Q
Prader-Willi Syndrome
A
A rare genetic disorder in which the paternal genes on chromosome 15 are deleted or unexpressed resulting in a number of physical, mental, and behavioral problems.
-as an infant pt. is very hard to feed; low tone and no interest to eat
2

A
Speech sound errors Hypernasality Flat intonation Imprecise articulation Slow speaking rate Abnormal pitch
7
Q
Prader-Willi Syndrome: Diagnosis
A
- MD may diagnose PWS based on clinical systems
- Genetic testing is used to confirm Dx by identifying chromosomal abnormalities that are characteristic of PWS

- 2nd method is FISH
8
Q
Prader-Willi Syndrome: Treatment and Care
A
- Nutrition and diet modification
- Growth hormone treatment
- Sex hormone treatment
- Therapies: Physical Therapy, Speech Therapy, Occupational Therapy, Developmental Therapy, Nutrition, Mental Health Therapy

- SLP will address speech and language issues and feeding concerns in infancy
9
Q
Prader-Willi Syndrome: Prognosis
A
There is no cure for PWS
Most will require specialized care and supervision throughout their lives
Most adults will reside in residential care facility so eating habits can be monitored
Biggest health risks are complications from obesity
Therapy at home & school will be needed to address cognitive delays, communication, and behavioral delays
10
Q
Danny Walker
A
DW malformation is characterized by a hypoplastic or missing cerebellar vermis, enlarged 4th ventricle, and cyst of the posterior fossa
11
Q
Danny Walker: Prevalence/Prognosis
A
DWM is estimated to occur in >1 in 25,000 live births. It is the most common congenital malformation of the cerebellum
Mortality rates have decreased over time with medical advances
Current estimates suggest 27% of individuals with DWM die early
Overall prognosis is considered to be good and hopeful for those that survive
Best prognostic factor is absence of other congenital defects
12
Q
Danny Walker: History
A
First described by Sutton in 1887 who was performing an autopsy on an infant
Dandy & Blackfan (1914), Dandy (1921) and Taggert and Walker (1942) contributed to classification of DWM by recognizing that there was a blockage of the 4th ventricle which often coincides with hydrocephalus
Dandy-Walker was appointed the name for the disorder in 1954
13
Q
Danny Walker: Associated Problems
A
Hydrocephalus
Seizures
Polycystic Kidneys(cysts are numerous and fluid filed resulting in enlargement of kidneys)
Cardiac Anomalies
Limb and facial abnormalities
Symptoms of increased intracranial pressure (Lethargy, emesis, irritability)
14
Q

- Unsteady gait
- Nystagmus
- Lack of coordination
Occasional:
- Vision Problems
- Hearing Problems
- Cleft lip/palate
15
Q
Danny Walker: Diagnosis
A
Diagnosis can be performed prenatally using ultrasonoghrapy after 18 weeks gestation
Postnatal diagnosis and differentiation from similar disorders is performed using MRI’s, CT scans, and angiographies
16
Q
Danny Walker: Treatment/Management
A
Early treatment included removing the membranes of the posterior fossa (high mortality rates)
Surgical management of DWM currently includes shunting of the 4th ventricle to drain excess CSF buildup (caused by cyst formation)
Anticonvulsive therapy or medication is commonly needed (Phenobarbital most common anti-convulsive drug)
Variable symptoms are treated as needed by (including PT, OT, ST)
17
Q
Fragile X
A
Fragile X Syndrome is an X-linked condition caused by a mutation on the FMR1 gene on the X chromosome. It is usually inherited from a mother who is a carrier of the condition.
Fragile X inheritance is complicated. The FMR1 mutation involves a region of repeating DNA bases on the gene. A FMR1 gene with 55-199 repeats is said to have a “premutation” and a gene with 200 or more repeats is said to have a “full mutation.” Premutations passed on in an egg may or may not develop into full mutations.
18
Q
Fragile X: Prevalence
A
Fragile X is one of the most common genetic disorders
1 in 4000 males
1 in 6000 females
19
Q
Fragile X: History
A
1943, Martin and Bell discovered that a particular form of intellectual disability was X linked
In 1969, Herbert Lubs developed the chromosomal test for Fragile X
In 1991 the FMR1 gene that causes Fragile X was identified
The name Fragile X comes from the broken or fragile appears of the X chromosome
20

Neonatal Abstinence Syndrome (NAS)
Prenatal:
A collection of symptoms found in newborns that have been exposed to addictive drugs in the womb. The drugs pass through the placenta to the infant. Once the infant is born, and is no longer receiving the drug(s), (s)he goes through withdrawal known as NAS
Postnatal:
A collection of symptoms found in the infants who are treated with drugs such as fentanyl or morphine for pain shortly after birth. They subsequently go through withdrawal when the drugs are withdrawn
33
NAS: Epidemiology
- 4.3% of pregnant women ages 15-44 reported using illicit drugs (2003)
- 10% of 4.1 million live births in the US have been exposed to opiates or opioids (heroin, methadone, pain pills)
- NAS is more commonly seen in urban areas
34
NAS: Clinical Features
Signs and symptoms typically begin between 103 days after birth, but may take up to 10 days to appear
Signs and symptoms depend on the drug(s) the mother used, how long she used the drug(s), the amount, and whether the baby was premature or term
```
Blotchy skin coloring (mottling)
Diarrhea
Excessive sucking
Fever
Hyperactive reflexes
Increased muscle tone
Irritability
```
35
NAS: Common Long-term Effects
Boys – increased risk for ADHD and behavioral disorders
Girls – increased risk for mood disorders
Both – increased risk for mental retardation and learning impairments
36
NAS: Diagnostic Criteria
Toxicology Screen:
- Meconium/hair
- Urinalysis/blood
NAS Scoring System – May help determine when to start, titrate, or terminate therapy
- Finnegan – Most common
- Lipsitz
- Modified scales per institution
37
NAS: Treatment
Management of NAS:
- Swaddling
- Rocking the infant
- Reducing noise and lights
- Breastfeeding unless contraindicated
- Team: ST, OT, PT, MD, Nursing, Mental Health Professionals, Social workers
Drug Management of NAS:
- Opioids – used for opioids and polydrug withdrawal
- Phenobarbital – used for polydrug withdrawal (most common)
- Methadone – used for opioid withdrawal
- Morphine – used for polydrug withdrawal, helps control seizures
38
Williams Syndrome
Williams syndrome is caused by the deletion of genetic material from chromosome 7. The loss of 1 of 2 copies of elastin protein in chromosome 7 is often associated with the cardiovascular and musculoskeletal issues seen in patients.
39
Williams Syndrome: Prevalence
- 1 in every 10,000 births
- Equal male to female ration
- Proportionate across race
- An estimated 20,000-30,000 individuals in the U.S. have WS
- Unlikely for other family members to have WS but if the person who has WS plans to have children, the child has a 50% chance of also having the diagnosis
40
Williams Syndrome: History
-First reported in 1961 by Dr. J.C.P. Williams who wrote about four patients who had similar disorders and facial features. A year later, Dr. A.J. Beuren reported 3 new patients with similar presenting characteristics. Therefore, the full name of WS is Williams-Beuren syndrome.
Similarities among patients with Drs. Williams and Beuren:
- Cardiovascular disease
- Learning disabilities and developmental delay
- Facial features
41
Williams Syndrome: Clinical Features
```
Small upturned nose

44
Williams Syndromes: Other Associated Issues
Williams syndrome is also sometimes called:
Elfin syndrome – inappropriate to use. Adult stature is slightly smaller than average and facial features become more apparent with age
Cocktail Party syndrome – inappropriate to use. Clients have excellent speech, appear to have strong social skills, fixated eye contact, and extreme friendliness. Many people with WS prefer talking to older individuals rather than peers.
45
Williams Syndrome: Treatment

- Early intervention is key
- People with SMS can expect to accomplish many of things their "typical" peers do—attend school, achieve in their outside areas of interest, be successfully employed, even move away from their family home
- Need a significant amount of support from their families and from school, work, and residential service providers to achieve these goals
- Appear to have a normal life expectancy, but no supporting research

Laundau-Kleffner
Characterized by the sudden or gradual onset of aphasia in an otherwise typically developing child
112
Laundau-Kleffner: Prevalence
Around 160 cases have been reported between 1957-1990, though exact prevalence is difficult to ascertain due to frequent misdiagnosis

Around 160 cases have been reported between 1957-1990, though exact prevalence is difficult to ascertain due to frequent misdiagnosis
114
Laundau-Kleffner: History
- First identified in 1957 by Dr. William M. Landau and Dr. Frank R. Kleffner
- Dr. Kleffner headed the Central Institute for the Deaf in St. Louis, MO, an institution that provided services to children with hearing impairment and children with aphasia.
- Kleffner began noting children who developed acquired aphasia with a clearly epileptic EEG after a period of normal development

- Kleffner began noting children who developed acquired aphasia with a clearly epileptic EEG after a period of normal development
116
Laundau-Kleffner: Diagnosis
Landau-Kleffner Syndrome is diagnosed through presence of infantile acquired aphasia, along with abnormal spike-and-wave brainwaves revealed through an EEG scan indicative of epileptic seizures.
117
Laundau-Kleffner: Diagnosis
Landau-Kleffner Syndrome is diagnosed through presence of infantile acquired aphasia, along with abnormal spike-and-wave brainwaves revealed through an EEG scan indicative of epileptic seizures.
118
Laundau-Kleffner: Prognosis
- Prognosis is characterized by immense variation.
- Aphasia may last for days or years. Recovery may be full, or some language difficulties may persist.
- However, most will outgrow seizures by the age of 15, and early intervention often leads to better outcomes.
119
Velocardial Facial Syndrome (VCFS)
Missing a small part of chromosome 22 at the q11 region.
Unknown cause of deletion, but this is one of the most frequent chromosome defects in newborns.
- 10% inherited
- Most “sporadic”
10% of individuals with VCFS do not have a deletion in the chromosome 22q11 region.
- Other chromosome defects
- Maternal diabetes
- Fetal alcohol syndrome
- Prenatal exposure to Accutane®
120
VCFS: Prevalence
- Many do not present with obvious anomalies at birth.
- 1/3 of individuals do not have CHD or overt clefts of the palate.
- Other associated problems may go unnoticed as they require special procedures (ultrasound, MRI).
- 1 in 1600 to 1 in 2000
- *DiGeorge is a sequence of events that occur not a syndrome (VCSF is a syndrome w/genetic markers)
121
VCFS: History
1955, Eva Sedlačková
-First known cases appear in the medical literature which described a number of cases of children with hypernasal speech and reduced facial animation.
1968, Angelo DiGeorge
-Described the association of thymic aplasia, hypoparathyroidism, and congenital heart disease in children who rarely survived to adulthood so that the full range of clinical features could not be observed (behavioral and cognitive manifestations).
1968, Strong
-Published a report of a single family with multiple affected members that was the first publication to confirm as a genetic disorder that involved both physical manifestations and cognitive and behavioral disorders.
1976, Japanese literature
-Called conotruncal anomaly face syndrome (CAFS).
1978, Robert Shprintzen
The delineation of velo-cardio-facial syndrome as a specific and distinct inherited genetic disorder occurred
122
VCFS: Features
Many of the findings in VCFS are very common among other multiple anomaly syndromes
Most common/consistent features:
- behavioral
- cognitive
- vascular
BDs & LDs will not be evident until later in life and may go unrecognized for many years.
Important to recognize the psychiatric manifestations of this syndrome at all developmental stages
123
VCFS: Cognitive Issues
Children perform worse than would be expected by their cognitive level on tasks requiring:
- shifts of attention
- cognitive flexibility
- working memory
- visuospatial and numerical abilities
When present, intellectual disabilities are usually relatively mild
The cognitive profile:
- Relative strengths in the areas of reading, spelling, and rote memory
- Relative weaknesses in the areas of visuospatial memory and arithmetic
Changes with development
-Usually a decline in IQ as move into adulthood
124
VCFS: Common Speech Problems
Delayed development of speech and language skills
Hypernasal speech due to velopharyngeal dysfunction
Articulation disorders
Voice disorders and laryngeal anomalies
Language impairment
Pragmatic and social skills difficulties
125
VCFS: Possible Concomitant Disorders
```
ADHD
Oppositional defiant disorder
Specific and social phobias
Generalized anxiety disorder
Separation anxiety disorder
Obsessive-compulsive disorder
Major depressive disorder and dysthymia
Autism spectrum
```
By late adolescence and early adulthood, this picture seems to change as up 1/3 of the patients with VCFS develop psychotic disorders mostly resembling schizophrenia and schizoaffective disorder”
126
VCFS: Diagnosis
- Blood tests and tests to examine for immune system problems
- X-ray – to produce images of internal tissues, bones, and organs onto film.
- Echocardiography - Evaluate the structure and function of the heart
- Fluorescence in situ hybridization (FISH) studies – A blood test is ordered to look for a deletion in the chromosome 22q11.2 region.
- If a 22q11.2 deletion is detected in a child, then both parents are offered the FISH test to see if this deletion is inherited.
127
VCFS: Treatment
Specific treatment for VCFS is determined based on the following:
- Child's age, overall health, and medical history
- The extent of the disease
- Child's tolerance for specific medications, procedures, or therapies
- Expectations for the course of the disease
- Parent opinion or preference
Heart defects will be evaluated by a cardiologist.
A plastic surgeon and a speech pathologist evaluate cleft lip and/or palate.
Speech and gastrointestinal specialists evaluate feeding difficulties.
Immunology evaluations should be performed in all children with this deletion.
-In severe cases where immune system function is absent, bone marrow transplantation is required.
Many will benefit from early intervention to help with muscle strength, mental stimulation, and speech problems
128
VCFS: Prognosis
- Small minority will not survive the first year of life.
- Majority will have a treatable heart condition and immune system disorder that will not be significant enough to interfere with survival.
- Most progress into adulthood with normal growth.
129
Angelman
Both Angelman Syndrome and PraderWilli Syndrome occur as a result of severe reductions of a gene on chromosome 15.
What’s the difference?
In AS, the abnormality is on the maternally derived chromosome 15,
and for PWS, the abnormality is on the paternally derived chromosome 15.
130
Angelman: History
- 1965: Dr. Harry Angelman (left) described 3 children with similar characteristics of a stiff, jerky gait; absent speech; excessive laughter; and seizures. He called them “Puppet Children.”
- 1987: Dr. Ellen Magenis identified children with PraderWilli features with additional features of seizures and severe developmental delay. Genetic testing identified presence of microdeletions on maternallyderived chromosome 15.
131
Angelman: Consistent Clinical Features
Developmental delay
Movement or balance disorder (usually ataxia)
Behavioral uniqueness (frequent smiling, easily excitable, handflapping movements)
Speech impairment (none or minimal use of words)
132
Angelman: Frequent Clinical Features
Delayed, disproportionate head
growth (microcephaly by 2 yrs.)
Seizures (before 3 yrs.)
Abnormal EEG (in first 2 yrs.)
133
Angelman: Associated Clinical Features
```
Flat occiput
Occipital groove
Protruding tongue
Tongue thrusting; suck/swallowing disorders
Feeding problems
Prognathia
Wide mouth
Widespaced teeth
Frequent drooling
Strabismus
Hypopigmented skin
Hyperactive LE deep tendon reflexes
Uplifted, flexed arm position
Widebased gait
Increased sensitivity to heat
Abnormal sleepwake cycles/ diminished need for sleep
Excessive chewing/mouthing behaviors
Attraction to/fascination with water and/or crinkly items such as paper
Abnormal food related behavior
Obesity (in older children)
Scoliosis
Constipation
```
134
Angelman: Diagnosis
- As results from severe reduction of the UBE3A gene on the maternally derived chromosome 15.
- If clinical features are present, genetic testing should be performed.
- Most common diagnosis is between 2 5 years of age. This is because this is when the characteristic behaviors become most evident.
- Other common misdiagnoses include Autism Spectrum Disorders and Cerebral Palsy.
135
Angelman: Treatment
- Consistent behavioral intervention and stimulation to over come developmental challenges
- Behavioral treatment programs have been shown to benefit abnormal sleep/wake cycles
- ABA has been found to be an effective instructional method
- Anticonvulsant medication may be necessary to treat seizures
136
Angelman: SLP Treatment
- Handflapping motions are thought to result from inability to communicate effectively
- Conversational speech will never develop in highest functioning individuals
- Individuals with AS have much better comprehension than expression
- Severe seizures may inhibit reaching first stages of communication, such as establishing eye contact
- Most common aim for treatment is teaching sign language
- Other options include picture based communication boards or speech generating devices
- Carryover is key! SLP must collaborate with parents and other professionals in order to help the child learn to functionally communicate
137
Angelman: Prognosis
- Mobility issues become a more predominant concern as the child ages, and is often associated with concerns of obesity.
- If severe ataxia is present, the child may lose his or her ability to walk if ambulation is not encouraged.
- Scoliosis may develop in adolescence, especially if the individual is non ambulatory.
- Lifespan is not dramatically shortened.
138
Angelman: Cure
- A cure for AS has been found in mice!
| - With a recently received grant, the Foundation for Angelman Syndrome Therapeutics is beginning their first human study
139

Asperger's Syndrome: Common Activities/Interests
Has an “obsessive” interest that causes: exclusion of other activities, is narrow or limited to a very specific topic, that may be uncommon for age especially in terms of amount and type of facts the child knows, and that may overrule his or her desire for social relationships.
Child may also lack interactive play.
148
Asperger's Syndrome: Diagnosis
- Difficult (Several screenings but no single standardized tool)
- Currently, must meet DSM-IV criteria Made through observation and developmental Hx

- MDs and psychiatrists- medicines for related
Applied Behavioral Analysis (ABA)
Skinner- 1930s
-This program is for younger children with an autism spectrum disorder. Uses a one-on-one teaching approach that reinforces the practice of various skills. The goal is to get the child close to normal developmental functioning.
Treatment and Education of Autistic and Related Communication Handicapped Children (TEACCH)
Erick Schopler- 1970s
-It uses picture schedules and other visual cues that help the child work independently and organize and structure their environments. Do not expect children to achieve typical development with treatment.

Pivotal Response Training (PRT)
Koegel & Koegel-1970s
-Child directed (or child centered), goal of PRT is to produce positive changes in the pivotal behaviors, leading to improvement in communication skills, play skills, social behaviors and the child's ability to monitor his or her own behavior. by focusing on critical, or "pivotal," behaviors that affect a wide range of behaviors
Floortime (DIR)
Greenspan-1980s
-is to help the child reach six developmental milestones that contribute to emotional and intellectual growth: self-regulation and interest in the world, intimacy or a special love for the world of human relations, two-way communication, complex communication, emotional ideas, emotional thinking
