Depression

 Depressive disorders come in many different types, but each type has its own unique symptoms and treatments.

 Major depression, the most common type of a depressive disorder, is characterized by a combination of symptoms that interfere with the ability to work, study, sleep, eat, and enjoy once pleasurable activities. Such a disabling episode of depression may occur only once but more commonly occurs several times in a lifetime. Depression is also rated by your diagnosing physician or mental health professional in terms of its severity — mild, moderate, or severe. Severe depression is the most serious type.

 A less severe type of depression, dysthymia, involves long-term, chronic symptoms that do not disable, but keep one from functioning well or from feeling good. Many people with dysthymia also experience major depressive episodes at some time in their lives.

 Another type of depressive disorder is  bipolar disorder, also called manic-depressive illness. Not nearly as prevalent as other forms of depressive disorders, bipolar disorder is characterized by cycling mood changes: severe highs (mania) and lows (depression). Sometimes the mood switches are dramatic and rapid, but most often they are gradual. When in the depressed cycle, an individual can have any or all of the symptoms of a depressive disorder. When in the manic cycle, the individual may be overactive, overtalkative, and have a great deal of energy. Mania often affects thinking, judgment, and social behavior in ways that cause serious problems and embarrassment. For example, the individual in a manic phase may feel elated, full of grand schemes that might range from unwise business decisions to romantic sprees. Mania, left untreated, may worsen to a psychotic state.

 


 
Symptoms of Depression

 Not everyone who is depressed or manic experiences every symptom. Some people experience a few symptoms, some many. Severity of symptoms varies with individuals and also varies over time.

 DEPRESSION

  •  Persistent sad, anxious, or “empty” mood
  • Feelings of hopelessness, pessimism
  • Feelings of guilt, worthlessness, helplessness
  • Loss of interest or pleasure in hobbies and activities that were once enjoyed, including sex
  • Decreased energy, fatigue, being “slowed down”
  • Difficulty concentrating, remembering, or making decisions
  • Insomnia, early-morning awakening, or oversleeping
  • Appetite and/or weight loss or overeating and weight gain
  • Thoughts of death or suicide; suicide attempts
  • Restlessness, irritability
  • Persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders, and chronic pain

 Symptoms of Mania (for Bipolar Disorder)

MANIA

  •  Abnormal or excessive elation
  • Unusual irritability
  • Decreased need for sleep
  • Grandiose notions
  • Increased talking
  • Racing thoughts
  • Increased sexual desire
  • Markedly increased energy
  • Poor judgment
  • Inappropriate social behaviour

The key understanding about depression causes — and, in fact, causes for any mental disorder — is that we still do not know what causes these mental disorders. It is generally believed that all mental disorders are caused by a complex interaction and combination of biological, psychological and social factors. This theory is called the bio-psycho-social model of causation and is the most generally accepted theory of the cause of disorders such as depression by professionals.Types of depression run in families, suggesting that a biological vulnerability can be inherited. This seems to be the case with bipolar disorder. Studies of families in which members of each generation develop bipolar disorder found that those with the illness have a somewhat different genetic makeup than those who do not get ill. However, the reverse is not true: Not everybody with the genetic makeup that causes vulnerability to bipolar disorder will have the illness. Apparently additional factors, possibly stresses at home, work, or school, are involved in its onset.Some depressive disorder is often associated with changes in brain structures or brain function.

In some families, major depression also seems to occur generation after generation. However, it can also occur in people who have no family history of depression. People who have low self-esteem, who consistently view themselves and the world with pessimism or who are readily overwhelmed by stress, are prone to depression. Whether this represents a psychological predisposition or an early form of the illness is not clear.
