Neuropsykologinen kuntoutus Internetissä (IRENE)

Intervention group goes through a web-based neuropsychological intervention program. The program includes eight structured sessions regarding general neuropsychological symptoms after ABI - problems with fatigue, attention, executive functions and memory. A new session opens after the previous one is completed, and after a minimum of 3 days between the sessions. The intervention takes approximately 2 months depending on the progression pace of a patient. The eight sessions consist of psychoeducation, self-assessments, cognitive strategy training and feedback (automatic or given by a monitoring neuropsychologist). A neuropsychologist from HUS monitors patients' progression and provides personal feedback when needed. Participants can also be in contact with a monitoring neuropsychologist via message feature of the program.

Sessions of the digital neuropsychological program:

1. Subjective functional ability and goals
2. Fatigue after ABI
3. Attention and concentration
4. Memory
5. Memory strategies
6. Working memory and executive functions
7. Emotional reactions
8. Summary and future goals
