How long does it take to wake up from a stroke?

Waking up from a stroke depends on the severity of the stroke and how much damage it caused. Some people recover consciousness quickly, while others can take days, weeks or even months to wake up. The time it takes to regain consciousness is an important factor in the overall recovery process.

What happens when you have a stroke?

During a stroke, blood flow to part of the brain is interrupted, causing brain cells (neurons) in that area to die. The effects of a stroke depend on where it occurs and how much of the brain is damaged.

Common stroke symptoms include:

  • Numbness or weakness on one side of the body
  • Trouble speaking or understanding speech
  • Vision problems
  • Dizziness or loss of balance and coordination
  • Severe headache

When stroke symptoms begin, some people retain consciousness but are unable to speak or move one side of their body. Others lose consciousness completely. The faster a stroke is treated, the more brain cells can be saved.

What does it mean to “wake up” after a stroke?

“Waking up” refers to regaining consciousness and recovering awareness after being unconscious from a severe stroke. This transition is medically referred to as “emerging from a coma” or “arousing from a comatose state.”

Coma is a state of profound unconsciousness in which the person cannot be awakened and shows no signs of awareness. It is different from sleep – people in a coma cannot be aroused even with very strong stimulation. There are different levels of consciousness between full coma and being awake and aware.

As people start recovering from coma, they go through gradual stages like:

  • Minimal consciousness – brief periods of awareness and wakefulness
  • Vegetative state – awake but not aware of self or environment
  • Confusional arousals – periods of confusion and disorientation

Emerging from “coma” is a process, not a single moment. The time it takes to progress through these stages and regain full consciousness varies widely.

Factors affecting how long it takes to wake up

Several key factors determine the timeline for regaining consciousness after a stroke:

  • Extent of brain damage – Large strokes or those affecting key areas can disrupt consciousness longer.
  • Swelling – Strokes cause inflammation that can further impact surrounding areas.
  • Individual differences – Age, health, and other factors affect resilience.
  • Treatment – Quick treatment to restore blood flow improves outcomes.
  • Neurological care – Careful medical management can optimize recovery.

Strokes affect each person differently. Mild strokes may cause only brief unconsciousness, while the most severe can result in coma lasting weeks or months.

Timeline for waking up after a stroke

Although each case is unique, general patterns have emerged regarding recovery of consciousness after a stroke:

  • Regaining minimal consciousness – within 2 to 4 days
  • Opening eyes – within 1 week
  • Responding to voices – within 2 weeks
  • Following commands – within 4 weeks
  • Mean time to emerge from coma – 2 to 4 weeks

In one study looking at large strokes affecting an entire side of the brain (hemispheric infarction), the timeline was:

  • 50% regained consciousness within 5 days
  • 90% regained consciousness within 2 weeks

However, some severe strokes can result in prolonged coma lasting months.

Rapid recovery

Some patients get lucky and consciousness returns relatively quickly. Within hours to days, they can open their eyes, recognize loved ones, and even talk or follow commands.

Quick recovery is more likely with milder strokes, quicker treatment, younger age, and other favorable factors. But it varies individually even with major strokes.

Gradual recovery

More typically, regaining consciousness is a gradual process that unfolds over days to weeks. Subtle signs of recovery appear, then become more consistent.

Early signs often include:

  • Sleep/wake cycles
  • Eye opening
  • Blinking
  • Visual tracking

As the brain heals, the person becomes increasingly alert and interactive. Meaningful recovery toward full consciousness takes weeks but can certainly be quicker.

Prolonged unconsciousness

Severe strokes or complications sometimes result in prolonged coma lasting weeks or months. Additional brain damage can occur. The chances of regaining consciousness decline over time but is still possible.

Outcomes are generally better for younger patients without significant pre-existing damage. But uncertainty remains when consciousness has not returned within 4 to 8 weeks.

What level of recovery is expected?

The extent of recovery after a stroke varies based on factors like:

  • Amount of damage
  • Area of brain affected
  • Patient’s age and health
  • Timeliness of treatment
  • Access to rehabilitation services

Some people recover most or nearly all functions over time. Others are left with significant lingering effects like:

  • Paralysis or weakness on one side
  • Vision or speech problems
  • Memory and thinking deficits
  • Changes in personality and behavior

Still, regaining consciousness is the essential first step toward further recovery. Ongoing rehab and therapy can continue to improve skills and independence.

Why timing of consciousness matters

Quicker recovery of consciousness:

  • Enables early rehabilitation efforts
  • Reduces risks of medical complications
  • Correlates with better long-term outcomes
  • Suggests less severe brain damage

Factors like age and stroke severity are hard to change. But prompt treatment to restore blood supply, expert stroke care, and access to rehabilitation can all help optimize the chances and timeline for regaining consciousness.

What is the treatment during unconsciousness?

Critical care during coma focuses on:

  • Preserving brain function – Precise regulation of temperature, blood pressure, oxygen levels, glucose levels, and cranial pressure.
  • Preventing complications – Like infections, blood clots, bed sores.
  • Nutrition – Feeding tubes are often needed.
  • Weaning from ventilation – Gradual reduction of mechanical breathing support.
  • Medications – Drugs that promote wakefulness or reduce swelling may help.
  • Physical/occupational therapy – Passive movement helps maintain mobility.

The goals are to stabilize the person, promote natural recovery, and prevent any additional harm. This requires constant monitoring and medical management.

Tests to monitor progress

Tests like MRI scans can visualize the stroke damage. Repeating them later can show if bleeding or swelling has decreased.

Neurological exams assess brain function. Simple tests determine levels of consciousness and physical responsiveness.

  • Squeeze my hand
  • Wiggle your toes
  • Open your eyes
  • Follow this pen with your eyes

More complex tests evaluate cognitive abilities if the person can respond reliably.

Tracking scores on neurological exam components can document subtle improvements over time. Each small gain provides hope during the long process of recovering consciousness.

Coping with the uncertainty

The waiting game for consciousness to return can be emotionally exhausting for families. Maintaining realistic hope is challenging. Patience and taking things one day at a time are essential.

Ways to cope include:

  • Learning about comas and neuro recovery
  • Relying on social support and counseling
  • Practicing relaxation and self-care
  • Keeping a journal
  • Talking to your loved one as if they can hear

Celebrate each subtle sign of progress. Stay tuned in to medical advice but remain cautiously optimistic. With time, diligence and support, waking up from stroke is possible.


Regaining consciousness after a stroke can take anywhere from hours to weeks or longer depending on severity and other factors. While each case is unique, most people begin to show early signs of awakening within days to a few weeks. But the full process of recovering awareness may take a month or more. With intensive monitoring and neurological care, the timeline and extent of recovery can be optimized. Above all, retaining hope during the long process of awakening is key.
