Neuro Flashcards
Antenatal risk factors of CP?
- Chorioamnionitis
- GU/ resp maternal infection
Perinatal risk factors of CP?
- Pre-term birth
- HIE
- LBW
- Neonatal encephalopathy
- Neonatal infection
- Maternal infection
Post-natal risk factors of CP?
- TBI <3 years old
- Meningitis
Spastic CP?
70% of CP
- UMN lesion
- Reduced GABA sensitivity (reduced inhibition)
- Increased tone from UMNs
Dyskinetic/ athetoid CP?
- Damage to basal ganglia
- Lack of movement regulation
- Dyskinesia/ chorea
Ataxic CP?
- Cerbellar damage
- Clumsy, poor coorination
Early motor signs of CP?
- Fidgeting
- Lack of/ abnormal movement (head control, crawling, walking)
- Feeding difficulties
- Tone abnormalities
Delayed milestones CP?
- Not sitting 8 months
- Not walking 18 months
- Hand preference before 1 year
Red flags for other neuro conditions, not CP?
- No CP risk factors
- Family hx of degenerative neuro disease
- Loss developmental milestones
- Focal neurology
What is the follow up for patients at risk of CP?
Follow-up programme by MDT for children up to 2 years
Surgical management CP?
- Dorsal rhizotomy - Electical stimulation reveals nerve root causing spastic symptoms, nerve root is severed (spasticity)
- Intrathecal baclofen (GABA agonist) (spasticity)
- Deep brain stimulation (dystonia) - electrodes placed in the brain, neurostimulator placed under the skin of the abdomen, regulates movements
SALT management CP?
Eating/ drinking/ swallowing
- Individualised plan for eating, drinking and swallowing
Language
- Posture
- Breath control
- Voice production
- Rate of speech
- Augmented and alternative communication systems (eg. pictures, symbols, speech generation etc)
Management of saliva control CP?
- Anticholinergics (eg. glycopyrronium bromide, transdermal hyoscine hydrobromide)
- If Anti-Ach contraindicated botox A injection salivary glands (refer to specialist)
Management bone mineral denisty CP?
- Dietary intake Ca2+ and vit D
- Active movement/ weight bearing programme (physio)
- Dietarty advice (dietician)
Pain mx CP?
- Stepped approach simple analgesia (WHO pain ladder)
- Specialist referral
Sleep disturbance CP?
- Sleep hygiene
- Trial melatonin
Visual impairment mx CP?
- 1/2 children
- Opthalmological assessment
What % CP hearing impaired?
10%
What % CP chronic constipation?
60% (3/5), give laxatives
What % CP epilepsy?
33% (1/3) give anticonvulsants
Simple febrile seizure?
- <15 minutes
- Generalised tonic-clonic
- No repeats within 24 hours of the seizure
What are the excitatory and inhibitory neurotransmitters in the brain?
Excitatory: glutamate, binding to NMDA receptors causing Ca2+ influx
Inhibitory: GABA, binding to GABA receptors causing Cl- influx
What are the theorised mechanisms of febrile convulsion?
- Increase in body temperature increases neuronal excitability
- Increased temperature causes hyperventilation leading to respiratory alkalosis which increases neuronal excitability
- Cytokines IL-1 stimulate NMDA receptors
Risk factors febrile convulsion
- Genetics (family hx)
- Age (6m-5yrs peaking at 12-18 months)
- Rapidly increasing fever
- High temperature (always >38)
- HHV-6 (roseola)
- Vaccines (MMR, stimulate immune system)
Why don’t antipyretics decrease the risk of febrile convulsion recurring?
Theorised due to the rapid increase in temperature, when temperature is high and antipyretics given the rapid increase has already happened
Management during febrile convulsion
- Protect head (cushion)
- Once seizure stops, put in recovery position
- Time seizure
- > 5 minutes, call ambulance
