Here are the important stroke and TIA mimics:
- Systemic and metabolic insults: especially hypoglycemia, but also a very wide variety of other systemic insults such as infections (urinary tract infections, pneumonia) and toxins, all of which can cause re-expression of symptoms of old strokes.
- Peripheral neuropathies such as idiopathic seventh cranial nerve (Bell’s) palsy, peripheral vestibulopathy, and even acute limb ischemia.
- Postictal (Todd’s) paralysis.
- Multiple sclerosis.
- Migraine aura/psychogenic disorders/transient global amnesia.
