EpistemisAnomie
Specialty: Neurology.
Why it occurs
- Primary progressive aphasia (logopenic or semantic variant, focal neurodegenerative disorders)
- Alzheimer's disease in early or moderate stages
- Ischemic stroke in the language area of the dominant hemisphere (left parieto-temporal)
- Left temporal lobe brain tumor (such as glioblastoma or sphenoid cleft meningioma)
- Temporary focal epileptic seizures (postictual or ictal anomia)
Initial workup
Boston Naming Test (or other standardized neuropsychological language batteries); brain MRI focused on the left temporal and sylvian lobe; electroencephalogram if temporal lobe epilepsy with subtle seizures is suspected; lumbar puncture with Alzheimer's biomarkers (beta-amyloid, tau protein) if the course is insidious.
red flags
Sudden onset anomia associated with alexia, agraphia or absolute inability to understand simple commands, indicating acute vascular compromise of the left temporal lobe that requires stroke code activation for possible fibrinolysis or thrombectomy.
Standard management
- Donepezil — 5-10 mg/day) or Memantine (10-20 mg/day, NMDA receptor modulator useful in degenerative dementia with language impairment
- Intensive and adaptive language therapy (speech therapy / aphasiology).
