What happens when you have concussion?

A concussion is a type of traumatic brain injury (TBI) that can affect brain function. It is usually caused by a blow to the head, but can also be caused by a sudden deceleration or acceleration of the head.

When a person experiences a concussion, the brain is shaken inside the skull. This can cause damage to brain cells, blood vessels, and nerves.

Concussions can cause a wide range of symptoms, including:

* Headache

* Nausea and vomiting

* Confusion

* Disorientation

* Memory loss

* Slurred speech

* Problems with balance and coordination

* Vision changes

* Sensitivity to light and noise

* Fatigue

* Sleep problems

* Irritability

* Depression

In most cases, concussion symptoms will resolve within a few weeks or months. However, some people may experience persistent symptoms for months or even years. This is known as post-concussion syndrome (PCS).

PCS can cause a variety of problems, including:

* Cognitive problems, such as difficulty concentrating and memory loss

* Headaches

* Fatigue

* Sleep problems

* Mood changes

* Irritability

* Depression

* Anxiety

* Pain

* Vision problems

* Hearing problems

* Balance problems

* Coordination problems

PCS can have a significant impact on a person's life. It can make it difficult to work, go to school, or participate in social activities.

There is no cure for PCS, but there are treatments that can help to manage the symptoms. Treatments for PCS may include:

* Rest

* Medication

* Physical therapy

* Occupational therapy

* Speech therapy

* Cognitive rehabilitation therapy

If you think you may have a concussion, it is important to see a doctor right away. Early diagnosis and treatment can help to improve your chances of a full recovery.
