• Syncope
• Migraine aura
• Seizure
• Hypertension

The correct answer is: Hypertension   Explanation: A transient ischemic attack (TIA) is a temporary episode of neurologic dysfunction caused by focal brain ischemia without acute infarction. Several conditions can mimic TIA symptoms, but hypertension is not a typical mimic. Common TIA Mimics:

1. Syncope – Brief loss of consciousness due to cerebral hypoperfusion (can resemble TIA if accompanied by transient weakness).
2. Migraine aura – Reversible neurologic symptoms (e.g., visual changes, paresthesias) that may mimic TIA.
3. Seizure – Postictal Todd’s paralysis can appear like a TIA.
4. Hypoglycemia – Can cause focal neurologic deficits.
5. Peripheral vestibular disorders (e.g., BPPV) – May mimic vertebrobasilar TIA.

Why Hypertension is NOT a Mimic:

• While hypertension is a risk factor for stroke/TIA, it does not directly cause transient focal neurologic deficits.
• Severe hypertension may lead to hypertensive encephalopathy (global confusion, headache), but this is a diffuse process, not focal like TIA.

Thus, hypertension is the correct answer as it does not typically mimic TIA.
