Down Syndrome

Children with Down syndrome have been included in regular academic

classrooms in schools across the country In some instances they are

integrated into specific courses while in other situations students are

fully included in the regular classroom for all subjects The degree of

mainstreaming is based in the abilities of the individual but the trend is

for full inclusion in the social and educational life of the community

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

12

Autism Etiology

Yeast infections

Intolerance to specific food substances

(Gluten intolerance (Leaky Gut SyndromeCasein intolerance causing

intestinal permeability and allowing improperly digested peptides to enter

the bloodstream and cross the blood-brain barrier which may mimic

neurotransmitters and result in the scrambling of sensory input Ive also

heard Leaky Gut Syndrome described as lack of the beneficial bacteria

that aids digestion and that the resulting matter in the bloodstream invokes

an unnecessary immune reaction)

Phenolsulphertransferase (PST) deficiency--theory that some with autism are

low on sulphate or an enzyme that uses this called phenol-

sulphotransferase-P This means that they will be unable to get rid of amines

and phenolic compounds once they no longer have any use for them These

then stay in their body and may cause adverse effects even in the brain

Andrew Wakefield (born 1956) is a British former

work regarding the MMR vaccine and its claimed connection

with autism and inflammatory bowel disease Wakefield was the lead author

of a 1998 study published in The Lancet which reported bowel symptoms in

twelve children diagnosed with autism spectrum disorders to which the authors

suggested a possible link with the MMR vaccine Though stating We did not

prove an association between measles mumps and rubella vaccine and the

syndrome described the paper tabulated parental allegations and adopted these

allegations as fact for the purpose of calculating a temporal link between receipt

of the vaccine and the first onset of what were described as behavioural

symptomsldquo

Use it or lose it If you do not drive specific brain functions functional

loss will occur

Use it and improve it Therapy that drives cortical function enhances that

particular function

Specificity The therapy you choose determines the resultant plasticity and

function

repetition

Intensity matters Induction of plasticity requires the appropriate amount

of intensity

AcquiredTraumatic Brain Injury

one therapy can augment the attainment of similar behaviors

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

12

Autism Etiology

Yeast infections

Intolerance to specific food substances

(Gluten intolerance (Leaky Gut SyndromeCasein intolerance causing

intestinal permeability and allowing improperly digested peptides to enter

the bloodstream and cross the blood-brain barrier which may mimic

neurotransmitters and result in the scrambling of sensory input Ive also

heard Leaky Gut Syndrome described as lack of the beneficial bacteria

that aids digestion and that the resulting matter in the bloodstream invokes

an unnecessary immune reaction)

Phenolsulphertransferase (PST) deficiency--theory that some with autism are

low on sulphate or an enzyme that uses this called phenol-

sulphotransferase-P This means that they will be unable to get rid of amines

and phenolic compounds once they no longer have any use for them These

then stay in their body and may cause adverse effects even in the brain

of a 1998 study published in The Lancet which reported bowel symptoms in

twelve children diagnosed with autism spectrum disorders to which the authors

suggested a possible link with the MMR vaccine Though stating We did not

prove an association between measles mumps and rubella vaccine and the

syndrome described the paper tabulated parental allegations and adopted these

allegations as fact for the purpose of calculating a temporal link between receipt

of the vaccine and the first onset of what were described as behavioural

symptomsldquo

Neuroplasticity amp Rehabilitation

Use it or lose it If you do not drive specific brain functions functional

loss will occur

Use it and improve it Therapy that drives cortical function enhances that

particular function

Specificity The therapy you choose determines the resultant plasticity and

function

Repetition matters Plasticity that results in functional change requires

repetition

Intensity matters Induction of plasticity requires the appropriate amount

of intensity

AcquiredTraumatic Brain Injury

Neuroplasticity amp Rehabilitation Time matters Different forms of plasticity take place at different times

during therapy

Salience matters It has to be important to the individual

Age matters Plasticity is easier in a younger brain but is also possible in an

adult brain

Transference Neuroplasticity and the change in function that results from

one therapy can augment the attainment of similar behaviors

Interference Plasticity in response to one experience can interfere with the

acquisition of other behaviors

Autism Etiology

Yeast infections

Intolerance to specific food substances

(Gluten intolerance (Leaky Gut SyndromeCasein intolerance causing

intestinal permeability and allowing improperly digested peptides to enter

the bloodstream and cross the blood-brain barrier which may mimic

neurotransmitters and result in the scrambling of sensory input Ive also

heard Leaky Gut Syndrome described as lack of the beneficial bacteria

that aids digestion and that the resulting matter in the bloodstream invokes

an unnecessary immune reaction)

Phenolsulphertransferase (PST) deficiency--theory that some with autism are

low on sulphate or an enzyme that uses this called phenol-

sulphotransferase-P This means that they will be unable to get rid of amines

and phenolic compounds once they no longer have any use for them These

then stay in their body and may cause adverse effects even in the brain

of a 1998 study published in The Lancet which reported bowel symptoms in

twelve children diagnosed with autism spectrum disorders to which the authors

suggested a possible link with the MMR vaccine Though stating We did not

prove an association between measles mumps and rubella vaccine and the

syndrome described the paper tabulated parental allegations and adopted these

allegations as fact for the purpose of calculating a temporal link between receipt

of the vaccine and the first onset of what were described as behavioural

symptomsldquo

Neuroplasticity amp Rehabilitation

Use it or lose it If you do not drive specific brain functions functional

loss will occur

Use it and improve it Therapy that drives cortical function enhances that

particular function

Specificity The therapy you choose determines the resultant plasticity and

function

Repetition matters Plasticity that results in functional change requires

repetition

Intensity matters Induction of plasticity requires the appropriate amount

of intensity

AcquiredTraumatic Brain Injury

Neuroplasticity amp Rehabilitation Time matters Different forms of plasticity take place at different times

during therapy

Salience matters It has to be important to the individual

Age matters Plasticity is easier in a younger brain but is also possible in an

adult brain

Transference Neuroplasticity and the change in function that results from

one therapy can augment the attainment of similar behaviors

Interference Plasticity in response to one experience can interfere with the

acquisition of other behaviors

Children with Down syndrome have been included in regular academic

classrooms in schools across the country In some instances they are

integrated into specific courses while in other situations students are

fully included in the regular classroom for all subjects The degree of

mainstreaming is based in the abilities of the individual but the trend is

for full inclusion in the social and educational life of the community

Children with Down syndrome have been included in regular academic

classrooms in schools across the country In some instances they are

integrated into specific courses while in other situations students are

fully included in the regular classroom for all subjects The degree of

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

Autism Etiology

Yeast infections

Intolerance to specific food substances

(Gluten intolerance (Leaky Gut SyndromeCasein intolerance causing

intestinal permeability and allowing improperly digested peptides to enter

the bloodstream and cross the blood-brain barrier which may mimic

neurotransmitters and result in the scrambling of sensory input Ive also

heard Leaky Gut Syndrome described as lack of the beneficial bacteria

that aids digestion and that the resulting matter in the bloodstream invokes

an unnecessary immune reaction)

Phenolsulphertransferase (PST) deficiency--theory that some with autism are

low on sulphate or an enzyme that uses this called phenol-

sulphotransferase-P This means that they will be unable to get rid of amines

and phenolic compounds once they no longer have any use for them These

then stay in their body and may cause adverse effects even in the brain

Haugen OH Hovding G Eide GE Biometric measurements of the eyes in teenagers and

young adults with Down syndromeActa Ophthalmol Scand 2001 Dec79(6)616-25

Thinning of the corneal stroma may

account for the steeper cornea and the

high frequency of astigmatism in Down

syndrome due to lower corneal rigidity

It may also be of etiological importance

to the increased incidence of

keratoconus in Down syndrome

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

Fragile X-associated tremorataxia syndrome

reported in 33-40 of men older than 50 years and less

frequently (4-8) in older women with premutations in the

fragile X mental retardation (FMR1) gene

Clinical features (FXTAS) incontinence impotence cerebellar

hypotension severe intention tremor and other signs of

neurodegeneration (brain atrophy memory loss and dementia

anxiety depression and irritability) Premature ovarian failure

in 25 of women with premutations this represents a 30-fold

increase compared with the general population

Autism

Factors such as younger age of diagnosis broadening of diagnostic criteria improvements in the availability

of services and better awareness of the disorder have all been attributed to the change in autism

prevalence However recent epidemiological studies indicated that while these factors do account for a

portion of the change they cannot account for all of the increase alone

Autism

Do Parents cause their children to be autistic There are autistic children born to parents who do not fit the autistic parent personality pattern

Parents who do fit the description of the supposedly pathogenic parent have normal non-autistic

children

Frequently siblings of autistic children are normal

Autistic children are behaviorally unusual from the moment of birth

There is a consistent ratio of three or four boys to one girl

Virtually all cases of twins reported in the literature have been identical with both twins

afflicted

Autism can occur or be closely simulated in children with known organic brain damage

The symptomatology is highly unique and specific

There is an absence of gradations of infantile autism which would

create blends from normal to severely afflicted

12

Autism Etiology

Yeast infections

Intolerance to specific food substances

(Gluten intolerance (Leaky Gut SyndromeCasein intolerance causing

intestinal permeability and allowing improperly digested peptides to enter

the bloodstream and cross the blood-brain barrier which may mimic

neurotransmitters and result in the scrambling of sensory input Ive also

heard Leaky Gut Syndrome described as lack of the beneficial bacteria

that aids digestion and that the resulting matter in the bloodstream invokes

an unnecessary immune reaction)

Phenolsulphertransferase (PST) deficiency--theory that some with autism are

low on sulphate or an enzyme that uses this called phenol-

sulphotransferase-P This means that they will be unable to get rid of amines

and phenolic compounds once they no longer have any use for them These

then stay in their body and may cause adverse effects even in the brain

work regarding the MMR vaccine and its claimed connection

with autism and inflammatory bowel disease Wakefield was the lead author

of a 1998 study published in The Lancet which reported bowel symptoms in

twelve children diagnosed with autism spectrum disorders to which the authors

suggested a possible link with the MMR vaccine Though stating We did not

prove an association between measles mumps and rubella vaccine and the

syndrome described the paper tabulated parental allegations and adopted these

allegations as fact for the purpose of calculating a temporal link between receipt

of the vaccine and the first onset of what were described as behavioural

Use it or lose it If you do not drive specific brain functions functional

loss will occur

Use it and improve it Therapy that drives cortical function enhances that

particular function

Specificity The therapy you choose determines the resultant plasticity and

function

Repetition matters Plasticity that results in functional change requires

repetition

Intensity matters Induction of plasticity requires the appropriate amount

of intensity

AcquiredTraumatic Brain Injury

one therapy can augment the attainment of similar behaviors

IOM Report No Link Between Vaccines and Autism

By Michelle Meadows

There is no link between autism and the

measles-mumps-rubella (MMR) vaccine or the

vaccine preservative thimerosal according to a

report released by the Institute of Medicines

(IOM) Immunization Safety Review

Committee

VL et al Early thimerosal exposure and neuropsychological outcomes at 7

to 10 years N Engl J Med 2007 Sep 27357(13)1281-92

Our study does not support

a causal association between early

exposure to mercury from thimerosal-containing vaccines and immune

globulins and deficits in neuropsychological functioning at the age of 7 to

10 years

Andrew Wakefield (born 1956) is a British former

surgeon and researcher best known for his discredited

work regarding the MMR vaccine and its claimed connection

with autism and inflammatory bowel disease Wakefield was the lead author

of a 1998 study published in The Lancet which reported bowel symptoms in

twelve children diagnosed with autism spectrum disorders to which the authors

suggested a possible link with the MMR vaccine Though stating We did not

prove an association between measles mumps and rubella vaccine and the

syndrome described the paper tabulated parental allegations and adopted these

allegations as fact for the purpose of calculating a temporal link between receipt

of the vaccine and the first onset of what were described as behavioural

symptomsldquo

AcquiredTraumatic Brain Injury

Neuroplasticity amp Rehabilitation

Use it or lose it If you do not drive specific brain functions functional

loss will occur

Use it and improve it Therapy that drives cortical function enhances that

particular function

Specificity The therapy you choose determines the resultant plasticity and

function

Repetition matters Plasticity that results in functional change requires

repetition

Intensity matters Induction of plasticity requires the appropriate amount

of intensity

AcquiredTraumatic Brain Injury

Neuroplasticity amp Rehabilitation Time matters Different forms of plasticity take place at different times

during therapy

Salience matters It has to be important to the individual

Age matters Plasticity is easier in a younger brain but is also possible in an

adult brain

Transference Neuroplasticity and the change in function that results from

one therapy can augment the attainment of similar behaviors

Interference Plasticity in response to one experience can interfere with the

acquisition of other behaviors
