28
What are the end pieces of lower neuro exam?
Romberg and Gait
29
What does a positive romberg test indicate?
Cerebellar lesion if you wobble when eyes open
30
In romberg test if positive once eyes closed what is the indication?
Sensory ataxia
31
What is positive pronator drift sign a indication of?
UMN lesion--\> the arm will pronate and fall
32
What lesion causes lose of rebound phenomenon?
Cerebellar lesion
33
What does clonus indicate?
UMN lesion
34
What is the cerebellar symptoms?
Dysdiadochokinesis Ataxia Nystagmus Intentional tremor and past pointing Slurred speech Hypotonic
35
What causes UMN lesion?
Blunt trauma, stroke and tumour
36
If you have a UMN lesion is extension or flexion weaker in a) arm b)leg
A) Extension weaker than flexion B) Flexion weaker than extension
37
Explain the grading power?
5= normal 4= slight weakness of power 3=movement possible against gravity but not resistance 2= movement possible if eliminate gravity 1= slight movement 0= no movement
38
Describe the reflex ladder?
0= absent += present with reinforcement needed 1= present but dappended 2= normal 3= increased 4= clonus
39
What is the SNOOP mnemonic for red flag of headache symptoms?
Systemic symptoms--\> fever , neck stiffness Neurological symptoms--\> ataxia, pralysis Onset recent or recurrent--\> important for \<40 Other associated symptoms--\> with trauma, Past headaches --\> different or same
40

o First dorsal interosseous (FDI) (index) o Abductor digiti minimi (ADM) (small finge)
41
What is the finger nose test assessing?
If their is any past pointing or intentional tremors
42
What is rebound phenomenon testing?
Your antagonist muscle If you fail to stop your hand then you have a cerebellar disease

52
What is the most common syncope?
Vasovagal syncope
53
What does vasovagal syncope occur?
o Occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress

60
What are the key associated symptoms for headache?
Fever=meningitis Rash= meningitis Nausea +Vomiting= ICP Worse on lying down or coughing=ICP Neck stiffness =menin Fits/faints Loss of consciousness Blurred vision Jaw in the temporal region/jaw when moving Photophobia Thunderclap= worse after 5 minutes (SAH) Disrupting the sleep= ICP Any weakness in the body or face= stroke
61
In a headache history what questions do you ask about associated causes of the headache?
