Depression: A Sign of Underlying Disorders
When someone experiences depression, it could be an indication of various mood disorders. Many people are unaware that depression can be just one symptom of a more complex mental condition. Conditions like bipolar disorder, cyclothymic disorder, dysthymic disorder, and seasonal affective disorder not only result in depression but also produce other symptoms. Additionally, certain illnesses and chronic conditions can be responsible for triggering depression.
The intricate networks within the human body require a delicate balance. If this equilibrium is disrupted, the brain may send signals to the rest of the body that manifest as depression. Experienced psychiatrists carefully examine depression cases over time to determine whether it is occurring in isolation or as part of another underlying illness.
Substance Abuse and Depression
Excessive alcohol consumption and substance abuse can be major factors contributing to depression. Research has shown a connection between the overuse of alcohol and drugs and the biochemical changes associated with depression. When alcohol and drugs are used excessively, they can decrease the levels of serotonin and norepinephrine in the brain. Serotonin is often referred to as the “happy chemical” because it plays a crucial role in regulating sleep patterns, emotional responses, and the activity in immune pathways in the gut. It is important to note that in some cases, individuals who go through recovery and rehabilitation from substance abuse may experience the onset of depression. This type of depression is categorized as substance-induced mood disturbances, which occur as a result of a lack of the addictive substance.
