Concussions or mild traumatic brain injury occurs when brain suddenly shifts or shakes inside the skull and knocks against the bony surface. Concussion can cause a variety of physical, cognitive and emotional symptoms.
The most common early symptoms of concussions include dizziness, vertigo or loss of equilibrium, nausea, vomiting and headache.
Our brain is surrounded by a fluid known as cerebrospinal fluid. The fluid acts as shock absorber that dampens movement of the brain when a person is jolted. The human brain along with this protective fluid is enclosed inside a skull which acts as a protective shell. The outer covering of the skull is smooth but its inner portion is rough and boney. It is this rough, boney structure inside the skull that can injure the brain when a persons head is violently jarred.
Mild traumatic brain injury or cumulative concussions can have long term effects on human body ranging from minor headache or vertigo to serious and life threatening effects such as coma.
Common effects of concussions on human body are:
- Change in sleep pattern
- Poor memory
- Tinnitus (Ringing in ears)
- Loss of concentration
- Slowed reaction time
- Mood swings and change in personality
These effects may be noticeable right after the violent blow to the head or may be observed weeks after the initial jolt. A person’s symptoms may vary and include blurred vision, seeing stars, being dazed, possible nausea and sometimes partial or total memory loss. More serious effects of concussions may include severe headache, difficulty with mobility and co-ordination, difficulty talking and communicating, difficulty with sensation and various levels of consciousness.
