Frequently Asked Questions

Most people recover from a concussion within 10-14 days. However, recovery time varies significantly based on several factors:

Typical Recovery Timeline:

• Mild concussions: 7-10 days

• Moderate concussions: 2-4 weeks

• Severe or repeated concussions: 4-12 weeks or longer

Factors that affect recovery time:

• Age (older adults and children may take longer)

• History of previous concussions

• Severity of the initial injury

• Pre-existing conditions (migraines, anxiety, ADHD)

• How quickly treatment begins

• Compliance with rest and rehabilitation protocols

About 10-30% of people develop post-concussion syndrome (PCS), where symptoms persist beyond 3 months. Early intervention with vestibular rehabilitation and guided exercise protocols can significantly improve recovery outcomes.

If symptoms persist beyond 2-3 weeks, consult a healthcare provider who specializes in concussion management.

Prolonged concussion symptoms (lasting more than 2-4 weeks) affect approximately 10-30% of concussion patients and can occur for several reasons:

Common causes of prolonged symptoms:

• 1. Vestibular dysfunction: Damage to the balance system causes ongoing dizziness and visual problems

• 2. Cervical (neck) injury: Neck trauma often accompanies concussions and causes headaches and dizziness

• 3. Autonomic nervous system dysregulation: Affects heart rate, blood pressure, and exercise tolerance

• 4. Vision problems: Convergence insufficiency, tracking issues, and light sensitivity

• 5. Sleep disruption: Poor sleep prevents proper brain healing

• 6. Psychological factors: Anxiety about recovery can amplify symptoms

What you can do:

• Seek evaluation from a concussion specialist

• Start vestibular rehabilitation if you have dizziness or balance issues

• Begin graded aerobic exercise (sub-symptom threshold)

• Address sleep problems

• Consider vision therapy if you have eye-related symptoms

Prolonged symptoms don't mean permanent damage. With proper treatment, most people with post-concussion syndrome eventually recover fully.

Seek immediate emergency care if you experience any of these red flag symptoms after a head injury:

Emergency symptoms (call 911 or go to ER):

• Loss of consciousness for more than 30 seconds

• Seizures

• Repeated vomiting

• One pupil larger than the other

• Extreme drowsiness or can't be awakened

• Slurred speech that's getting worse

• Increasing confusion

• Weakness or numbness in arms/legs

• Clear fluid from nose or ears

See a doctor within 1-2 days if:

• You have a persistent headache

• Dizziness that doesn't improve

• Memory problems

• Difficulty concentrating

• Vision changes

• Balance problems

• Sleep disturbances

• Mood changes (irritability, sadness)

Schedule a follow-up if:

• Symptoms haven't improved after 10-14 days

• Symptoms are interfering with work or school

• You're unsure about when to return to activities

Early medical evaluation helps establish a baseline and treatment plan, which improves recovery outcomes.

Dizziness and vertigo are different sensations, though people often use the terms interchangeably.

Dizziness is a general term that includes:

• Lightheadedness (feeling faint)

• Unsteadiness (feeling off-balance)

• Wooziness (foggy or floating feeling)

• Disorientation (spatial confusion)

Vertigo is a specific type of dizziness:

• A false sensation that you or your environment is spinning or moving

• Often described as the room spinning

• Usually caused by inner ear or brain problems

• Often accompanied by nausea

How to identify what you're experiencing:

| Symptom | Likely Cause |
|---------|--------------|
| Room spinning | Vertigo (vestibular) |
| Lightheaded when standing | Blood pressure/circulation |
| Off-balance but no spinning | Balance dysfunction |
| Floating/detached feeling | Anxiety or vestibular |

Common causes by type:

• Vertigo: BPPV, vestibular neuritis, Meniere's disease, concussion

• Lightheadedness: Dehydration, low blood pressure, anemia, heart issues

• Unsteadiness: Vestibular damage, peripheral neuropathy, muscle weakness

Understanding the type of dizziness you have helps your doctor determine the cause and best treatment approach.

Post-concussion dizziness typically improves within 2-4 weeks, but can persist longer in some cases.

Typical timeline:

• Days 1-7: Dizziness is common and often most intense

• Weeks 2-4: Gradual improvement for most people

• Months 1-3: About 20-30% still have some dizziness

• Beyond 3 months: 5-10% have persistent symptoms

Factors that affect duration:

• Severity of the concussion

• Whether the vestibular system was directly affected

• History of previous concussions or vestibular problems

• Starting rehabilitation early vs. waiting

• Age (older adults often take longer)

Types of post-concussion dizziness:

• 1. Vestibular: Triggered by head movement, lying down, or looking up

• 2. Cervicogenic: Related to neck injury, often with neck pain

• 3. Visual: Triggered by busy visual environments or screens

• 4. Exertional: Occurs with physical activity

What helps:

• Vestibular rehabilitation exercises

• VOR (vestibular-ocular reflex) training

• Gradual return to activity

• Treating neck problems if present

• Managing triggers while building tolerance

If dizziness persists beyond 4 weeks, seek evaluation from a vestibular specialist or concussion clinic. Targeted rehabilitation can significantly speed recovery even months after the initial injury.

BPPV (Benign Paroxysmal Positional Vertigo) is the most common cause of vertigo, affecting about 2.4% of people at some point in their lives. It's highly treatable with simple repositioning maneuvers.

What causes BPPV:

• Tiny calcium crystals (otoconia) in your inner ear become dislodged

• When you move your head, these crystals move through the semicircular canals

• This sends false signals to your brain, causing brief but intense vertigo

Typical BPPV symptoms:

• Brief episodes of intense spinning (usually 30-60 seconds)

• Triggered by specific head movements:

- Rolling over in bed
- Looking up
- Bending over
- Tilting your head back

• May include nausea

• No hearing loss (if present, consider other diagnoses)

Treatment (repositioning maneuvers):

• 1. Epley Maneuver: Most effective for posterior canal BPPV (90% of cases)

- Success rate: 80-90% after 1-3 treatments

• 2. Semont Maneuver: Alternative to Epley

• 3. BBQ Roll: For horizontal canal BPPV

• 4. Brandt-Daroff Exercises: Home exercises for maintenance

What to expect:

• Most people improve after 1-3 treatments

• Some residual dizziness for 1-2 weeks is normal

• BPPV can recur (30-50% within 5 years)

• Learning home maneuvers helps manage recurrences

A trained vestibular therapist or ENT doctor can perform diagnostic tests to confirm which ear and canal is affected, ensuring the correct maneuver is used.

The vestibular-ocular reflex (VOR) is an automatic eye movement that keeps your vision stable when your head moves. It's one of the fastest reflexes in the human body.

How the VOR works:

• 1. Sensors in your inner ear detect head movement

• 2. This signal travels to your brain stem

• 3. Your brain instantly moves your eyes in the opposite direction

• 4. Result: Your gaze stays fixed on a target despite head movement

Why the VOR matters:

• Allows you to read while walking

• Keeps the world stable when you turn your head

• Essential for balance and spatial orientation

• Works in just 10-15 milliseconds (faster than conscious thought)

When the VOR is impaired:

• Objects appear to bounce or blur when you move your head (oscillopsia)

• Difficulty reading signs while walking

• Dizziness and disorientation

• Balance problems

• Trouble focusing on faces during conversation

Common causes of VOR dysfunction:

• Concussion or traumatic brain injury

• Vestibular neuritis (inner ear infection)

• Aging

• Certain medications

• Inner ear damage

Can the VOR be improved?
Yes. VOR exercises (also called gaze stabilization exercises) can help retrain this reflex. The brain has significant plasticity and can adapt to improve VOR function, even after injury. Most people see improvement within 4-8 weeks of consistent practice.

VOR exercises can be done at home with minimal equipment. Here's how to perform the most common types:

VOR x1 Exercises (Basic)

• 1. Hold a target (letter, business card, or your thumb) at arm's length

• 2. Focus on the target and keep it clear

• 3. Turn your head side to side while keeping eyes fixed on the target

• 4. Start slowly (1-2 seconds per direction)

• 5. Gradually increase speed as tolerated

• 6. Do for 1-2 minutes, 3-5 times daily

VOR x2 Exercises (Advanced)

• 1. Hold a target at arm's length

• 2. Move your head AND the target in opposite directions

• 3. Head goes left, target goes right (and vice versa)

• 4. Keep the target in focus the entire time

• 5. Do for 1-2 minutes, 3-5 times daily

Key principles:

• The target should stay clear. If it blurs, slow down.

• Some dizziness during exercises is normal and expected

• If dizziness is severe (7+/10), reduce speed or duration

• Progress gradually: speed, then duration, then complexity

Progression steps:

• 1. Sitting → Standing → Walking

• 2. Eyes level → Eyes looking up → Eyes looking down

• 3. Solid floor → Foam pad → Eyes closed

Common mistakes to avoid:

• Moving only your eyes (your head must move)

• Going too fast before the brain adapts

• Stopping because of mild dizziness (this is actually beneficial)

• Not practicing consistently

Apps like VOR Eye Rehab provide guided exercises with proper pacing and progression tracking.

For best results, VOR exercises should be done 3-5 times daily for 1-2 minutes per session. Consistency matters more than duration.

Recommended schedule:

Frequency: 3-5 times per day
Duration: 1-2 minutes per session (not longer)
Total daily time: 5-10 minutes spread throughout the day

Why short, frequent sessions work best:

• The vestibular system fatigues quickly

• Longer sessions lead to diminishing returns

• Multiple short sessions create more learning opportunities

• Easier to fit into daily life = better compliance

Sample daily schedule:

• Morning: 2 minutes after waking

• Mid-morning: 2 minutes during work break

• Afternoon: 2 minutes after lunch

• Evening: 2 minutes before dinner

• Night: 2 minutes before bed

How long until results:

• Week 1-2: May initially feel worse (adaptation phase)

• Week 3-4: Most people notice improvement

• Week 6-8: Significant improvement

• Week 12: Maximum benefit for most people

Signs you're ready to progress:

• Current level causes minimal dizziness (<3/10)

• You can maintain clear vision throughout

• You've been at this level for 1-2 weeks

When to reduce frequency:

• After 8-12 weeks of consistent improvement

• Maintenance: 1-2 times daily is often sufficient

The key is daily practice. Missing several days can slow progress significantly.

Balance is maintained by three systems working together: the vestibular system (inner ear), vision, and proprioception (body position sensors).

The Three Balance Systems:

1. Vestibular System (Inner Ear) - ~60% of balance

• Location: Inner ear on each side

• Components: Semicircular canals (detect rotation) and otolith organs (detect linear motion/gravity)

• Detects: Head position and movement

• Sends info to: Brain stem, eyes (VOR), and spine

2. Vision - ~20% of balance

• Provides: Spatial orientation reference

• Tells you: Where you are relative to your environment

• Works with: Vestibular system for stable vision (VOR)

3. Proprioception - ~20% of balance

• Sensors in: Joints, muscles, tendons, skin (especially feet)

• Detects: Body position, joint angles, surface contact

• Important for: Standing on uneven surfaces, walking in the dark

How they work together:

• Your brain constantly compares input from all three systems

• If signals conflict, you may feel dizzy or off-balance

• If one system is damaged, the others can compensate (with training)

Why balance problems occur:

• Vestibular damage (concussion, infection, aging)

• Visual problems

• Peripheral neuropathy (reduced sensation in feet)

• Muscle weakness

• Central nervous system disorders

Can balance be improved?
Yes! Balance can be trained at any age. Vestibular rehabilitation exercises help the brain better integrate information from all three systems and compensate for deficits.

Balance improves through progressive exercises that challenge the vestibular system, vision, and proprioception. Here's a structured approach:

Beginner Balance Exercises:

• 1. Feet together stand: 30-60 seconds

• 2. Semi-tandem stance: One foot slightly ahead, 30 seconds each side

• 3. Single leg stand: Hold onto something if needed, 30 seconds each leg

• 4. Weight shifts: Rock side-to-side and front-to-back

• 5. Heel-to-toe walking: 10 steps forward and back

Intermediate Exercises:

• 1. Single leg stand with eyes closed: 15-30 seconds

• 2. Standing on foam pad: Progress through all stances

• 3. Tandem stance (heel-to-toe): 30 seconds

• 4. Walking with head turns: Turn head side-to-side while walking

• 5. Stepping over obstacles: Walk over small objects

Advanced Exercises:

• 1. Single leg stand on foam with eyes closed

• 2. Walking on various surfaces: Grass, sand, uneven ground

• 3. Tai Chi or yoga movements

• 4. Sport-specific balance drills

• 5. Reactive balance training: Catching balls while standing

Key Principles:

• Practice 10-15 minutes daily

• Progress when current level feels easy

• Challenge yourself safely (near a wall or counter)

• Reduce visual input (eyes closed) to challenge vestibular system

• Use unstable surfaces (foam, wobble boards) to increase difficulty

Sample progression:
Week 1-2: Beginner on solid floor
Week 3-4: Beginner on foam + Intermediate on solid floor
Week 5-6: Intermediate on foam + some Advanced
Week 7+: Advanced exercises, maintain with variety

Most people see significant improvement in 6-8 weeks of consistent practice.

Balance exercises for seniors should be safe, progressive, and focused on preventing falls. Here are the most effective exercises for older adults:

Safety First:

• Always exercise near a sturdy surface (counter, chair back, wall)

• Wear supportive, non-slip footwear

• Clear the area of tripping hazards

• Have someone nearby when starting

Recommended Exercises:

Level 1: Supported Standing

• 1. Countertop marching: March in place holding the counter

• 2. Side leg raises: Hold counter, lift leg to side, 10 each leg

• 3. Heel raises: Hold counter, rise onto toes, 10-15 reps

• 4. Hip circles: Small circles with hips, both directions

Level 2: Light Support

• 1. Semi-tandem stand: One hand on counter, 30 seconds each side

• 2. Clock reach: Stand on one leg, reach to different "clock positions"

• 3. Heel-toe rocking: Rock from heels to toes

• 4. Weight shifts: Shift weight side to side

Level 3: Minimal Support

• 1. Single leg stand: Fingertip touch on counter only, 30 seconds

• 2. Tandem walking: Walk heel-to-toe along a line

• 3. Sit-to-stand without hands: Use legs only (if able)

• 4. Walking with head turns: Turn head while walking

How often:

• 10-15 minutes daily (or at least 3x/week)

• 2-3 sets of each exercise

• Progress every 2-4 weeks

Additional recommendations:

• Tai Chi: Proven to reduce falls by 20-40%

• Walking: 30 minutes most days

• Strength training: Leg strength is crucial for balance

• Vision: Keep glasses prescription current

Falls are the leading cause of injury in adults over 65. Regular balance exercise is one of the most effective preventive measures.

Brain fog after concussion is treatable with the right strategies. Here's a comprehensive approach:

Understanding brain fog:

• Difficulty concentrating

• Slower thinking

• Memory problems

• Mental fatigue

• Difficulty finding words

Immediate strategies:

Energy management:

• Break tasks into 15-30 minute chunks

• Take regular breaks (5-10 minutes per hour)

• Schedule demanding tasks when you're most alert

• Don't push through fatigue—it makes it worse

Environment optimization:

• Reduce background noise

• Work in well-lit (but not harsh) spaces

• Minimize visual clutter

• Use noise-canceling headphones if needed

Cognitive supports:

• Use lists and written reminders

• Set phone alarms for important tasks

• Use a single notebook for notes (not scattered papers)

• Take notes during conversations

• Repeat back instructions to confirm understanding

Physical health:

• Sleep 8-10 hours (crucial for brain healing)

• Stay hydrated

• Eat regular, balanced meals

• Engage in light aerobic exercise (as tolerated)

What helps long-term:

• 1. Aerobic exercise: Increases blood flow to brain

• 2. Cognitive rehabilitation: Structured exercises to rebuild skills

• 3. Good sleep hygiene: Essential for brain recovery

• 4. Stress management: Stress worsens cognitive symptoms

Timeline:

• Most cognitive symptoms improve within 1-3 months

• If brain fog persists beyond 3 months, seek evaluation

• Speech-language pathologists specialize in cognitive rehabilitation

Brain fog improves with time and appropriate rest. Trying to power through typically prolongs recovery.

Light sensitivity (photophobia) is common after concussion and can be managed with proper strategies while the brain heals.

Why it happens:

• The brain has difficulty processing visual information

• Pathways between eyes and brain are stressed

• Often linked to migraine-like mechanisms

Immediate management:

Lighting adjustments:

• Use dimmer switches at home

• Replace harsh overhead lights with lamps

• Use warm-colored bulbs (2700K or lower)

• Close blinds during bright parts of the day

• Wear a hat with a brim outdoors

Screen modifications:

• Reduce screen brightness to 50% or lower

• Enable dark mode on all devices

• Use blue light filters (Night Shift, f.lux)

• Increase text size to reduce eye strain

• Reduce screen time duration

Eyewear options:

• FL-41 tinted lenses (rose-colored, specifically for light sensitivity)

• Regular sunglasses outdoors

• Avoid very dark sunglasses indoors (can increase sensitivity over time)

• Transition lenses for variable lighting

Important principle:

• Gradual light exposure helps recovery (avoid complete darkness)

• Progressively increase light tolerance

• Start with 10-15 minutes in brighter light, gradually increase

When to get help:

• If sensitivity persists beyond 4-6 weeks

• If it's severely limiting daily activities

• If accompanied by visual symptoms (blurring, double vision)

Specialists who can help:

• Neuro-ophthalmologist

• Optometrist specializing in vision therapy

• Concussion clinic

Most light sensitivity improves within 2-8 weeks. Complete avoidance of light can prolong sensitivity, so gradual exposure is key.

Post-concussion headaches affect up to 90% of concussion patients initially and can persist in some. Here's how to manage them:

Types of post-concussion headaches:

1. Migraine-type (most common)

• Throbbing, often one-sided

• Light and sound sensitivity

• Nausea

• Made worse by activity

• Treatment: Migraine medications, prevention strategies

2. Tension-type

• Pressing, band-like sensation

• Both sides of head

• Mild-moderate intensity

• Often related to neck tension

• Treatment: Physical therapy, stress management

3. Cervicogenic (neck-related)

• Starts in neck, radiates to head

• Associated with neck injury

• Made worse by neck positions

• Treatment: Physical therapy, manual therapy

4. Rebound headaches

• From overuse of pain medication

• Occurs if taking pain meds more than 2-3x/week

• Treatment: Medication reduction under medical guidance

Immediate relief strategies:

• Ice or heat to neck and base of skull

• Rest in a dark, quiet room

• Stay hydrated

• Gentle neck stretches

• Peppermint oil on temples

Prevention strategies:

• Maintain regular sleep schedule

• Don't skip meals

• Stay hydrated (8+ glasses water daily)

• Limit caffeine to morning only

• Pace activities to avoid overexertion

• Regular aerobic exercise (once tolerated)

When to use medication:

• Limit OTC pain meds to 2-3 days per week max

• Consider preventive medications if headaches are frequent

• Discuss options with your doctor

When to seek help:

• Headaches worsening over time

• Not responding to over-the-counter treatment

• Interfering significantly with daily life

• Accompanied by neurological symptoms

A headache specialist or concussion clinic can help identify the headache type and create a targeted treatment plan.

A vestibular therapist (a specially trained physical or occupational therapist) can be very helpful for dizziness and balance problems, but not everyone needs one.

You likely need a vestibular therapist if:

• Dizziness lasting more than 2-4 weeks after concussion

• Balance problems affecting daily activities

• Difficulty with head movements (turning to look around)

• Motion sensitivity (cars, scrolling, crowds)

• BPPV that hasn't resolved with basic maneuvers

• Falling or fear of falling

• Visual problems related to head movement

You may be able to self-manage if:

• Symptoms are mild and improving

• You can tolerate basic VOR exercises

• No significant balance problems

• Responding well to home exercises (like those in apps)

What a vestibular therapist does:

• 1. Assessment: Identifies specific vestibular deficits

• 2. Diagnosis: Confirms or rules out conditions like BPPV

• 3. Customized treatment plan: Exercises matched to your specific issues

• 4. Manual techniques: Hands-on treatment when needed

• 5. Progression guidance: Knows when and how to advance exercises

• 6. Monitoring: Tracks progress and adjusts treatment

What to expect:

• Initial evaluation: 45-60 minutes

• Treatment sessions: 30-60 minutes, 1-2x/week

• Duration: 4-12 weeks typically

• Home exercises: 15-20 minutes daily

How to find one:

• Ask your doctor for a referral

• Search vestibular.org for certified providers

• Look for "vestibular rehabilitation" or "concussion" specialty

• Check credentials: PT or OT with vestibular certification

Most insurance covers vestibular therapy with a referral. The combination of professional guidance and consistent home exercise produces the best outcomes.

Many people can successfully do vestibular rehabilitation at home, but some situations require professional guidance.

Home-based rehab works well for:

• Mild-moderate symptoms

• Straightforward vestibular hypofunction

• People who are motivated and consistent

• Those with access to good quality guidance (apps, videos)

• Follow-up with a doctor for monitoring

You should see a professional if:

• Symptoms are severe (7+/10)

• You have BPPV (needs proper diagnosis and maneuvers)

• You're not sure what exercises to do

• Symptoms aren't improving after 4-6 weeks

• You have additional injuries (neck, vision problems)

• History of multiple concussions

• You're falling or at high fall risk

• You feel unsafe exercising alone

The case for professional help:

• Accurate diagnosis (determines treatment approach)

• Customized exercise prescription

• Hands-on treatment when needed

• Faster progress with expert guidance

• Accountability and motivation

• Can identify complicating factors

The case for home-based:

• More convenient and accessible

• Lower cost

• Exercises can be done more frequently

• Good apps provide structured progression

• Works well for motivated individuals

Optimal approach for most people:

• 1. Start with home exercises using a quality app

• 2. If not improving in 4-6 weeks, see a professional

• 3. Professional sets you up with customized program

• 4. Continue with app/home exercises between appointments

• 5. Return to professional if needed

Using apps like VOR Eye Rehab:

• Provides structured exercise protocols

• Guides progression based on symptoms

• Tracks your progress over time

• Good option for mild-moderate symptoms

• Best when combined with medical oversight

The best outcomes combine professional evaluation with consistent home practice.

Medication can help manage dizziness symptoms, but it's usually not the primary treatment. Here's what to know:

Medications that may help:

For acute vertigo (short-term use only):

• Meclizine (Antivert): Reduces spinning sensation

• Dimenhydrinate (Dramamine): For motion sickness component

• Ondansetron (Zofran): For severe nausea

• Benzodiazepines: For severe acute vertigo (ER use)

For vestibular migraine:

• Preventive: Beta-blockers, topiramate, amitriptyline

• Acute: Triptans if migraine headache present

For Meniere's disease:

• Diuretics: Reduce inner ear fluid

• Betahistine: Used in some countries

Important cautions:

Vestibular suppressants (meclizine, etc.):

• Should only be used short-term (days, not weeks)

• Long-term use slows recovery

• They prevent the brain from adapting

• May be appropriate during severe acute episodes only

Why medication isn't the main treatment:

• 1. Dizziness often responds better to rehabilitation

• 2. Suppressants can delay vestibular compensation

• 3. They treat symptoms, not underlying cause

• 4. Side effects include drowsiness, cognitive slowing

When medication is appropriate:

• Severe acute vertigo episodes

• Vestibular migraine prevention

• Meniere's disease management

• Bridge therapy while starting rehabilitation

Better long-term strategies:

• Vestibular rehabilitation exercises

• Lifestyle modifications

• Treating underlying conditions

• Gradual exposure to triggers

Bottom line:
Talk to your doctor before taking dizziness medication regularly. For most vestibular problems, exercises are more effective than medication, and medication can actually slow recovery if used long-term.
