Re: What's the difference?
According to Dad the Shrink, the difference between a 'Disorder' and a 'Tendency' is one of degree. So, if you have the 'Disorder', then you have full blown symptoms which 'significantly' impair normal functioning. If you have 'tendencies', you do NOT have the disorder, but rather certain specific characteristics often associated with the Disorder. Not as serious, not as all encompassing, not as interferring with daily functioning.
Or, as he put it, the difference between a sniffle and TB.
