A controversial study suggests that the violent behavior displayed by some teenagers who play several hours of video games a day is due to developmental damage to the frontal lobe region of the brain rather than the absorption of any specifically violent content.

is due to developmental damage to the frontal lobe region of the brain

I will prefer 1st option;

Reason:
1) DAMAGE vs DAMAGES (we cannot change from initial meaning - original sentence says DAMAGE as a global phenomenon rather than as 'multiple damages')

2) possessive : damages to REGION (possessive is adjective, ie extra information and therefore if we remove the adjective sentence should make sense; but it does not make sense; Possessive of inanimate things - generally avoid)
