There are three types of brain injury, Traumatic Brain Injury and Subtle Brain Injury.   Traumatic Brain Injury A traumatic brain injury (TBI) occurs when the brain is subject to serious trauma due to a head injury, which can often occur as a result of a road traffic accident, an assault, or a fall or an accident at work or home. After suffering from an injury, the patient may feel sick, dizzy and fall unconscious and there may be visible signs of damage to the head. The patient may also suffer headaches, fatigue, irritability and memory problems over the coming weeks and months. The long-term effects and symptoms of a traumatic brain injury depend on a number of factors, including the severity and location of the injury and the initial period of unconsciousness following the trauma. The main symptoms of a traumatic brain injury include: Dizziness Headaches Balance problems Cognitive difficulties Behaviour changes Loss of function The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates the body. Depending on how severe the injury is, rehabilitation may be necessary in order to teach the brain alternative ways to function to help to minimise the risk of long-term brain damage.   Acquired Brain Injury An acquired brain injury (ABI) is any instance of brain damage that transpires after birth. This can include traumatic injuries, however ABIs can also happen following: Strokes Tumours Aneurysms Meningitis or other diseases Diminished oxygen supply to the brain, such as suffocation, drowning, or heart attacks. Many of these events can result from cases of medical negligence or other situations in which the sufferer was owed a duty of care, and this duty has been breached by a third party. In these cases, you could still have a valid case, and our Brain Injury Lawyers can help you reach an outcome that works for you.   Subtle Brain Injury A subtle brain injury usually occurs when the brain is subject to trauma after an injury, which similarly may be due to a car accident, fall, or an accident at work. However, often the trauma may not appear to be too serious at first, especially if there are no visible signs of injury. Commonly, the person will appear completely uninjured and only close family and friends will notice a change in the person’s cognitive and behavioural behaviour. The most common long-term symptoms of subtle brain injuries include: Frequent headaches Dizziness Balance problems Behaviour changes Cognitive difficulties The long-term effects of a subtle brain injury depend on a number of factors, including the severity of the injury and where it’s located. However, there may be some damage to the brain after an accident which may cause long-term, disabling symptoms.
