SUMMARY

A. History:
Dysfunction leads to disinhibition, poor judgment and insight.

B. Reflexes:
1. Grasp reflex: localizes to the contralateral abnormal hemisphere.
2. Palmomental reflex: causes protrusion of the lower lip.
3. Pout and snout reflex: elicited by scratching above the upper lip.

C. Other tests:
1. Foster-Kennedy syndrome – optic atrophy ipsilateral to the frontal lesion + papilloedema contralateral to the frontal lesion.
2. Interpret proverbs: patient with dysfunction will give concrete explanation.
3. Anosmia.
4. Gait apraxia – similar to shuffling.
