How Common Are Headaches After Brain Injury?

Headaches are among the most frequently reported symptoms after:

Concussion
Mild traumatic brain injury (mTBI)
Moderate and severe TBI
Repeated head trauma
Post-Concussion Syndrome (PCS)

Many people experience headaches in the days and weeks following injury, while others continue to experience them months or years later.

When Should You Seek Medical Advice?

You should seek medical advice if:

Headaches are new or worsening
Headaches significantly affect daily life
Symptoms suddenly change
You experience new neurological symptoms
Headaches are interfering with sleep or functioning

It is important not to assume every headache is simply related to a previous brain injury.

Why Do Headaches Happen After Brain Injury?

There is rarely one single cause.

In many cases, headaches result from a combination of factors.

Understanding potential causes can help guide treatment and management.

Changes Within the Brain

Following an injury, the brain undergoes a complex healing process.

This may involve:

Changes in blood flow
Neuroinflammation
Altered nerve signalling
Increased sensitivity to stimulation

These changes can contribute to headaches and migraines.

Neck Injuries

Many brain injuries occur alongside injuries to the neck.

Whiplash and neck strain are particularly common following:

Falls
Sporting injuries
Road traffic collisions

Problems within the muscles, joints, and nerves of the neck can cause:

Headaches
Migraines
Dizziness
Visual disturbances

Sometimes the neck is contributing more to symptoms than people realise.

Sensory Overload

The injured brain often struggles to filter sensory information.

Exposure to:

Bright lights
Loud noises
Crowds
Busy environments

can trigger or worsen headaches.

Fatigue

Neuro fatigue and headaches often go hand in hand.

As the brain becomes tired, headaches frequently become worse.

Many people notice headaches increase later in the day when energy reserves are running low.

Sleep Problems

Poor sleep is one of the biggest headache triggers.

Common sleep difficulties after brain injury include:

Insomnia
Sleep apnoea
Frequent waking
Poor-quality sleep
REM sleep disorders

Poor sleep can make headaches more frequent and more severe.

Stress and Emotional Strain

Living with a brain injury can be stressful.

Stress, anxiety, grief, frustration, and emotional overload can all contribute to headaches.

This does not mean the headaches are "psychological."

It simply reflects the close relationship between the brain, nervous system, and stress response.

Common Types of Headaches After Brain Injury

Tension-Type Headaches

Often described as:

Tightness around the head
Pressure
A band-like sensation

These headaches are commonly linked to:

Muscle tension
Stress
Fatigue
Neck problems

Migraine

Migraines are common after brain injury.

Symptoms may include:

Moderate to severe pain
Throbbing sensations
Light sensitivity
Noise sensitivity
Nausea
Visual disturbances

Not all migraines involve a severe headache.

Some people experience migraine symptoms without significant pain.

Cervicogenic Headaches

These headaches originate from the neck.

Symptoms may include:

Pain starting at the base of the skull
Neck stiffness
Pain radiating behind the eyes
Headaches triggered by neck movement

Exertion Headaches

These headaches may occur following:

Physical activity
Mental effort
Concentration
Social interaction

Many people notice headaches after activities that increase cognitive load.

Medication Overuse Headaches

Sometimes frequent use of pain relief medication can actually contribute to ongoing headaches.

This is known as medication overuse headache.

If you are relying heavily on pain medication, discuss this with your healthcare provider.

Keeping a Headache Diary

One of the most useful tools for many people is a headache diary.

Track:

When headaches occur
Severity
Sleep quality
Stress levels
Food and drink
Activity levels
Potential triggers

Patterns often become easier to identify over time.

Medical Treatments

Treatment depends on the type of headache and individual circumstances.

Potential options may include:

Pain relief medications
Migraine-specific medications
Preventative migraine medications
Treatment for sleep disorders
Treatment for neck problems
Management of underlying health conditions

Always discuss medication options with a qualified healthcare professional.

A Message of Hope

Living with headaches or migraines after a brain injury can be frustrating and exhausting.

Some days may feel overwhelming.

But many people find that understanding their triggers, improving sleep, managing fatigue, and finding the right combination of treatments significantly improves their quality of life.

Recovery is rarely about finding one magic solution.

More often, it involves building a toolkit of strategies that work for you.

Progress may be gradual, but it is possible.

Rehabilitation Approaches

Depending on the cause of the headaches, healthcare professionals may recommend:

Physiotherapy

Particularly if neck problems are contributing.

Vestibular Rehabilitation

If dizziness and balance issues are involved.

Vision Therapy

If visual problems are triggering symptoms.

Occupational Therapy

To help manage fatigue and pacing.

Psychological Support

To help manage stress, anxiety, and the emotional impact of chronic symptoms.

Self-Help Strategies

Gentle Physical Activity

For many people, gentle exercise may help support:

Blood flow
Sleep
Mood

Stress management

Activities such as walking, swimming, or yoga may be beneficial if tolerated.

Manage Stress

Helpful techniques may include:

Mindfulness
Breathing exercises
Meditation
Counselling
Spending time in nature

Review Alcohol and Caffeine Intake

Both alcohol and excessive caffeine may trigger headaches in some individuals.

Understanding your own triggers is important.

Many people find that a combination of small changes can significantly reduce headache frequency and severity.

Prioritise Sleep

Sleep is one of the most important factors in headache management.

Aim for:

Consistent bedtimes
Consistent wake times
Good sleep hygiene

If you suspect sleep apnoea or another sleep disorder, seek medical advice.

Stay Hydrated

Dehydration is a common headache trigger.

Many people simply do not drink enough water throughout the day.

Don't Skip Meals

Low blood sugar can trigger headaches and migraines.

Regular, balanced meals may help.

Manage Fatigue

Fatigue is a major headache trigger.

Strategies such as:

Pacing
Rest breaks
Energy management

can help reduce symptom flare-ups.

Reduce Sensory Overload

Consider:

Sunglasses
Noise-cancelling headphones
Taking breaks from busy environments

when symptoms begin building.
