Summary

This trial is testing buspirone, a medication usually used for anxiety, to see if it can help reduce irritability and aggression in people who have had a traumatic brain injury. The study involves 74 participants who will receive buspirone. The goal is to see if buspirone can make a positive difference in their behavior by calming the brain. Buspirone is a new anxiolytic agent that has been shown to reduce aggression and anxiety without causing sedation or cognitive side effects.

Who is the study for?
This trial is for adults aged 18-70 with traumatic brain injury (TBI) who have experienced increased irritability or aggression since their injury, which occurred at least 6 months prior. Participants must not plan any medication changes during the study and need a reliable observer to report on their behavior.
What is being tested?
The trial tests whether Buspirone, a medication typically used for anxiety, can help control post-TBI irritability and aggression compared to a placebo. Patients will be randomly assigned to receive either Buspirone or an inactive pill.
What are the potential side effects?
Buspirone may cause side effects such as dizziness, nausea, headache, nervousness, lightheadedness, excitement, and trouble sleeping. The severity of these side effects varies from person to person.

Other Research
Behavioral therapy for Traumatic Brain Injury (TBI) focuses on modifying behavior through structured interventions and coping strategies. This approach helps patients manage irritability and aggression, which are common post-TBI symptoms. By teaching patients to recognize their vulnerabilities and develop planned responses, behavioral therapy aims to improve emotional regulation and social interactions. This is crucial for TBI patients as it enhances their ability to function in daily life, reduces the risk of negative behaviors, and promotes long-term recovery.
