seizure XP shaves off your next unlock, plug your current level into the XP level calculator - it now factors the seizure case into its highest-yield quest view.
Where the new Tonic-Clonic Seizure case sits against the other May 2026 illnesses, by single-case XP and treating role.
| Illness | Severity | Role | XP / case |
|---|---|---|---|
| Acute Appendicitis | 4 | Doctor | 28 |
| Tonic-Clonic Seizure (new) | 4 | Doctor (+ Nurse assist) | 26 |
| Compound Fracture | 4 | Doctor + Nurse | 24 |
| Feline Respiratory Infection | 3 | Vet | 18 |
| Canine Hip Dysplasia | 2 | Vet | 14 |
| Allergic Dermatitis | 2 | Nurse | 13 |
| Mild Concussion | 2 | Doctor | 12 |
The takeaway: the seizure case is the second-strongest single-case XP in the game, but its low spawn rate means it cannot replace consistent rotations. It is a spike, not a staple.
Three things tripped me or other players up in the first 48 hours of the seizure update.
Another player is standing on the interaction hotspot. Because the new Neurology bay is on the main floor, seizure cases draw spectators. Ask them to step off, or re-approach from the patient's left side where the hotspot is widest.
You administered the benzodiazepine before the 90-second mark, or you tried it on May 28 before the rounding hotfix. Wait until the observation timer crosses 90 seconds, then administer. After the May 29 hotfix the 90-second mark itself is safe.
Spawn rate is deliberately low for a Severity 4 emergency. On servers under 10 players you may go a full session without one. Join a busier server (14+) if you specifically want to test the case - I saw roughly two per 40 minutes at that player count.
The seizure update (v4.7.3, May 28 2026) added a Tonic-Clonic Seizure illness (Severity 4, Doctor-treat with a Nurse assist slot), a reworked Neurology bay with a new EEG station, and a four-step stabilisation sequence: airway check, lateral positioning, timed observation, and a benzodiazepine administration if the seizure runs past 90 seconds. Full case payout is 26 XP, split 16 Doctor / 10 Nurse when two players treat together.
A solo Doctor earns 26 XP per completed Tonic-Clonic Seizure case. If a Nurse takes the assist slot, the payout splits 16 Doctor / 10 Nurse, but the case clears about 35 seconds faster because the Nurse handles lateral positioning while the Doctor preps the EEG. The seizure case sits just below Acute Appendicitis (28 XP) as the second-highest single-case XP in the game as of late May 2026.
Tonic-Clonic Seizure is a Doctor-treat case that unlocks at Level 10 (the standard Doctor unlock). There is an optional Nurse assist slot that any Nurse can fill from the patient interaction menu. Pharmacist and Receptionist cannot treat it. Surgeon can treat it (Doctor lineage) but gains no bonus over a base Doctor for this case.
The Neurology bay was moved from the back corridor next to Radiology to a dedicated room off the main hospital floor, directly opposite the Triage desk. The new EEG station is inside that room. If you remember the old observation alcove, it is gone - the seizure update consolidated all neurological cases (Mild Concussion and the new Seizure case) into this single bay.
For a Level 10+ Doctor, yes - 26 XP per case is strong and the EEG step is fast once you learn it. But the spawn rate is deliberately low (it is a Severity 4 emergency), so you cannot farm it reliably on quiet servers. On a 14-plus player server I saw roughly two seizure cases per 40-minute session. Treat it as a bonus when it appears, not a primary XP route. For consistent XP, standard Doctor rotations or the Nurse buff path are still better per hour.
Now that you know the seizure case pays 26 XP, see how it stacks against your next unlock using the XP level calculator - and check the full update log for the rest of the May 2026 patch cycle this seizure update belongs to.
