Secondary ADHD from head injury refers to attention difficulties and other ADHD-like symptoms that develop after a traumatic brain injury (TBI) in adulthood. Unlike childhood ADHD, which is a neurodevelopmental condition, secondary ADHD emerges as a direct result of brain damage, often from accidents, falls, or other head trauma. This condition can involve TBI-related symptoms such as impulsivity, distractibility, and restlessness.

One of the key features of secondary ADHD from head injury is the presence of executive dysfunction. This can include difficulties with planning, organising, problem-solving, and controlling emotions. Adults may also experience acquired attention issues, finding it harder to concentrate for long periods or manage multiple tasks. These changes can significantly affect daily functioning, relationships, and work performance.

How It Helps

Accurate Identification

Recognising secondary ADHD from head injury ensures that clinicians consider the role of past brain trauma when assessing attention and behaviour changes. This helps differentiate it from primary ADHD, which has different origins and developmental patterns.

Tailored Support

When TBI-related symptoms and acquired attention issues are identified, treatment can be tailored to address both cognitive rehabilitation and behavioural strategies. This may include occupational therapy, memory aids, and structured routines to help manage executive dysfunction effectively.

In summary, secondary ADHD from head injury is a distinct condition requiring careful assessment and targeted support, ensuring that interventions address both the effects of the injury and the ADHD-like symptoms it can produce.
