Huntingtonrsquos

disease (HD)

Inherited Neurodegenerative

Disorder

Mutation in the Htt gene

50 chance of inheritance if either

parent has the mutated gene

Onset ndash 30-70 years of age

Incidence ~57 per 100000 in

Australia

HD is a fatal complex and

severely debilitating disease

for which there is no cure

There is a gradual loss of neural cells and

muscle cells

So gradual loss of cognitive physical

and emotional function

HISTORY

Paracelsus (1527) 16th century

1872 recognized as a disease for first time

Dr George Huntington (New York) published

ldquoOn Choreardquo in The Medical and Surgical

Reporter of Philadelphia

22 years - Sole publication of just a few paragraphs

was entirely anecdotal and unreferenced

1993 the huntingtin protein was inextricably linked

to the huntingtin gene (Htt or IT15) and to the

disease

HOW

Mutation in the Htt gene

Htt gene has C A G repeat in

exon 1

Normal = 9-36 repeats

Mutant gene = 40 -

250

Produces an abnormal protein

with a polyglutamine tract

Length of CAG repeat

correlates with age of onset

(can be as young as 2)

ABNORMAL PROTEIN -

NEURAL LOSS

protein-protein interactions

With normal proteins

Aggregates in cytoplasm

Inclusion bodies in nucleus

bullVesicular Transport Defective

bullGene transcription and expression

affected

NORMAL PROTEIN In nucleus cell body dendrites of many nerve cells

Transcription vesicle transport cytoskeletal anchoring and pro-survival properties

Timed loss of neurons with abnormal HD protein

RESULT

Loss of neurons in specific brain regions

In the striatum (basal ganglia) causing

loss of movement control

In the cortex and cerebellum - causing

Psychosis and Dementia

Loss of brain volume

Striatal neurons

Coordinate complicated motor and

visual and thinking tasks

- Computer games

- Driving a car

Striatal neurons linked to cortical

neurons

Striatum is also

affected in

Parkinsonrsquos disease

Muscle Movement Disorders - CHOREA hyperkinetic - dystonia and rigidity hypokinetic initiating voluntary movements

Chorea Atrophy

Summary of Symptoms Neural Cell Death

Cognitive (Neural)

Symptoms

Muscle Cell Deficits

Motor (Muscular) Symptoms

STRIATUM Loss GABAergic medium spiny neurons

Loss of Executive Function (Planning)

Decreased fibre diameter Reduce neural input

Muscle Atrophy - Gait Dysfunction

CORTEX Pyramidal neurons

Loss of Short Term Memory (Dementia)

Fibre type switching

Chorea

Decreased Creatine Kinase (energy stores)

Psychiatric disturbances (delusionsparanoiaanxiety)

Decreased Creatine Kinase (energy stores)

Saccadic eye movements

Loss of Brain Neurotrophic factor BDNF

Depression Mitochondrial dysfunction - energy

Loss of Balance - Vestibular

Huntingtonrsquos disease is not just a disease of the CNS

Peripheral effects of HD

Weight loss

(Adapted from van der Burg (2009) Lancet Neurology 8 765-774

Need to treat all defects using multi-disciplinary intervention

No treatment is

currently available that

slows alters or

reverses the disease

NEUROGENESIS

AS THERAPY

Replacing old or lost neurons with new

neurons

NEUROGENESIS

Upregulated by Mental and Physical

Exercise

Physical stimulation (exercise)

upregulates production of endogenous

stem cells within the brain

Cognitive stimulation increases stem cell

survival and integration of new neurons

Together increased production and

survival of neural stem cells in mouse

models of HD

Environmental enrichment - combined

use of mental and physical stimulation to

effect neurological changes

HEROs (Huntingtons Enrichment Rehabilitation Optimisation Scheme)

AIM Implement Environmental Enrichment Program (HEROS)

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

Huntingtonrsquos

disease (HD)

Inherited Neurodegenerative

Disorder

Mutation in the Htt gene

50 chance of inheritance if either

parent has the mutated gene

Onset ndash 30-70 years of age

Incidence ~57 per 100000 in

Australia

HD is a fatal complex and

severely debilitating disease

for which there is no cure

There is a gradual loss of neural cells and

muscle cells

So gradual loss of cognitive physical

and emotional function

HISTORY

Paracelsus (1527) 16th century

1872 recognized as a disease for first time

Dr George Huntington (New York) published

ldquoOn Choreardquo in The Medical and Surgical

Reporter of Philadelphia

22 years - Sole publication of just a few paragraphs

was entirely anecdotal and unreferenced

1993 the huntingtin protein was inextricably linked

to the huntingtin gene (Htt or IT15) and to the

disease

HOW

Mutation in the Htt gene

Htt gene has C A G repeat in

exon 1

Normal = 9-36 repeats

Mutant gene = 40 -

250

Produces an abnormal protein

with a polyglutamine tract

Length of CAG repeat

correlates with age of onset

(can be as young as 2)

ABNORMAL PROTEIN -

NEURAL LOSS

protein-protein interactions

With normal proteins

Aggregates in cytoplasm

Inclusion bodies in nucleus

bullVesicular Transport Defective

bullGene transcription and expression

affected

NORMAL PROTEIN In nucleus cell body dendrites of many nerve cells

Transcription vesicle transport cytoskeletal anchoring and pro-survival properties

Timed loss of neurons with abnormal HD protein

RESULT

Loss of neurons in specific brain regions

In the striatum (basal ganglia) causing

loss of movement control

In the cortex and cerebellum - causing

Psychosis and Dementia

Loss of brain volume

Striatal neurons

Coordinate complicated motor and

visual and thinking tasks

- Computer games

- Driving a car

Striatal neurons linked to cortical

neurons

Striatum is also

affected in

Parkinsonrsquos disease

Muscle Movement Disorders - CHOREA hyperkinetic - dystonia and rigidity hypokinetic initiating voluntary movements

NEUROGENESIS

Upregulated by Mental and Physical

Exercise

Physical stimulation (exercise)

upregulates production of endogenous

stem cells within the brain

Cognitive stimulation increases stem cell

survival and integration of new neurons

Together increased production and

survival of neural stem cells in mouse

models of HD

use of mental and physical stimulation to

effect neurological changes

Huntingtonrsquos

disease (HD)

Inherited Neurodegenerative

Disorder

Mutation in the Htt gene

50 chance of inheritance if either

parent has the mutated gene

Onset ndash 30-70 years of age

Incidence ~57 per 100000 in

Australia

HD is a fatal complex and

severely debilitating disease

for which there is no cure

There is a gradual loss of neural cells and

muscle cells

So gradual loss of cognitive physical

and emotional function

HISTORY

Paracelsus (1527) 16th century

1872 recognized as a disease for first time

Dr George Huntington (New York) published

ldquoOn Choreardquo in The Medical and Surgical

Reporter of Philadelphia

22 years - Sole publication of just a few paragraphs

was entirely anecdotal and unreferenced

1993 the huntingtin protein was inextricably linked

to the huntingtin gene (Htt or IT15) and to the

disease

HOW

Mutation in the Htt gene

Htt gene has C A G repeat in

exon 1

Normal = 9-36 repeats

Mutant gene = 40 -

250

Produces an abnormal protein

with a polyglutamine tract

Length of CAG repeat

correlates with age of onset

(can be as young as 2)

ABNORMAL PROTEIN -

NEURAL LOSS

protein-protein interactions

With normal proteins

Aggregates in cytoplasm

Inclusion bodies in nucleus

bullVesicular Transport Defective

bullGene transcription and expression

affected

NORMAL PROTEIN In nucleus cell body dendrites of many nerve cells

Transcription vesicle transport cytoskeletal anchoring and pro-survival properties

Timed loss of neurons with abnormal HD protein

RESULT

Loss of neurons in specific brain regions

In the striatum (basal ganglia) causing

loss of movement control

In the cortex and cerebellum - causing

Psychosis and Dementia

Loss of brain volume

Striatal neurons

Coordinate complicated motor and

visual and thinking tasks

- Computer games

- Driving a car

Striatal neurons linked to cortical

neurons

Striatum is also

affected in

HD is a fatal complex and

severely debilitating disease

for which there is no cure

There is a gradual loss of neural cells and

muscle cells

So gradual loss of cognitive physical

and emotional function

HISTORY

Paracelsus (1527) 16th century

1872 recognized as a disease for first time

Dr George Huntington (New York) published

ldquoOn Choreardquo in The Medical and Surgical

Reporter of Philadelphia

22 years - Sole publication of just a few paragraphs

was entirely anecdotal and unreferenced

1993 the huntingtin protein was inextricably linked

to the huntingtin gene (Htt or IT15) and to the

disease

HOW

Mutation in the Htt gene

Htt gene has C A G repeat in

exon 1

Normal = 9-36 repeats

Mutant gene = 40 -

250

Produces an abnormal protein

with a polyglutamine tract

Length of CAG repeat

correlates with age of onset

(can be as young as 2)

ABNORMAL PROTEIN -

NEURAL LOSS

protein-protein interactions

With normal proteins

Aggregates in cytoplasm

Inclusion bodies in nucleus

bullVesicular Transport Defective

bullGene transcription and expression

affected

NORMAL PROTEIN In nucleus cell body dendrites of many nerve cells

Transcription vesicle transport cytoskeletal anchoring and pro-survival properties

Timed loss of neurons with abnormal HD protein

RESULT

Loss of neurons in specific brain regions

In the striatum (basal ganglia) causing

loss of movement control

In the cortex and cerebellum - causing

Psychosis and Dementia

Loss of brain volume

Striatal neurons

Coordinate complicated motor and

visual and thinking tasks

- Computer games

- Driving a car

Striatal neurons linked to cortical

neurons

Striatum is also

affected in

Parkinsonrsquos disease

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

HISTORY

Paracelsus (1527) 16th century

1872 recognized as a disease for first time

Dr George Huntington (New York) published

ldquoOn Choreardquo in The Medical and Surgical

Reporter of Philadelphia

22 years - Sole publication of just a few paragraphs

was entirely anecdotal and unreferenced

1993 the huntingtin protein was inextricably linked

to the huntingtin gene (Htt or IT15) and to the

disease

HOW

Mutation in the Htt gene

Htt gene has C A G repeat in

exon 1

Normal = 9-36 repeats

Mutant gene = 40 -

250

Produces an abnormal protein

with a polyglutamine tract

Length of CAG repeat

correlates with age of onset

(can be as young as 2)

ABNORMAL PROTEIN -

NEURAL LOSS

NORMAL PROTEIN In nucleus cell body dendrites of many nerve cells

Transcription vesicle transport cytoskeletal anchoring and pro-survival properties

Timed loss of neurons with abnormal HD protein

RESULT

Loss of neurons in specific brain regions

In the striatum (basal ganglia) causing

loss of movement control

In the cortex and cerebellum - causing

Psychosis and Dementia

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

RESULTS STILL TO COME

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small

sample size

Multidisciplinary rehabilitation intervention in early-mid stage HD patients appears

to slow symptoms of disease progression

Patients with early-mid stage Huntingtonrsquos disease can participate in continuous multidisciplinary

rehabilitation as an adjunct to pharmaceutical therapy without adverse effects

Participants demonstrated high levels of compliance

Participants exhibited cognitivephysicalfunctional benefits - encouraging given the small
