Abstract
Background:
Aphemia, or pure motor mutism, is a phenomenon that has been reported previously in the literature and typically is associated with small infarcts in the inferior dominant precentral gyrus, pars opercularis, or inferior perirolandic gyrus. Clinically, it is important to distinguish aphemia from aphasia syndromes. Telemedicine is becoming more prevalent and involving neurologists across the country. This is an important consideration when addressing aphemic patients as many mistakes can be made during a virtual exam clouding a patient’s clinical picture.
Case Presentation:
Our patient is a 61-year-old female with a past medical history of hypertension, diabetes, and an old right frontoparietal stroke without any residual deficits. She presented after her family stated that she “quit speaking” for about seven hours. Initial neurological evaluation was done via telemedicine due to the COVID-19 pandemic and was pertinent for decreased consciousness, inability to answer either orientation question, a right facial droop, and aphasia. Later it was found that the patient exhibited a pure motor mutism rather than aphasia and had an MRI lesion in the left inferior precentral gyrus.
Conclusion:
Differentiating aphemia from aphasia is an important clinical skill for a neurologist to foster especially in the era of telemedicine. An intimate knowledge of the parts of a speech exam are vital in directing emergency staff during stroke evaluation. Additionally, distinguishing these clinical syndromes has implications with respect to prognosis and long-term rehabilitation.
