Agoraphobia is often accompanied by panic attacks.
Tips
memory
Reads literally as 'plaza-fear-illness,' a calque of Greek agora ('marketplace, plaza') + phobia. The 症 suffix marks medical conditions - pair with 抑郁症 ('depression'), 失眠症 ('insomnia').
mistakes
Don't confuse with 幽闭恐惧症 ('claustrophobia') - that's the opposite phobia (closed spaces). Note also that mainland clinical writing usually says 广场恐惧症 (with 惧 instead of 怖); 广场恐怖症 is the recorded variant.
