A 70-year-old man with diabetes presented with slurred speech and altered behavior lasting 30 minutes. He was diagnosed with a transient ischemic attack caused by low blood sugar. Tests showed high HbA1c and cholesterol. An MRI showed age-related brain atrophy and ischemic lesions. He was admitted, prescribed medications including aspirin and antidiabetic drugs, and counseled on diet and blood sugar control to prevent future attacks.
