Case Study 3
A 50-year-old African American male presents with complaints of dizziness left arm weakness and fatigue. PMH: poorly controlled diabetes, hypertension, hyperlipidemia
PE: Upon exam, you noted a very mild dysarthria, he understands and follows commands very well. Mild weakness on the left side of the face is noted, and left sided homonymous hemianopsia but no ptosis or nystagmus or uvula deviation.

To Prepare:

You will either select or be assigned one of the three case studies provided.
Reflect on the provided patient information including history and physical exams.
Think about a differential diagnosis. Consider the role the patient history and physical exam played in your diagnosis.
Reflect on potential treatment options based on your diagnosis.

Based on the provided case study, the patient is a 50-year-old African American male with a history of poorly controlled diabetes, hypertension, and hyperlipidemia. He presents with complaints of dizziness, left arm weakness, and fatigue. The physical exam reveals mild dysarthria, mild weakness on the left side of the face, left-sided homonymous hemianopsia, but no ptosis, nystagmus, or uvula deviation.
Differential Diagnosis:
Ischemic stroke: The patient’s age, race, and medical history (diabetes, hypertension, and hyperlipidemia) put him at a higher risk for an ischemic stroke. The presence of left-sided weakness, dysarthria, and homonymous hemianopsia also support this diagnosis.
Transient ischemic attack (TIA): Given the patient’s risk factors and symptoms, a TIA could also be considered. However, TIAs typically resolve within 24 hours, so the duration of the patient’s symptoms would be important to determine.
Hemorrhagic stroke: Although less likely than an ischemic stroke, the patient’s hypertension and symptoms could also suggest a hemorrhagic stroke.
Diabetic neuropathy: The patient’s poorly controlled diabetes could contribute to neuropathy, which may cause weakness and sensory disturbances. However, this diagnosis is less likely given the patient’s other neurological symptoms.
Role of Patient History and Physical Exam:
The patient’s history and physical exam play a crucial role in narrowing down the differential diagnosis. The patient’s age, race, and medical history of poorly controlled diabetes, hypertension, and hyperlipidemia increase the likelihood of a cerebrovascular event. The physical exam findings, such as left-sided weakness, dysarthria, and homonymous hemianopsia, further support a neurological disorder, specifically a stroke or TIA.
Potential Treatment Options:
If an ischemic stroke or TIA is diagnosed, the following treatment options may be considered:
Immediate medical intervention: If the patient is within the appropriate time window (typically 3-4.5 hours from symptom onset), intravenous tissue plasminogen activator (tPA) may be administered to dissolve the clot and improve blood flow to the affected area.
Antiplatelet therapy: Aspirin or other antiplatelet medications may be prescribed to prevent further clot formation.
Anticoagulant therapy: If the patient has atrial fibrillation or other conditions that increase the risk of clot formation, anticoagulant medications may be prescribed.
Blood pressure management: Controlling the patient’s hypertension is crucial to prevent future strokes. This may involve lifestyle modifications and/or medications.
Diabetes management: Ensuring the patient’s diabetes is well-controlled can help reduce the risk of future strokes. This may involve lifestyle modifications, medications, and regular monitoring of blood glucose levels.
Lipid management: Controlling the patient’s hyperlipidemia can also help reduce the risk of future strokes. This may involve lifestyle modifications and/or medications such as statins.
In conclusion, the patient’s history and physical exam findings suggest a neurological disorder, with an ischemic stroke or TIA being the most likely diagnosis. Further diagnostic testing, such as imaging studies, would be necessary to confirm the diagnosis and guide appropriate treatment.
