DSM definition of disease, disorder, and syndrome?

[Xalatan]

I find the term disorder slightly confusing as per dsm and would appreciate someone giving clear medically accurate definitions.

 

Disease: a medical condition with clear cut aetiology, pathology, treatment response and prognosis.

 

Syndrome: a set of clinical signs and symptoms. No implications of aetiology.

 

Disorder: a syndrome that causes present distress or disability, or increases the risk of suffering death, pain, loss of freedom.

 

Is this accurate?
