Behavioral and Psychiatric Symptoms in Patients with Severe Traumatic Brain Injury: A Comprehensive Overview

Area of Science:

• Neuroscience
• Psychiatry
• Rehabilitation Medicine

Background:

• Traumatic brain injury (TBI) results from external forces altering brain structure or function.
• Moderate to severe TBI survivors often face persistent neuropsychological and neuropsychiatric disorders (NPS).
• NPS prevalence post-TBI ranges from 25-88%, significantly increasing the risk compared to the general population.

Purpose of the Study:

• To investigate the most frequent psychiatric, behavioral, and emotional symptoms in TBI patients.
• To enhance clinical practice for TBI-related neuropsychiatric disorders.
• To guide the development of tailored rehabilitation training programs.

Main Methods:

• Literature review of studies on TBI.
• Analysis of prevalence rates and risk factors for NPS after TBI.
• Examination of symptom onset and stability timelines.

Main Results:

• Cognitive, behavioral, and emotional deficits typically emerge within six months post-TBI, stabilizing after 1-2 years.
• NPS significantly affect social, occupational, and familial relationships, reducing quality of life.
• Patients with TBI exhibit a substantially higher risk of developing NPS.

Conclusions:

• Understanding frequent NPS symptoms is key to improving TBI patient care.
• Early identification of risk factors can mitigate long-term sequelae.
• Personalized rehabilitation strategies are essential for managing TBI-induced neuropsychiatric conditions.
