Intro Flashcards
BBPV- symptoms, test used
- Sudden sensation that you or sourondings are spinning (when head turned quickly)
- One of the mc types of vertigo
- Tested using dix halpoke maneuver
Acute vestibular neuritis- exams used
Vestibule is inflamed
- HINTS exam-> look for nystagmus
- Cover/uncover test (look for nystagmus)
Screening for stroke questions
Dizziness Dysarthria Diplopia Dysphagia Drop attack Ataxia Nausea Nystagmus Numbness
What are some ddx for weakness
ALS Muscular dystrophy myasthenia gravis vid d def hypothyrodysim
Tone of UMNL and LMNL + reflexes
UMN- Spastic, increased reflexes
LMN- Flaccid, decreased reflexes
What does the lat corticospinal tract carry, ant spinothalmatic and post coloumn
lat spino-pain and temp
ant spino- crude touch/pressue
post- Proprioception, vibration, light touch
what side would the lesion be on in a cerebellum lesion
same side as lesion
What is dysmetria vs dysdiadochokinesis
dysmetria- pt misses target when aiming for somthing
Dysdiadochokinesis- unable to perform rapid alternating movements
when is a resting tremor seen vs a tremor when moving
Cerebellar tremor seen when moving whereas basal ganglia tremor during rest
What is radiucular loss, mononeuropathy, poluneuropathy
radicular- motor/sensory loss to specific dermatome
Mononeuropathy- motor/sensory loss to specific peripheral n (ex carpal tunnel)
Polyneuropathy- glove and stocking type loss (more common in diabetics/ vit def)
When would spacisity happen and characteristics of it
corticospinal tract damage
-unideirectional and velocity/amplitude dependent (faster = harder to move)
When would ragitity happen and characterisitcs of it
Extrapyramidal damage (basal ganglia) -Bidirectional + not velocity/amplitude dependent
What type of disorders result in decreased or absent reflexes
Disorders of sensory limb, LMN, NMJ, muscle itself
Examples of disorders that result in decreased/absent reflexes
- diabetes induced peripheral neuropathy
- Space occupying lesion
- myasthenia gravis
- Polymytosis
- Motor neuron disease
What areas are affected in an UMN lesion
spinal cord injuries, diseases of motor cortex
