Anterior choroidal artery (AChA) stroke triad: 

1. Contralateral hemiplegia 
2. Hemianesthesia 
3. Homonymous hemianopia 

Anterior choroidal artery is a branch of ICA and supplies multiple structures including posterior limb of internal capsule, VPL nucleus of thalamus, and lateral geniculate body 

– Left AChA stroke similar to L MCA stroke except speech is preserved in L AChA stroke 

 

TITF1 = benign hereditary chorea

Insomnia, worsening vision, difficulty walking, precocious puberty, inability to look up but pupils accommodate (Parinaud Syndrome) – think tumor of pineal gland (Pinealoma)
