Q

Frontotemporal lobar degenerations

A

Heterogeneous group of non-AD dementias that preferentially affects frontal and temporal lobes. Pick’s disease falls in this category. Deterioration in social function and personality.

Q

Dementia with Lewy Bodies

A

Like Parkinson’s but Lewy bodies have less defined “halo” and are found in cortical regions. Consider with Parkinsonian motor symptoms with early Alzheimer’s-like deficits

Q

Focal seizures

A

Simple focal: still conscious, aura common, may experience motor, sensory, autonomic, or psychic signs

Complex focal: impaired consciousness (complete or mild), may experience automatisms, may or may not be preceded by aura

A

Stabilize Na+ inactivation gate prolonging absolute refractory period
Declining use because and pharmacokinetics

26
Q

Carbamazepine/Oxcarbamazepine

A

Stabilize Na+ inactivation gate prolonging absolute refractory period
Well tolerate with few side effects, may worsen absence seizures, risk of hyponatremia

Mechanism uncertain but helps inhibit high frequency firing of APs
Broad specter, first line for generalized seizures
Most teratogenic

30
Q
