Poor Quality of Care for Older Adults with Mental Disorders

• Increased risk for inappropriate medication treatment (Bartels, et al., 1997, 2002)

> 1 in 5 older persons given an inappropriate prescription (Zhan, 2001)

• Less likely to be treated with psychotherapy (Bartels, et al., 1997)

• Lower quality of general health care and associated increased mortality (Druss, 2001)

What is most commonly diagnosedMental disorder among older adults???

2:1 females to males

Specific anxiety disorders include the following:

general anxiety disorder (GAD)panic attacks

phobias obsessive compulsive disorder post-traumatic stress disorder

Anxiety:

-- Necessary part of life! (transitional:adjustment)

-- Warns of danger-- Can stimulate and lead to productivity

Persistent anxiety …not good

Transitional Anxiety

FACTORS COMPLICATING THE DIAGNOSIS OF ANXIETY IN OLDER ADULTS

Comorbidity of Mental Illness-- Older Adults

unrealistic or excessive worry not related to a particular problem or event

Related to vague fears about losing control, fear of failure, fear of death

• fatigue • muscle tension • trouble sleeping through the night panic attacks• difficulty concentrating on a task • feeling irritable or on edge

1) Chronic anxiety that persists for more than 6 months2) be accompanied by decreases in activities or some sort of

impairment3) be caused by more than one worry (ex: intense worry over

financial matters or a medical illness alone, even with all the associated symptoms, does not mean someone has GAD)

General anxiety disorder (GAD)

Panic Attacks (???)sudden, distinct episodes of intense anxiety

• usually a hx of attacks when younger• relatively rare for attacks to begin for the first time after age 55

(usually milder with fewer panic symptoms and less agoraphobia:

fear of open spaces)Phobias (.5%)

specific phobia: fear of a specific person, animal, place, object, event, or situation that results in symptoms of anxiety.

social phobias: fears associated with social situations. The usual fear is of behaving inappropriately in a certain situation and feeling

incompetent or embarrassed.

obsessive compulsive disorder (1.5%)having persistent thoughts (obsessions) that cause anxiety, and then

behaving (compulsions) in ways to decrease the anxiety (< than 1 hr a day).

post-traumatic stress disorder (???)experienced (either as a witness or a victim) a traumatic event and

reacted with feelings of fear and helplessness.

“The Aviator” Draws Attention to Anxiety Disorders in Older AdultsUntil recently, anxiety disorders were believed to decline with age

Depression

Reactive-Exogenous triggered by an obvious event

Endogenous No trigger No obvious event

•Anhedonia (experience pleasure)•Weight gain or loss•Hypersomnia, insomnia• Fatigue, loss of energy• feelings of worthlessness guilty• difficulty concentrating

Clinical Depression ~ 5%:

• Depressed mood most of the day, nearly everyday • Loss of pleasure in daily activities • Significant weight loss or gain • Change in mobility (slowing down or nervous gestures)• Feelings of worthlessness, self reproach, excessive guilt • Diminished ability to concentrate • Suicidal thoughts

Steffens et al. (2000) : depression in older adults was 4.4% in women and 2.7% in men

When depression occurs in late life:

1. relapse of an earlier depression

2. If first time occurrence may be triggered by another illness, hospitalization, or placement in a nursing home

3. Unlike the onset of depression in younger adults depression is thought to be a psychological disorder triggered by specific life stressors (loss of loved one)

Attitudes Of Older Adults Towards Depression

68% of Americans aged 65 and over know little or almost nothing about depression

Only 38% of Americans aged 65 and over believe

that depression is a "health" problem

If suffering from depression, older Americans are more likely than any other group to "handle it

themselves." Only 42% would seek help from a health professional.

National Mental Health Association, 1996

Peak suicide rates: goes up continuously for men / at midlife for women, then declines

1/3 of older men saw their primary care physician in the week before completing suicide; 70% within the prior month

• Among the Most Common Disorders– Dementia – ***Depression (as high as 50%!!!)– Anxiety Disorders and Psychotic Disorders

(Burns & Taube, 1990, 1991, Rovner et al., 1990)
