Final Practice Questions Flashcards
Include Exam 2 in Studying (54 cards)
What is dementia?
A disease process involving progressive decline in cognitive function and memory loss
Over 170 types of dementias exist, with Alzheimer’s disease being the most common.
How is dementia treated?
Pharmacotherapy and person-centred care
Medications can help with chemical changes but not structural changes.
What are cholinesterase inhibitors?
Medications like donepezil, rivastigmine, galantamine that stop the breakdown of acetylcholine
They show modest improvement in cognition, function, and behavior.
What is the role of memantine in treating Alzheimer’s Disease?
Blocks the pathological effects of abnormal glutamate release
It is indicated for moderate to severe Alzheimer’s and shown to slow cognitive decline.
What is the main function of the thalamus?
Major relay centre for almost all sensory information prior to reaching the cerebrum.
What are the four major lobes of the cerebrum?
- Frontal
- Parietal
- Temporal
- Occipital
What is the function of the cerebellum?
Coordinates fine motor movements, maintains balance and posture.
What are the symptoms of Parkinson’s Disease?
- Tremor
- Rigidity
- Akinesia
- Bradykinesia
- Postural instability
What is the primary cause of Parkinson’s Disease?
Degeneration of dopamine-producing neurons in the basal ganglia.
What does the blood-brain barrier do?
Limits movement of substances into the CNS, allowing only lipophilic substances to cross.
What is the role of the basal nuclei?
Regulates starting and stopping of skeletal muscle movements and assists with cognitive functions.
What does the reticular activating system (RAS) do?
Promotes wakefulness and alertness; inhibits sleepiness and drowsiness.
What are common risks associated with acute care admissions for patients with dementia?
- Delay to diagnosis
- Increased incidence of delirium, falls, and infections
- Increased length of stay
- Increased mortality
What are dopamine agonists?
Medications that directly stimulate dopamine receptors
Examples include bromocriptine and pramipexole.
Fill in the blank: Alzheimer’s disease accounts for approximately _______ of all dementias.
70%
What is the primary function of the hypothalamus?
Major visceral control centre for hunger, thirst, body temperature, and regulation of sympathetic functions.
What characterizes Multiple Sclerosis (MS)?
Demyelination of neurons affecting both sensory and motor branches.
What are the early signs of Multiple Sclerosis?
- Muscle weakness
- Visual disturbances
- Paresthesia
- Bladder control problems
What are some causes of seizures?
- Infectious diseases
- Trauma
- Metabolic disorders
- Vascular disease
True or False: All convulsions are seizures.
True
How do seizures typically progress?
They have a beginning (aura), middle (ictus), and end (post-ictal period).
What is the ‘on-off’ phenomenon in Parkinson’s Disease?
A long-term adverse effect where symptoms fluctuate between control and uncontrolled states.
What are the main functions of the limbic system?
- Emotional states
- Learning
- Memory
What is the primary neurotransmitter involved in memory and cognition affected by Alzheimer’s?
Acetylcholine
