Depression: What are signs and symptoms

Although depression is a psychological disorder, it may be brought on by physiological problems within a person as well. It has often been noticed that depression is followed by bouts of physical illness and continues even after the person has recovered. This is due to the fact that the illnesses may end up causing the chemical imbalance within the brain, thus causing the neurotransmitters to function abnormally.

This is a typical symptom when either a major physiological or psychological reason has resulted in depression. Many doctors and patients have noticed that things in which they had a high interest earlier would either dwindle or not be there at all within a short period of time. This with a few other symptoms clearly points to depression.

Depression can be triggered by certain medications such as Accutane among others. Accutane specifically modifies the production of certain hormones to treat acne. However, the hormonal triggers may involuntarily trigger depression by causing chemical imbalances within the brain.

This might come as a surprise, even happy life changing events can lead to depression. This has been primarily attributed to the shock experienced when major changes occur in a person's life. The end of familiarity with a life or job which they were accustomed to might be too unsettling and thus, may cause a chemical imbalance which may lead them to depression.
