A woman experiences difficulty in reading after a left parietal lobe infarct. What additional feature is likely to be present?

The correct answer highlights the potential cognitive deficits that can arise from a left parietal lobe infarct, specifically relating to numerical processing. Acalculia refers to the loss of the ability to perform mathematical calculations, which can occur alongside other visual and spatial difficulties that may result from damage in this area of the brain.

In the context of a left parietal lobe infarct, individuals may struggle with integrating sensory input related to numbers, as this is a region that plays a crucial role in mathematical processing and comprehension. Consequently, the presence of dyslexia or difficulties with reading can often accompany acalculia, as both arise from disruptions to the brain's processing of language and numbers, respectively.

Other conditions listed, like confabulation, cortical deafness, and expressive dysphasia, do not directly relate to the specific deficits expected from a left parietal lobe infarct. Confabulation typically relates to memory issues, cortical deafness is a condition associated with auditory processing from temporal lobe damage, and expressive dysphasia primarily occurs with damage to Broca's area located in the frontal lobe, which is responsible for speech production. Thus, acalculia is the most logical additional feature to expect in a patient
