A 65-year-old Caucasian female was brought to the Emergency Department by her husband for increasing generalized weakness, slurred speech and new-onset facial droop. A non-contrast computerized tomography scan of her brain was negative; however, she was found to have a sodium level of 99 mmol/L. Her daily medications included hydrochlorothiazide, omeprazole and irbesartan. On physical examination, she was found to have slight confusion, lethargy, slowed speech, generalized weakness and left-sided facial droop but no other focal deficits. Over the course of her hospital stay, the patient's sodium levels were corrected slowly On the fifth day of admission, the majority of the patient's neurologic symptoms had resolved, suggesting her stroke-like symptoms were correctable with sodium repletion.

However, many other conditions can present dual sensory impairment. Accurate diagnosis is essential for providing patients with genetic counseling, prognostic information, and appropriate resources.

Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is an uncommon condition represented by an infantile-onset disorder, frequently arising from heterozygous mutations in the gene. Individuals with GLUT1-DS may present with early-onset seizures (typically manifesting before 4 years of age), developmental delay, and complex movement disorders. In fewer cases, stroke-like events or hemiplegic migraine-like symptoms are also reported, defined by unilateral paresis affecting 1 side of the body and/or one-half of the face, occasionally accompanied by speech impairment.
