Genetics may contribute anxiety may run in families, however can be triggered by environment (like a thermostat, at threshold the heater kicks in) Possibly different patterns inherited, or tendency is inherited rather than specific disorder. Studies link ocd to problems in basal ganglia, frontal lobes.
