Parkinson's Disease

James Parkinson’s original 1817 describe “shaking palsy” now
called parkinsons disease.

Parkinson's disease is a progressive degenerative disorder of the
central nervous system.

Idiopathic Parkinson's disease is caused by the progressive loss of
dopaminergic neurons in the substantia nigra and nigrostriatal
pathway of the midbrain and the presence of lewy bodies.

The hallmark physical signs of Parkinson's disease are tremor,
rigidity and bradykinesia.

Poor postural reflexes are sometimes included as the fourth
hallmark sign. When postural reflexes are inadequate, patients
may fall if they are pushed even slightly forward or backward, or if
they are standing in a moving vehicle such as a bus or train.
Parkinson’s disease is a disorder of the basal ganglia
Degeneration of
dopamine neurons
in substantia nigra.
These neurons
usually project to
the striatum.
Tremor, slowness of movement
(bradykinesia),
trouble initiating movement
(akinesia), rigidity.
Affects 1/250 over 40; 1/100
over 65.
EPIDEMIOLOGY
Parkinson’s disease effect over 1% of ll
peoples>50years old.
 5-10%of patients with PD present at age
<40years.
 There is a similar incidence in males and
females.
 All ethnic group are equally effected.

CLINICAL MENIFESTATION OF PD
Cardinal menifestation:




Resting tremor
Rigidity
Akinesia/bradykinesia
Postural instability
Secondary manifestations:

Cognitive dysfunction
Ocular dysfunction
Facial and oropharyngeal dysfunction
Musculoskeletal deformities
Pain and sensory symptoms

PD is a progressive neurological condition causing


Rx does not alter progression of disease


Physical disability
Mental disability
helps to alleviate various symptoms
helping to live independent & productive lives
Ideal management

Social Rehabilitation
Health Education
Lack of specialists
 Population


 No.
Urban
Rural
of available specialists
~160 million
35%
65%
< 100
Lack of awareness amongst healthcare providers

General practitioners managing PD patients

Not confident in their diagnosis
 Inadequate Rx prescribed
 Not updated in newer available Rx modalities
 Unable to handle the labile course of disorder /
complications / Rx SE
 Focus only on pharmacological Rx
Lack of awareness amongst healthcare seekers (1)

? Nature of illness



Consider it to be a part of natural ageing process and
do not seek medical advice
Incorporated in the integrated family system
? Best Rx provider



GP
Medical Internist
Psychiatrist
Neurosurgeon
Neurologist
Lack of awareness amongst healthcare seekers (2)

? Rx options

Expected Rx outcome


Pharmacological
Surgical
Rehabilitation
A “cure”
Unaware that Rx alleviate symptoms which help live an independent &
productive life, Overall improves the QOL
Rx limitations


Drug resistance
Side effect – involuntary movements, on-off fluctuations, dystonic
phenomenon
Lack of “Holistic Approach”

“Treatment Bias”




Only pharmacological Rx offered
Surgical Rx - Limited facilities, costly
Lack of recent advanced technologies
Lack of Coordinated Multidisciplinary Care

Physiotherapy
Occupational therapy
Speech therapy
Psychiartic / psychological therapy
Social / occupational rehabilitation
Health awareness
Compliance (1)

Cost

Rx Expensive
33% population below national poverty line
1% of national budget allotted for health
Health insurance almost non-existent

Low national health priority
Infectious diseases of priority


No health insurance
Lack of awareness


Importance of Regularity of Rx
Long-term Rx
Rx limitations – “not curative”, no reversibility
Rx side-effects
Rx resistence
Compliance (2)

Inconsistent Logistics



65% live in rural areas
Inconsistent availability
Socio-cultural beliefs



No cure No Rx
Alternative Rx – faith healer, hakim, homeopath, masseur
Normal ageing process & easily incorporated in the integrated family
system
Summary

Not a national health priority
 Few to non-existing facilities for management of
chronic diseases
 Lack of specialists
 Lack of availability of recent Rx advancements
 Lack of multidisciplinary input
 Lack of rehabilitative facilities
 Lack of sustained logistics
 Poor socioeconomic conditions
 Lack of public health education & awareness

Easy incorporation in the existing family system
