What is a concussion?
A concussion is a type of traumatic brain injury (TBI) caused by a bump, blow, or jolt to the head or body that causes the brain to move rapidly inside the skull. This sudden movement can create chemical changes in the brain and sometimes stretch and damage brain cells. The effects can be temporary but can cause significant disruptions in cognitive functions, balance, and coordination.
Immediate signs of concussion to watch for

After a head injury, immediate symptoms of a concussion might appear. According to a study published in the ‘Journal of Athletic Training,’ these symptoms can include:
Headache: One of the most common symptoms.
Confusion: The injured person might seem dazed or have trouble answering questions.
Amnesia: Difficulty remembering events before or after the injury.
Dizziness and balance issues: Trouble with balance or coordination.
Nausea or vomiting: Feeling sick or actually vomiting can occur soon after the impact.
Delayed symptoms of concussion to be aware of
Symptoms of a concussion can also develop hours or days after the initial injury.
Sensitivity to light and noise: The individual might find bright lights or loud noises particularly bothersome.
Sleep disturbances: Difficulty falling asleep or sleeping more than usual.
Mood changes: Increased irritability, sadness, or nervousness.
Cognitive problems: Difficulty concentrating or remembering things.
Physical symptoms: Persistent headaches, blurred vision, and fatigue.
Behavioural and emotional changes
Changes in behaviour and emotions can be subtle but are important indicators of a concussion. A study by the ‘American Journal of Sports Medicine’ highlights that concussions can lead to noticeable changes in mood and behaviour, such as:
Irritability: Increased frustration over small issues.
Depression: Feeling sad or hopeless without a clear reason.
Anxiety: Sudden onset of nervousness or anxiety.
Personality changes: Acting differently than usual, more withdrawn, or more aggressive.
Recognising concussions in children
Children might not be able to articulate their symptoms as clearly as adults. The CDC emphasises watching for signs such as:
Changes in play: Less interest in favorite toys or activities.
Clumsiness: More frequent falls or trouble walking.
Tiredness: Unusual sleepiness or lethargy.
Crying: Excessive crying without an obvious reason.
Changes in eating or sleeping habits: Unexplained changes in appetite or sleep patterns.
It is essential to seek medical attention if a concussion is suspected. The National Institute of Neurological Disorders and Stroke advises immediate medical evaluation if the person:
Loses consciousness: Even briefly.
Has repeated vomiting: This can indicate a more severe injury.
Experiences seizures: Seizures are a sign of severe brain trauma.
Exhibits worsening symptoms: Increasing headaches, confusion, or unusual behaviour.
