DEPRESSION
The following video shows a day in the life of an individual living with depression. The take home point is for you to see what an individual who is clinically depressed goes through on a daily basis .It will also help you to formulate ideas about how to approach a depressed patient in efforts to manage their care in a manner that will improve their quality of life.
DEPRESSION
Depression is a condition that many individuals encounter at some point in their lives.
Depression can last from a couple of days to years and has various effects on the individual.
A risk factor for depression is major life changes, which causes the individual to feel worthless and decreases interest in normal activities. Life events or changes include: death of a loved one, severe medical condition , or other bad news.
In addition, hormone and neurotransmitter imbalances may predispose an individual to depression (Barkley, 2021).
Individuals with depression may or may not recognize the symptoms and many do not seek medical for treatment.
DEPRESSIVE DISORDERS
Major Depressive Disorder-consists of a syndrome of mood, physical, and cognitive symptoms that occur at any time in life.
Complaints include loss of interest of pleasure, withdrawal from activities, feelings of guilt, inability to concentrate, cognitive dysfunction, anxiety, fatigue, feelings of worthlessness, somatic complaints, loss of sexual drive, and thoughts of death.
Unemployment has been associated with depression.
DEPRESSION
DEPRESSIVE DISORDERS
Psychotic major depression- occurs more frequently in adults over the age of 50.
Patients experience delusions, paranoia, impending annihilation (complete destruction ) , and somatic concerns.
**Major Depression with atypical features **is characterized by hypersomnia, overeating, lethargy, and mood reactivity.
**Melancholic Major Depression is characterized **by a lack of mood reactivity seen in atypical depression, the presence of anhedonia (no pleaseure in activity) , and severe vegetative symptoms.
Major Depression with a seasonal onset (SAD: Seasonal affective disorder) is noted with circadian rhythms during fall and winter months thought to be due to decease exposure to full-spectrum light. Symptoms include carbohydrate craving, lethargy, hyperphagia (excessive eatting ) , and hypersomnia.
Major Depression with peripartum onset occurs during pregnancy or begins up to 4 weeks after delivery.
**Persistent Depressive Disorder (dysthymia) **is a chronic depressive disturbance. Sadness, loss of interest, and withdrawal from activities over a a 2 or more year period are necessary for diagnosis.
**Premenstrual Dysphoric Disorder **is depressive symptoms during the late luteal phase of the menstrual cycle.
DEPRESSION
DIAGNOSIS
The findings associated with depression include: feeling guilty, worthless and helpless, suicidal ideations, problems with sleep, pain with no apparent cause, and poor appearance (Barkley, 2021).
In order to diagnose an individual with depression, five of the following must be present for 2 weeks:
- Depressed mood
- Marked diminished interest or pleasure
- Significant weight loss or gain
- Cannot sleep or sleeping too much
- Psychomotor agitation or retardation
- Fatigue or loss of energy
- Feelings of worthlessness or excessive guilt
- Diminished ability to concentrate
- Suicidal ideation
DEPRESSON
LABS
The following labs or diagnostic test maybe ordered to make sure the individual does not have an underlying disease process:
Test for vitamin deficiency: B12, Folate
Health conditions: Thyroid function, glucoses, CBC, Renal function, EKG (Barkley, 2021).
Major Depression Inventory
The Major Depression Inventory (MDI) is a self-rating scale used for the diagnosis or measurement of depression, according to both DSM-IV major depression and ICD-10 moderate to severe depression criteria.
The symptoms should have been present nearly every day during the past 2 weeks. In both the DSM-IV and ICD-10, the items of depressed mood and lack of interest are considered as the core symptoms of depression.
For the diagnosis of major depression, either item 1 or 2 should be among the 5 of 9 items present. Items 4 and 5 are combined, with only the highest answer category is considered and a total number of items of nine. As a diagnostic tool, the 10 items are dichotomized for the presence (1) or absence (0) of each symptom. As a measuring tool, the items are given a value (0-5) and summed up to a theoretical score of 0 to 50.
The cutoff score is 26 for the diagnosis of major (moderate to severe) depression.
The sensitivity of the MDI algorithms is between 86% and 92%, while the specificity is between 82% and 86% (see the image below). [13]
The Patient Health Questionnaire is a self-administered tool of 2 (PHQ2) or 9 (PHQ9) items. A meta-analysis found sensitivity to be 80% and specificity of 92%. The PHQ2 is a screening tool for depression that assesses the frequency of depressed mood and anhedonia over the past 2 weeks, scoring each as 0 (“not at all”) to 3 (“nearly every day”).
A PHQ-2 score of greater than 3 had a sensitivity of 83% and a specificity of 92% for major depression. [5, 12]
The PHQ 9 establishes the clinical diagnosis of depression and can additionally be used over time to track the severity of symptoms over time.
The cut point of the PHQ9 is equal or greater than 10, which has a sensitivity of 88% and a specificity of 88% for major depression.
PHQ-9 scores of 5, 10, 15, and 20 are representative of mild, moderate, moderately severe, and severe depression, respectively (see the image below). [4, 6]
Geriatric Depression Scale
The Geriatric Depression Scale (GDS) was specifically developed for use in geriatric populations, originally as a 30-item scale. It was modified a 15-item scale, which has been widely used. The GDS was later reduced to 5 items, so as to be better received by elderly patients. The questions elicit only “yes” or “no” responses, making comprehension easier compared with multiple-choice answers.
The 5-item scale has a sensitivity of 94%, specificity of 81%, and demonstrated a significant agreement in the clinical diagnosis of depression with the 15-item scale. The 5-item scale is scored by 1 point for a “no” answer on the first question or a “yes” answer for the remaining questions. A score of greater than or equal to 2 is a positive screen for depression (see the images below). [17]
Patients who do not have suicidal or homicidal ideation can be referred for outpatient therapy . Individuals who have the above ideations should be hospitalized and a psychiatric consult should be initiated during the hospitalization.
DEPRESSION -MEDICATION
SSRI-1st line therapy due to less side effects and decrease risk for overdose.
SNRI- result in more side effects
Effexor( causes sedation)
Cymbalta( not recommended for older adults, individuals with glaucoma, liver problems, or those who abuse alcohol) Barkley, 2021
Patients should be educated on the medication prescribed and be remined that it can take up to 6 weeks to see results.
ANXIETY
Anxiety is a condition that presents with excessive thoughts of fear and worry about a situation. Needless to say, we all have experienced anxiety whether it be from a dread exam, presentation , or other activities. It becomes problematic when there is interference with day to day activities. Anxiety is most often caused by stressors.
Psychological manifestations include tension, fears, apprehension, and difficulty concentrating.
Individuals may have the following symptoms: sleep disturbances, irritability, depression, feeling overwhelmed, headache, tachycardia, and unpleasant GI/GU symptoms (Barkley, 2021).
Anxiety disorders are the most prevalent psychiatric disorder.
Anxiety may be acute or chronic.
Lack of structure is frequently a contributing factor.
Planned-time activities tend to bind anxiety.
Anxiety can be self-generating, as the symptoms reinforce the reaction.
Avoidance of the triggers can lead to reinforcement of the anxiety.
DEPRESSION KEY POINTS
Depression is a common disorder that involves depressed mood and/or near-complete loss of interest or pleasure in activities that were previously enjoyed; somatic (eg, weight change, sleep disturbance) and cognitive manifestations (eg, difficulty concentrating) are common.
Depression may markedly impair the ability to function at work and to interact socially; risk of suicide is significant.
Sometimes depressive symptoms are caused by general medical disorders (eg, thyroid or adrenal gland disorders, benign or malignant brain tumors, stroke, AIDS, Parkinson disease, multiple sclerosis) or use of certain medications (eg, corticosteroids, some beta-blockers, interferon, some illicit drugs).
Diagnosis is based on clinical criteria; general medical disorders must be ruled out by clinical evaluation and selected testing (eg, CBC; electrolyte, TSH, B12 and folate levels).
Treatment involves psychotherapy and usually medications; SSRIs are usually tried first, and if they are ineffective, other medications that affect serotonin, norepinephrine and/or dopamine may be tried.
ANXIETY
Generalized anxiety disorder is characterized by excessive anxiety and worry about a number of activities or events that are present more days than not for ≥ 6 months. The cause is unknown, although it commonly coexists in people who have alcohol use disorder, major depression, or panic disorder. Diagnosis is based on clinical criteria. Treatment includes behavioral interventions, psychotherapy, pharmacotherapy, or a combination.
ANXIETY
To meet DSM-5-TR criteria for GAD, patients must have excessive anxiety and worry about a number of activities or events (eg, work and school performance), occurring more days than not for ≥ 6 months (1).
The worries are difficult to control and must be associated with ≥ 3 of the following:
Restlessness or a keyed-up or on-edge feeling
Easy fatigability
Difficulty concentrating
Irritability
Muscle tension
Disturbed sleep
The psychiatric symptoms must cause significant distress or significantly impair social or occupational functioning. Also, the anxiety and worry cannot be accounted for by substance use or a general medical disorder (eg, hyperthyroidism).
