Dual Diagnosis:A Brief Overview

Psychiatric Disorders in Mentally Retarded Adults

same range of behavioral and emotional problems as non-disabled adults

Overshadowing

MENTAL RETARDATION IS NOT MENTAL ILLNESS

Rates of Psychiatric Disorders in Mentally Retarded Adults

Higher for adults than for children under age 10 Higher rates in mild vs. severe mental retardation Equal rates for men and women Equal rates for different cultural groups Studies show rates 4 – 6 times higher than in non-

disabled population

Difficulties specific to some individuals with mental retardation

difficulties with verbal expression/ nonverbal

Difficulties understanding their own emotional responses

Suffering in silence – the person who does not act out emotional distress

What is Wrong?

People who are higher functioning (and verbal) can usually answer this question – the standard way to investigate emotional problems

Decreases in intelligence = diminished ability to express problems verbally

Emotional expression is shown in behavior

Detective Work

Use of intuition and hunches

Detectives on behalf of our consumers

Communicating with Behavior

Externally directed behaviors

aggression

irritability

disorganized speech

Internally directed behaviors

depression

stress/nervousness

withdrawal

Internal behaviors – difficult to detect External behaviors –difficult to interpret

Negative behaviors serve a function: Attempt to communicate Expression of frustration Attention seeking (or communication about the need

for more attention) Accomplish consumer’s goals

Sorting It All Out

Gather information while consumer is stable Baseline data – observations of typical behavior Family history – interviews with family members

Observe changes Triggers Feelings Goal of behavior Symptom picture

Baseline Data

Aspects to consider: Eye contact Response to social contact Speed of response (rapid or slow) Typical mood (happy, sad, moody?) Tone of voice Body language -- physical stance Usual interests or pastimes

Family History

Obtain a family history of mental health issues Ask about:

Depression Alcoholism or strict abstinence Manic depression Stress / anxiety/ nervous breakdowns Odd personality traits Domestic violence

Observing Change

Rule out medical causes Look for triggers – changes in routine, unusual

events Ask consumer about feelings Ask yourself what the person is accomplishing

with this behavior Observe their behavior for symptoms

Diagnosis

It is an inexact way of categorizing people

Useful as a method of communicating with other professionals a way to explore your hunches, to provide yourself

with direction

Arriving at a diagnosis

Work from a big perspective toward details begins with hunches

Work from details toward an overview begins with observation

The Big Perspective

Ask yourself general questions:

Is he/she not making sense (more so than usual?) Is the person stressed? Anxious? Nervous? Does he/she seem blue, irritable, moody? Did the person just experience an event that would

have been traumatizing?

Working with intuition

Rely on your intuition as a guide Do extra reading :

Diagnostic and Statistical Manual for Mental Disorders- Fourth Edition, Text Revision (DSM-IV-TR)

Observation of behavior

Work from the perspective of changes you observe in your consumer

Use baseline data as a comparison to see how behavior has changed

Consult DSM-IV-TR
