Major depressive disorder

Expression

Sleep disorder: insomnia or excessive sleep.

Guilt and self-accusation: it will cause psychological burden to patients, and they always think they are worthless. Some minor mistakes will be easily magnified by people with severe depression, and they think they have no meaning to live.

Suicidal tendency: In order to get rid of all troubles, patients will have a strong desire to commit suicide, so it is easy for patients to commit suicide.

Most patients also have social problems, appear unsociable, suffer from low spirits, and often experience persistent fatigue and loss of appetite.

Associated Conditions

Major depressive disorder frequently co-occurs with other psychiatric problems. The 1990–92 National Comorbidity Survey (US) reports that half of those with major depression also experience lifetime anxiety, which is associated with other disorders such as generalized anxiety disorder. Anxiety symptoms can have a major impact on the course of a depressive illness, with effects including delayed recovery, increased risk of relapse, greater disability and increased suicide attempts. There are also increased rates of alcohol and drug dependency and abuse, and around a third of individuals who are diagnosed with ADHD develop co-morbid depression. Post-traumatic stress disorder, referred to as PTSD, 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 co-morbid with alcohol abuse and personality disorders. Depression can be exacerbated during particular months (usually winter) for those with seasonal affective disorder or SAD. While overuse of digital media has been associated with depressive symptoms, digital media may also be utilised in some situations to improve mood.
