Purpose
The primary objective of this Phase 1 crossover study is to evaluate the neuropsychological effects of Lacosamide (LCM) compared to Carbamazepine Immediate Release (CBZ-IR) after administration in healthy subjects. Safety, tolerability, and pharmacokinetic data will also be collected.

- Mean Within-subject Difference In The Overall Neuropsychological Composite Score During Both Treatment Periods [ Time Frame: From 6-week Treatment Period 1 to 6-week Treatment Period 2 (Visit 1- Visit 9) ] [ Designated as safety issue: No ]The overall composite score will be computed as the sum of the individual cognitive test scores from computerized tests and non-computerized neuropsychological tests (including behavioral questionnaires) after transformation to a Z-scores to form an overall composite Z-score. The Z-score will be calculated using the values (mean and standard deviation) from the average of the scores from 3 non-drug conditions (Baseline, first Washout Period, and second Washout Period).

Detailed Description:
Approximately 50 subjects at multiple sites will crossover to receive both treatments (lacosamide [LCM]and carbamazepine immediate release [CBZ-IR]) in a randomized order during the 2 study treatment periods (Treatment Period 1 and Treatment Period 2).
A Screening Visit will be conducted to evaluate subject eligibility for enrollment into the study. Eligible subjects will return up to 21 days after the Screening Visit and begin Treatment Period 1. During Visit 2, eligible subjects will be randomized to receive either LCM 300 mg/day or CBZ-IR 600 mg/day. Subjects will be treated with their first randomized Antiepileptic Drug (AED) for 6 weeks (Titration Period [21 days] and Maintenance Period [21 days]). Subjects then complete a 28-day Taper/Washout Period, during which their first AED will be tapered over 4 days followed by a 24-day Washout Period, where subjects will receive no AED. Upon completion of the Taper/Washout Period, subjects will begin Treatment Period 2.The procedures and assessments for Treatment Period 1 will be repeated for Treatment Period 2 (with the same duration of treatment).
