Which tests are recommended for aphasia?
There are three common tests for aphasia. These are the MTDDA, PICA, and the Boston.
The MTDDA or the Minnesota test for Differential Diagnosis of Aphasia is the most comprehensive. It is divided into 5 sections of auditory Disturbances, visual and reading disturbances, speech and language disturbances, visuomotor and writing disturbances, and disturbances of numbers and arithmetic processes.
The PICA or Porch Index of Communicative Ability is for the goal of evaluation and measures changes based on a multidemensional scoring system. It has 18 subtests and 4 language modalities of object manipulation, visual matching, and copying abstract forms.
The Boston is the Boston Diagnostic Aphasia Examination is used for the diagnosis of the type of aphasia and leads to theories on the location of the brain damage causing the aphasia. It consists of 27 subtests.
Aphasia, pathological alterations of language, is a handicap, consecutive to brain lesions located in the left hemisphere of right handed persons and can occur in subjects with normal intelligence and which do not present disturbances of affectivity and no deficiencies of perceptual and motor functions.Aphasia is a loss of speech, disturbance of the capacity to use the rules which produce and understand verbal messages.
All patients must be doing a complete blood count, biochemistry, a CT of the brain.
MRI can show a cerebral infarction, may find a tumor, a degenerative disease and multiple sclerosis. If they are are negative it should be consulted a neurologist before requesting a lumbar puncture.
If aphasia, is intermittent, Electroencephalogram should be done to rule out epilepsy and carotid artery Doppler ultrasound has to be made to rule out carotid stenosis or ulcerated atherosclerotic plates at this level.
Angiography may be suggestive, but a neurologist should be consulted before this.
