A neurologist has shared five 'tell-tale' signs of a concussion that you need to look out for.

Concussions might be a relatively common injury but they aren't always the easiest to identify. 

From mood changes to visual disturbances, the injury can be identified by multiple characteristics.

Consultant Neurologist at Re:Cognition Health, Dr Steve Allder, has shared several symptoms to look out for that could indicate a concussion.

What are 5 signs and symptoms of a concussion?

Mood and behaviour changes

The neurologist has explained that it is actually relatively common for someone who has suffered a head injury to experience changes in their mood.

"Concussions can affect the brain's ability to regulate emotions, leading to irritability, depression, anxiety, or other mood changes," Dr Allder added.

"Watch for sudden changes in behaviour or personality that seem out of character."

Visual disturbances

Concussions have also been known to impact people's vision, the Doctor continued.

"Concussions can cause blurred vision, double vision, or other visual disturbances, such as difficulty focusing or tracking objects," the expert commented.

"These symptoms may not always be obvious and may occur days or weeks after the injury."

Balance problems

People who have suffered a concussion often have trouble with their balance afterwards.

Dr Allder explained: "Dizziness, unsteadiness, or difficulty maintaining balance are common signs of concussion.

"Pay attention to any changes in gait or balance, especially if they occur without an obvious cause."

Cognitive difficulties

We can also experience problems with our memory and concentration after sustaining a concussion.

Concussions are known to cause memory impairments as well as general brain fog, the neurologist said.

"Concussions can cause problems with memory, concentration, and other cognitive functions," the expert added.

"This may manifest as forgetfulness, difficulty following conversations, or feeling mentally foggy."

Sleep disturbances

Finally, concussions can also lead to disturbances in your sleep cycle.

"Concussions can disrupt sleep patterns, leading to insomnia, excessive sleepiness, or other sleep disturbances," the expert continued.

"Be alert for changes in sleep patterns, such as difficulty falling or staying asleep, or sleeping more than usual."

If you are experiencing any symptoms that you think could be linked to a concussion or any other head injury, it is vital that you speak to a medical professional.

How long does a concussion last?

Approximately 80% of concussions resolve over seven to 14 days, with an average of 10 day, according to the experts at Beaumont Health.

However, its website advises that people with concussions should never return to sports or other physical activity sooner than one week after they have sustained the injury.

Depending on how severe the injury is, a concussed patient has to go through two and sometimes three phases before a full recovery.
