Q

What are the 3 things that happen in Parkinson’s disease?

A

Degeneration of neurons in basal ganglia (substantia nigra) that produce dopamine
As it progresses presence of cytoplasmic inclusion bodies called lewy bodies
Substantial neurodegeneration occurs in PD before onset of motor symptoms (30-60& degeneration)

Q

Name some common cognitive dysfunctions with PD?

A

Dementia (20-40%)
Bradyphrenia (slowed thinking)
Hallucinations, delusions, psychosis, (L-dopa toxicity)

17
Q

True or False: Depression and Anxiety are common in PD?

A

TRUE: both are common

18
Q

What are some sleep disorders associated with PD?

A

Daytime sleepiness
Insomnia
REM sleep behavior disorder (act out dreams)

19
Q

What is the only accurate way to diagnose PD?

A

Continued observation of evolving clinical signs and symptoms
-No single definitive test or group of tests

20
Q

How many cardinal motor features are necessary to typically make a diagnosis of PD?

A

2/4

21
Q

How can you tell the difference between PD and PD-Plus syndrome?

A

PD affects 1 side more

PD-Plus presents bilaterally (doesn’t respond to L-dopa either)

22
Q

What are the most common causes of death with someone with PD?

A

Cardiovascular disease

Pneumonia (risk of asperation due to dysphagia)

23
Q

What is the “gold Standard for measuring progression of PD”

A

Unified Parkinson’s Disease Rating Scale (UPDRS)

24
Q

Name the 4 parts of UPDRS

A

Mentation, behavior, mood
ADLs
Motor Exam
Complications of drug therapy

25
Q

Describe the Hoehn-Yahr Classification of disability

A

Stage 1 = Minimal/absent unilateral if present
Stage 2 = Minimal bilateral or mid-line involvement, (balance not impaired)
Stage 3 = Impaired righting reflexes, unsteadiness when rising from chair, can live independent
Stage 4 = All symptoms present and severe, standing & walking possible with minA
Stage 5 = Confined to bed or wheelchair

26
Q

What is the focus of medical management of PD?

A

Slow progression using neuroprotective strategies and symptomatic treatment

  • Pharmacological
  • Nutritional
  • Deep brain stimulation
27
Q

What’s the gold standard drug for PD?

A

Levodopa/Carbidopa (Sinemet)

  • Short half life (consistent timing is key)
  • Honeymoon period (dramatic improvements at first)
28
Q

What are some adverse affects of Levodopa?

A

Window is 4-6 years before benefits wear off
Significant number of patients develop dyskinesias, dystonia, and motor fluctuations when this happens (gets 10% worse each year)
On-off phenomenon

29
Q

What’s a dyskinesia?

A

Uncontrolled or involuntary movement

-Occurs at peak dose of L-dopa

30
Q

What is Dystonia?

A

Prolonged involuntary contraction that causes twisting or torsion of body segments (clawing fingers/toes, cramping)

31
Q

What are some common dopamine agonist and what do they do?

A

Requip, Mirapex
Stimulate postsynaptic dopamine receptors
-Linked to increased risk of impulse control disorders

32
Q

What blocks cholinergic function and most benefits moderating tremor and dystonia?

A

Anticholinergics

33
Q

What is the name of the drug that stops an enzyme from breaking down dopamine and is given early on in PD cases to increase dopamine

A

Monoamine Oxidase B Inhibitors (MAO-B)

34
Q

When do you want to time your therapy sessions for a PD patient?

A

When they are during their optimal dose of medication

35
Q

Name something in your diet that can block the effectiveness of L-Dopa?

A

High-Protein

36
Q

When is the optimal time to take Sinemet in correlation with meal time?

A

30 minutes before or 60 minutes after a meal

37
Q

How does deep brain stimulation work?

A

Electrodes placed in the brain block nerve signals that cause symptoms (subthalamic nucleus or globus pallidus)

38
Q

What are some adverse side-effects of DBS?

A

Confusion, headache, speech complication, gait disturbances and falling
