1+
If someone is hyporeflexic, but still has a response what would their reflex grading scale be?
100
Parenchyma of the brain
Pia mater, arachnoid mater, parts of the duramater
Ependymal and choroid plexus
Skull except periosteum
What is pain insensitive in the brain?
100
thalamus, hypothalamus, pineal gland, pituitary gland
What is the diencephalon
100
CT or PET Scan - whole body to ID cancer, biopsy
What is Diagnostics used for Brain tumours?
200
more males than females → except meningiomas, which occur more frequently in women
What sex is more likely to get a brain tumour?
200
a series of involuntary, rhythmic muscular contractions in response to a rapid muscle stretch reflex
What is clonus?
200
pain caused by abnormal neural activity that arises secondary to injury, disease, or dysfunction of the nervous system
Central pain - caused by CNS dysfunction, such as ischemic stroke, phantom limb pain
Peripheral pain - caused by damage to peripheral nerves
burning, deep pain
What is neuropathic pain
200
Problems with vision
What is the presentation of a brain tumour in the Occipital Lobe
200
without treatment: 1 month
with treatment: < 1 year
What is the prognosis of Brain Tumours?
300
Primary arise from the CNS and brain itself, secondary metastasize to the brain
What is the difference between primary and secondary brain tumours?
300
inability to passively flex neck due to increased tone in neck musculature
What is nuchal rigidity
300
pain that is triggered by chemical, mechanical or thermal stimuli (noxious stimuli)
Somatic pain (MSK) - localized and sharp pain
Visceral pain - dull, diffuse and deep pain
What is nociceptive pain
300
Problems with auditory, memory, or speech - aphasia
What is the presentation of a brain tumour in the Temporal Lobe
300
C1-C3 joints, ligaments, suboccipital muscles, Lev scap, trapezius, SCM
What is 2 structures that can give rise to headaches
400
Seizures, Focal Neuro deficits, Headaches, Cognitive deficits
What is the most common clinical features of a brain tumour? (4)
400
Accessory nerve, innervates SCM and Trapezius - test these muscles, Cervical rotation/flexion, shoulder elevation
What is Cranial nerve XI? What does it innervate? How would you test it?
400
False - only will cause pain if pressing on a pain sensitive structure or increasing cranial pressure
True or false: A brain tumour will always cause pain
400
Problems with reasoning, movement, planning, emotions, speech, problem solving resulting in personality changes, weakness, aphasia, apraxia
What is the presentation of a brain tumour in the Frontal Lobe
400
A- advance preparation
B- build a therapeutic environment/relationship
C- communicate well
D - deal with patient and family reactions
E - encourage and validate emotions
What is the ABCDE of breaking Bad News
500
30% are primary (of which, 40% are benign), 70% secondary in adults
In kids, most are primary
What percentage are primary vs secondary brain tumours in adults?
500
Test pain (pin prick vs dull), temperature (hot vs cold) along dermatomes
How would you test the spinothalamic tracts?
500
nociceptors detect stimulus → conversion of stimulus to an electric signal → C fibers and Aδ fibers carry afferent input to the dorsal horn of SC → secondary nociceptive neurons in the spinothalamic tract carry afferent input to the thalamus → pain perception and a response sent along efferent pathways to modulate pain
What is the pain pathway
500
Problems with orientation, perception and recognition of sensory stimuli or faces, understanding
What is the presentation of a brain tumour in the Parietal Lobe
500
autonomic, endocrine changes
Medulla
CTZ
NTS
gastric dysrhythmias
What is the pathophysiology of Nauseau
(just name some big pathways involved)
