A blow to the head, a fall, a sports injury, or a car accident can cause a concussion, even without loss of consciousness. Treatment for a mild concussion in adults does not involve simply “toughing it out” and waiting for it to pass. It is based on an appropriate evaluation, a short period of relative rest, and a gradual return to activities depending on how symptoms progress.
A concussion is a brain injury caused by a sudden movement of the head or body. Symptoms may appear immediately or develop within the following hours. Headaches, a foggy feeling, unusual fatigue, nausea, dizziness, sensitivity to noise or light, difficulty concentrating, and irritability are common. The intensity of these symptoms does not always reflect the severity of the injury; therefore, even an injury that seems minor deserves serious attention.
The First Few Hours: Protecting Yourself Without Isolating Yourself
After a head injury, a medical evaluation is recommended, especially if symptoms persist, worsen, or if the accident was severe. A doctor or specialized nurse practitioner can assess your neurological status, rule out any complications, and provide guidance tailored to your situation.
During the first 24 to 48 hours, focus on getting some rest. This means avoiding activities that significantly worsen your symptoms, without staying in bed in the dark for several days. Screen time, prolonged reading, demanding meetings, intense physical exertion, and noisy environments can be temporarily limited. However, short, quiet activities at home, simple trips around the house, and regular sleep are generally preferable to complete inactivity.
Avoid alcohol, recreational drugs, and activities that pose a risk of another fall or head injury. You should also refrain from driving as long as you experience dizziness, visual disturbances, slowed reaction time, or difficulty concentrating. To relieve pain, consult a healthcare professional. Acetaminophen, also known as paracetamol, may sometimes be considered, while certain anti-inflammatory medications are not always appropriate immediately after an injury.
Signs That Require Urgent Care
Most mild concussions resolve on their own, but certain symptoms may indicate a more serious condition. Contact the emergency room immediately if the person exhibits any of the following signs:
- loss of consciousness, difficulty staying awake, or worsening confusion;
- repeated vomiting, a seizure, or a headache that suddenly gets much worse;
- weakness, numbness, or problems with speech, balance, or vision;
- unusual behavior, marked agitation, or one pupil that is larger than the other.
An urgent medical evaluation is also necessary following an injury for anyone taking anticoagulants, suffering from a bleeding disorder, or who had consumed a large amount of alcohol at the time of the accident. If in doubt, it is best to have the situation assessed promptly.
Treatment of a Mild Concussion in Adults: A Gradual Return to Normal Activities
After the initial phase, the goal is not to eliminate all activity, but to gradually return to your usual level of activity without causing a lasting worsening of symptoms. A slight, temporary increase in symptoms may occur during physical exertion. It should remain moderate and return to its initial level after a short rest. If the increase is severe or persistent, the activity was too strenuous and must be adjusted.
Rehabilitation often begins with short walks at a comfortable pace, followed by simple daily activities. Light cardiovascular exercise can be reintroduced if symptoms allow—such as using a stationary bike, brisk walking, or gentle exercises. Sports that involve a risk of contact, falls, or blows to the head should be postponed until authorized by a qualified professional.
The same principle applies to cognitive activities. Catching up on a few emails, doing some light reading, or tackling a simple administrative task can be helpful, as long as you take breaks. Then gradually increase the duration and complexity based on your tolerance. Trying to catch up on several days’ worth of work all at once is often counterproductive.
The pace of recovery varies. Many adults notice a marked improvement within a few days to a few weeks. However, a history of concussions, migraines, anxiety disorders, sleep disturbances, neck injuries, or high-stress situations can slow down recovery. This is neither a lack of willpower nor a cause for alarm; above all, it indicates that more personalized care may be necessary.
The Role of Physical Therapy and Rehabilitation
A concussion doesn’t just affect the brain. After an impact, the neck, the vestibular system (which controls balance), and eye movements can also contribute to symptoms. Dizziness when turning the head, discomfort in stores, blurred vision while reading, neck pain, or movement-induced headaches are useful symptoms to report during the evaluation.
Physical therapy may be recommended when symptoms persist or limit a person’s ability to resume activities. The physical therapist assesses, among other things, neck mobility, balance, exercise tolerance, eye-head coordination, and the factors that trigger symptoms. Treatment may include progressive exercises for balance, cervical mobility, vestibular rehabilitation, or gaze stabilization. The goal is not to push through symptoms, but to expose the system to gradual challenges to promote adaptation.
Depending on the needs, a multidisciplinary approach may be appropriate. Occupational therapy can help organize a return to work and manage cognitive tasks. Kinesiology can guide a safe progression in physical activity. A primary assessment helps coordinate care and determine whether additional tests or a medical consultation are needed. In a network like Physio Multiservices, this complementary approach facilitates referral to the appropriate professional.
Returning to Work: It’s Better to Adapt Than to Take Time Off Without a Plan
Returning to work after a mild concussion depends on the job, the symptoms, and the level of risk. Working at a computer in a quiet environment does not present the same challenges as a job as a driver, a material handler, a worker at heights, or someone working in a very noisy environment.
Temporary accommodations can make a big difference: shorter work hours, scheduled breaks, reducing multitasking, a quieter environment, adjusted lighting, or a gradual return to responsibilities. The employer does not need to know all the medical details to support a return to work. A healthcare professional can provide specific recommendations regarding temporary limitations.
Do not return to work that involves a risk of falling, collision, or a blow to the head until your attention, balance, and reaction time have returned to normal. A second concussion before you have fully recovered can lead to a longer recovery period and more complications.
When should you schedule a follow-up appointment, even if it’s not an emergency?
Make an appointment if your symptoms don’t improve after a few days, if they prevent you from working, sleeping, or driving, or if they return as soon as you slightly increase your activity level. You should also see a doctor if headaches, neck pain, dizziness, or vision problems become the main obstacle to your recovery.
Recovering from a concussion sometimes means taking it slow, but it shouldn’t leave you feeling uncertain. A clear plan, tailored to your symptoms and daily life, helps you regain confidence in your movements, your work, and your activities—one step at a time.
