Even though our brain is protected by the skull, it’s still highly vulnerable to damage. Acquired Brain Injury (ABI) refers to any brain damage that happens after birth, caused by either external trauma or internal factors, like strokes or infections. This excludes injuries from congenital disorders or birth complications. 

Types of ABI 

  • Non-Traumatic Brain Injury (Non-TBI): This happens due to internal issues like strokes, lack of oxygen, tumors, or infections. Stroke is one of the leading causes of disability worldwide, affecting millions of people each year. 
  • Traumatic Brain Injury (TBI): TBI occurs from external forces like falls, car accidents, or assaults. It affects millions globally and can result in long-term disabilities. 

Severity of ABI 

ABI can range from mild to severe, and the severity of the injury often dictates the type of symptoms and recovery time. 

  • Mild Injuries: Concussions are the most common form of mild TBI. They often occur from blows to the head and might cause symptoms like headaches, dizziness, confusion, and memory problems. Although concussions are typically not life-threatening, they should still be taken seriously, as repeated concussions or lack of proper recovery can lead to long-term cognitive and emotional issues, known as “post-concussion syndrome.” 
  • Moderate to Severe Injuries: These types of injuries can result in longer periods of unconsciousness, significant memory loss, and more profound cognitive or physical impairments. Severe injuries often require intensive rehabilitation and can lead to permanent changes in brain function, affecting mobility, communication, and overall independence. 

The Effects of ABI 

  • Cognitive Impact: Many people with ABI experience memory problems, trouble concentrating, and difficulty with decision-making. These issues can interfere with daily life and make tasks like learning, working, and socializing more challenging. 
  • Physical Symptoms: ABI can cause motor issues, such as muscle weakness or balance problems, sensory deficits, and chronic pain, including frequent headaches. 
  • Emotional and Behavioral Changes: People with ABI often experience mood swings, depression, anxiety, and difficulty controlling emotions or behavior. This can affect relationships and lead to social isolation. 

Rehabilitation and Support 

  • Recovery from ABI varies for each person and depends on factors like the severity and location of the injury. Rehabilitation, both cognitive and physical, is essential for managing the lasting effects and improving quality of life. 

In summary, while ABI is a complex and often life-altering condition, with proper care and support, individuals can work towards improving their daily functioning and well-being.
