Anxiety symptoms can have a major impact on the course of a depressive illness, with delayed recovery, increased risk of relapse, greater disability and increased suicide attempts.There are increased rates of alcohol and drug abuse and particularly dependence,and around a third of individuals diagnosed with ADHD develop comorbid depression.Post-traumatic stress disorder and depression often co-occur.Depression may also coexist with attention deficit hyperactivity disorder (ADHD), complicating the diagnosis and treatment of both.Depression is also frequently comorbid with alcohol abuse and personality disorders.Depression can also be exacerbated during particular months (usually winter) for those with seasonal affective disorder.
