The First Account of PD
“Shaking palsy” first
described by James
Parkinson in 1817– Involuntary tremor
– Lessened muscular power
– Tendency to bend forward
– Tendency to pass from walking to
running pace
– Senses and intellect uninjured

Evolution of Lewy Body Pathology
PD-related Lewy body pathology evolves in predictable stages. According to the staging system of Braak,
Lewy bodies (LB) first form within in the olfactory bulb and dorsal motor nucleus of the vagal nerve (Stage
1). In Stages 2 and 3, LB pathology expands from these induction sites into additional brain stem nuclei
(e.g. locus coeruleus and substantia nigra) and then into the amygdala. In Stages 5 to 6, the pathology
extends into the cerebral cortex. Clinical symptoms arise during Stages 4 to 6, when the pathology involves
significant regions of the substantia nigra and related brain areas.

A New Definition of PD:
A 3-Phase DiseasePhase 1 Preclinical PD PD-specific pathology
assumed to be present
• Asymptomatic, but will need to be
supported by:
• Molecular markers (α-synuclein, DJ-1,
LRRK2, parkin, PINK1 mutations)
• Imaging markers (transcranial
sonography, PET, SPECT, MIBG SPECT,
α-synuclein imaging)
Phase 2 Premotor PD Presence of early nonmotor
signs and symptoms due to
extranigral PD pathology
• Premotor features commonly occur before
the emergence of motor signs (olfaction
abnormalities; constipation; cardiac
involvement; neurobehavioral symptoms)
Phase 3 Motor PD PD pathology involves
substantia nigra leading to
dopamine deficiency sufficient
to cause classic motor
manifestations followed by
later nonmotor features
• Traditionally diagnosable symptoms
(bradykinesia, tremor, rigidity)
• May progress to include late PD features
(dysautonomia, sensory symptoms, cognitive
decline)

Idiopathic PD ~ 85% of all PS
Neuroleptic-induced parkinsonism (DIP) 7-9%
MSA ~2.5%
PSP ~ 1.5%
Vascular Parkinsonism ~3%
MPTP,CO,MN,recurrent head trauma is extremely rare

Epidemiology of PD
PD is the second most common neurodegenerative disorder
after Alzheimer’s disease
Affects 0.3% of worldwide population
– 1%-2% of people aged >60 years
Approximately 1 million people have PD in the US
Prevalence predicted to almost double in US from 2005-2030 in
individuals aged >50 yrs

Causes of PD
PD is heterogeneous
– Unlikely there is a single etiology
Contributing factors may include:
– Environment
– Genetics
– Combination of both
Abnormal aggregation of α-synuclein may play a role in the
development of PD

Genetics and PD
PD is primarily a sporadic or idiopathic disorder
The Human Genome Project has helped to better define the gene
association
– Up to 20% of patients with PD have the familial variety
– Causal and susceptibility genes discovered for PD
– Monogenic forms account for only a very small portion of patients with PD

DaTScan: Evolving Imaging That May Aid in
Diagnosis of PD
DaTScan™ (Ioflupane I 123 Injection), is a radiopharmaceutical
agent recently approved by the FDA for striatal dopamine transporter
(DaT) visualization using single photon emission-computed
tomography (SPECT) imaging.
DaTScan differentiates between patients with and without a
dopaminergic deficit.
DaTScan is a potential adjunct in the diagnosis of Parkinsonian
symptoms.
DaTScan does not differentiate Parkinsonian Syndromes

Anticholinergics
Dopaminergic depletion→cholinergic overactivity
Initially used in the 1950s
Effective mainly for tremor and rigidity
Common agents (Start low, go slow):
– Trihexyphenidyl: 2-15 mg/day
– Benztropine: 1-8 mg/day
– Ethopropazine: 10-200 mg/day
Side effects:
– Dry mouth, sedation, delirium, confusion,
hallucinations, constipation, urinary retention

Amantadine
Antiviral agent; PD benefit found accidentally
Tremor, bradykinesia, rigidity & dyskinesias
Exact mechanism unknown; possibly:– enhancing release of stored dopamine
– inhibiting presynaptic reuptake of catecholamines
– dopamine receptor agonism
– NMDA receptor blockade
Side effects —autonomic, psychiatric
200-300 mg/day

Carbidopa/Levodopa
(Sinemet)
Most effective drug for parkinsonian symptoms
First developed in the late 1960s; rapidly became the
drug of choice for PD
Large neutral amino acid; requires active transport
across the gut-blood and blood-brain barriers
Rapid peripheral decarboxylation to dopamine without a
decarboxylase inhibitor (DCIs: carbidopa,
benserazide)
Side effects: nausea, postural hypotension,
dyskinesias, motor fluctuations

COMT Inhibitors
• Newer class of antiparkinsonian drugs: tolcapone,
entacapone (Opicapone only available in Europe)
• MOA similar to dopa decarboxylase inhibitors
• Potentiate LD: prevent peripheral degradation by
inhibiting catechol O-methyl transferase
• Reduces LD dose necessary for a given clinical effect
• Helpful for both early and fluctuating Parkinson’s disease
• May be particularly useful for patients with “brittle” PD,
who fluctuate between off and on states frequently
throughout the day

Motor Fluctuations
“Wearing off”: re-emergence of symptoms prior to the next scheduled levodopa (LD) dose
“On/off” phenomenon: unpredictable fluctuations of periods of good mobility and function followed by periods of poor symptom control
Delayed-“on” responses: dose takes longer to improve symptoms than previously
Dose failure: dose does not provide usual improvement in symptoms
![Page 58: PD and Medication: What’s New?€¦ · PD and Medication: What’s New? Fernando Pagan, MD Professor and Vice Chairman, Dept. of Neurology Director, Movement Disorders Program Medical](https://reader034.vdocument.in/reader034/viewer/2022042121/5e9ae41f49309e427b0a1ece/html5/thumbnails/58.jpg)

CONCLUSION
• We have multiple medications to help improve quality of life of individuals with PD.
• “Polypharmacy” is common but it may help with some of the motor complications and minimize extremes of more than one medication.
• Every patient is different, what works for one may not necessarily work for another.
• Team effort approach between patient and physician to optimize therapy and quality of life.
• Medications are only part of a multi-disciplinary approach necessary in order to treat Parkinson’s disease.
