Neurology Flashcards
What does head circumference measure?
Brain growth
How does hydrocephalus present physically?
Increased head circumference
What causes hydrocephalus?
Excess production or blockage of drainage of CSF
Core signs of neurological conditions
Developmental delay
Floppy infants
Acute confusion
Sleep disturbances
Disturbed vision/hearing
Numb/tingle/weak
Abnormal behaviour
Psychomotor regression
Speech disorders
Back pain
Peripehral weakness
Funny walk, foot deformity
Eye movement abnormalities
Abnormal facial movements/sensation
If problem with motor cortex what causes?
Problems with muscle power and tone
General physical neurological exam. Cushings triad, signs of raised ICP
Anterior fontanelle - bulging, depressed
Signs of raised ICP - irritability, confusion, decreased consciousness, posturing, bulging fontanelle/enlarged OFC, sun setting
Cushings triad - wide pulse pressue, HTN, bradycardia
Neuro exam
AVPI
GC if older
Pupils equal and reactive to light and accomodation
Head injury 0 brusiing, blood, CSF from nose/ears, open wounds
Meningeal signs
Cranial nerves
Limbs: bulk, tone, power, co-ordination, reflexes, gait
What is dravets syndrome
Severe myoclonic epilepsy of infancy with recurrent febrile or afebrile hemiclonic or generalused seizures or status epilepticus when previously well
Resistant to antiepileptics
Developmental arrest or regression
Up to 15 months age onset
15% mortality
What is lennox gastaut syndrome
What is juvenile myoclonic epilepsy
Teen years
Early morning myoclonic jerks, arms and shoulders
GTC later evolve
Autosomal dominant
What is panayiotopoulos syndrome
Common multifocal autonomic childhood disorder
3-6 years onset
Prolonged seizures, auatonomic smyptoms eg ictal vomitting
Occipital dominance with shifting focus on EEG
Confused with non epileptic disorders
Benign rolandic epilepsy
Also benign focal epilepsy
Nocturnal seizures - twitching, aphasia
4-10 years, more common in boys
Benign childhood epilepsy with centretemporal spikes
Older children - focal or generalised seizures
Large spikes on EEG - Rolandic area (dont confuse!!)
Not ass with structure, excellent prognosis
What to do when EEG gails
Sleep/sleep deprication EEG
When do MRI for epilepsy
> 2 seizures
Focal onset
First line Antiepileptics dont work
