RTS Rett’s Syndrome
Cerebroatrophic Hyperammonemia
??Autism-Dementia-Ataxia-Loss of Purposeful Hand Use Syndrome

Early Onset Phase ??¡° Development stalls or stops.
Rapid Destructive Phase ??¡° The child loses skills (regresses) quickly.?? Purposeful hand movements and speech are usually the first skills lost.
Plateau Phase ??¡° Regression slows, and other problems may seem to lessen or improve. Most people with Rett syndrome spend most of their lives in stage 3.
Late Motor [...]

After appearing to make normal progress, a period of stagnation in development from about the end of the first year, which lasts until regression occurs.
Loss of purposeful hand movements, such as grasping with fingers, reaching for things, or touching things on purpose.
Balance and coordination problems, including losing the ability to walk in many cases
??A regression [...]

PDD-NOS(Pervasive Developmental Disorder – Not Otherwise Specified ) is also called atypical autism or mild autism.
PDD-NOS is a ’subthreshold’ condition in which some – but not all – features of autism or another explicitly identified Pervasive Developmental Disorder are identified. PDD-NOS is often incorrectly referred to as simply “PDD.” The term PDD refers to the [...]

The cause of LKS is unknown. Some experts think there is more than one cause for this disorder. All of the children with LKS appear to be perfectly normal until their first seizure or the start of language problems. There have been no reports of children who have a family history of LKS. Therefore, LKS [...]

The following are the most common indicators of Landau-Kleffner syndrome. However, each individual may experience symptoms differently.

Early signs may be referred to as auditory agnosia, which includes the child:

suddenly having problems understanding what is said.
appearing to have problems with hearing – deafness may be suspected.
appearing to be autistic or developmentally delayed.

Spoken language is eventually affected, [...]

Auditory verbal agnosia, e.g., struggling to find words for familiar objects.
??Difficulty in communicating with speech and language, e.g., problems understanding what is said (receptive dysphasia)
Difficulty in putting thoughts into words (expressive dysphasia).
Difficulty in understanding words spoken or written by others. This symptom is often mistaken for a hearing problem, as the child seems to ignore [...]

The future of a hyperlexic child depends on developing his / her language expression and comprehension skills. Intensive speech and language therapy and early intervention programs can help achieve this objective. The child’s reading skills should be used as a primary means of developing language.
It is important to teach the child appropriate social skills. Providing [...]

Hyperlexia has characteristics similar to autism, behavior disorder, language disorder, emotional disorder, Attention Deficit Disorder, hearing impairment, giftedness or, paradoxically, mental retardation.
To develop effective teaching strategies and more typical childhood development, it is important to differentiate hyperlexia from other disorders. A thorough speech and language pathologist who is familiar with the syndrome of hyperlexia is [...]

Hyperlexia is a syndrome observed in children who have the following characteristics:
A precocious ability to read words, far above what would be expected at their chronological age or an intense fascination with letters or numbers.
Significant difficulty in understanding verbal language
Abnormal social skills, difficulty in socializing and interacting appropriately with people
In addition, some children who are [...]

FXS
fra(X) syndrome
??FRAXA Syndrome
Marker X syndrome
Martin-Bell Syndrome
X-linked mental retardation and macroorchidism

Family history of Fragile X syndrome, especially a male relative
mental impairment, ranging from learning disabilities to mental retardation??
Large testicles (macro-orchidism) after puberty
attention deficit and hyperactivity
Large body size (long face, large ears, flat feet )
autistic behaviors
anxiety and unstable mood
Tendency to avoid eye contact
hyperextensible joints, especially fingers
Large forehead or ears with a prominent jaw

In 1991, scientists discovered the gene (called FMR1 for “Fragile X Mental Retardation – 1″) that causes fragile X. In people with Fragile X, a defect in FMR1 (a “full mutation”) shuts the gene down. Like a defective factory, FMR1 cannot manufacture the protein that it normally makes.Other individuals are carriers: they have a small [...]

Each cell in the body contains forty-six (twenty-three pairs of) chromosomes. These chromosomes consist of genetic material (DNA) necessary for the production of proteins which lead to growth, development and physical and intellectual characteristics.The first twenty-two pairs of chromosomes are the same in males and females. The remaining two chromosomes, X and Y, determine whether [...]

Mutations in the FMR1??gene cause fragile X syndrome.FMR1 is a ??fragile area on the X chromosome.It repeats in the genetic code.Normally, this DNA segment is repeated from 5 to about 40 times.The more repeats, the more likely there is to be a problem.In people with fragile X syndrome, however, the CGG(the DNA segment) segment is [...]

Fragile X syndrome (FXS):the most common cause of inherited mental impairment. This impairment can range from learning disabilities to more severe cognitive or intellectual disabilities. (Sometimes referred to as mental retardation.) FXS is the most common known cause of autism or “autistic-like” behaviors. Symptoms also can include characteristic physical and behavioral features and delays in [...]

Fragile X syndrome is a genetic condition involving changes in the long arm of the X chromosome. It causes a range of developmental problems including learning disabilities and mental retardation.Fragile X is a family of genetic conditions, which can impact individuals and families in various ways. These genetic conditions are related in that they are [...]

if your elementary school child has frequent problems in school or seems unable to make friends, it’s time to consult your pediatrician. These difficulties have many possible causes, but developmental disorders such as Asperger’s syndrome shouldn’t be ruled out. Children whose eccentricities interfere with learning and social development should have a comprehensive evaluation.
Medical care is [...]

Asperger’s Syndrome can not be cured currently .It is lifelong. However, with correct treatment and therapy, many people with Asperger’s can go on to lead normal lives and may even excel in certain areas of occupational functioning.

We can’t tell what causes Asperger’s Syndrome now.Sometimes it appears that there may be a genetic component to this syndrome.But the evidence is not clear.Much more research is needed in this area.

There is no specific treatment for the core symptoms of Asperger syndrome is available, and no cure exists for the disorder.?? because Asperger’s is a relatively new diagnosis in the field of developmental psychology and psychiatry, many treatment approaches are still in the developmental stages and lots of work still needs to be done in [...]

Asperger’s Disorder is sometimes observed in association with general medical conditions. Various nonspecific neurological symptoms or signs may be noted. Here is the DSM-IV??Diagnosis Criteria for??Asperger Syndrome :
A.Qualitative impairment in social interaction, as manifested by at least two of the following:
1.marked impairment in the use of multiple nonverbal behaviors such as eye-to-eye gaze, facial expression, [...]

Asperger Syndrome(Asperger’s Disorder) is a milder variant of Autistic Disorder.The name “Asperger” comes from Hans Asperger, an Austrian physician who first described the syndrome in 1944.People with Asperger Syndrome at first glance may not seem to be related.Those with AS show marked deficiencies in social skills, have difficulties with transitions or changes and prefer sameness. [...]

Prenatal history, fetal development, birth weight, and head circumference at birth are usually normal. Young infants with AS may have breast or bottle feeding difficulties (as a result of sucking difficulties) and muscular hypotonia. Angelman syndrome may be first suspected in the toddlers because of delayed gross motor milestones, muscular hypotonia, and speech delay [Williams, [...]

Always Seen/Consistent (100%)

Developmental delay, functionally severe( failure to match developmental milestones of other children)
Profound speech impairment, none or minimal use of words; receptive and non-verbal communication skills higher than verbal ones
Movement or balance disorder(tremulous movement of limbs, stiffness and jerkiness in limbs), ataxia of gait and/or tremulous movement of limbs
Behavioral uniqueness: any combination of frequent [...]

??The prognosis of Angelman syndrome may include the duration of Angelman syndrome, chances of complications of Angelman syndrome, probable outcomes, prospects for recovery, recovery period for Angelman syndrome, survival rates, death rates, and other outcome possibilities in the overall prognosis of Angelman syndrome. Naturally, such forecast issues are by their nature unpredictable.??Analysis of parent-specific DNA [...]

Angelman Syndrome,short for AS,is an uncommon neurogenetic genetic disorder which was first described by pediatrician Dr. Harry Angelman in 1965. Dr. Harry Angelman is an English physician.He noted that all had a stiff, jerky gait, absent speech, excessive laughter and seizures. Other cases were eventually published but the condition was considered to be extremely [...]

Autism is a complex developmental disability that typically appears during the first three years of life and is the result of a neurological disorder that affects the normal functioning of the brain, impacting development in the areas of social interaction and communication skills. Both children and adults with autism typically show difficulties in verbal and [...]
