The Psychological Aftermaths of Traumatic Brain Injury
Bhumi Sharma, Khushi Jain Traumatic Brain Injury (TBI) can lead to overwhelming and lasting effects on a person’s cognitive, behavioural, emotional and overall psychological functioning. Issues like memory loss, mood swings, aggressive behaviour and in some cases psychological disorders like major depressive disorder, anxiety disorder; are not that uncommon in people who have suffered from a TBI. Research in this field can provide us with a better understanding of the psychological effects of a physical injury and can help us build better interventions and treatments. It can also help in exploring the relationship between TBI and development of psychological disorders and delve deeper into neuropsychology. This article will talk about long-term cognitive, emotional, and behavioral outcomes of TBI; and the relationship between TBI and the development of psychiatric disorders. The Multifaceted Impact of Traumatic Brain Injury on Mental Health Traumatic brain injury (TBI) is the leading cause of disability in those aged under 40 years, commonly affecting young males injured in road traffic accidents. The injury interrupts the important developmental transition to independence and results in significant emotional distress (Ponsford et al. 1995). Clarification is also required concerning the contribution of pre-injury psychiatric history to post-injury disorders. The literature variously posits that preinjury disorders increase risk for post-injury disorder development (Deb et al. 1999; Ashman et al. 2004), that they are not significantly associated (Fann et al. 1995; Jorge et al. 2004), or that those without a pre-injury history have an increased risk of post-injury psychiatric disorder (Fann et al. 2004). Importantly, there are dramatic variations in reported incidence and prevalence rates between studies, with post-injury incidence of depression ranging from 15.3% to 33% and prevalence from 18.5% to 77% (Kim et al. 2007). Reported prevalence of anxiety disorder ranges between 19% (Rutherford et al. 1977) and 70% (Lewis, 1942). Traumatic brain injury (TBI) is a critical condition that impacts individual cognitive functions (memory deficits, post-traumatic amnesia, and attention challenges), emotional stability (depression, anxiety, and PTSD), and behavioral functions (aggression, impulsivity, and social withdrawal).Historically, TBI has been linked to post-traumatic amnesia (PTA), a global cognitive disturbance characterized by confusion, disorientation, and difficulty in storing or retrieving new information. This stage often includes retrograde amnesia, significantly impacting patients’ ability to reintegrate into daily life (Halalmeh et al., 2023). Early studies on sports-related concussions identified that individuals with repeated concussions exhibit greater susceptibility to neuropsychological deficits and long-term cognitive impairments. Younger children, in particular, are at a higher risk of prolonged cognitive deficits, emphasizing age as a critical factor influencing recovery trajectories. Recent advancements highlight virtual reality (VR)-based rehabilitation as a promising intervention. Semi-immersive VR has shown superior results in improving attention, memory, and executive functions compared to traditional methods, offering an engaging approach to cognitive recovery post-TBI (De Luca et al., 2019). However, significant gaps persist. Given the individual variability in TBI experiences, these findings may not be generalizable across diverse populations. Personalized rehabilitation plans tailored to individual needs remain underexplored. However, future research must address the heterogeneity of TBI experiences to ensure equitable and effective interventions for all patients. TBI and Psychological Disorders Traumatic Brain Injury or TBI is when the brain suffers an injury from an external force and can range from mild to severe, which can even lead to death. The relationship between TBI and psychological disorders is intimate but complex. The interplay between neurological damage from TBI and the onset of psychiatric conditions is complex, and understanding this relationship is crucial for improving the treatment and outcomes for individuals affected by brain injuries. The most common consequences of TBI are psychological and psychosocial impairment and may result in a broad range of emotional and behavioural abnormalities. The most severe manifestation is in the form of psychological disorders. According to studies the frequency of psychiatric disorders in individuals is higher than in the general population and in individuals prior to injury. These suggest that the chance of mood and anxiety disorders to occur increases during the first year post injury. Around 70% of people after suffering from a Traumatic Brain Injury exhibited Sleep-wake dysfunction. Post-mortem detailed evaluations of the brains of patients who did and did not suffer from TBI showed a significant reduction in hypocretin neurons which causes excessive daytime sleepiness. Behavioral, Cognitive and Emotional Effects on TBI Traumatic brain injuries extend far beyond physical damage, significantly impacting an individual’s daily functioning and overall quality of life. These effects are not limited to the individual but also influence their social environment and the people around them.This theme is vital as it sheds light on how various impairments such as memory loss, emotional instability, and social withdrawal, aggression, impulsivity undermines an individual’s independence and productivity. The complexity and uniqueness of each injury highlights the necessity for tailored interventions, as a standardized approach fails to accommodate the diverse challenges faced by TBI survivors. Understanding the multifaceted impacts of TBI is crucial for developing effective strategies to support individuals in regaining functionality and improving their quality of life, while also easing the burden on their caregivers and support systems. The interventions are necessary as the course of recovery for a TBI survivor can be lengthy and challenging both on the survivor and the caregiver as it requires proper care, timed medications, follow ups which can become a burdened in the caregiver’s life and it may result in emotional disturbances in caregivers such as anxiety or depression and its adverse effects may stay longer in their life. Hence tailored approaches, such as cognitive rehabilitation, psychotherapy, and structured support systems, help survivors regain independence while providing caregivers with the resources and coping strategies needed to manage their roles effectively. This holistic approach ensures better outcomes for both survivors and their support networks. TBI in Military Personnel: Unique Cognitive and Emotional Challenges Most studies presented previously describe TBI in civilian populations. However, given the high rates of TBI among veterans and military service members, it is crucial to understand how it affects their cognitive, emotional, and behavioral functions. The acute effects of
