Broca's Aphasia Evaluation
The evaluation of aphasia begins with a medical history and physical examination.
The diagnosis of aphasia can be made without testing, but testing is required to determine the underlying cause for aphasia.
Tests for aphasia may include:
- CT scanning of the brain
- MRI scan of the brain
- SPECT scanning:
- A newer method that may provide earlier detection of stroke in some cases
- PET scanning of the brain:
- Can detect changes in brain metabolism and activity.
- Blood clotting studies
- Blood electrolytes
- Blood glucose
- Pulse oximetry
Other tests that may be required if a stroke or TIA is the cause for the aphasia:
- Carotid angiogram:
- A special x-ray procedure that can detect blood vessel narrowing in the carotid arteries, which often cause strokes.
- Carotid duplex ultrasound, or doppler ultrasound:
- Can detect narrowing and reduced blood flow in the carotid arteries that supply the brain
- C-reactive protein
- Coagulation profile and bleeding time
- Homocysteine level
- LDL level
- HDL level
- VLDL level
- Total cholesterol level
- Often elevated in people who are at high risk for stroke
