He felt normal for the first few minutes, but soon symptoms such as dizziness and loss of vision were observed.

Physical assaults or getting struck by something also leads to damage to the brain. Motor vehicle accidents are also a massive reason for causing head injuries in many patients. Most head injuries are observed in children below the age of fourteen. Older people aged more than sixty are also prone to head injuries as their reflex action is slow in case of falls.

Significant causes of head injuries include accidents, falling on the head, physical assaults, and a few others.

On average, a patient should be observed within two hours after getting injured on the head. If the patient is not responding very well, then a CT scan should be done within one hour to check for internal bleeding. Individuals must take care of their heads as it is one of the most crucial body parts.
