What is the primary treatment principle for Parkinson's disease?
Replace dopamine
Which drug acts like dopamine in the brain?
Levodopa
Which of the following is a major symptom of Parkinson Disease?
Tremor
What is the cause of Parkinson Disease?
Impaired neurons in the substantia nigra
Which age group is most commonly affected by Parkinson Disease?
Over 65
Which medication is the most effective agent for improving movement in Parkinson's disease?
Levodopa
Which medication is commonly used for initial treatment in younger patients with Parkinson's disease?
Amantadine
Which medication is FDA-approved to treat hallucinations and delusions in Parkinson's disease?
Pimavanserin
Which symptom can precede motor symptoms and may appear much earlier in the disease process of Parkinson's disease?
Constipation
What are the major symptoms of Parkinson Disease?
The major symptoms of Parkinson Disease are tremor, rigidity, akinesia/bradykinesia, and postural instability.
What is the role of dopamine in Parkinson Disease?
Dopamine is a neurotransmitter that allows smooth, coordinated function of body muscles and movement. In Parkinson Disease, the death or impairment of dopamine-producing cells leads to motor symptoms.
Why is tremor often the first noticeable symptom of Parkinson Disease?
Tremor is often the first noticeable symptom of Parkinson Disease because it appears when the hand is not moving, such as when a person's hand is resting in their lap.
What is the role of droxidopa (Northera) in the treatment of Parkinson's disease?
Droxidopa is indicated for orthostatic hypotension in Parkinson's disease patients.
What are the primary treatment principles for Parkinson's disease?
The primary treatment principles for Parkinson's disease include replacing dopamine with levodopa, giving dopamine agonists, and using other drugs for specific symptoms.
What is levodopa and how does it work in the brain?
Levodopa is a precursor to dopamine that becomes dopamine in the brain. It helps replace the dopamine deficiency in Parkinson's disease.
What are some non-motor symptoms that can precede motor symptoms in Parkinson's disease?
loss of smell (anosmia), constipation, sleep difficulties, low mood/depression, and orthostasis
What are some potential complications of using clozapine as an antipsychotic in Parkinson's disease patients?
agranulocytosis, seizures, and metabolic complications such as increased cholesterol and blood glucose
What are some potential side effects of rapid withdrawal of levodopa or dopamine agonists in Parkinson's disease patients?
a condition similar to neuroleptic malignant syndrome (NMS), which is a life-threatening condition
What are some alternative treatment options for tremor-predominant Parkinson's disease in younger patients?
centrally-acting anticholinergic, amantadine, or selective monoamine oxidase (MAO) inhibitor
Parkinson disease usually develops after the age of 50.
False

True
Tremor is the most common symptom of Parkinson disease.
True
True or false: Droxidopa (Northera) is a drug indicated for the treatment of Parkinson's disease?
False
True or false: Levodopa is a precursor to dopamine that becomes dopamine in the brain?
True
True or false: Benztropine is a drug used to treat orthostatic hypotension in Parkinson's disease patients?
False
True or false: Non-motor symptoms of Parkinson's disease can appear much earlier in the disease process than motor symptoms?
True
True or false: Patients with Parkinson's disease have a high incidence of depression?
True
True or false: Clozapine is the preferred antipsychotic for Parkinson's disease due to a low risk of movement disorders?
False
True or false: Rapid withdrawal of levodopa or dopamine agonists can lead to a life-threatening condition similar to neuroleptic malignant syndrome?
True
Match the following medications with their primary usage in treating Parkinson's disease:
Droxidopa (Northera) = Treating orthostatic hypotension Levodopa = Replaces dopamine in the brain Dopamine agonist = Acts like dopamine Benztropine = Treating resting tremor
Match the following terms with their description in the context of Parkinson's disease treatment:
Dopamine = Neurotransmitter that is replaced or mimicked in primary treatment Orthostatic hypotension = Condition treated by Droxidopa (Northera) Resting tremor = Symptom treated by Benztropine Levodopa = Dopamine precursor used in Sinemet
Match the following treatment principles with their corresponding explanations:
Giving a precursor to dopamine = This substance becomes dopamine in the brain Giving a dopamine agonist = This substance acts like dopamine Giving other drugs for specific symptoms = For example, benztropine for resting tremor Primary treatment = Replace dopamine
Match the following Parkinson Disease symptoms with their descriptions:
Tremor = Often the first noticeable symptom, usually starts in one hand or foot Rigidity = Occurs in legs, arms, trunk and face, leading to a mask-like face Akinesia/Bradykinesia = Lack of or slow start in movement Postural Instability = Imbalance, leading to falls
Match the following terms related to Parkinson Disease with their meanings:
Dopamine = Neurotransmitter that allows smooth, coordinated function of body muscles and movement Substantia nigra = Part of the brain where neurons die or become impaired in Parkinson Disease Phenothiazines = Class of drugs that can worsen Parkinson Disease symptoms Abnormal Involuntary Movement Scale (AIMS) = Used to measure involuntary movements from medications
Match the following additional symptoms of Parkinson Disease with their descriptions:
Micrographia = Small, cramped handwriting Shuffling walk, stooped posture = Movement characteristics often seen in patients Muffled speech, drooling, dysphagia = Speech and swallowing difficulties Depression, anxiety = Psychological symptoms, with psychosis possible in advanced disease
Match the following drugs with their primary usage in Parkinson's disease:
Carbidopa/Levodopa = Most effective agent for improving movement Pimavanserin = Treatment of hallucinations and delusions Apomorphine = Treatment of severe freezing episodes Metoclopramide = Can accumulate in elderly patients
Match the following psychiatric conditions with their treatment options in Parkinson's disease:
Depression = SSRIs, SNRIs, tricyclic antidepressants, dopamine agonist pramipexole Psychosis = Quetiapine, Clozapine, Pimavanserin Off Episodes = High doses of PD drugs and various combinations Movement Disorders = Carbidopa/Levodopa, dopamine agonists
Match the following drugs with their side effects in Parkinson's disease:
Quetiapine = Metabolic complications, increased cholesterol and blood glucose Clozapine = Risk of agranulocytosis, seizures and other serious complications Levodopa or dopamine agonists = Risk of condition similar to neuroleptic malignant syndrome if rapidly withdrawn Anticholinergics = Considerable side effects, difficult to use in elderly patients
Match the following non-motor symptoms with their occurrence in Parkinson's disease process:
Loss of smell = Can precede motor symptoms and may appear much earlier Constipation = Can precede motor symptoms and may appear much earlier Sleep difficulties = Can precede motor symptoms and may appear much earlier Low mood/depression = Can precede motor symptoms and may appear much earlier
