Why are mental retardation and the personality disorders listed on a separate Axis (II)?
to ensure that they receive proper diagnostic consideration relative to the "usually more florid" Axis I disorders
Although it is typically used for mental retardation and personality disorders, Axis II can be used to locate what else?
- below-threshold maladaptive traits
What are the three criteria for a diagnosis of Mental Retardation?
- significantly subaverage intellectual functioning (IQ > 2SD below mean)
- clinically significant functional impairment
- onset before age 18
Apart from morphological signs, such as those associated with Down Syndrome and Fetal Alcohol Syndrome, what are some early behavioral symptoms of Mental Retardation?
- less physically active
- less vocally active
- more compliant
List the four degrees of Mental Retardation severity.
Mild: (IQ 50/55-70) 85% of MR population, difference shows in late childhood, able to reach sixth grade, and work and live independently
Moderate: (IQ 35/40-50/55) 10% of MR population, rarely progress past 2nd grade, and usually require some guidance and supervision for work and life
Severe: (IQ 20/25-35/40) 3-4% of MR population, poor motor skills, limited speech, able to learn hygiene and live communally
Profound: (IQ <20/25) 1-2% of MR population, limited motor & sensory function, require highly structured environment
What are the major etiological factors in Mental Retardation?
- 30% embryonic development (Down's, alcohol/drug use)
- 15-20% environmental issues (nurturance deprivation)
- 10% pregnancy & perinatal issues (fetal trauma or malnutrition, hypoxia)
- 5% hereditary factors (Tay-Sachs, fragile X)
- balance (30-40%) cannot be determined
What is phenylketonuria?
A heritable inability to oxidize the amino acid phenylalanine, found in protein foods. If untreated, causes damage to newborn's nervous system through buildup of abnormal metabolites. Can be treated through diet, resulting in near-normal development if caught early enough.
What is the relative frequency of occurrence of Fragile X syndrome based on sex?
twice as common in males as females
What is the basis of Down's Syndrome, or trisomy-21?
In the fertilized zygote, the 21st pair of chromosomes has an extra chromosome, caused by unequal division of the sperm and egg's share of chromosomes.
What are three types of post-natal causes of Mental Retardation?
- infection, e.g., meningitis and encephalitis
- toxic/nutritional, e.g., lead poisoning and malnutrition
- anoxia, esp. head-injury-based
Define Borderline Intellectual Functioning.
DiffDx (Mental Retardation) is based on lack of significant deficits in adaptive functioning and/or IQ >75
What are the four main areas of the Mental Status Exam, part 1, and their subdivisions?
1. General Appearance
- level of consciousness
2. Motor Activity
- mood (subjective)
