A\u00a0concussion<\/b>\u00a0is one of the most common injuries affecting the brain, often described as a\u00a0mild traumatic brain injury<\/i>. Yet, despite this qualifier, its consequences can be very real and lasting. Whether following an\u00a0impact during sports activity<\/b>, a\u00a0car accident<\/b>, a\u00a0fall<\/b>\u00a0or even a\u00a0minor impact<\/b>, a concussion can temporarily disrupt brain function.\u00a0Symptoms vary depending on the severity, the area of the brain affected and the person themselves. Some appear immediately, others several hours or even days after the trauma. Recognizing these signs is crucial to react in time, avoid complications and allow for complete recovery.<\/p>\n1. What is a concussion?<\/b><\/h2>\n
A concussion occurs when the\u00a0brain undergoes rapid and violent movement<\/b>\u00a0inside the skull. This sudden movement causes a\u00a0disruption of neuronal function<\/b>, without necessarily causing structural damage visible on medical imaging (MRI or CT scan).\u00a0In other words, the brain is not “broken,” but\u00a0unbalanced in its internal communication<\/b>. The neurons, synaptic connections and electrical circuits are temporarily altered.<\/p>\n Even an\u00a0impact without loss of consciousness<\/b>\u00a0can cause a concussion.<\/p>\n Physical symptoms often appear\u00a0in the first hours<\/b>\u00a0following impact, but may also worsen within 24 to 48 hours.<\/p>\n This is the most common sign. The pain can be diffuse or localized, pulsating or constant. It often worsens during exertion, exposure to light or prolonged concentration.<\/p>\n Many patients describe a sensation of vertigo, as if “the room is spinning.” This is explained by a disruption of connections between the brain and the vestibular system (inner ear).<\/p>\n These occur due to irritation of the brainstem or disruption of sensory signals.<\/p>\n A concussion can temporarily alter oculomotor coordination, causing blurred vision, difficulty reading or focusing on an object.<\/p>\n Photophobia (light intolerance) and phonophobia (noise intolerance) are common, as the brain becomes hypersensitive to sensory stimuli.<\/p>\n A concussion does not only affect the body, but also\u00a0mental and cognitive abilities<\/b>. These symptoms are often more subtle, but just as important to recognize.<\/p>\n The brain struggles to filter and process information. Looking at a screen, reading or following a conversation becomes exhausting.<\/p>\n The patient may forget what happened before or after the impact. Sometimes, they no longer remember a few minutes or hours of the event (post-traumatic amnesia<\/i>).<\/p>\n Simple intellectual tasks take longer. This is described as a feeling of “brain fog,” where thoughts seem confused or slowed.<\/p>\n The person may seem distracted, elsewhere, with difficulties following the thread of a discussion.<\/p>\n The brain also manages emotions. When it is disrupted, mood changes can appear, sometimes without the person being aware of them.<\/p>\n The patient becomes more irritable or reacts excessively to mundane situations.<\/p>\n Emotions can be amplified: persistent anxiety, frequent crying or feelings of dejection.<\/p>\n Some people feel “different,” more withdrawn or less motivated than before.<\/p>\n Regulating emotions requires energy, and the concussed brain tires more quickly. This can lead to great psychological weariness.<\/p>\n Sleep is often disrupted after a concussion:<\/p>\n These disorders directly influence recovery, as sleep is essential for neuronal repair.<\/p>\n Some symptoms only appear later, sometimes up to two weeks after the impact. This is called\u00a0post-concussion syndrome<\/b>.\u00a0These signs can include:<\/p>\n It is therefore crucial to\u00a0monitor the progression of symptoms<\/b>\u00a0and consult a professional if they persist beyond a few days.<\/p>\n A concussion requires\u00a0rapid medical assessment<\/b>, even if symptoms seem minor. You should\u00a0go to the emergency room immediately<\/b>\u00a0if you observe:<\/p>\n Follow-up by a\u00a0neuropsychologist or cognitive rehabilitation specialist<\/b>\u00a0is often recommended to assess the extent of cognitive and emotional effects.<\/p>\n Symptoms can be more difficult to identify. A concussed child often becomes\u00a0irritable, apathetic or cries more than usual<\/b>. Sleep and appetite problems are also warning signals.<\/p>\n Cognitive and visual problems can impair work performance, especially in occupations requiring concentration or precision.<\/p>\n Recovery is often slower, as the ageing brain functions less efficiently. Moreover, the risks of neurological complications are higher.<\/p>\n Health professionals use various tools to assess the patient’s cognitive and physical state:<\/p>\n This comprehensive approach helps determine the severity of the concussion and plan appropriate rehabilitation.<\/p>\n Located in Quebec,\u00a0Neurodezign<\/b>\u00a0is a clinic specializing in\u00a0neuropsychology and cognitive rehabilitation<\/b>. It is distinguished by a comprehensive approach combining\u00a0assessment, remediation and optimization of brain performance<\/b>.\u00a0Its team works with\u00a0children, adolescents and adults<\/b>\u00a0presenting cognitive, motor or emotional disorders, particularly following a\u00a0concussion<\/b>.<\/p>\n Neurodezign combines\u00a0conventional<\/b>\u00a0tools such as neuropsychological assessment with\u00a0modern<\/b>\u00a0techniques such as:<\/p>\n Through this personalized approach, Neurodezign helps the brain\u00a0regain functional balance<\/b>. Patients benefit from customized support aimed at:<\/p>\n Neurodezign thus offers a\u00a0bridge between science and rehabilitation<\/b>, giving each individual the full potential of their brain capacities.<\/p>\n The symptoms of a concussion can be\u00a0physical, cognitive, emotional or sensory<\/b>, and their intensity varies from person to person. What seems to be a simple headache or passing fatigue may actually reflect a temporary neurological imbalance.\u00a0Quickly recognizing the signs, consulting a professional and following an appropriate rehabilitation program are the keys to\u00a0complete recovery<\/b>.\u00a0With the support of specialists like those at\u00a0Neurodezign<\/b>, recovery is not limited to the disappearance of symptoms, but aims to\u00a0restore full brain performance<\/b>: an essential step to regain concentration, emotional balance and quality of life.<\/p>\n","protected":false},"excerpt":{"rendered":" Concussion symptoms range from physical to cognitive and emotional.
