Seizures
Normal gate
Blind with normal PLR
Behavior changes

Question 15

Deficits associated with intracranial cerebrum/forebrain lesion

Answer 15

Seizure 
Normal gate 
Blind w/ normal PLR 
Behavior changes 
Circling (towards the lesion) 
Head pressing 
Menace deficit on contralareral side 
Hemi neglect

Question 16

Deficits associated with intracranial diencephalon/forebrain lesion

Answer 16

Similar to cerebrum lesions
AND
Endocrine dysfunction - depending on hypothalamus/purity the involvement (PU/PD thalamic pain sydrome ect)

Decreased/absent menace (depending on involvement of optic N/lateral geniculate nucleus (LGN))

Stupor/coma - depending on ascending reticular activating system ARAS (mostly in brainstem but some communication to diencephalon)
