Overview

Traumatic brain injury must be differentiated from other disease that causes headache, seizures and loss of consciousness such as subdural hemorrhage, meningitis, encephalitis, brain tumor, hemorrhagic stroke, neurosyphilis, migraine, hypertensive encephalopathy, wernicke’s encephalopathy, brain abscess, drug toxicity, conversion disorders, metabolic disturbance, multiple sclerosis, and seizure.

Differentiating Traumatic Brain Injury from other Diseases

Abnormal gait

Complex or atypical migraine + - + + - - + - - Family history of migraine - - Clinical assesment Presence of aura, nausea, vomiting

CNS abscess + + - - + + + - - History of drug abuse, endocarditis, immunosupression + leukocytes, glucose and protien MRI is more sensitive and specific High grade fever, fatigue,nausea, vomiting
Drug toxicity - + - + + + - + - - - - Drug screen test Lithium, Sedatives, phenytoin, carbamazepine
Conversion disorder + + + + + + + + History of emotional stress - - Diagnosis of exclusion Tremors, blindness, difficulty swallowing
Metabolic disturbances (electrolyte imbalance, hypoglycemia) - + + + + + - - + - - Hypoglycemia, hypo and hypernatremia, hypo and hyperkalemia Depends on the cause Confusion, seizure, palpitations, sweating, dizziness, hypoglycemia
