What are likely neurological findings in a thrombotic stroke affecting the dominant MCA territory?

• A. Global aphasia
• B. Right-sided hemiplegia
• C. Ataxia
• D. Visual field defects

Answer: (A)

In a thrombotic stroke that affects the dominant middle cerebral artery (MCA) territory, global aphasia is a prominent neurological finding. This occurs when there is damage to the language centers in the dominant hemisphere of the brain, which is typically the left hemisphere in right-handed individuals and often in left-handed individuals as well. The MCA supplies blood to critical areas involved in language production and comprehension, including Broca's area and Wernicke's area. Damage to these areas leads to significant deficits in both the ability to speak and to understand language, resulting in global aphasia. In addition to this, patients may also experience loss of motor and sensory functions on the side of the body opposite to the affected hemisphere, but the primary focus of the question is on the language deficits associated with this type of stroke. While other findings such as hemiplegia, ataxia, and visual field defects can occur depending on the exact location and extent of the stroke, global aphasia specifically highlights the language deficits that arise from the dominant MCA territory involvement, making it the most relevant answer in this scenario.
