Differential Diagnosis for Dysphasia

The differential diagnosis for dysphasia can be organized into the following categories:

  • Single Most Likely Diagnosis + Stroke: This is the most common cause of acute onset dysphasia, particularly if it is accompanied by other focal neurological deficits. The sudden onset of symptoms is highly suggestive of a vascular event.
  • Other Likely Diagnoses + Traumatic Brain Injury: Head trauma can cause dysphasia, especially if the injury involves the left hemisphere of the brain, which is typically responsible for language processing. + Brain Tumors: Both primary and metastatic brain tumors can cause dysphasia by compressing or infiltrating areas of the brain responsible for language. + Infections (e.g., Encephalitis, Abscess): Certain infections can cause dysphasia, particularly if they involve the left hemisphere or areas critical for language processing. + Dementia: Certain types of dementia, such as primary progressive aphasia, can present with gradual onset of dysphasia.
  • Do Not Miss Diagnoses + Status Epilepticus: Non-convulsive status epilepticus can present with altered mental status and aphasia, making it crucial to consider and promptly treat to prevent long-term neurological damage. + Meningitis: Inflammation of the meninges can cause symptoms including dysphasia, and prompt treatment is essential to prevent serious complications. + Cerebral Vasculitis: Inflammation of the blood vessels in the brain can lead to stroke-like symptoms, including dysphasia, and requires immediate attention.
  • Rare Diagnoses + Multiple Sclerosis: Although more commonly associated with visual and motor symptoms, multiple sclerosis can rarely cause dysphasia, especially during an acute relapse. + Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-like episodes (MELAS): This rare genetic disorder can cause stroke-like episodes, including dysphasia, due to mitochondrial dysfunction. + Neurodegenerative Disorders (e.g., Frontotemporal Dementia, Corticobasal Degeneration): These conditions can present with dysphasia among other symptoms, but are less common than other causes listed above.
