6. Parkinson’s disease
Parkinson’s disease (PD) is a progressive
neurodegenerative condition
•The second most common progressive neurodegenerative disorder
diagnosis is primarily clinical, based on history and
examination
7. History
• James Parkinson (1755-1824),
• Remembered for the disease state named after him by Charcot
8. History of Parkinson’s Disease
• His small but famous publication, "Essay on the Shaking Palsy",
appeared in 1817, 7 years before his death in 1824.
10. IPD (Idiopathic Parkinson disease )
• Idiopathic Parkinson Disease (also referred to as primary
or classical Parkinson disease), is a progressive
neurodegenerative disorder associated with decrease
dopamine in parts of the brain (nigrostriatal neurons).
• Affecting about 0.4% people>40y
• 1% people>65y
• 10%people>80y
11. Secondary PD:
Age - the most important risk factor
Positive family history
Male gender
Environmental exposure: Herbicide and pesticide
exposure, metals (manganese, iron), well water, farming,
rural residence, wood pulp mills; and steel alloy
industries
Race
Life experiences (trauma, emotional stress, personality
traits such as shyness and depressiveness)?

caffeine intake in case-control studies.
12. • Normally Dopamine & Ach neurotransmitters work together to enable motor neurons
to refine voluntary movement
• Parkinson's results from the degeneration of dopamine-producing nerve cells in
the brain, specifically in the substantia nigra and locus coeruleus
• Clients have lost 80% or more of their dopamine-producing cells by the time
symptoms appear
17. • 1-2% of population over age 65 years
• 85% sporadic, 10-15% familial clustering and <5% monogenic inheritance
• Advancing age is important risk factor
• Twin studies report similar concordance of 10-20% for monozygotic and
dizogtic twins.
• May be less prevalent in China and other Asian countries, and in African-
Americans.
• Prevalence rates in men are slightly higher than in women; reason
unknown, though a role for estrogen has been debated.
18. incidence and prevalence
•PD is estimated to affect 100–180 in 100,000 people
•annual incidence of 4–20 per 100,000
•rising prevalence with age
•higher prevalence and incidence of PD in males
•depression affects around 40% of PD patients

Difficulty with daily activities such as writing, shaving, using

26. Non-motor Symptoms
• depression.
• Behavior—indirectly, e.g., a result of dementia, depression.
• Thinking-slowed reaction time and executive dysfunction
• Sensation—impaired sense of smell
• Excessive daytime sleep, insomnia, and sleep disturbances
• Vision problems
• Impaired proprioception
• Excessive salivation
• Excessive sweating
• Loss of bowel and/or bladder control
• Anxiety, depression, isolation
• Slow response to questions
• Cognitive impairment (mood swings...dementia)
• Weight loss
• Incontinence
• Constipation
27.
28. Investigation & Diagnosis
• History
• Symptoms: Must have two or more of the primary symptoms, one of
which is a resting tremor or bradykinesia)
• Progression of symptoms
• CT-Scan
• MRI
• Autopsy
29. Features that support diagnosis
• Characteristic resting tremor
• Narrow-based gait with flexed/ stooped posture
• Reduced arm swing with tremor
• Sustained and significant levodopa effect
• Unilateral symptom onset
30. Goals of therapy:
• Minimize disability
• Maintain quality of life.
• Pt & family education & involvement in decisions.
• In patients with mild disease →drug not recommended if
disabilities haven’t developed.
32. EXERCISE AND PHYSICAL THERAPY :
• Exercise will not slow the progression of akinesia,
rigidity, or gait disturbance, but it can prevent or alleviate
some secondary orthopedic effects of rigidity and flexed
posture such as
• shoulder, hip, and back pain
• and it may also improve function in some motor tasks..
33. • Brisk walks,
• swimming,
• water aerobic exercises
• are particularly useful.
35. Nutrition:
• Elderly patients with chronic illness are at risk for poor nutrition and
weight loss.
• Prompt recognition and management of this problem is important to
avoid loss of bone and muscle mass.
• No specific diet influences the course of Parkinson disease (PD),
• A high fiber diet and adequate hydration help manage the
constipation of PD.
• Large, high-fat meals should be avoided.
36. Psychological Counseling:
The emotional and psychological needs of the patient and
family should be addressed.
. Support for the caregiver is particularly important. Referral
of the patient and/or family to a psychologist or
psychiatric social worker experienced in dealing with
chronic illness may be appropriate in some cases.
37. Prognosis
• Parkinson's disease has no common prognosis with symptoms that vary for
each patient
• It is a disease that remains for the patients life time
• Symptoms can get worse over time
41. • People are much less likely
to get Parkinson's Disease if
they:
• Smoke cigarettes
• Drink alcohol
• Have high cholesterol
• Drink too much coffee.
PD is a progressive neurodegenerative condition resulting from the death of the dopamine-containing cells of the substantia nigra.
There is no consistently reliable test to distinguish PD from other conditions with similar symptoms. Diagnosis is primarily clinical, based on history and examination.
PD is a common, chronic, progressive neurological condition, estimated to affect 100–180 per 100,000 of the population (between 6 and 11 people per 6000 of the general population in the UK). It has an annual incidence of 4–20 per 100,000, and there is a rising prevalence with age and a higher prevalence and incidence in males.
Depression affects around 40–50% of people with PD. There are difficulties in diagnosing mild depression in people with PD as the clinical features of depression overlap with the motor features of PD.
Vision problems include double vision, contrast sensitivity, spacial reasoning, and oculomotor control.
