CO2-induced panic attacks: a twin study.

The American journal of psychiatry - 1 Sept 1998

Bellodi L, Perna G, Caldirola D, Arancio C, Bertani A, Di Bella D

Abstract excerpt

OBJECTIVE: The authors investigated the role of genetic factors in 35% CO2-induced panic attacks. METHOD: Ninety twins recruited from the general population were challenged with one-vital-capacity inhalations of 35% CO2-65% O2. Probandwise concordance rates were calculated and rates compared for...
