Final answer:
Major or Mild Neurocognitive Disorder Due to TBI is associated with a variety of symptoms including memory loss and impaired motor skills, often depending on which part of the brain is affected. Injuries can lead to permanent brain damage and secondary excitotoxic injuries for which there is currently no pharmacological treatment.
Step-by-step explanation:
Major or Mild Neurocognitive Disorder Due to Traumatic Brain Injury (TBI) is associated with a range of symptoms that can include memory loss, profound confusion, and personality changes. An individual who has suffered a TBI may experience disruptive memory loss, confusion about time or place, and have difficulty with planning and executing tasks. Depending on the severity and location of the injury, other symptoms such as impaired motor skills, balance and posture problems, speech changes, and psychological symptoms including dementia could also be present. Severe brain injuries often lead to permanent brain damage, with symptoms depending on the part of the brain affected.
TBI typically occurs when an external force injures the brain, which can result in neuronal structure damage and dysfunction. The injury can also lead to secondary issues such as excitotoxicity. Presently, there is no pharmacological intervention available to treat the secondary injury caused by TBI. Assessments like the mental status exam are utilized to evaluate and understand the cognitive abilities affected by the injury.
