Neuro Flashcards
1st line investigations in suspected shaken baby syndrome
CT scan FBC LFT Clotting Toxicology screen Urinalysis LP - if stable and not contraindicated
Main cause of febrile convulsion
viral
management of a febrile convulsion
antipyretics
safety net
educate and reassure parents
Treatment in a febrile seizure if it lasts >15 mins
benzodiazepine
how often do febrile convulsions recur?
1 in 6
what is the prognosis in most with a febrile convulsion?
good neurological outcome
key blood test in an afebrile seizure
blood glucose
Investigations in afebrile seizure
Blood test - FBC, U&Es, other mineral, vit D, Metabolic work up Toxicology AED levels ECG EEG
Presentation of lyme disease
erythema migrans fatigue lymphadenopathy myalgia headache fever
neurological manifestations of lyme disease
meningitis
facial palsy
cerebellar ataxia
how is lyme disease confirmed
antibody testing
treatment for lyme disease
amoxicillin or doxycycline
genetics of neurofibromatosis
autosomal dominant disorder
for diagnosis of NF1 need >2 of
cafe au lait spots axiallary / inguinal freckling bony lesions 2+ neurofibroma tumours 1st degree relative with NF1 >2 harmatomas optic nerve glioma
NF2 most associated with
CNS tumours
definition of cerebral palsy
fixed neurological disorder
affects motor and posture mainly
caused by non progressive injury to the developing brain in the first two years of life
80% of CP due to
antenatal factors
3 factors causing CP
antenatal
hypoxic ischaemic injury during delivery
Post natal factors
3 types of cerebral palsy and what has been damaged
spastic- cortex damage
extrapyramidal - basal ganglia damage
ataxic - cerebellum damage
define status epilepticus
seizure or repeated seizures lasting >30 mins without regaining consciousness
MR brain done in suspected cerebral palsy?
to rule out neurodegenerative or metabolic conditions
- if aetiology unclear
- signs of regression
