If a suspected brain injury has occurred, the patient undergoes a series of medical imaging, which could include MRI(magnetic resonance imaging) or CT (computed tomography) scan. After the diagnosis of a brain injury, a speech and language pathologist will perform a variety of tests to determine the classification of aphasia. Additionally, the Boston Assessment of Severe Aphasia (BASA) is a commonly used assessment for diagnosing aphasia. BASA is used to determine treatment plans after strokes lead to symptoms of aphasia and tests both gestural and verbal responses. Cognitive functions can be assessed using the Cognitive Test Battery for<unk>  (CoBaGa). The CoBaGa is an appropriate measure to assess a person with severe aphasia because it does not require verbal responses, rather manipulative answers. The CoBaGa assesses cognitive functions such as attention, executive functions, logical reasoning, memory, visual-auditory recognition, and visual-spatial ability. Van Mourik et al. conducted a study in which they assessed the cognitive abilities of people with<unk>  using the<unk>  Neuropsychological Battery. This test assesses attention/concentration, memory, intelligence, and visual and auditory nonverbal recognition. The results of this study helped the researchers determine there were varying levels of severity among individuals with<unk> .
