A concussion is a brain injury that disrupts regular brain activity. Alteration in mental state or degree of awareness, as well as other instant and temporary changes in brain function, are all part of the clinical syndrome known as “concussion” in the medical field.

• Headache.
• Feeling sick to one’s stomach or vomiting
• Issues maintaining balance; vertigo; lightheadedness.
• Blurry or double vision.
• Confusion.
• Brief lapse in awareness.
• Feeling sleepy or exhausted.

Your mind is as soft as gelatin. Cerebrospinal fluid in the cranium protects your brain from bumps and jolts.

Brain damage can also be caused by the rapid acceleration and deceleration of the cranium, as in a vehicle accident or when someone shakes you forcefully.

Bleeding in or around the brain is a potential complication of this type of brain injury, which can lead to signs like persistent sleepiness and mental disorientation. These signs may appear right away or at a later time.

Concussions have long-term consequences such as:

• Post-concussion syndrome
• Multiple concussions
• Difficulty remembering names or word-finding
• Dementia
