Concussion Recovery Timeline: What the First 6 Weeks Look Like

After the headache and the fog, the first question every concussed person asks is the same one: how long until I feel like myself? The honest answer has a shape, even though it does not have a single number. This article walks through the first six weeks the way we walk patients through them in clinic.

One framing note before the weeks. Concussion recovery is a distribution, not a deadline. The 6th International Consensus Statement on Concussion in Sport, developed in Amsterdam in 2022, describes most people recovering clinically within days to about a month. Plenty of normal recoveries use all of that month. A timeline is a map of what usually happens, not a promise about your brain.

Days 0 to 2: relative rest, not a dark room

The old advice was strict rest until every symptom disappeared. The Amsterdam consensus retired that idea. The current recommendation is relative rest for the first 24 to 48 hours: cut back on screens, skip training and heavy thinking, sleep as much as your body asks for, but live your life at low intensity rather than lying in a dark room.

The dark-room approach feels intuitive and tends to backfire. Extended strict rest deconditions you, feeds anxiety, and is associated with slower recovery rather than faster. In the first two days, the job is to take the pressure off, not to remove all input.

This is also the window for medical clearance. A physician should assess any suspected concussion, and worsening headache, repeated vomiting, increasing confusion, or one-sided weakness in these first days is an emergency department visit, not a wait-and-see.

Days 3 to 10: light movement earns its place early

This is the part that surprises people. The consensus statement supports starting light, symptom-tolerable physical activity, such as walking or an easy stationary bike, within the first couple of days, and prescribed aerobic exercise below the symptom threshold within roughly days 2 to 10. Done at the right dose, early aerobic work reduces the odds of symptoms persisting, which makes it one of the few genuinely protective things you can do in week one.

The dose matters more than the activity. "Symptom-tolerable" means an intensity where symptoms rise no more than mildly and settle quickly after you stop. In our clinic we often anchor this with a monitored exertion test, and at home the working rule is simple: if an activity spikes your symptoms hard, the dose was too big, so shrink it rather than shelving movement altogether.

Cognitive load follows the same logic. Short blocks of reading, screens, or focused work with breaks, scaled up as tolerated. Most people can begin a gradual return to work or school in this window, even with symptoms still present.

Weeks 2 to 4: the staged climb back

By the second week, recovery usually looks like a staircase: graded steps back into thinking, screens, work or school, and exercise, each held until symptoms accept it. The international protocol behind this is covered in detail in our guide to return-to-learn and return-to-work staging, which pairs with this article. The short version is that learn and work come back before sport, and each step up should hold for at least a day or so before the next.

Setbacks inside this window are normal and informative. A flare after a long day is not re-injury. It is dosing information, and the plan adjusts. What we watch for is the overall slope across the month: bumpy but rising is the standard pattern. Parachute Canada's concussion guideline describes the same staged structure used across Canadian sport.

By the end of week four, the majority of adults are at or near their baseline. If that is you, the remaining job is finishing the return-to-sport steps and not skipping the last ones.

Weeks 4 to 6: when normal slow becomes worth investigating

The consensus statement uses a specific label once symptoms outlast the expected window: persisting symptoms, generally applied beyond about four weeks. This is not a scarier diagnosis. It is a flag that says stop waiting passively and start looking for the specific drivers, because lingering concussion symptoms usually have findable causes.

The usual suspects are treatable. The vestibular system, the neck, exertion intolerance, visual strain, sleep disruption, and mood each produce symptoms that imitate "concussion still healing," and each has its own treatment path. Dizziness is the clearest example: an inner-ear problem and a neck-driven problem produce similar complaints with different fixes, which is why we wrote a separate piece on telling vestibular and cervicogenic dizziness apart. Targeted vestibular therapy is one of the better-evidenced tools for the dizziness cluster.

So the six-week mark is a decision point, not a cliff. Still clearly improving: keep climbing the stages. Plateaued since week three or four: book a reassessment that screens the vestibular system, the neck, and exertion tolerance specifically, rather than another week of waiting. Our concussion physiotherapy page covers what that assessment and treatment plan looks like.

What tends to stretch the timeline

A few patterns we see lengthen recovery, offered as clinic observations alongside the consensus literature. Going back to full days of screen-heavy work in week one, usually out of obligation rather than readiness. Skipping the aerobic-exercise window entirely and resting for a month. A neck injury from the same incident that never got assessed, common in car crashes. Poor sleep that nobody treated. And a previous concussion with an unfinished recovery underneath this one.

None of these doom a recovery. They are levers, and most of them can be adjusted at any point in the six weeks.

Coverage when the concussion came from a crash or a workplace injury

Concussions from motor vehicle crashes fall under ICBC's pre-approved treatment framework, which covers physiotherapy in the first 12 weeks without waiting for adjudication. Our ICBC physiotherapy guide covers the claim number, booking, and what happens past 12 weeks. Workplace concussions run through WorkSafeBC instead, with its own claim and approval flow. Bring the claim number either way and we handle billing directly.

If you are somewhere in the six weeks right now

Match your week to the map. Days 0 to 2: relative rest and a medical check. Week one: start walking, gently. Weeks two to four: climb the stages and expect bumps. Past four weeks without clear improvement: book an assessment that looks at the vestibular system, the neck, and exertion tolerance rather than waiting it out. At Launch Rehab, a four-week plateau triggers a systematic screen of the vestibular system, the neck, and exertion tolerance rather than another week of generic rest, because each of those drivers has a different treatment path. The recoveries that go best in our clinic are the ones where the dose of activity was adjusted early and often, not the ones that waited for symptoms to vanish on their own.

Frequently asked questions

How long does a concussion take to heal?

Most adults recover clinically within days to about a month, per the Amsterdam consensus statement. Slower-than-average is still common and usually still normal, especially when symptoms are clearly trending down. A plateau past the four-week mark is the point to book a reassessment that looks specifically at the vestibular system, the neck, and exertion tolerance rather than waiting longer.

Should I rest in a dark room until symptoms are gone?

No. Current guidance recommends relative rest for only the first 24 to 48 hours, then a gradual return to activity below the symptom threshold. Prolonged strict rest is associated with slower recovery, since it deconditions the body and can feed anxiety rather than protect the brain.

When can I exercise after a concussion?

Light, symptom-tolerable activity like walking can usually start within the first couple of days, and structured aerobic exercise below the symptom threshold within about days 2 to 10. Contact sport waits until you have cleared the full return-to-sport stages with no symptoms. A monitored exertion test can help set the right starting intensity if the threshold is hard to judge at home.

What is post-concussion syndrome?

Current consensus language calls it persisting symptoms after concussion, generally meaning symptoms beyond about four weeks. It signals that specific drivers like the vestibular system, the neck, or exertion intolerance should be assessed and treated, not that the brain is permanently injured. Most of these drivers respond to targeted treatment once they are identified, rather than needing more time to pass on their own.

Do I need a referral for concussion physiotherapy?

No. Physiotherapy is direct-access in BC, and concussion from a crash is covered under ICBC pre-approval in the first 12 weeks. A physician assessment early on is still important for medical clearance, and workplace concussions run through WorkSafeBC's separate claim and approval process instead of ICBC.

Can I look at screens after a concussion?

Usually, in short blocks scaled to what your symptoms tolerate, rather than a full ban. The Amsterdam consensus statement supports resuming reading, screens, and focused cognitive work early, with breaks, once the first 24 to 48 hours of relative rest have passed. If a specific block of screen time clearly spikes symptoms, shorten that block rather than avoiding screens entirely.

When can I go back to work or school after a concussion?

Often within the first couple of weeks, on a graded schedule rather than all at once. Most people can begin a gradual return to work or school once the initial 24 to 48 hours of relative rest are over, with cognitive load increased step by step as symptoms allow. Our guide to return-to-learn and return-to-work staging covers the staged protocol in more detail.

What is a symptom-tolerable activity level?

It means an intensity where your symptoms rise no more than mildly during the activity and settle back down quickly afterward. This threshold, not a fixed number of days, is what current concussion guidance uses to pace both physical activity and cognitive load through the first weeks. A physiotherapist can help set this threshold with a monitored exertion test if it is hard to judge on your own.

Why do concussion symptoms sometimes get worse before they get better?

A flare after a busy day is common and does not usually mean the injury has worsened. It is more often a sign that the dose of activity, whether physical or cognitive, went past what the brain could currently tolerate that day, and the plan needs adjusting rather than abandoning. Recovery in the first six weeks is typically bumpy but trending upward overall, not a straight line.

Should I see a physiotherapist or a doctor first after a concussion?

See a physician first for medical clearance, since any suspected concussion needs a physician assessment to rule out more serious injury. A physiotherapist becomes useful once that clearance happens, particularly for staging return to activity and for addressing specific drivers such as the vestibular system or the neck if symptoms persist past about four weeks.
