Any injury to the head is called a Head Injury. The purpose of the head is to protect the delicate brain behind the strong bones. An injury to the head can lead to an internal injury to the brain. It is the Brain injury which carries a great risk and needs immediate attention.
Head or Brain Injury
Traumatic brain injury (TBI) can significantly affect many cognitive, physical, and psychological skills. Physical deficit can include ambulation, balance, coordination, fine motor skills, strength, and endurance. Cognitive deficits of language and communication, information processing, memory, and perceptual skills are common. Psychological status is also often altered. Adjustment to disability issues are frequently encountered by people with TBI.
Brain injury can occur in many ways. Traumatic brain injuries typically result from accidents in which the head strikes an object. This is the most common type of traumatic brain injury and brain tumor. However, other brain injuries, such as those caused by insufficient oxygen, poisoning, or infection, can cause similar deficits.
Mild Traumatic Brain Injury (MTBI) is characterized by one or more of the following symptoms:
A brief loss (or no loss) of consciousness, loss of memory immediately before or after the injury, any alteration in mental state at the time of the accident, or focal neurological deficits. In many MTBI cases, the person seems fine on the surface, yet continues to endure chronic functional problems. Some people suffer long-term effects of MTBI, known as post-concussion syndrome (PCS). Persons suffering from PCS can experience significant changes in cognition and personality.
Most traumatic brain injuries result in widespread damage to the brain because the brain ricochets inside the skull during the impact of an accident. Diffuse axonal injury occurs when the nerve cells are torn from one another. Localized damage also occurs when the brain bounces against the skull. The brain stem, frontal lobe, and temporal lobes are particularly vulnerable to this because of their location near bony protrusions.
The brain stem is located at the base of the brain. Aside from regulating basic arousal and regulatory functions, the brain stem is involved in attention and short-term memory. Trauma to this area can lead to disorientation, frustration, and anger. The limbic system, higher up in the brain than the brain stem, helps regulate emotions. Connected to the limbic system are the temporal lobes which are involved in many cognitive skills such as memory and language. Damage to the temporal lobes, or seizures in this area, have been associated with a number of behavioural disorders. The frontal lobe is almost always injured due to its large size and its location near the front of the cranium. The frontal lobe is involved in many cognitive functions and is considered our emotional and personal control center. Damage to this area can result in decreased judgement and increased impulsivity.
What are the symptoms of Head Injury (Brain Injury)?
The symptoms of head injury can vary from almost none to loss of consciousness and coma. As well, the symptoms may not necessarily occur immediately at the time of injury.
- Vomiting, Speech difficulty, difficulty in swallowing
- Bleeding from ear
- Numbness of body
- Altered Mental Status
Coma may be present if the patient doesn’t wake completely and is defined as a prolonged episode of loss of consciousness.
The treatment depends upon the nature of injury caused like- Spine surgery in India, brain surgery and brain tumor.
Clot Removal: If there is a collection of blood in the layers of the brain coverings, it has to be removed surgically by creating a burr hole.
Conservative Management: It has to be followed when there is loss of consciousness or altered mental status. A wait and watch policy is followed, generally in the hospital under the guidance of a specialist.
Whatever be the injury to the head, the attention to the sufferer has to be immediate. The patient needs to seek a professional help at the earliest and that is the key to a successful treatment.
